Filed from caserun https://tcms.engineering.redhat.com/run/288296/#caserun_13122785 Version-Release number of selected component (if applicable): xorg-x11-drv-nouveau-1.0.11-3.el7.x86_64 Steps to Reproduce: 1. reboot machine 2. disconnect monitor while machine is shutting down 3. wait until machine is rebooted to GDM 4. connect display back to the machine Actual results: Screen is black, only mouse cursor appears. It is possible to switch to virtual console, fbset shows resolution 1024x768 (should be 1920x1080 in my case). Restart of GDM service lead to showing up of logging screen. Expected results: Screen should be correctly powered on with native resolution. Graphics card: NVIDIA Corporation GK107GL [Quadro K600] [10de:0ffa]
When powering off, screen with circle progress bar is of resolution 1024x768.
Occurs also with NVIDIA Corporation GK107 [NVS 510] [10de:0ffd] with xorg-x11-drv-nouveau-1.0.11-4.el7.x86_64.
I can still reproduce with kernel-3.10.0-681.el7.x86_64 xorg-x11-drv-nouveau-1.0.13-2.el7.x86_64 xorg-x11-server-Xorg-1.19.3-7.el7.x86_64
(In reply to Tomas Pelka from comment #5) > I can still reproduce with > > kernel-3.10.0-681.el7.x86_64 > xorg-x11-drv-nouveau-1.0.13-2.el7.x86_64 > xorg-x11-server-Xorg-1.19.3-7.el7.x86_64 What do you see in the kernel log after attempting to reconnect the display? The 1024x768 resolution of the console is the expected behaviour (the console fb can't be resized, on any driver, so it's determined based on connected displays at module load time), but inside gdm, it should indeed be native resolution.

also issue with 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK106 [GeForce GTX 660] [10de:11c0] (rev a1)
GM206 too
GM107 too
Not reproducible any more on RHEL 7.6 with packages: kernel-3.10.0-940.el7.x86_64 xorg-x11-drv-nouveau-1.0.15-1.el7.x86_64 xorg-x11-server-Xorg-1.20.1-1.el7.x86_64 After attaching screen the GDM is shown in correct resolution. Tested with GM107, GM206 and NVS 510.
