DPMS support not working out-of-the-box
Last modified: 2007-11-30 17:11:43 EST
Description of problem:
DPMS was not turned on ever since I installed fc6test2. I'm filing this against
test3 since after upgrading everything and running system-config-display (which
depends on pyxf86config) DPMS is still not enabled.
Generating the xorg.conf file manually using Xorg -configure fixes the problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install fc6test2 (or test3)
2. xset dpms force off
Screen does not turn off, xset reports that dpms extension not available
Screen turns off

This xorg.conf has working DPMS support
Delete the Module section from the pyxf86config-generated config file. This is
a bug in rhpxl 0.29-1 and earlier.
