View Full Version : [ubuntu] Need help reinstalling desktop environment

March 31st, 2009, 01:07 PM
I have a dual boot with WinXP and what used to Kubuntu. Because my laptop is getting old and KDE4 is kind of heavy I decided to migrate to ubuntu 8.10 and chose to do a fresh install over my kubuntu partiton.

To keep a long story short: I ran into some problems because my CDROM drive is apparently not working very well. I can boot to WinXP without problem, when I boot to Ubuntu, screen resolution is 800x600, and when I shutdown the laptop, the screen just goes black and becomes non-responsive, I have to manually shutdown. If I boot from live CD everything seems to work fine and I have my native resolution (1280x800), but often the CD hangs when trying to boot... I checked the CD, it's fine, I even used it to install ubuntu on my old PC without problems.

I would like to reinstall the desktop environment, but want to avoid reinstalling ubuntu from CD because of previous issues. How can I achieve this from commandline? What exactly do I need to reinstall, Gnome? X11? something else?

Please of you reply can you provide the commands I should give? Thanks a lot in advance...

Maybe you could try the 9.04 beta?

Upgrading from Ubuntu 8.10

To upgrade from Ubuntu 8.10, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '9.04' is available. Click Upgrade and follow the on-screen instructions.

Thanks for the reply, I will give it a shot. I don't need to add repositories to enable the upgrade to 9.04beta?

Ok, I upgraded successfully to 9.04beta, which got rid of the shutdown problem. My resolution is still at 800x600 though. I tried editing my /etc/X11/xorg.conf file, but so far it either doesn't do anything or it results in a nonfunctional file.

Any ideas? I have a compaq presario r3000, the screen is a widescreen with native resolution 1280x800, according to the label on the laptop my graphics card is ATI mobility radeon 9000 IGP

Any help would be greatly appreciated...
