Configure X server and intel drivers

Asked by Ishan A B Ambanwela

Hi,I'm quit new to Ubuntu.please help me

I had installed just ubuntu 8.10 and although my X server worked well I installed driver xf86-video-intel 2.6.0 in order to update OpenGL capability.My computer consist of intel G33 FB motherboard with on board graphics.

But now I need to install lg3d (Looking Glass Desktop Environment) which is based on X server.In session selection when Looking Glass selected it gives

"Fatal Error session exist less than 10 seconds... need to log out"

in details it says

"X server configure error.can not execute X server...".

It seems "xf86-video-intel 2.6.0" driver compiles against X server.Now I need to restore X server.
After googeling and according to Help Forum (noe i cant find !!! whi was about to restart X server)I tried in terminal

$ sudo /etc/init.d/gdm stop ______and start as well as restart.

when stop it close GUI and but when start it gives a Gray dotted screen in which mouse works but no any icons or any thing.

the other Desktop Environment GNOME works great(seems with updated Driver) I can log in and do my stuff but I'm really need to experience Looking Glass.

can anybody help me to re-install X server??? thankyou

I think the package you installed, the xf86 package is an old package. It's not an xorg driver, it is from the old xfree86 desktop. Uninstall what you installed.

sudo dpkg-reconfigure -phigh xserver-xorg

command will restore your xorg.conf file. But you need to uninstall the wrong driver and install the correct driver.

Will you please explain how to uninstall those correctly?
To install also I didn't know about very much that.I just compiled and just make install.
I have told you without special drivers I could work every thing.I did what u asked to do it gave a warning about it and made a backup also xserver but still i cant use looking glass.!

I don't know what package you installed, but you should install xserver-xorg-video-intel package for intel graphics card.

If you want to uninstall compiled package, you should cd into directory of what you installed and use:

sudo make uninstall
