Created attachment 359030 [details] Xorg log from a resumed session where the external display is not detected Description of problem: Following a suspend/resume cycle, xrandr and the configuration of external displays seems to be in a state of disarray. This issue best provoked by suspending with the external display attached, disconnecting it, and then resuming. Upon resume, the notebook's flat-panel re-activates, but its viewport is as it was before suspend; the unlock box is where the erstwhile external display should be and so one is presented with a blank screen. Typing blind unlocks the screen, but since it was configured as secondary the GNOME Panel is nowhere to be seen. Pressing the "external monitor" hotkey seems to force a rethink, and the notebook panel takes over again. Now, following this, external displays are no longer detected: [james@rhapsody ~]$ xrandr Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm 1280x800 60.0*+ despite a monitor being attached to VGA1 and switched on. Pressing the "external monitor" hotkey doesn't help. Normal service does not resume until reboot. Version-Release number of selected component (if applicable): kernel-2.6.30.5-32.jhe.fc11.x86_64 xorg-x11-drv-intel-2.7.0-7.fc11.x86_64 How reproducible: Always.

Curiously, when shutting down a session broken as detailed above, the external monitor did activate and show the plymouth shutdown logo...
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '11'. 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 11'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 11 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
