I had a similar issue after upgrading from Gutsy to Hardy. Everything rendered terribly slow, and although the "Enabled" checkbox for the ATI driver was checked off, it said "Not In Use" next to it. I looked at an unofficial wiki for ATI driver support on Ubuntu and here's what I suggest doing:
Check if you have the package "xserver-glx" installed. If so, Ubuntu may be using the GLX driver even though you told it to use the ATI driver. To double-check if that's what's really happening, type "glxinfo" (you may want to use " | less" afterwards since sometimes the output can be lengthy). If you don't see any "ATI" vender strings there, but see vendor strings with "MESA" in it, your Ubuntu is using the wrong driver. I personally was able to remedy this by simply uninstalling xserver-glx, logging out, rebooting X Server and then logging back in. Hope this helps! -- Hardy: Graphics driver "not in use" https://bugs.launchpad.net/bugs/224130 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
