Thanks Raphael It's weird. I tried a modified xorg.conf with just the "AccelMethod" "XAA" and that ran as crappily as before (20-50% cpu time for X).
I decided trying to re-install vanilla Jaunty (quite radical solution, but I figured I might have some crap installed I didn't remember and wanted to exclude that). The only alteration to xorg I have right now is: Driver "radeon" I can live without compositing, but it still bugs the hell out of me, what the high cpu usage of X was. Here's hoping that someday compositing on R300/R350 chipsets will work again sometime, I know it did under intrepid. -- [RV350] system freeze randomly, need hard reset https://bugs.launchpad.net/bugs/349229 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
