Description David Timms 2008-03-30 07:56:23 EDT
Description of problem:
the rhgb is shown OK. as gdm is displayed, the backlight gets turned off.

Version-Release number of selected component (if applicable):
F9Beta gnome live cd iso.

How reproducible:
3x boot ups have occurred identically.

Steps to Reproduce:
1. download live cd
2. live-cd-usb 
3. boot usb
4. machine boots {10 secs}
5. text boot up process scrolls down screen
6. rhgb: fedora-show details... finishes
Actual results:
looks like machine powered off. power led and battery charge leds are still lit.
on closer inspection and in the right light, backlight is off. 22:50

Expected results:
backlight on. then you could easily choose the login button.

Additional info:
notebook pc: hp compaq nx6320. issue not present with F8 up2date 2008-03-28.

waiting for the screensaver to start (since the session automatically logs in);
then mouse/kb to exit makes the backlight turn on.

can also trick the machine into backlight into turning on by _turning off_ the
notebook power supply.

Noticed some gdm debug bits so including this incase it is relevant
The machine is also offering to send kernel oopses to upstream, I let it do

Noticed some failures at setting modes:

(II) intel(0): EDID vendor "LPL", prod id 47872
(EE) intel(0): Mode 1280x1024 does not fit virtual size 1024x1024 - internal
(II) intel(0): fbc disabled on plane a
However, without the time in there I don't know if that was occurring as gdm

Can you try with the new rawhide image that went up on Friday?  This should be
fixed with it.
Comment 4 David Timms 2008-03-31 05:17:18 EDT
I retested with the torrent -
The backlight now stays on during gdm display and login, and into the user session.
Screensaver dimmed screen after 11 minutes and mouse movement woke the screen OK.
