Created attachment 860094 [details] The result of running lspci -v Description of problem: My new Toshiba satellite laptop has a VGA and a HDMI interface for an external monitor. Under Fedora 20, the VGA interface is not recognized when a monitor is plugged into it, so it is not possible to display externally. Version-Release number of selected component (if applicable): 3.12.9-301.fc20.x86_64 How reproducible: Every time. Steps to Reproduce: 1. Turn on the computer. 2. Connect an external monitor to the VGA connector. 3. Go to Settings / Display to enable the monitor. Actual results: The monitor is not listed as an available device. It does not report a signal, the only message on the monitor being "no signal". Expected results: The monitor should be listed as available, and the monitor message should change to show that it is receiving a signal. Additional info: I have tried rebooting, but there is no ouput on that monitor even during the boot process. The monitor was detected without problem on this machine under Fedora 19; booting output would go to the external monitor if it was turned on prior to booting. When I run "xrandr -q", all it sees is: xrandr: Failed to get size of gamma for output default Screen 0: minimum 1366 x 768, current 1366 x 768, maximum 1366 x 768 default connected primary 1366x768+0+0 0mm x 0mm 1366x768 76.0* Under Fedora 19, I was able to use the external monitor as a separate screen with the command: xrandr --output eDP --auto --pos 0x0 --output VGA-0 --auto --right-of eDP
Please attach the output of dmesg from a fresh boot. Also, when you say Fedora 19, which kernel version were you speaking of?
I do not have records of the kernel version in Fedora 19 when I had success. I still have the Live-CD and the version of the kernel in that was 3.9.5-301. When I boot with that CD, the screen of the external monitor comes up with vertical coloured stripes, so the monitor is detected but the graphics to it are wrong. After installing from the live-cd, I did a "yum update" so it would have been a more recent version that the one on the CD that I had success with. I will attach three dmesg files: from the current release without the monitor attached, the same with the monitor attached, and from the live CD with monitor attached.

Is this bug still not fixed? Waiting for this fix before moving to fedora 20.
No, the bug has not been fixed. Although I cannot confirm it, I suspect that the problem is related to the hardware. My machine has an HDMI port as well as the RGB port. Sound does not work on my machine either. The RGB port works fine under Windows.

Dell Latitude E7440 laptop. 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) (prog-if 00 [VGA controller]) Any external monitors attached via the HDMI ports or a docking station show as a single monitor with the kernel 3.16.6-203.fc20. While not optimal this configuration worked flawlessly being able to migrate from laptop to laptop + dual heads to laptop + projector etc. It was stable and usable. With the new kernel 3.17.2-200.fc20 dual head monitors now show up as two monitors as one might expect but once you migrate to them and then back off of them you can never migrate to the dual heads again. Any attempt will crash arandr or xfce4-display-settings. If you continue to try sometimes X crashes. Similarly if I attach a projector(external hdmi) it will migrate to the projector and laptop screen but if I try to disable the projector it appears X crashes just before the entire system hard locks and requires a cold boot. In addition if you boot without the system on the docking station external monitors will not be detected unless you restart X. This is similar to the bug described previously. Another odd item to add is "arandr" works perfectly with the old kernel(3.16.6-203.fc20). xfce4-display-settings is flakey. With the new 3.17.2-200.fc20 xfce4-display-settings works only to migrate to the dual head but fails going back. arandr only works migrating to the projector but fails going back. Sorry for the scattered aspect of issues above but it would seem the new kernel, presumably the driver for the Intel cards, is really buggy in comparison.
I am having a similar problem with an upgrade to Fedora 20. I have a Lenovo T540p with a docking station and external 27" Acer monitor. The upgrade from 3.16.6-200 to 3.17.6-200 broke a lot of things and I have had to revert. When I remove my laptop from the docking station, I'm logged out and the screen dims to the lowest brightness level. I have to log in again, but have lost all my work. When I redock my running machine, it does not recognize the external monitor. I have to shut down and boot while the machine is docked.
There is no change to the symptoms on my machine since the rebase to 3.17.2-200.fc20. The computer does not see that there is another monitor present, and the monitor reports "Check signal cable".
I have the same problem after upgrading to Fedora 21. Both monitors are connected, one on VGA and the other on HDMI. I get image on both, but they are cloned, and I cannot use extended anymore. When I try to change the settings, the monitors are not listed. Here is some data: uname -a ...... 3.17.4-301.fc21.x86_64 .... My old kernel was 3.17.3-200 xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 0mm x 0mm 1920x1080 0.00* lshw -c video *-display description: VGA compatible controller product: Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:28 memory:f7800000-f7bfffff memory:e0000000-efffffff ioport:f000(size=64) I actually use the integrated graphics from Intel i5-3450.
In my case it was related to the graphics driver. I solved it by reinstalling xorg-x11-drv-intel. Somehow it worked after this operation. Unfortunately I couldn't solve it a smarter way, it's beyond my knowledge.
The problem that I originally reported, that my Toshiba laptop is unable to detect an external monitor plugged into the VGA socket, persists in Fedora 21. There was no problem under Fedora 19, but it ceased to work with Fedora 20. The hardware works fine under MS Windows. My problem is different from what Ion Dulgheru reports. I only get visual output on the built-in screen. The external monitor displays the message "Check signal cable", and the Display configuration tool only lists "default" as available to display onto. Reinstalling xorg-x11-drv-intel makes no difference.
I suffer from a similar issue with a HP Elitebook (Intel + ATI). My external monitor is detected only once and I have to reboot to connect it again.
I suffer from the same issue that other in fedora 20. I just installed fedora 21 from a clean instalation and i just see the second monitor in stan-by it never go active. $ uname -a 3.18.3-201.fc21.x86_64 $ xrandr Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096 VGA-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.00*+ 1680x1050 59.95 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 DVI-I-1 disconnected (normal left inverted right x axis y axis) TV-1 disconnected (normal left inverted right x axis y axis) $ sudo lshw -c video *-display description: VGA compatible controller product: NV44 [GeForce 6200 TurboCache] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:29 memory:f6000000-f6ffffff memory:e0000000-efffffff memory:f5000000-f5ffffff memory:f7000000-f701ffff I'm using the VGA to my first monitor and integer VGA to second but it doesn't work. when I connected the VGA and monitor internal VGA won't work anymore.
It seems to me that upgrading the kernel to 3.18.5 (and maybe 3.18.4) may solve the issue. This kernel is available in testing if you want to test.
I installed OpenSUSE on the machine with 3.16.7 kernel. The problem disappeared with their tuning of the kernel.

Graham, Have you tried Fedora 22? I think I am experiencing this same bug on 22. Dell 7000 series laptop. Integrated Intel GPU. The HDMI port was functional and I could hot plug under Fedora 19 and 20. Under Fedora 21 and now 22 the HDMI port has vanished. xrandr output: xrandr -q --verbose xrandr: Failed to get size of gamma for output default Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected primary 1920x1080+0+0 (0x181) normal (normal) 0mm x 0mm Identifier: 0x180 Timestamp: 132179 Subpixel: unknown Clones: CRTC: 0 CRTCs: 0 Transform: 1.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 0.000000 1.000000 filter: _MUTTER_PRESENTATION_OUTPUT: 0 1920x1080 (0x181) 159.667MHz *current h: width 1920 start 0 end 0 total 1920 skew 0 clock 83.16KHz v: height 1080 start 0 end 0 total 1080 clock 77.00Hz lshw output: lshw | grep display -A 50 *-display UNCLAIMED description: VGA compatible controller product: Haswell-ULT Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list configuration: latency=0 resources: memory:d0000000-d03fffff memory:c0000000-cfffffff ioport:4000(size=64) uname output: uname -a Linux localhost.localdomain 4.1.3-200.fc22.x86_64 #1 SMP Wed Jul 22 19:51:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
I haven't tried Fedora 22. After being unable to use the VGA port in Fedora 20 and 21, I switched over to using OpenSuse. It was able to detect the external monitor without any modification.
