A 'cleaner' way to turn off kernel mode setting for Intel i830m video

| | Comments (0) |

My laptops using Intel 830m (aka i830m ... aka 82830 CGC) video don't like kernel mode setting. They don't work with it.

But turning it off, they work wonderfully with no xorg.conf in anything with a 2.6.32 Linux kernel — and that means Ubuntu Lucid (currently in Alpha 3 stage, though I'm using the Alpha 2 image at the moment) and Sidux 2009-04 (and presumably Debian Squeeze, the current Testing release for the distribution).

Until now I've been turning off kernel mode setting in the boot line with:

i915.modeset=0

I just discovered, tested and confirmed that this boot parameter does the job just as well:

nomodeset

The latter's a bit "cleaner," don't you think. I promised in a comment that I would look into bugs related to this problem, but things look in a whole lot of disarray. Some people submit so many log files, outputs and other things that I wouldn't have the expertise to assemble in a dozen years. Others haven't yet landed on the solution I've written about in a couple dozen of these entries.

So unless someone out there can direct me to the "best" bug in either Debian, Ubuntu, Xorg or the Linux kernel itself, I'm gonna stay out of it and just continue writing about it here.

Am I the only person out there with not just one but THREE laptops using the Intel 830m chipset?

If not, either of the two boot parameters mentioned above make the X problem go away. I'm sure kernel mode setting is a wonderful thing, just not for this particular graphics chipset.
