Resolution cannot be increased
Last modified: 2009-11-23 14:26:42 EST
Description of problem:
wrong resolution of my laptop screen
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.start the computer
maximum available resolution is 1024x768
it should be 1200x800
well I issued xrandr -q on the same machine in F10 and F11:
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 1280 x 1280
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
331mm x 207mm
TV disconnected (normal left inverted right x axis y axis)
and in F11:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
VGA1 disconnected (normal left inverted right x axis y axis)
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y
axis) 330mm x 210mm
1280x800 60.0 +
TV1 disconnected 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
In gnome-display-properties 1280x800 is not available in F11, in F10 is o.k.
Running intel driver
You can still do xrandr --output LVDS --mode 1280x800 to get it into native mode right? The bug is that we detect a non-existent TV out and X picks the highest mode that both outputs (the TV and your LVDS (laptop panel)) can handle.
If you un-mirror screens (there's a checkbox in the dialog to do that), you should be able to select the LVDS and increase the resolution for that to 1280x800.
I issued xrandr --output LVDS --mode 1280x800 and un-mirrored screens. Now resolution is correct but system cannot be used as bars with menus are on the far right of the screen and cannot be repositioned, so I cannot see menus and operate on them.How do I recover from it?? I cannot see a terminal window.
I think that I have to switch to text mode, and then??
I am seeing this behaviors since KMS is enabled in rawhide.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
