[Sussex] Resolutions

[Ronan Chilvers]

Hi folks

Can anyone shed some light on an annoying X resolution problem?  I'm
using a flat screen monitor at work (HP 1702 TFT) which is capable of
1280x1024.  The machine used to have Mandrake 10 on it which happily
drove the monitor at the right resolution.  However since installing
Ubuntu, I can't get the resolution higher than 1024x768 without it
using a virtual desktop space (ie: the desktop extends out beyond the
monitor ), as if the highest resolution was 1024x768.  I've tried
generating some Modelines for the full resolution, using the monitor
specs from the HP site with no joy - same thing happens.  I know it
will do the full resolution because it has quite happily in the past.

Unfortunately I don't know the Mandrake 10 X server version which might
have helped, but the current one is the standard Ubuntu Hoary xorg
version 6.8.2. The graphics card is an on-board Intel 82865G PCI device
using the native X driver's built resolutions / modes which does list
1280x1024 as supported in Xorg.0.log.  However the log also contains
the line

(II) I810(0): Not using built-in mode "1280x1024" (width too large for
virtual size)

Any ideas anyone?  If you need to know anything else let me know. I can
attach over xorg.conf files, etc as required.

Cheers

Ronan
