Red Hat Bugzilla – Bug 829516
No brightness in GDM login screen
Last modified: 2013-08-01 06:12:06 EDT
Description of problem:
Version-Release number of selected component (if applicable):
I have an HP Pavilian dm4-1265dx Laptop with Fedora 17 and Kernel-3.3.4-5.fc17.x86_64. When the lowest brightness possible is set, you cannot see the screen at all. This is not a problem, but the problem happens when I first start up the computer. The GDM brightness is set to the lowest possible setting and so you cannot see anything when logging in. I have to just press enter and blindly type in my password. Logging out of gnome and going back to the GDM screen does not have this problem. In that case, it is set to max, which is fine. I would like this fixed since it makes switching from gnome to lxde tedious. I am new at this, so please let me know what you would need to fix. Thanks.
Steps to Reproduce:
1. Turn on computer
3. Try see login screen
Cannot see login screen
Ability to see login screen
Problem has been persistent since Fedora 15. I reported the same bug before, but was told that it was the wrong component.
This isn't a gdm bug, although it would be nice if gdm could handle the brightness keys somehow. If the backlight is off during the booting process (i.e. you can't see the plymouth progress screen), then you're probably seeing this bug:
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 '17'.
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 17'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 17 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, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
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.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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.
