Description Francesco Tapparo 2011-06-25 09:16:11 UTC
Description of problem:
gnome has to switch to fallback mode with external monitor attached.

Version-Release number of selected component (if applicable):


How reproducible:
This buf can be reproduced on a netbook samsung nc 10 with and external monitor plugged. when the netbook starts it always goes to fallback mode. If I unplug the external monitor and power the netbook on, gnome-shell runs fine, so it does not seem a performance related problem. I can also unplug the external monitor, start the netbook, wait until I'm logged inside gnome-shell and plug the external monitor. gnome-shell then automatically switches in the external monitor and runs perfectly fine.

Steps to Reproduce:
1. plug an external monitor to a samsung nc10
2. power the pc on
3. log in
  
Actual results:
gnome goes to fallback mode

Expected results:
gnome enter in gnome-shell mode

Additional info:
I tried to disable the external monitor using the "monitor" section of system settings but still I'm not able to run gnome-shell. it seems as the simple presence of the external plug makes impossible to have gnome-shell. I also tried to set the option to have the monitors cloned but it did not help.

If you need further questions feel free to ask.

thanks,
Francesco

Comment 2 Fedora End Of Life 2012-08-07 19:13:11 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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:
