Description of problem: Followed: https://fedoraproject.org/wiki/QA:Testcase_intelvideo_multihead When I boot my Thinkpad T500 with external display connected via VGA, in plymouth I have image on both screens. But as soon as GDM starts up, the VGA display is disabled (displays "no signal" message) and only laptop display is used. Version-Release number of selected component (if applicable): gdm-2.31.90-7.fc14.x86_64 xorg-x11-drv-intel-2.12.0-6.fc14.x86_64 Smolt: http://www.smolts.org/client/show/pub_bdc5d4b2-09d8-4e88-a38d-e85817c3bc84 How reproducible: always

When I use gnome-display-properties, I can enable the VGA display and it works just fine. But after clean boot it is again disabled.
... and "Make Default" button doesn't work?
(In reply to comment #3) > ... and "Make Default" button doesn't work? I don't know, I can test it if required. But this bug is reported against the default behavior (that is 'display powered off'), which breaks this test case requirement: "4. Verify that the graphical environment starts correctly and is spanned across all connected displays (Fedora 12 and later) or shows the same output on all displays (Fedora 11 and earlier) "
(In reply to comment #2) > But after clean boot it is again disabled. Sure, I am not trying to make this NOTABUG, just tryng to get a clarification on this. And of course I would need standard logs set: Please add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log) * output of the dmesg command, and * system log (/var/log/messages) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance.

There is a short time when starting X server when I see (halves of) mouse cursor on both monitors. But as soon as GDM is about to show, the external monitor is disabled. After login it is enabled again.
was this a clean test installation, or have you used the system before? You may perhaps have stored a config with the external monitor disabled, and forgotten about it... -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers

GDM/GNOME seem to store their configuration of the monitor layout somewhere other than xorg.conf. I haven't figured out where, yet.
I have confirmed this problem even with F14 Beta Live. 1. Plymouth runs on both monitors. 2. When GDM starts, external display is disabled. 3. After logging in, external display is enabled. 4. You can use gnome-display-properties to enable external monitor. The setting is remembered. 5. After logging out into GDM, external display is disabled again. 6. After logging in, external display is enabled. (remembered from step 4).
This should be probably reassigned to GDM component, what do you think?
Looks similar to bug 595644, not the same though. Anyway, passing to ajax, and he wants to close it as duplicate of bug 595644 (or anything else), his call.
Maybe this is the same issue as bug 623824 comment 15.
(In reply to comment #16) > Maybe this is the same issue as bug 623824 comment 15. Oh, very nice. I enabled /apps/gnome_settings_daemon/xrandr/turn_on_external_monitors_at_startup as root as used "Set as Default". After that external monitor is truly enabled in GDM, showing in cloned mode. Re-assigning to gnome-settings-daemon.
