fglrx problem

What? I don't understand - try to explain your problem once more and better.

my graphics card is ATI Radeon 9250 ... but when I go to "Installed Hardware" i see ATI Radeon 9200 Pro ... anywayz I hit fglrxinfo in terminal and it told me i didn't have the package so i got it through "apt-get" command...then I hit fglrxinfo and a login screen appeared though i have set my system to load the graphic enviroment without asking for login info-i selected Restart instead of logging in and since then every time i start my system compiz and awn won't work...also forgot to mention that i'm running Ubuntu 7.10-any ideas ??

There's no such package as fglrxinfo, probably just fglrx? You can remove it with Synaptic or Adept or from teriminal:

  sudo apt-get remove fglrx

But that's probably unnecessary — first try and open Administration-->Screens and Graphics and select "ati " as the driver for your graphics card, after a restart try to reenable compiz through Preferences-->Appearance-->Visual Effects.

that didn't help much :/

Can you attach the contents of your /etc/X11/xorg.conf file, so we know what driver you are currently using?

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.

Looks ok, and you're using the ati driver, no sign of fglrx anywhere. What happens when you try to enable those desktop effects? Maybe /var/log/Xorg.0.log says something interesting?

Check that you're getting direct rendering, try the following command (please paste the output here too):

  glxinfo | grep -i direct\\\|opengl

Maybe the composite extension got somehow switched off, in that case you would add the following to the end of the xorg.conf (type "sudo gedit /etc/X11/xorg.conf" in a terminal to be able to make changes to it):

Section "Extensions"
        Option "Composite" "on"
EndSection

a "Desktop effects could not be enabled" message dialog is being displayed when i choose anything but "none" in Appearance --> Visual Effects...SetClientVersion: 0 9 is the bottom line that is being showed in Xorg.0.log after i try to enable the effects...after i type "glxinfo | grep -i direct\\\|opengl" in terminal it says
glxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
...so should i do the xorg.conf modification ???

i think that my problems began after i hit glxinfo in terminal...is that any helpful ??

Seems a file or a link is missing, could you please paste that in a terminal and copy the output:

  ls -l /usr/lib/libGL.so*

ls: /usr/lib/libGL.so*: No such file or directory

got a question for you ; if I uninstall all my compiz-fusion package and reload them, can you assure me that it will be working (In advance, I'm suspecting not)

packages

Ok, try reinstalling mesa then:

  sudo apt-get install libgl1-mesa-glx

Or put reinstall instead of install if it says it's already at newest version.

Reinstalling compiz-fusion won't be probably enough, you would have to reinstall alot more (some other xserver related things may be broken too, like mesa), and possibly you would have to purge(completely remove) and install to get a new configuration too.

Lets try with reinstalling mesa for now and see what the glxinfo command returns.

install command : i have the newest version
reinstall command : Not valid operation

i made it ! i did it thru synaptic package manager...i chose reinstall

now what ??

Try the glxinfo again, try to enable compiz (after a restart).

Note: the glxinfo, fglrxinfo are safe to use, won't change anything. What really caused the problem has been the installing of fglrx package.

after reboot : still the same message after trying to enable effects...
in terminal :
glxinfo | grep -i direct\\\|opengl
glxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

by the way, i want to thank you in advance for dealing with my problem...

"glxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory"

→ go to /usr/lib and make you sure you have there file libGL.so.1.2, if yes do this in terminal (Application → Accesories → Terminal)

sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1

Explication: libGL.so.1 is only symbolik link to libGL.so.1.2 and this command will created it

still no files :(
