Comment 33 for bug 124519

Using a Thinkpad T41 with Radeon 9000 (r250) @1400x1050 on Ubuntu 7.10 (Gutsy Gibbon):

I also have felt the love from compiz now that I modified xorg.conf Thanks to the folks here I reduced default depth from 24 to 16 and miracles of miracles, it works.

Because of the bug in the compiz wrapper for ati, I have to run it as ">SKIP_CHECKS=yes compiz" to get it to work. But after that works great, no crashes, resume after suspend ok....

Here is the relevant section from xorg.conf

 Section "Device"
        Identifier "Radeon 9000"
        Driver "ati"
        BusID "PCI:1:0:0"
        Option "XAANoOffscreenPixmaps"

# Virtual 1600 1200 # seems to work without this hack
                Modes "1400x1050"
        EndSubSection
EndSection

Section "ServerLayout"
        Option "AIGLX" "true"
        Identifier "Default Layout"
