Ubuntu
xorg package

Screen resolution unavailable

Asked by chris friel

This is probably a fairly typical question.

I have done a fresh install of Ubuntu 8.10 and the native screen resolution for the monitor is not on the list of options. When I try to set the highest available the top and bottom panels are pushed almost entirely off the screen. Native resolution is 1440x900 and it defaults to 1024x768. I use the machine for graphics and 3D rendering so I need a high res 16:10 ratio.

I have tried to add a modeline but it failed - though I am kind of new to this, so it maybe wasn't done right. It seems that anything I try bumps it into Low Graphics Mode.

The xorg.0.log can be found here:-

I have an Asus VW 192s LCD monitor and an Nvidia 8800 GS running the nvidia-glx-177 driver. (Enabling the 173 results in Failsafe Graphics Mode)
The motherboard is a Gigabyte GA 945 GCM(X)-S2

I have tried the Xubuntu Live CD and it seems to be displaying at 1440x900 so I am hopeful that it can be fixed for Ubuntu.

I hope you can help,

chris.

I needed to change my video from 900x748 to 1280x1024:

I was told this:
Goto Applications>Accessories>Terminal, enter:

sudo apt-get update (your password will be asked for)
sudo apt-get upgrade
sudo apt-get install displayconfig-gtk
sudo displayconfig-gtk

This should give you a choice of video resolutions

When did they tell you this and which distro were you using ?

"Reading package lists... Done
Building dependency tree
Reading state information... Done
Package displayconfig-gtk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package displayconfig-gtk has no installation candidate"

I am sorry this did not work for you, I am new at this, I used the above info to fix my Dell 19" monitor, I must have found it here in launchpad, as I had problems with both resolution and rotation.

I am using Intrepid Ibis

I am afraid I cannot help and would suggest you close this thread by indicating it was solved and then post your question again so that it remains visible.

I found a solution with the help of some people at http://blenderartists.org/forum/showthread.php?t=148775
I used gtr to generate a modeline and Nvidia X Server Settings to generate an xorg.conf and edited the two together with information on the monitor's HorizSync and VertRefresh rate.

The resuling xorg.conf can be viewed here:-
