Seems this problem has been addressed by an update in the end. I've tried to revert back to the default settings I used when the problem appeared, but I couldn't reproduce it as I could before. I've also noticed that I cannot seem to get my X much below 700 fps anymore in glxgears with a default (unmodified) xorg.conf, even with deleted driconf settings (HyperZ + SW TCL). When I started tweaking my settings there I started with 280 fps! So it seems to me something must have changed beyond my manual tweaks.
If it should matter: Since I've only had time for some rough testing, I only restarted X to test the old settings, I didn't do a full reboot. The only thing I couldn't be bothered testing was switching back to vesafb from radeonfb as the framebuffer driver. But if I'm not mistaken this should not interfere with Xorg settings, should it? Let me know if you need deeper testing on that. But since it seems that nobody else has this problem (anymore), this bug might be superfluous already. -- konsole high cpu load when maximized https://bugs.launchpad.net/bugs/296835 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
