[Bug 566379] Re: [i855] X doesn't start with kernel 2.6.32-21 unless passing i915.modeset=1

[Christine Liebig]

Laptop: Acer TravelMate 290 (292LCi to be more specific).
Graphics: VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device
Kernel: 2.6.32-22

Progress report: 
I have now successfully upgraded from Hardy. I followed the instructions for Workaround A at https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes and Lucid boots fine now, but playing videos causes an X freeze and Desktop effects can not be enabled. (One time selecting desktop effects caused a funny error: after a bit of flickering the screen went back to normal, but all letters in menus were no longer from the latin character set, but some unknown set (could have been Thai as far as I can say, but maybe just a random mix). However, judging from the lengths of words it was still in the English language setting and I was able to recognise the logout option. Logging out and in again put everything back to normal. Unfortunately, I cannot reproduce the bug.)

Following Steve's instructions, i.e. permanently setting the boot option
"i915.modeset=1" in the /boot/grub/menu.lst, gives exactly the same
result.

X freezes whenever I start a video (e.g. using the example-content video
"UbuntuIsHumen.ogv" with Totem Movie Player, but also with a random .avi
and xine). Flash videos with Firefox are fine. Movie Plazer with sound
files also works fine.
