I can confirm this bug. The same things happened today on a brand new computer with an ASUS P7H55-M PRO motherboard fitted with an Intel i3-530 CPU, both in the Live CD environment and after a successful installation (had to use the alternate installer).
After a bit of googling I found an acceptable workaround though. By chaning the last line in /etc/xdg/compiz/compiz-manager to COMPIZ_NAME="metacity" (effectively turning desktop effects off) everything seems to work just fine. I can't tell for sure if this workaround will work in the long run as I just installed the system but it's been working flawlessly for about an hour now compared to the 5-10 seconds it did before. Could someone enlighten me/us as to whether this is a bug in the driver, in Compiz or in the kernel? For the record I'm running a stock Karmic kernel (2.6.31-19-generic). -- entire desktop environment locks up in 9.10, i3-530 proc, built-in graphics https://bugs.launchpad.net/bugs/516909 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
