Which version of Ubuntu, 8.10? If you installed from a live CD, does the live CD work OK? Does the CD pass the self-test?

you probably will need to remove compiz or try to log in recovery and disable compiz/desktop effects

The version ubuntu is 8.10. I have tried by live cd and when i got the desktop screen and move the mouse i get a black screen.
Thanks abn91c, but what i need to do to disable compiz/desktop effects ?

Thanks

ctr+alt+f1 to get to the prompt, then sudo apt-get remove compiz followed by sudo apt-get remove compiz-core, then reboot

Have you tried installing from the ALTERNATE (text based) version of Ubuntu ?

[jjmmjjmm]

Thanks. No, i go try, (http://www.ubuntu.com/getubuntu/down...rors#alternate). If dont work go try with others distros like: opensuse, mint, fedora or mandriva. Any sugestion ?

Thanks

Good luck with the alternate install try. abn91c's advice about removing compiz is worthwhile too; turning that off has helped me when there were issues with binary nvidia drivers on some PC's.

If Ubuntu isn't working out for you due to hardware issues, maybe try Fedora 10. I've been impressed with its hardware recognition, particularly for wifi chipsets.

Same problem here. I removed compiz but the problem isn't solved.
I think vga ati9700 64mb is the source of the problem but my system boots in Windows XP as usual.

There are at least 3 X driver choices when dealing with ATI chips: vesa, the ati open source family, and the proprietary fglrx. If you are getting blank or black screen, you need a different one. Assuming that you can boot in "recovery mode" (single user), you can edit /etc/X11/xorg.conf with vim or nano and change the driver. Find the section at the bottom that looks like

Section "Device"
	Identifier	"Configured Video Device"
	Driver	"fglrx"
EndSection

and try a different driver, such as vesa or radeon. You won't have fglrx unless the restricted driver is installed and active, but that may well have happened by default during the initial install.
