[Bug 383345] Re: [i945gm] dual screen not working with virtual resolution enabled: just a blank screen with a mouse pointer
@Laurens
my comments 42-43
compiz works even on that 1px.
In jaunty I was on my daily work on 1024+1024 with compiz.
Since Karmic I use 1024+1280 without compiz.
The switch from compiz to metacity on changed resolution is without
problems (gnome always starts with black screen 2048, I have keyboard
shortcut to 1024+1280 - xrandr).
Kwin nearly always crashes the whole xserver on this resolution change.
Sometimes (20%) it's succesfull in survival after compositing is auto
turned off.
The maximum size of a 3D texture on i915/i945 is 2048x2048px.
Since compiz is one big texture, it is supposed to work on that resolution.
(Somewhere I red, that compiz developers plan to make compiz
multitextured. I that case also older HW would manage big resolutions.
Don't ask me how. I just red it on some compiz blog.)
