Description Philippe Moreau 2004-10-26 13:54:32 UTC
Description of problem:

When the option rotate CW is enabled and two modes ("1280x1024" and
"640x480") are configured in the xorg.conf file, switching from
1280x1024 to 640x480 works fine, but switching from 640x480 to
1280x1024 never occurs.

When the Rotate Option is removed, switching occurs as expected.


Version-Release number of selected component (if applicable):
xorg-x11-6.7.0-9

How reproducible:
Always

Steps to Reproduce:
1. Enable the option Rotate CW in xorg.conf
  (Option "Rotate" "CW" in section "Device" of the video driver "mga")
2. Configure the modes 1280x1024 and 640x480 in xorg.conf
  (Modes    "1280x1024" "640x480" in the SubSection "Display")
3. Switch resolutions: xvidtune -show; xvidtune -next; xvidtune -show;
xvidtune -next; xvidtune -show

Comment 2 Mike A. Harris 2004-11-29 21:11:57 UTC
The RandR extension is incompatible with the "Rotate" option
which some drivers implement.  Additionally, the "Rotate" option 
is not fully tested or supported in most drivers, and should be
considered experimental.

Please report this issue directly to X.Org in the X.Org bugzilla
located at http://bugs.freedesktop.org against the "xorg" component.

we will track this issue upstream and review any fixes that
become available for consideration in future updates.


Comment 3 Mike A. Harris 2005-04-11 19:14:06 UTC
