Re: HDMI screen not recognised after upgrade Gnome 3.20
I upgraded to 3.20 and had some issues with the Nouveau drivers. Switched to proprietary Nvidia drivers and it worked much better. I'm using a DisplayPort3 however.

Re: HDMI screen not recognised after upgrade Gnome 3.20
Hello Thomas, For me sometimes the screen connected to HDMI is not recognized till I remove the cable and reinsert it after boot. Then I might need to press the key to activate external screen on my laptop. try "xrandr" command to get info about the recognized screens.

HDMI screen not recognised after upgrade Gnome 3.20
Hello all, I'm not sure if this is the right mailing list or if I should ask for help somewhere else (I'm not sure it's a bug so far...). Basically, the problem is simple, after upgrade of Ubuntu GNOME 16.04 with staging PPA, my external screen was working (plugged in with HDMI), even after the first restart. I went away and then switched off entirely my laptop, when I came back, no way to get the external screen recognised by the system (doesn't show on "Display" of system settings and doesn't show with randr command). Then, well, I used ppa-purge, but that didn't change anything and tried to plug in the screen with a VGA cable (and USB adaptor) and that still wasn't recognised. Finally, I tested the screen with another laptop (running Win 10) and that got the screen to work, so I'm pretty sure it's an issue related to the upgrade to Gnome 3.20. Would anybody be able to advise please?
