How do I change the display settings manually of Ubuntu 8.04.01?

IdahoSilverSage · 01-24-2009, 03:43 PM

I am unable to login and to see the login screen properly after upgrading to Ubuntu 8.04.01 from an older version.

It is loaded on an HP Pavilion 8766C box with a HP Pavilion M90 monitor.

I did the upgrade several months ago and haven't done anything with it since then. I have searched for solutions/guidance on how to change the settings manually, but can't seem to put my hands on anything specific so far on how to change the settings to generic display.

Thanks in advance on any suggestions or help you can provide.

Greg

if you agree you are using onboard video
http://h10025.www1.hp.com/ewfrf/wc/d...uct=59903#N956

then try booting up to runlevel 3 and manually editting your
/etc/X11/xorg.conf to a setting in the above link

otherwise pls post what kind of video you have please

I finally found the xorg.conf file after realizing it was in:

etc/X11 rather then etc/x11

I have found the line Virtual above the Modes and it shows 2048 1536 and the Modes, which lists the whole list of the various resolutions.

I #Modes and created a new line Modes with "1280x1024", leaving the Virtual 2048 1536 with no success; still displaying incorrectly with no option to login. I left the Modes as is and changed the Virtual to 1280 1024 and ended up with several, blurry, vertical sign in screens.

I am setting the xorg.conf file back to the way I originally found it and will be doing some more research. Thanks to those who provided suggestions thus far. :-)

I decided to try one other thing so using nano etc/X11/xorg.conf I took the Virtual out of the load by #Virtual and the login screen is displaying correctly now.

Edit your /etc/X11/xorg.conf (don't forget to backup it before) and add/change in the Device section:

Code:

Driver "vesa"

remove/comment any line that contains Modeline and look for you Videocard subsetion and set the default resolutions for something like 1024x768, 800x600 (or if you display is wide something like 1024x960 or 1024x600)

Code:

SubSection "Display"
Depth 24 # you change to 16, but normaly 24 will work
Modes "1024x768" "800x600" "640x480"
