10.6 crash on notebook HD4200 with compositing
I have a problem with 10.6 (and previously 10.5) crashing, and I've been stuck with 10.4. I heard about the new 2D accel and stuff and was hoping to get the newest drivers working.
I have a HP notebook with an integrated Radeon HD4200. Catalyst 10.4 successfully ran for me with kernels 2.6.32-bpo.5-amd4 and 2.6.30-bpo.2-amd4 on Debian Lenny with the default X.Org 1.7. I use GNOME/Metacity with compositing enabled and Cairo-Dock with no issues (aside from the occasional artifact).
When I installed 10.6, I can log in via GDM. After that, the GNOME panel loads, and it appears that Metacity starts, XOrg crashes. If I put "Composite" "Disable" in xorg.conf, it will start (albeit Cairo-Dock crashes and refuses to run unless I use -c and then its just ugly). I have even played using OpenGLOverlay and VideoOverlay with the same result.
I have uninstalled 10.4 before installing 10.6 by running /usr/share/fglrx-uninstall.sh and deleting any files in /usr/lib with fglrx (if any) and deleting /etc/ati. I don't believe I have any files left over from an older version.
Any other suggestions?
