Red Hat Bugzilla – Bug 592764
black screen with KMS
Last modified: 2011-06-27 12:24:42 EDT
Description of problem:
When KMS is enalbed, using vesa
driver results in a black screen.
The PC is not locked up, you can
still Ctrl-Alt-BkSp then Ctrl-Alt-Del
(when X is terminated, the console is
not restored, so you have to reboot)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable KMS
2. Enable vesa in xorg.conf
Black screen. Monitor complains about
the out-of-range freq and shuts down.
Umm, well, I guess the vesa driver
can't work with KMS by definition,
so perhaps the adequate error message
would just do. It may suggest using
fbdev instead, or it can fall back to
fbdev, or something like that...
Oh, forgot to specify the card:
05:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870
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bug reports from releases that are no longer maintained.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no longer maintained, which means that it will not receive any further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.
