I can confirm that this bug affects the OS ati driver as well: I use kububtu/kwin and "ati" driver. Desktop effects are on. There is no xinerama section in my xorg.conf. xorg is freezing at random times - I could not detect any pattern yet.
When logging in with ssh from my other machine Xorg process is at nearly 100% CPU, I can kill it only with signal 9, then X starts up fresh to the login screen. Xorg.log spits out a lot of these messages: [mi] mieqEnequeue: out-of-order valuator event; dropping. [mi] EQ overflowing. The server is probably stuck in an infinite loop. -- X Lockup in Intrepid (infinite loop) https://bugs.launchpad.net/bugs/259808 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
