Even I have the same problem at my end, the installation here is Fedora 9 sulphur,
$ /sbin/lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 290 (rev a1) driver installed for nvidia is nvidia-kmod-173.14.12-5.lvn9.src.rpm from livna repository, Uniquely it happens only when I login into KDE4 and not in gnome, and shows all same symptoms as Rocco mentioned, the lockup happens randomly ranging from 1/2 a minute to 5 minutes, and the X locks up for a while after which the lock is released and then lock can occur randomly again. I noticed the same error messages in /var/log/Xorg.0.log ................... [mi] EQ overflowing. The server is probably stuck in an infinite loop. [mi] mieqEnequeue: out-of-order valuator event; dropping. [mi] EQ overflowing. The server is probably stuck in an infinite loop.

Strangely, X doesnt lock up randomly when I use gnome rather than kde4, I tried disabling composite in xorg.conf, but X in kde4 still locks up randomly. -- 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
