Title: system locks/freezes up after some time idle Status in “fglrx-installer” package in Ubuntu: New Bug description: After leaving the computer connected to an external monitor and unattended a few minutes, the system locks up. The only recourse is to reboot with Alt+SysRq+B. Switching terminals or disconneting the external monitor does not work. syslog/dmesg don't contain any interesting event before freezing up. However, Xorg.log says: [ 23368.997] [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
