Public bug reported:
Hi gyus,
Bhavani Shankar from launchpad refers me to you.
TIA,
Paul
-----------------------
Hi from a Linux newbie,
running Ubuntu on an old IBM Thinkpad iSeries 1200 Type 1161, videocard: ??,
tech spec says 'AGP 2x'.
Using Ubuntu 7.10: no problem, resolution 1024x768. Upgrade to 8.04 (using the
'Alternate' install image): ok.
After a system crash an I had to set up from scratch again using the 'Dektop'
install image. Since then the max. resolution is 800x 600.
Even the boot option 'vga=791' does not help.
Any help highly appreciated!
Paul

Hello
1. Go to System > Administration > Hardware Drivers and make sure your
proprietary video card driver is disabled (the box should be unchecked). Don't
worry, you'll enable it later; just not now. Reboot if necessary.
2. Go to System > Preferences > Screen Resolution and choose the highest
available resolution (usually 800x600). This will allow you to navigate through
Ubuntu more easily than at the lower resolutions associated with the
proprietary driver.
3. Go to System > Preferences > Main Menu > Applications > Other and make sure
the "Screens and Graphics" box is checked.
4. Go to Applications > Other > Screens and Graphics and select the option
which best describes your display (LCD or CRT, etc.). Do *not* use the "detect"
function. Also, do *not* choose "Plug 'n' play".
5. Now go back to System > Administration > Hardware Drivers and enable your
proprietary video card driver. You will have to reboot for sure this time.
Even after these steps, Try running displayconfig-gtk as root and modifying the
resolution
(to run the program as root Press Alt +f2 then type gksu xterm and then type in
the terminal displayconfig-gtk)
Regards
Bhavani Shankar.

Thank you for the super-fast answer.
ad 1,5: I have no propritary video card driver, 'Silicon Motion Lynx(generic)'
is used.
Did all the above, but when choosing [EMAIL PROTECTED] my screen shows only
garbage as if this reolution was too high, what is definitly not the case,
under Win XP and even 7.10 it was fine.
Thanks,
Paul
Or, Press Alt+F2 and enter:
gksudo gedit /etc/X11/xorg.conf
Scroll down to the Screen section and add the following lines:
SubSection "Display"
Depth 24
Virtual 1024 768
EndSubSection
Change 800x600 to your resolution
You should get something like this:
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Depth 24
Virtual 1024 768
EndSubSection
EndSection
Save the file and reboot.
If it wont help add the following line after the "Virtual" line:
Modes "[EMAIL PROTECTED]"
Do not forget to change [EMAIL PROTECTED] to your monitor parameters.
Save the file and reboot.
Hope this helps.
Bhavani Shankar.

Saw your 2nd propose right after answering the 1st one.
Tried that on too, but I better hadn't: After the change of xorg.conf and the
following reboot there is no more GUI, only a text based login prompt and after
logging in there the screen goes blank and that was it.
I booted in recovery mode and restored my original xorg.conf.
Regards,
Paul
