Change my max screen resolution


During my installation of ubuntu it asked me my max screen resolution. I chose the wrong one! thankfully it was lower than it actually is so it didn't break my screen. However now I can't make it go up any higher than i set in the installation. how do I change this?

in xorg.conf,

the section "screen" set the maximun screen solution. However, you may need to make sure HorizSync and VertRefresh in "monitor" section are correct as well.

here's my settings, i increased mine by 15 to give me a refresh of 75Hz
if u wish 85Hz increase by 20 but please don't go to high as that will completely lock u out of the x-server ...

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 28-64
VertRefresh 43-87

still doesnt work

I'm running Ubuntu 5.04 on a Dell 700m (laptop)

I did as you said, and found xorg.conf
the problem is that xorg.conf shows the correct resolution (1280x800) and even the correct device (855GM Integrated Graphics)

so why does the resolution in xorg.conf differ from the resolution that I'm literally looking at? I cant seem to change it

ps: the screen resolution is stuck at 1024 x 768 with no options to change it

Have a look at /var/log/Xorg.0.log

It will tell you what is happening. What may have happened is that the monitor is not responding adequately (e.g. dt wrong frequencies) and subsequently the card is finding its own way of displaying something - which is not the way you intended too,..

Anyway, start with the logs and come back with teh result :-)

I recently posted on this forum a xorg.conf file which worked well for me and to some other person too.
The title is:
"Intel 82845G Graphics Controller"
I also had the same problem but finally, after many changes on the config file I managed to get the resolution I wanted.
Hope the xorg I posted helps.
