Description of problem: Just tried to boot from a live usb iso of Fedora 15 alpha. I've a second monitor (VGA) attached: the boot process arrives at the GDM login. Clicking on login (live system user) gives the screen blank for a second and then it shows again the gdm login screen (it gives the impression that the gdm is restarted after a X11 crash. I don't know how to access further information because I don't know with which user log-in from a command line, so I've filed the bug against the X11-server. Tried the same boot process without second monitor attached: it's possible to login and use the system BUT: if the second monitor is reattached the gdm login is represented and the behaviour is as above. The behaviour seems somewhat related to #680037 Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Attach second monitor (VGA) and try to boot the machine or attach a second monitor at "run-time". 2. 3. Actual results: Expected results: Additional info: Smolt profile: http://www.smolts.org/client/show/pub_cc9c7be0-2d64-43b6-8ee4-65f9565de32e
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. 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. Now, to get to these logs, we may need to be a bit creative: it could be possible you may get to your computer via ssh from another computer and collect the information this way. Also it could be possible to create LiveUSB (https://fedoraproject.org/wiki/How_to_create_and_use_Live_USB) instead of LiveCD and have some logs stored on USB (and next time you can 3 to the kernel command line and start without X). Or it could be possible to switch to the console via Ctrl-Alt-F2 (root should have no password). We will review this issue again once you've had a chance to attach this information. Thanks in advance.

Didn't know that root could have access without password ! From the logs seems that gdm has problems to start gnome-desktop, look at that abrt[2295]: saved core dump of pid 2209 (/usr/libexec/gnome-settings-daemon) to /var/spool/abrt/ccpp-1299782808-2209.new/coredump (42913792 bytes) For the record: I've a VGA monitor attached and by default, on boot, the gdm login is showed on the LDVS screen (i.e. the laptop lcd) and the display spans both monitors. This is a wrong default IMO, but maybe another bug should be filed for that(?).
Passing to developers, but also you can try new ISO image from http://alt.fedoraproject.org/pub/alt/nightly-composes/desktop/ ... there was unhealthy amount of fixes getting itself into F15 lately.
As of desktop-x86_64-20110317.14.iso I can now log-in with the external monitor attached. thanks
