[gentoo-user] X starting in 640x480 only

[Christian Herzyk <gentoo@herzyk.de>]

Hi,

when I rebooted my PC yesterday my X did not come up (I made an error 
with etc-update after the resent baselayout upgrade and removed the 
DISPLYMANAGER setting). After fixing that my X came up, but only at 
640x480.
During the last days I did not change anything connected to X on my 
system and rebooted it several times without problems. I am running a 
x86 system with Intel Corporation 82915G/GV/910GL Express Chipset Family 
Graphics Controller and 99% stable packages including Xorg 7.1 (the 
unstable ones are apps, nothing with X).
It ran totally fine until yesterday.
I tried a lot, remerged X and experimented with settings.
I am still not sure what the problem is.

There are some things that strike me:
In the Xorg log I find:

(WW) I810(0): xf86AllocateGARTMemory: allocation of 13409 pages failed

several occurences of that with different page counts
.
And this one:
(II) I810(0): Not using mode "1280x1024" (no mode of this name)
(II) I810(0): Not using mode "1024x768" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (640 -> 
1024).
(--) I810(0): Virtual size is 640x480 (pitch 1024)
(**) I810(0):  Built-in mode "640x480


Any idea what the problem is?


Thanks.

Christian
