Rotation at high resolutions causes black screen with ati driver
Last modified: 2009-07-14 13:28:56 EDT
Description of problem:
If I choose a high resolution (relative to the capabilities of the monitor) and
left or right rotation in the GNOME screen resolution app, the monitor goes into
power-saving mode and doesn't come back. Rotation at low resolutions such as
Version-Release number of selected component (if applicable):
F9 Preview Live CD
Steps to Reproduce:
1. In GNOME: System menu -> Preferences -> Hardware -> Screen Resolution
2. Set resolution to highest that monitor can support (2048x1536 in my case)
3. Set Rotation to "Left"
4. Click Apply
Screen goes black and monitor goes into power-saving mode

Xorg log from Radeon 9800 Pro
I forgot to mention that the same result happens on a different computer with a
Radeon 9600 Pro with the same monitor at 1920x1200.
can you try enabling EXA?
Option "AccelMethod" "EXA" in xorg.conf device section?
Tried it, same result. It happens at 1600x1200 too. Should the driver even be
attempting 90 degree rotation at resolutions where the horizontal resolution of
the mode exceeds the vertical resolution of the monitor? I would expect it (or
better yet, the RandR code) to return an error immediately.
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
