Description Tim Wegener 2011-09-09 02:06:31 UTC
Description of problem: An external monitor connected via the HDMI port is not detected under System Settings->Displays->Detect Displays. This seems to be similar to Bug 691429, but in my case a HDMI output is not even listed in the xrandr output: $ xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1920x1080 60.0*+ 40.0 1400x1050 60.0 1280x1024 60.0 1280x960 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.15.0-5.fc15.x86_64 xorg-x11-server-common-1.10.3-1.fc15.x86_64 kernel-188.8.131.52-5.fc15.x86_64 How reproducible: Always Steps to Reproduce: 1. Connect external monitor to HDMI port 2. Go to System Settings->Displays 3. Click Detect Displays Actual results: External monitor is not detected. Expected results: External monitor should be detected and used. Additional info: Dell Latitude E6520 Intel® Core™ i7-2720QM CPU @ 2.20GHz × 8 Intel® Sandybridge Mobile The monitor has been used successfully with another laptop. Booting with nomodeset did not help (but rather made things worse). Turning off Optimus mode in the bios didn't help (but rather made things worse).

Comment 4 Adam Jackson 2011-10-11 16:13:27 UTC
Sorry, that's how Optimus works. The non-LVDS digital outputs are only connected to the nvidia chip.
Comment 5 Ben Skeggs 2011-12-06 22:57:32 UTC
It's also worth noting your NVIDIA GPU is GF119, which while the graphics part of the chip is still a Fermi (current generation codename), NVIDIA redesigned quite a lot of other areas (including the display). This chipset was not supported in F15 (I don't think it was even around when F15 was released). F16 and up support your chipset, and if you're willing to setup an xorg.conf with multiple X screens (ie. you won't be able to move windows between them) you should get some functionality out of your external monitor.
Comment 6 Tim Wegener 2011-12-19 04:22:29 UTC
This should probably be marked as duplicate of Bug 691429. FWIW, I worked around it by just using analog VGA instead of HDMI for the external monitor.
Comment 7 Fedora End Of Life 2012-08-07 15:37:53 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
