Red Hat Bugzilla – Bug 236372
intel driver doesn't power off display, i810 driver does
Last modified: 2007-11-30 17:12:02 EST
Description of problem:
I have an Aopen MiniPC 915-B and with an external LCD monitor connected over
DVI. The machine is basically a laptop with no display or keyboard. However,
when I use the "intel" driver the display is never powered off by
gnome-power-manager. Keeping everything else the same and switching to the i810
driver in xorg.conf the display is powered off (sleep state, orange light) at
the correct interval specified in g-p-m
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Setup xorg.conf with intel driver
2. wait 30 mins (interval specified in g-p-m)
3. display will not go off
4. Change xorg.conf to use i810 driver
5. Logout, login
6. Wait 30 mins, display will go to sleep
Display stays powered up, but blank
monitor should go to sleep, lower power mode
