How to force resolution (xorg.conf settings)

[Guillaume.l]

Hi!

Since I've reinstalled Ubuntu (with the current 8.04 version), I can't force the screen resolution (I want 1280*768 and the screen display is still 1024*768). I tried to edit the xorg.conf file but it doesn't seem to influence display configuration, whereas it was possible with previous releases of Ubuntu (and 8.04 updated from 7.10).

I also tried to use the xserver configuration tool (dpkg-reconfigure xserver-xorg), but unlike previous releases it asks for keyboard and mouse settings but nothing about display.

Guillaume.

What is the name of your graphic card ? And why do you want to change the resolution ? Can you first give us your system specification?

My graphic card is an old ATi Rage Pro (ATI Technologies Inc 3D Rage Pro AGP 1X/2X (rev 5c)).

I need to change the resolution because it doesn't fit to my monitor (16:9 monitor).

Do you need any other of my system specifications ?

HI and have you tried the command
gksu displayconfig-gtk and adjust there.

Thanks overdrank.

I saw a "Large Monitor" checkbox, I checked it, and it allowed me to choose 1280*768 resolution, but display is still a 1024*768 res.
