Comment 1 for bug 439464

i was update my laptop (http://www.thinkwiki.org/wiki/Category:T41) from alpha to beta-karmic. and i have the same "problem" - no desktop/background.

if i disable compiz - i have my desktop(folders/files) and also a wallpaper. dmesg say:

[ 14.809402] Linux agpgart interface v0.103
[ 15.055296] agpgart-intel 0000:00:00.0: Intel 855PM Chipset
[ 15.070235] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
[ 15.506587] shpchp: Standard Hot Plug PCI Controller Driver version: 0.4

my gcard on laptop:

    * ATI Mobility Radeon 7500 with 32MB or
    * ATI Mobility Radeon 9000 with 32MB

this chip can not display "normal" compiz settings without problems. now, without compiz the laptop works fine.
