After install Ubuntu 20.04 I tried to connect a second monitor via HDMI in my laptop ASUS ( Intel® Core™ i5-6300HQ CPU @ 2.30GHz × 4 ) - (Nvidia GeForce GTX 960M ) and Ubuntu and Nvidia settings detects I connected it, but the only thing I can see is a blank screen.
I tried with a Live USB, I have the same result. I tried to modify the xorg.conf (I added “Primay GPU” “Yes”) and nothing changes.
Anyone had this similar problem? Or someone can help me and tell me how can I try to fix this? On Ubuntu 18.04 and W10 it works perfectly.
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).
I’ve taken a closer look and the external monitor is connected to the intel gpu so it should work regardless of the nvidia gpu being on or off.
It’s also detected and used in both the nvidia-bug-report.log. Did you already check if it’s just disabled in Gnome’s control center? It should be shown there.
Yeah, I saw that on Nvidia-settings and I was wondering why Nvidia can detects it but I can’t see anything in the monitor. But on W10 it works perfectly.
But I just can only see a blank screen (no signal). When I start Ubuntu, and I’m in the grub the second monitor works perfectly, it’s only when I go to load the OS (after choose “Ubuntu” in the grub). So strange…
Rather odd, especially since it works on console. Rather sound like a problem with the intel gpu firmware. Please open a bug report on the Ubuntu bug tracker and confirm it still works with 18.04.
Hi,
