Recently in Wolvix Category

As an experiment, I decided to bring my Evolutionary Computing presentation on making the journey into free, open-source software — a slide show originally created in OpenOffice Impress 2.4 — into Google Docs, which happens to have a presentation app in addition to the better-known Docs and Spreadsheets components.

I revised the presentation — taking some things out, adding others and providing some updates on what I'm doing — and output it as a PDF.

Evolutionary Computing (revised July 2009)

Interesting note: I believe that no previous entry on this blog has been filed under so many categories. (And I've been considering dumping Categories entirely and just using tags ...)

I've done this sort of thing before, but luckily somebody else is comparing the Xfce environments of Debian Lenny and Xubuntu/Ubuntu.

Results are not surprising and are in line with what I found over a year ago when I did a major comparison of everything from Xubuntu and Debian to Slackware and gOS, as well as Wolvix and standard Ubuntu.

Back then, Slackware and Debian with Xfce are indeed very, very fast systems. And while I didn't test them at the time, I expect ZenWalk and Vector with Xfce to perform as well or better.

That said, I've always liked the look of Xubuntu (especially in the 7.04-7.10 era), but it does run a good deal slower than other Xfce-equipped systems — and in fact didn't do much better than Ubuntu with GNOME in my test. Thus I've pretty much just used Ubuntu when I want it, although I did have some issues with crashing on my Gateway laptop that appeared at the time to be solved by adding Xubuntu to the install and running Xfce instead. (Since then, we've been running Ubuntu with GNOME — version 8.04 — on the Gateway, and it has been running very well.)

Despite all of this, I still have two Ubuntu 8.04 installations running right now. Sure Debian and Slackware are faster, but I'm quite happy running GNOME, and I find performance in Ubuntu more than acceptable. But what keeps me running Ubuntu is the ease of installation, configuration (I'm running with no xorg.conf — and perfect video out of the box — on both installs) and patching of the system. Despite all the talk of Ubuntu shipping before everything is "right," I can't remember suffering from a broken app or feature in recent memory. And it seems that even if a new app isn't available for some reason in the Ubuntu repository, the developers behind it are quick to create a package that's designed to run in Ubuntu (even though I prefer to run what's in Ubuntu's own repository).

All things being equal, I prefer Debian, but since Lenny all things have not been equal on my Gateway and Toshiba laptops (both made around 2002-3), with which I've had unsolvable video issues in both Lenny and at least on the Gateway in Slackware as well. No amount of tweaking xorg.conf, installing new drivers, etc., would make Debian Lenny play well with the Intel video in the Gateway, and when a quick Lenny install on the Toshiba brought up the same issue, I ran quickly to the welcoming, trouble-free arms of Ubuntu. Of course OpenBSD 4.4 is running virtually trouble-free on my second, identical Toshiba Satellite 1100-S101 laptop, and if OpenBSD can get xorg running perfectly with no configuration (and no xorg.conf needed), you'd think that Debian and Slackware could do the same.

In all fairness, I haven't tried Slackware again since 12.2 came out, so maybe things have changed, and I also haven't tried Lenny since it went stable (my experience was during the three or so months leading up to that point). Put simply, Ubuntu worked, so I use it.

And as I've also said before, many of the replies to requests for help in the Ubuntu Forums might be less than helpful, but the sheer volume of those messages means that finding the answer to your question/solution to your problem not just for Ubuntu but also for Debian is easier than you might think.

I haven't tried ZenWalk in a very long time, but I'm thinking about it.

When I first started using Linux, ZenWalk was one of the first systems I played around with. I had a nice install at one point, and that particular machine would install the old version of ZenWalk at the time but not whatever the new version happened to be. As a last-ditch effort/experiment, I tried to upgrade the old system, but since ZenWalk pretty much stopped supporting my old system but kept everything in the same repository, the upgrade pretty much bricked the install.

Still, ZenWalk is a super-fast system with excellent hardware detection and less geeky pain than in Slackware, upon which Zenwalk is based.

Then there was/is the controversy about whether or not ZenWalk was complying with the GPL when it didn't make source code available. (I can't find a good item to link to, but the issue was discussed hotly and at extreme length in the LXer forums.)

But with every new ZenWalk release, including the current beta of version 5.4, I'm tempted to give ZenWalk another try.

I have old hardware, love fast systems, love the default Xfce desktop environment (which is right there in Slackware but somewhat of a red-headed stepchild to KDE), love the look of ZenWalk and appreciate its very extensive repository.

When it comes to Slackware-for-the-rest-of-us distros, I've been more than partial to Wolvix, even though I worry about it's relative speed (I get the feeling it's slower than ZenWalk, Vector and plain ol' Slackware, though I have not much to back this feeling up), I worry about whether or not I've updated the kernel properly (it requires some hackery in slapt-get and/or Gslapt that I'm a bit unsure about), and I worry that Wolvix in general isn't as up to date as it could/should be.

But Wolvix — most of it, at leat — continues to be updatable via slapt-get/Gslapt without the whole thing going to hell.

In contrast, if I were to install ZenWalk today, I'd be sure to create a separate partition for /home (which I always do anyway these days) so I could wipe and reinstall between releases. Or I could do the not-unthinkable and dual- or triple-boot a bunch of Slackware-derived distros on a single box and see how I feel about it in a month or so.

I've got a laptop that needs a FOSS OS, and while I've been thinking Debian or Ubuntu because that's my "default" choice, I may give ZenWalk a try just to see how it runs. All of these new features do look like things I'd enjoy having:

Kernel 2.6.27.10 with gspca (supports many USB webcams)

XFCE 4.6 (beta2, already very stable)

Faster boot (tunned init scripts, with realtime I/O scheduler)

PAM authentication has been added to the system

Wicd is becoming the main network configuration tool

Improved suspend/hibernate, with XFCE Power Manager

new Netpkg with orphan dependencies and "offline operation" support

New Zenpanel with integrated Disk Manager, Wifi and Wired Network Manager

Gksu keyring based desktop granting system

New artwork

Many new applications

And it looks (from this 5.2 announcement) that the license-violation issue is at least beginning to be taken care of:

Source repository: many faithful users asked us to provide an online source repository rather than sending source Dvds on-demand. So we have been working on a mechanism to allow the development team to instantly publish source tarballs for any new package we release. This source repository is now 100% ready for ISO packages, and the contributed packages (aka "extra") source repository is being populated actively.

Zenwalk's Community Spirit: As the community thrives, Zenwalk now has a web-accessible Package Database and a conveniently arranged User Repository. Please also have a look at the Zenwalk Companion - a guide to the extra packages available to Zenwalk. Please see the zenwalk.org website for more information, and welcome to support.zenwalk.org for bug reports and friendly discussion between Linux purists :)

Of course while I love systems that are updated forever (as in Wolvix), I'd love even more to see a new version of Wolvix to appear — and if that happened, I'd be a very happy camper, indeed.

It's been a long time since I ran ZenWalk, and I can't say how its application mix would meet my needs, but the thing I like so much about Wolvix is that it has virtually everything I want or need as far as applications go, and its installer and control panel also match my needs better than just about everything else out there, too.

Not that I've run Wolvix in the past six or more months, due to a combination of the issues I raised above, then the time I spent running Debian and Ubuntu, and now having my "main" laptop run OpenBSD, which I've been quite happy with by the way.

But some time back in the Linux world, and not necessarily in Ubuntu or Debian, is starting to sound pretty good.

I feel like I'm booting children off a train.

Sure I've had my times when I installed a GNU/Linux distribution, used it for a couple of hours and then pulled it.

But for the past year or so, I've stuck with Debian, first with Etch and then Lenny since Etch went stable in April 2007. And when Ubuntu rolled out its new LTS distro in April of this year, I installed it and have been using it since. My older Compaq laptop has been running OpenBSD 4.2 for over a year, and I've done two very satisfactory Etch installs in the past month or so.

But on my main machine, a 2002-era Gateway Solo 1450 laptop, there's been trouble in GNU/Linux paradise.

After fighting with Debian Lenny for months over the Gateway's screen-refresh problems (which basically render much of that screen unreadable after a half-hour or so of use), I finally decided that I couldn't stick with the Testing branch of my favorite Linux distro on its road to becoming Stable. While many other problems cropped up and were mowed down either by me or the Debian Project itself, this last issue just wouldn't go away. And since I see not even one other person with this same problem, I fear the issue will never be resolved. I don't even know which package to file a bug against.

Remember when I thought I fixed my random-screen-freeze problem on this same laptop in Ubuntu 8.04 LTS? I thought that turning off automatic suspend in GNOME fixed the problem.

That didn't work. I still have random freezes. And I can't really blame it on the power plug because I've been in conditions where that plug does not move, and moreover these freezes never happened in Debian (when my screen image was not totally disintegrating, that is).

I was trying to get some pre-election work done on http://www.dailynews.com, and when I found that I didn't have the Java runtime installed (and needed it), I moved over to Ubuntu 8.04. In a half-hour, I had three unrecoverable crashes.

Again, I haven't heard of this happening to anybody but me.

I have TWO surplus laptops waiting in the wings. I'll see if any of them perform as well as or better than this Gateway. But whatever happens with those two machines, the Gateway will remain in service.

Once I decided to let go of Debian Lenny, I thought I would try Fedora 9, but when the live CD wouldn't let me install it, I turned to CentOS 5.2 — the free version of Red Hat Enterprise Linux — instead.

I first booted the live CD, then used the live CD to do a network install (NOT from the live environment but as a boot option). Once I determined that an http install wouldn't work but an ftp install would, I was off and running.

I've been testing CentOS 5.2 for about a week now. I've been slowly solving problems (adding things like Pidgin and Flash), and at this point I can say that CentOS 5.2 boots quickly, seems as snappy on this hardware as Ubuntu or Debian and runs extremely well.

I have yet to see a bug, and it has never crashed.

I have a full review and how-to for CentOS 5.2 in the works.

I hadn't anticipated replacing Ubuntu 8.04 LTS. I've had trouble with Ubuntu on this laptop since 7.04, and I've gone back and forth with it. Until I pulled it last week, I always had either Debian Etch or Lenny running on it. I've run Puppy 3.01 from live CD and the Slackware-based Wolvix Hunter — both with few problems.

The 2.6.18 kernel in CentOS 5 has always run better than any other on the Gateway. Other distros that share this kernel (albeit in slightly different versions) include PCLinuxOS 2007 and Debian Lenny.

And with support for RHEL/CentOS 5 slated to last a very, very long time, the fact that it runs so exceedingly well on this hardware gives me a true long-term solution.

I suspect that if I rolled the older Ubuntu 6.06 LTS — which has a little over seven months of support left before it EOLs — onto this laptop, it would run flawlessly. But it's packages are even older than Debian Etch's ...

As it stands right now, I'm going to stick with CentOS 5.2, and as much as I don't want to do it, I need to drop Ubuntu 8.04. I love Ubuntu — its philosophy and package mix, if not its brown color scheme. But I can't deal with the random freezes (after which ctrl-alt-backspace and ctrl-alt-delete are useless and only a hard reboot will work).

Aside from the screen-refresh problem, Debian Lenny was doing great. It improves on Etch in many, many ways.

I could see myself returning to Etch, which will have a full year of support as Debian's Old Stable distribution once Lenny is declared stable.

Whether I continue using this laptop or not, it has to run my daughter's educational games (GCompris, TuxPaint and Childsplay), and it has to be as stable as possible.

With Etch on the Gateway, I had trouble with the Alps touchpad, but since those problems were so easily solved in CentOS 5.2, perhaps I've learned enough to figure them out in Etch, where in addition to the touchpad-tapping issue the speed differences between the touchpad and a plugged-in USB mouse were more than a little incovenient.

I remember PCLinuxOS running as well as anything during the week or so I used it. I wonder how much support is left for the 2007 edition of that distro. The hype over PCLinuxOS has really slowed down over the past year, but I still think it's a very solid distro (based on Mandriva but with Debian-style apt and Synaptic package tools).

I've had trouble with X in Slackware on this platform, never seeming to get xorg.conf right, although Slack-based Wolvix runs perfectly for some reason. Slackware-based ZenWalk has all the packages I need and during the brief times I've run it has show itself to be extremely fast.

And since I'm running with separate /home partitions for both distros on this PC, switching those distros in and out should be less traumatic than in the past.

Even though I've taken great pains, after the fact (when it's harder to reconcile), to keep my user accounts' UID and GID numbers in Debian- and Red Hat- based distros compatible, I will probably dual-boot Fedora and CentOS for a while just to see how they match up on this hardware.

Depending on how things go with CentOS 5.2, I could eventually simplify things and do the unthinkable: not dual-boot anything.

CentOS seems terribly boring. But ever since Red Hat rolled a bunch of newer apps into its RHEL 5.2 (the base for CentOS), including Firefox 3 and OpenOffice 2.3, I've seen it as a very real alternative for the desktop.

And I neither expected it to run so well or for Debian and Ubuntu to run so comparatively poorly on this specific hunk of hardware.

If I had 10 test machines and Debian or Ubuntu ran flawlessly on them, I would be telling a different story, but from the perspective of this 6-year-old Gateway, RHEL/CentOS is pulling way out in front.

Here's the deal: I've been fighting with Debian Lenny for months on The $0 Laptop (Gateway Solo 1450), where I have everything running great except for my persistent problem with screen refresh in X. I've replaced the Intel i810 driver with the plain Intel driver, I've tweaked everything that can be tweaked in xorg.conf.

I can't really get work done while my display is slowly disintegrating during the course of a computing session.

I'm already running Ubuntu 8.04 LTS as the main distro on this system, and I've been thinking about what to do for the second distro. I'd go back to Debian Etch, but I had problems with the speed of the USB-connected mouse vs. the Alps touchpad, plus problems controlling the touchpad on its own.

In Lenny, the problems I've dealt with (and mostly solved) over the past six or more months have included suddenly disappearing sound (fixed with manually installed ESS Allegro modules), and an Epiphany browser that would always start in offline mode (fixed with a modification to Gconf2, if I have the name of the app right).

Nothing major — and nothing that couldn't be fixed with some help from either the bug reports themselves or other helpful people on the Web.

But this screen-refresh problem persists. I keep hoping that a routine software upgrade will take care of it, but that hasn't happened in countless xorg, driver and kernel updates. I don't think it's going to happen, either.

If you're running something that's very popular that catches the attention of developers (like the Asus Eee PC), chances are good that issues will be resolved. But I can't imagine any developers anywhere are paying any attention whatsoever to my 2002-era Gateway laptop. I'm no C hacker, so there's nothing much I can do, either.

I love Debian. I'm running two newish Etch installs right now (one PowerPC, one i386), and I could very well add a third with my $15 Laptop (Compaq Armada 7770dmt), or even more to a couple of testing desktops I have waiting in the wings. Whenever Lenny goes Stable, Etch will have another year's worth of patches as Old Stable before it reaches its end of life.

Etch has been great, and Lenny has made dozens of improvements. But this one regression has made it very hard to keep my favorite distro on my main laptop.

So I have been thinking for months about what to do, all the while hoping that I could fix the X problem in Lenny.

First of all, I need to rewire the power supply plug. I think that is what is responsible for my intermittent freezes in Ubuntu (which don't seem to happen in Lenny, for reasons unknown). When I have the laptop on a desk, it never freezes, but when it's on my actual lap, as it was when I was trying to work on last-minute election programming yesterday morning, those freezes can really throw me off. I moved over to Debian, but I needed the Java runtime, didn't have it installed and didn't have the time to do that.

And then there's the video issue.

So I've been thinking, what should I install in place of Debian Lenny? I'm a big fan of long-term support releases, especially for older hardware, so I strongly considered CentOS 5, a clone of Red Hat Enterprise Linux 5. But the relative lack of consumer-oriented software had me worried. I could add the Dag Wieers repositories to deal with that issue, but even that repository doesn't cover everything I need.

Mandriva is also on the table, as is one of my favorite distros, Wolvix. The Slackware 11-based Wolvix is due for a new version soon. While its package mix addresses most of my issues, there are a few things that I can't easily find for it. And I worry in Wolvix's case (as well as Slackware's in general) about how long the kernel goes without getting patched.

I almost never see new kernels for older Slackware releases. I don't know if that's because they are unnecessary, but with patched kernels rolling into Debian and Ubuntu fairly regularly, I wonder why Slackware does things differently.

I'd run "regular" Slackware, but I had quite a bit of trouble getting X configured, and I'd rather use GNOME than KDE. I know there are GNOME projects for Slackware, but what I'm trying to do is install something that works well, comes together easily and has lots of available packages.

Given all the Mandriva fans on LXer, I considered it. I've used the Mandriva-derived PCLinuxOS and thought highly of it — and I may in fact go that way. The 2.6.18 kernel in PCLinuxOS 2007 (Debian Etch is also built on that kernel) is perhaps the best ever for the Gateway in that it controls the CPU fan with no intervention. The intervention needed in other kernels is slight (a single line in /etc/rc.local usually does it), but it's nice to have it done automatically.

Again, I'm not a huge fan of KDE, and I find that distros that are either KDE- or GNOME-centric tend to treat the other desktop environment as something of a second-class citizen.

I've had Fedora in the back of my mind for a while. Seeing all the packages available is very encouraging. And the Fedora community looks like a very good resource in terms of getting things working. I imagine that quite a bit of RHEL information would apply to Fedora as well, giving the distro an even deeper bench.

I'm not crazy about the length of support for a given Fedora release, which looks to be 12 to 13 months. I'd feel better with the 18 months that Ubuntu's non-LTS releases get, or even a full 2 years. Compromising on length of support is something I'm willing to do at this time for something that potentially gives me all the packages I want and that runs well besides.

As far as the availability of packages goes, Fedora acquits itself well. I have run it from the live CD before, and it seemed to do well on the Gateway.

In a slightly related matter, my install of Fedora 9 on my Power Mac G4/466 didn't go so well. The X configuration was horrible, and the distro ran much slower than Debian Etch on the same hardware. And Debian did a perfect X configuration for the internal graphics card and huge LaCie electron22blue monitor. Sure I could've used the information from the xorg.conf in Debian to properly modify the same config file in Fedora, but with such a performance hit, it didn't seem worth it.

Since the 1.3 GHz CPU and 1 GB of RAM in the Gateway offers much more power than the 466 MHz and 384 MB in the G4, Fedora seems to run fine on the faster machine.

And now that I have the Ubuntu LTS as my main distro (and hopefully a trouble-free one once I replace that shaky power plug), it's time to try something else.

First I need to keep copies of the xorg.conf, my CPU-fan script and rc.local from Debian Lenny in case I do a reinstall. Then I need to back up the /home files and consider adding a separate /home partition for the secondary distro (Ubuntu already has a separate /home partition).

Again, I'm not happy about the 13-month life cycle of any given Fedora release, and I really don't need a cutting-edge kernel for my not-cutting-edge hardware (unless, of course, it makes a cheap wireless adapter work), but with /home on its own partition, and Fedora installing GRUB on the root partition instead of the master boot record, with the GRUB on the MBR chainloading to the Fedora partition, it shouldn't be hard to roll Fedora out and something else in.

I could change my mind ... or not.

Update: OpenSUSE offers about two years of support per release, and that is enough to get me interested.

I'm downloading new OpenSUSE 11 and Fedora 9 ISOs now, and I'll burn them in the morning.
