Description of problem:
When running prboom, the monitor is changed from my defined SVGA resolution of 1280x1024 to probably a VGA mode. The game starts to play, but the screen goes black and the monitor goes into sleep mode due to lack of video signal.
Version-Release number of selected component (if applicable):
Every time prboom is run since upgrading to fc13
Steps to Reproduce:
I think it's a graphics card driver or monitor or Xorg configuration problem. /var/log/Xorg.0.log would be more informative.
Do you have CRT or LCD? Do you have /etc/X11/xorg.conf file with listed given graphics mode (Doom used 320x200x8b usually) and with corresponding modeline?

That's the place. Nouveau does not disjunct monitor and embedded modes probably.

And this the resize to correct resolution that fails for unknown reason.
However I cannot see place where prboom switches the mode. This is what I get:
$ grep resize /var/log/Xorg.0.log
[ 70.093] resize called 1680 1050
[ 1301.850] resize called 640 480
[ 1592.013] resize called 1680 1050
The fist one is Xorg start, the second one is prboom start, the third is prboom exit. The prboom resolution is define in ~/.prboom/prboom.cfg. (However if prboom is compiled in special manner, the setting is ignored. This does not seem to be case of Fedora.)
You can try to select better resolution in the file. (Be ware the bitmaps are just scaled. They are not available in other resolution than original 320×200.)
Or you can check the screen mode resolution switch by xrandr tool. You can try to (re)define the small resolution by xrandr tool (however it's quite nasty process, search for some how-tos).
Or you can try to fix the Xorg configuration by manual Modelines definitions.
In the old pre-randr days I specified HSync and VSync frequencies in Xorg.conf and then I used `xvidtune' to tune the picture on CRT. Then I copied the tuned Modelines (`Show' button in xvidtune) into Xorg.conf. However after Randr-1.2 emerge, the xvidtune stopped to work. I'm not aware of current practice.
I can publish here my Xorg.conf used on a CRT machine if you wish to inspire how to modify the Xorg configuration file.
Petr, thank you. It seems that the Nouveau driver is not completely compatible with my chipset. After fooling with it a while and then ultimately moving to the latest Nvidia driver, this problem and some other graphic peculiarities have vanished. Chipset is GeForce 6100 n405.
I'm glad you found a solution. I'm moving this issue to nouveau driver component. Feel free to close this report if you do not have any comments to nouveau maintainers.
Final comment: The most notable video peculiarity is the use of a very large character format (virtually illegible) with the console. For X, this was overcome by choosing an extremely large point font size. I could not force the console to a different resolution, e.g. 80x25 characters.
