Same problem here: used to have nice desktop effects with compiz (like wobbly windows and that sort of things), but since upgrading to natty, it's way too slow to be usable.
My graphic card is a ATI Radeon XPress 200M chipset (on an Acer Aspire 5103 WLMi CX2012 laptop computer). I tried several fixes found over the internet like disabling VSync in CCSM, set AccelMethod option to "XAA" in xorg.conf or installing the latest git version of the free radeon drivers, but nothing better for now. I know that, since ATI left behind my video card, I am not in the ideal situation, but I think this is a huge regression from Ubuntu that I can't at least use the functions that used to be working smooth. Hope we'll got a fix soon or I'll consider switching to another distro. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760814 Title: Compiz Very Slow and Choppy in Natty Classic -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
