Display Resolution problem

Asked by Mohamed Kikia

I did a complete install of Ubuntu 9.04 on my Fujitsu Siemens Laptop. I cannot set the display resolution better than 800 x 600. Under "Display Preferences" the drop down box only lists 800x600, 720x576, 720x540, 720x480 and 640x480. It also lists the monitor as "UNKNOWN". I did not have any problems with Ubuntu 8.10. Any one have a solution?

Thanks in advance

I've 8.04 and I'm not sure, if my hint can help. You've to try.

1: Copy the file /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak
2: In a Terminal enter sudo gedit /etc/X11/xorg.conf
3: Have a look at the screen section (the sub section is important)

Section "Screen"
 Identifier "Default Screen"
 Device "nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]"
 Monitor "Generic Monitor"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800"
        EndSubSection
EndSection

4: Save the file
5: Restart the system

The update of the file shouldn't take more than 15 minutes – otherwise you're going to loose the root privileges and you wouldn't be able to save it.

Hope it helps.
Peter

Hi Peter

Thanks for the response. I have not done any changes as yet. I typed in sudo gedit /etc/X11/xorg.conf. This is what is under Monitor:

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 SubSection "Display"
  Virtual 800 600
 EndSubSection
EndSection

Section "Device"
 Identifier "Configured Video Device"
 Driver "vesa"
EndSection

How do I copy the file /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak?

Please excuse my ignorance. I am a little green at this but willing to listen and learn!

To copy (backup) the file, just issue the command below:

sudo cp /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak

Pardon. My mistake, that should be of Peter's suggestion.

Thanks for all the help. I changed the xorg.conf file and ended up not being able to read the screen at all. I eventually re-loaded Ubuntu and the display is now fine. I have another problem - usb problem which I will list under a new heading. Once again thank you all, at least I learnt something from this!
