Not sure what to do.

I get:
xserver-xorg postinst warning: overwriting possibly-customised configuration
file; backup in /etc/X11/xorg.conf.20090621225211

I cant get passed the first step! Need help…

Nobody has talked about the Virtual tag, but it seems pretty logical that I had to change this as my maximum resolution was 1278 768.
Then I have just changes the Display section to this:

SubSection “Display”
Virtual 1280 800
Modes “1280×800@75″ “1024×768@75″ “1024×768@70″ “832×624@75″ “1024×768@60″ “800×600@60″ “1280×960@60″ “800×600@75″ “800×600@72″ “800×600@56″ “640×480@75″ “640×480@72″ “640×480@60″
EndSubSection

After a restart I was able to change the display resolution. Thank you very much.

Im super new too linux.

Thanks for your help.

Restart and at login screen, run session as Failsafe Terminal and at the terminal prompt, type ” gnome-control-center ” and change the screen resolution from there. Restart Ubuntu 8.04 and voila.

Hope this helps.

$ sudo apt-get install nvidia-settings
$ nvidia-settings

This works well on ubuntu 8.04.

I got full display working on my 17″ iMac under Parallels build 3188 after installing Ubuntu 8.04. After a bit of research, I came upon the xorg.conf I’ll include at the end of this email. Still no joy, until I added custom resolutions in the Parallels preferences of 1440×900. Then, bingo.

Hope this helps…
