Package: gdm Version: 2.20.4-1 Severity: normal
The simplest way to reproduce this bug on my hardware is to create the following shell script (killdisplay.sh): #!/bin/sh pkill -u kevmitch invoke-rc.d gdm stop Where "kevmitch" should be replaced by the user logged in graphically via gdm. su to root from that users display and run # nohup ./killdisplay.sh Gdm will indeed stop, but you won't find any framebuffer output, i.e., you can't log on to the console anymore. Ctrl-Alt-F1, etc don't do anything. However since I happen to have an ACPI button mapped to /etc/init.d/gdm start, I was able to restart the daemon which does start X again and runs "normally". The frame buffer is still dead however and will remain so until reboot no matter what I do. This does not happen if I modify the above script to sleep for 1 second in between killing the procs and stopping gdm: #!/bin/sh pkill -u kevmitch sleep 1 invoke-rc.d gdm stop This dumps you out on a functional framebuffer console as expected and desired, but gives the distubing kernel message [ 150.445462] gdm[4927]: segfault at 0000000800871ff8 rip 0000003108c5692f rsp 00007fff8a9dbac0 error Increasing the sleep interval to 2 prevents the above segfault from occuring.
