Description of problem: Having 2 screens connected ( one internal laptop screen + external dvi ) on a dell E6500 using the nouveu driver, everything works well until after i try to login to gnome3. So it displays the gdm but after i submit my login details both screens turn black and they stay that way even after i disconnect the external screen. It is even not possible to open another tty. Version-Release number of selected component (if applicable): How reproducible: Every time i try it. Steps to Reproduce: 1. Boot up. 2. Login to gnome3 desktop. With the nouveay driver. 3. Actual results: Screen turns black and only reboot seems to help. Expected results: Picture should be visible on both screens. Additional info:
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 attach your X server config file (/etc/X11/xorg.conf), X server log file (/var/log/Xorg.*.log) and the output of "dmesg" to the bug report as individual uncompressed text/plain file attachments using the bugzilla file attachment link above called "Add an attachment". Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thank you in advance. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Created attachment 496435 [details] Xorg.0.log that is the result of no xorg.conf in place This is the Xorg.0.log resulting from trying with no xorg.conf
Created attachment 496437 [details] dmesg output the dmesg output. I do not have an output from Xorg.log with a xorg.conf present. It works however without it when no external screen is connected. So I have only run this without an xorg.conf present, I should maybe have been clear about this from start.
Additional info. The external screen is connected through dvi on a dock coming with the dell e6500. It is also verified to work with the proprietary nvidia driver. And to be clear the screen turns black first _after_ i have submitted my login details to the gdm greeter, and I should have seen the gnome3 desktop.
Same problem here: When I connect an external monitor to my ThinkPad T61 both screens go black with no picture. I had to activate the "X11 ZAP" functionality or had to hard turn off the laptop. Both screens work during boot-up and gdm. They go blank right after logging into Gnome3 or when plugging the 2nd monitor after being in Gnome 3. The exactly the same configuration worked in Fedora 14,13,12,... $ lspci | grep -i VGA 01:00.0 VGA compatible controller: nVidia Corporation G84M [Quadro NVS 140M] (rev a1) $ rpm -q gnome-shell gnome-shell-3.0.2-1.fc15.x86_64 I'm running without the xorg.conf file.

here is another one that has the exact same issue it seems https://bugzilla.redhat.com/show_bug.cgi?id=707933 So maybe a duplicate then.

As noted in my duplicate bug, I have this same problem on my Dell Studio XPS 13. % lspci | grep VGA 02:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce G210M] (rev a2) 03:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M G] (rev b1) % rpm -qa gnome-shell gnome-shell-3.0.2-1.fc15.x86_64 I am connecting via HDMI-DVI cable to an external 24 inch monitor (1920x1280). I did get it working once using a VGA cable.
It seems the latest updates to nouveau have fixed this problem for, and I am able to run gnome-shell on my external monitor. The updated versions are: xorg-x11-drv-nouveau-0.0.16-24.20110324git8378443.fc15.x86_64 xorg-x11-server-Xorg-1.10.2-1.fc15.x86_64
I have those exact versions but the problem is still exactly the same for me though, the login (gdm) displays perfectly fine on both screens but when I login to gnome both screens turn black.
That's strange. The other thing I may have done recently was (due to an unrelated incident), I deleted my .cache .local .gnome .gnome2 directories so I lost all my previous settings from Fedora 14. Maybe a clean account fixes it?
I can confirm this now after trying. It seems as it is that if i edit the display properties to disable the internal screen and only use the external one (System Settings -> Displays ) as i seem to have done previously it causes this. So i am now unsure where the bug is if it really is the driver causing it.
I am able to disable the internal screen and run off only the external monitor.
Just had it happen again. But after I deleted ~/.local/screen-configurations.xml and rebooted, it worked again. Strange....
Hi, I had the same problem in my ThinkPad T61. It started happening after setting a wrong configuration in System settings -> Displays. For some reason, the old configuration didn't reset after 30 seconds. After checking that a clean account (I tried a new user) didn't have the same problem, I fixed the problem for my user removing the file ~/.config/monitors.xml. I'm attaching both monitor.xml files, the one that caused the problem and the new one.

Created attachment 512352 [details] Wrong monitors.xml file
I tried deleting ~/.local/screen-configurations.xml and rebooted. I still got only the display on my Dell E6500. Then I deleted monitors.xml and rebooted. I still get only the display on my laptop. The second monitor is not detected.
My current workaround is this (when connecting my laptop to an external monitor): 1. In /etc/rc.local, I delete the monitors.xml in .config 2. After I login, the main screen is on the laptop. I run display, which will show both monitors 3. I move the gnome shell bar to my external monitor and press apply 4. Then I turn off the laptop screen and press apply From my experience, steps 3 and 4 need to be done separately (and in that order too). If I try to move the gnome-shell bar and turn off the laptop screen at the same time before pressing apply, I get the blank screen problem.
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.
