Created attachment 63369 --> https://bugs.freedesktop.org/attachment.cgi?id=63369 dmesg log after a prboom session
I have tried playing prboom on Fedora 17/x86_64 and noticed that the HDMI output is turned off. The DVI output is set to primary, mode switch to 640x480 is performed on the DVI output and it's switched back to 1920x1080 when exiting from prboom but HDMI output is not restored. The TV says "no signal", xrandr says this before or after a prboom session:
