Broken Display After Resume On Dell Inspiron 640m
Last modified: 2018-04-11 06:38:34 EDT
After resuming from suspend the laptop display lights up, but still remains dark
or occasionally warped in strange ways. The issue can be worked around sometimes
but switching consoles with Ctrl + Alt + F1, then back with Alt + F7. This tends
to work for the first one or two suspends, after that the screen doesn't even
light up and I cannot get it back.
Have checked for quirks using the script at this page:

Suspend/resume worked on this hardware very well with Fedora Core 6 but has been
broken ever since.
Smolt profile available here:
Will attach Xorg configuration after creating the ticket.
I've attempted to fix with the following modules listed in
SUSPEND_MODULES="iwl3945 b44 firewire_core firewire_ohci"
But again with no luck.
Also tried: 'pm-suspend --quirk-vbe-post' but this seems to give me the
completely black and unlit display after resuming.
Will be happy to offer any additional info, this is everything I could think of

Could we get /var/log/Xorg.0.log as well, please?

/var/log/Xorg.0.log immediately after succesful workaround posted earlier.
workaround? Sorry, I don't see any workaround mentioned in the above comments.
When the display is lit up but blank after resume, Ctrl + Alt + F1 followed by
Alt + F7 gets me back to my X session.
Also I should note that the text consoles F1 - F6 all never return after
suspending/resuming the first time. Switching to them just gives a blank screen.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. 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bug reports from releases that are no longer maintained.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 '8'.
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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
