Hello everyone,
Here is a list of all the problems and solutions gathered so far for random crash with intel graphics card on lucid lynx.
This post is for everyone who has an intel card and face random crashing with vertical or horizontal grey lines across the screen and also for anyone who has screen resolution issues.
To find your graphics card, use the below code:
you should see output like:
Code:
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
Random Crash issue:
To fix the random crashes, you have to tell ubuntu to use "vesa" driver instead of the "i915" that it uses for intel cards. You can also try to downgrade the "i915" driver and report back if it helps.
To use the vesa driver:
Code:
sudo gedit /etc/X11/xorg.conf
enter your sudo password and you will see either a blank file or with some contents in it. In either case, copy the following data to the file, save and reboot:
Code:
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
upon reboot, Ubuntu will use the "vesa" driver and your system will not randomly crash anymore.
Screen resolution issues:
install ddcprobe
Code:
sudo apt-get install xresprobe
then run command
if you have an output as below that shows edid fail:
Code:
vbe: VESA 3.0 detected.
oem: VIA P4N800 PRO
vendor:
product:

mode: 640x480x256
mode: 640x480x64k
mode: 640x480x16m

mode: 1600x1200x256
mode: 1600x1200x64k
edid:
edidfail
You will then have to lookup your monitor manual for HorizSync & VertRefresh and use them in the xorg file as below:
Code:
Section "Monitor"
Identifier "Configured Monitor"
HorizSync 30.0 - 70
VertRefresh 50.0 - 150
EndSection
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
Additionally, you can also specify resolution under the section "Screen" e.g.
Code:
SubSection "Display"
#Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
If you still have resolution issues, it might be because video card hsa not be allocated enough shared memory in the BIOS.
Can you have look at bios settings and increase it from 1mb to 8mb or make it higher than whatever it is set to.
Finally,
If you cant get to login screen, you get a blank screen or it freezes
At grub, Press E to edit and try adding "i915.modeset=1" after "quiet" without the double quotes. Also try remove the quiet and splash.
