Red Hat Bugzilla – Bug 613188
RV100 Dual screen display corruption - KMS disabled automatically.
Last modified: 2018-04-11 06:30:38 EDT
Description of problem:
When running with dual screens enabled, the display contains artifacts. The screen is just about readable. New dialogs require a 'wipe' to display properly. The taskbar is always corrupted.
Single screen configuration works fine. During boot, the lo-res scrollbar is displayed, so KMS is being disabled automatically.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot system as normal. KMS is disabled automatically.
2. Login to system (First sign of corruption is after entry of username)
Display is corrupted.
Display should not be corrupt.

My laptop displays this identical issue: When on a single screen, no corruption is observed; when dual-screen there is significant graphic corruption. I've attached my own copies of the requested logs. I'm using the same version of xorg-x11-drv-ati (6.13.0-1.fc13.i686).
Feel free to request additional information as needed.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. 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bug reports from releases that are no longer maintained.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 '13'.
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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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no longer maintained, which means that it will not receive any further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.
