Exclamation Cannot get pass login screen


Hi,
I have Fedora 8 Gnome version on my PC.
I ran updates using yumm and installed compiz fusion.
After rebooting I m getting a very different login GUI.
When trying to log in as root I can see desktop background image for about 3 sec and then it throws me back to the same Login GUI.
If I try to get to text console with Ctrl_Alt F2 I get black screen and PC hangs.

Please help

Try ctrl-alt-F3 instead of F2: tty0 and tty1 are both used by the boot process. tty0 is the system boot process (and you can often see error messages on it), and tty1 is used for the X-server startup.

What the blank screen on ctrl-alt-F2 is telling you is that your video card or setup is either not compatible with compriz or not correctly configured.

Thanks for the reply.
I ve tried your suggestion but I get the same black screen.
I ve tried different key combinations but with no luck.
The only key that works is Ctrl Alt F7 that takes me back to the login screen.

Is there any way I could uninstall compiz considering system current condition?

Thank you

When the GRUB logon screen (where you select the OS to boot) is displayed press the Escape key. That should show you the GRUB editor screen. Select the boot line for Fedora and press "e" to edit the boot commands. Move the cursor (with the arrow keys) to the "kernel" line and press "e" again to edit that line. Type " 3" to add a space and the number 3 at the end of the line and press return. Then press "b" to boot into "run level 3," a terminal-only, single-user mode.

Note: The GRUB editor only changes the data in RAM -- the actual boot file is not changed.

If that works, the system should boot and you should see a "Login:" prompt. Log in as "root," and do an ifup to start your network. Then a yum erase compiz should remove the compriz stuff. (I believe that yum needs the network access even to remove an RPM.)

Alternatively, you could see if there's a backup of xorg.conf in /etc/X11 that you could use to replace your current one. Normally when a RPM modifies xorg.conf the working one is renamed xorg.conf.rpmsave or something like that.

Oh, if you get your network working, do a yum install mc to install the "Midnight Commander." Then the mc command will start a pseudo window that you can use to find, edit, move, copy and rename files using the arrow and function keys. It's quite handy when the GUI isn't working.
