Red Hat Bugzilla – Bug 165325
PowerBook wide screen resolutions not supported
Last modified: 2007-11-30 17:11:11 EST
This report is somewhat related to #151459
When starting s-c-display I get no option for the native resolution of my
PowerBook. Searched and found the closed upstream bug. Searched further and
found, that in the meantime a patch with modelines was added to xorg-x11.
Started to test and got a result:
Added modelines to /usr/share/rhpl/extramodes and updated the laptop-modes patch
# 1280x854 @ 60Hz (PowerBook 15in) hsync: 51.96kHz; pclk: 79.81 MHz
Modeline "1280x854" 79.81 1280 1296 1408 1536 854 855 858 866 -Hsync -Vsync
# 1440x900 @ 60Hz (PowerBook 17in) hsync: 54.7 kHz; pclk: 96.21 MHz
Modeline "1440x900" 96.21 1440 1504 1536 1760 900 903 906 912 -Hsync -Vsync
The latter one is a result of Google search:
Now the resolution was available with s-c-display, but not when running with
Finally added "1280x854" to XF86SupportedResolutions() in
/usr/lib/python2.4/site-packages/xf86config.py and got it working (1440x900 is
already listed there).
Would be nice to get this in.

This should be resolved in rawhide as of s-c-d 1.0.45-1 or later. Please test
and reopen if this is still an issue for you.
[frank@notebook ~]$ rpm -q system-config-display
Still not working.
The list now contains 1440x900, but not 1280x854.
With --reconfig I get the options 1280x800, 1152x768, 1024x768, 800x600, and
Mmm, we should be listing the resolutions advertised by the X server. What does
'xrandr -q' print?
The situation has improved.
Here's the output of 'xrandr -q' with up to date Rawhide:
SZ: Pixels Physical Refresh
*0 1280 x 854 ( 322mm x 221mm ) *60
1 640 x 350 ( 322mm x 221mm ) 60
2 640 x 400 ( 322mm x 221mm ) 60
3 720 x 400 ( 322mm x 221mm ) 60
4 640 x 480 ( 322mm x 221mm ) 60

9 1280 x 720 ( 322mm x 221mm ) 60
10 1280 x 800 ( 322mm x 221mm ) 60
11 1280 x 768 ( 322mm x 221mm ) 60
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none
The dropdown list now contains exactly these resolutions except the first one,
which is the native resolution.
Alright, added 1280x854 and a few others to pyxf86config, which might help
matters. Please try pyxf86config 0.3.33-1 and reopen if this is still an issue.
I still have this issue with system-config-display-1.0.45-1 (FC6). I seem the
same xrandr output as above..
