Bug#427811: xserver-xorg-video-intel: Occassional hard freeze switching from graphics to text mode

[Ariel Garcia <garcia@iwr.fzk.de>]

Hi again,

bad and good news:

the bad: 2:2.1.0-1  still has the same problem, switching to console is ok 
before starting kde, freezes/messes up the screen completely after log in. 

the good: i now analyzed the kde startup by steps and found the 
responsible:  it is the  RANDR  extension stuff.
Actually, if i move away  the xrandr  executable (which is called by the 
kde startup if the "apply settings on KDE startup" is enabled in the 
Display configuration)  then the switch to console works fine!
(still to try suspend to RAM though).
The call to xrandr activating the problem is very simple and doesn't do 
anything strange, just keeps the defaults:
   xrandr -s 1400x1050 -r 60 -o 0

Should this probably be reported upstream? Do you take care Brice or shall 
i? where, Xorg or drm?

Note: last time i reported that  2:2.0.0-5 seemd to work after just a few 
vt-switch tries and one susp2ram... but then it hanged in the next 
suspend, so probably it is always the same problem there + some 
randomness. In 2.1.0 with randr it was hanging systematically.

Currently i am running 2.6.21.6   + the latest (as of today, 7.7.07) drm 
and i915 modules from the git repository.
The i915tex  module is NOT being loaded:
  (II) AIGLX: Loaded and initialized /usr/lib/dri/i915_dri.so

Cheers, Ariel
