Created attachment 12174 [details] [review] x log Created attachment 12175 [details] [review] xorg.conf Anyone? This is killing my eyes. Just installed version 6.7.196-2.fc8 but no change. Any way to force 85Hz in xorg.conf? Although I think the problem is that X *thinks* it is driving the display at 85Hz, but it really isn't. can you attach the output of xrandr? Does it help if you switch to another mode and back? xrandr --output VGA-0 --mode 1024x768 xrandr --output VGA-0 --mode 1600x1200 --rate 85 xrandr --output VGA-0 --mode 1600x1200 --rate 75 Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 1600 x 1200
VGA-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 352mm x 264mm
1600x1200 85.0*+ 75.0
1024x768 85.0 75.1
1280x1024 84.8 75.0
1152x864 75.0
800x600 84.9 75.0
640x480 84.6 75.0 60.0
720x400 70.1
LVDS disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)
Switching to 1024x768 drives the monitor at 117.8kHz/146Hz.
Switching to 1600x1200x75 drives it at 74.5kHz/59Hz.
85 73.9kHz/59Hz.
So it doesn't appear to be twiddling the registers properly.
does VGA work properly when the lid is open and LVDS is active? Created attachment 12939 [details]
x log with lid up
With the laptop out of the dock and the lid up, it drives the external monitor fine. Mode is 106.8kHz/85Hz as reported by the monitor.

I think bug 12913 and bug 13533 may be related. It seems pll 0 has issues that may be related to bios init. *** Bug 13590 has been marked as a duplicate of this bug. *** *** Bug 13533 has been marked as a duplicate of this bug. *** should be fixed with commit: f3d2ec3a5ae61215c792018320158750e7aa937c Works for me. Thanks! After commit f3d2ec3a5ae61215c792018320158750e7aa937c, the display in my laptop's internal panel is heavily distorted. This also resolved my issue. Dual-head is working fine now! Seems fixed, closing the bug, reopen (and update buginfo) if you still have issue with lastest xf86-video-ati. |
