Completely purged all fglrx and reinstalled/reconfigured core xorg components and the radeon driver as per the Ubuntu Wiki instructions: sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists) sudo apt-get remove --purge fglrx* sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon sudo apt-get install xserver-xorg-video-ati sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg
General 2D performance is OK. In particular, regular GTK (GNOME) and Qt (KDE) apps are responsive. CPU usage is normal (was always normal with -radeon, performance was the problem) The most severely affected programs for me were the pure java ones (Netbeans being a particular pain point: Java 2D?) I am using the Sun Java 1.6 JVM, installed from the Ubuntu repos. I will code in Netbeans for a while to get a feel for the speed/responsiveness of the system with these drivers. In all likelihood, this is not a valid xorg bug. But I will leave it for someone with more xorg knowledge and experience to close. -- High Xorg CPU usage (95-99%): Karmic x86-64, fglrx, ATI Mobility Radeon HD 2600 https://bugs.launchpad.net/bugs/440448 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
