I can confirm that this has been happening on Ubuntu 12.04 as of 12/17/2012.
This usually occurs using compiz when the monitors go into ACPI power save mode. This occurs using both the open source ATI driver, and fglrx. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/195051 Title: [RV350 9600] [Needs quirk] X freezes in drmCommandWrite() when Compiz is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/195051/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
