Red Hat Bugzilla – Bug 238721
After suspend/resume my exteternal monitor works, but internal doesn't
Last modified: 2008-08-02 19:40:35 EDT
Description of problem: My laptop goes to sleep if I'm away from the keyboard some time, which is great. When I return I resume the laptop via power button. Eveything works great after resume except my laptop screen which I can't turn on no mater what I do. When I boot up I can switch between my laptop screen and external LCD monitor but after resuming from suspend I can't do that via keyboard shortcuts Fn-F7 on my IBM R52 laptop. Version-Release number of selected component (if applicable): I have Fedora Core 6 regularly updated. How reproducible: Every time. Steps to Reproduce: 1. Leave laptop to go to sleep or put it manually to suspend mode. 2. Resume form suspend/sleep via power button 3. Try to enable laptop screen via Fn-F7 Actual results: Nothing happens when I press Fn-F7, external monitor works ok but if I need to carry laptop somewhere it is not in working state and I need to do a restart in order to power-up laptop monitor again! Expected results: Pressing Fn-F7 shuts down external monitor and turns-on laptop screen. Additional info:
Why on earth would this be a s-c-d bug? Please attach /var/log/Xorg.0.log so I can see what video hardware you're using. But note that in general, BIOS hotkey switching for video outputs is never likely to work.

sorry this is a wrong log file... ignore https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=154727 I'll send a log file from the correct laptop.
Created attachment 154733 [details] the correct log this time :) the correct log this time :) Ignore the previous log, I send it from the wrong laptop.
" But note that in general, BIOS hotkey switching for video outputs is never likely to work." That isn't the point. I want to be able to resume from suspend and continue working. Now I can't because when I resume the screen says dead. And by attaching an external monitor I can see that everything works ok after resume except the internal display on my IBM R52 laptop. If this isn't a bug for you can you point me in the right direction?
My point was merely that it can't possibly be a bug in system-config-display, as that program has nothing to do with suspend. I see you're using the i810 driver; does the intel driver work any better?
I'm confused... isn't i810 intel driver? Can you explain it a bit. Also this bug is a clone of this bug here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208650 I found a fix for suspend/resume and it is explained here: http://thinkwiki.org/wiki/Problem_with_display_remaining_black_after_resume#Solution_for_ThinkPads_with_ATI_graphic_chips_and_Intel_915.2F945GM thank you.
Fedora Core 6 is no longer supported, could you please reproduce this with the updated version of the currently supported distribution (Fedora 7, 8, or Rawhide)? If this issue turns out to still be reproducible, please let us know in this bug report. If after a month's time we have not heard back from you, we will have to close this bug as CANTFIX. Setting status to NEEDINFO, and awaiting information from the reporter. [This is mass-filed message to all open Fedora Core 6 bugs related to Xorg or Gecko. If you see any other reason, why this bug shouldn't be closed, please, comment on it here.]
This issue isn't apparent on Fedora 8.
