Same here. 1080Ti board. Upgraded to Linux Mint 20.3/Ubuntu 20.04 and Nvidia driver 510.39. The computer goes into standby, the monitor automatically shuts off. Video output remains off when I turn the monitor back on and I reawaken the computer. Unplugging and plugging the HDMI cable back in fixes it every time. I’ve seen people posting stuff about changing an nvidia-sleep.sh file, but no such file exists in my installation. I just rotated the PC chassis to give me easy access to the HDMI cable. I can imagine that doing this will eventually wear out the HDMI connector. I haven’t tried using a display port yet.
I’ve encountered the same problem. Happens with GTX 780 and GTX 980 on Ubuntu 20.04.3 with LG 43UP7000 and Hisense 43A6G. I wish NVIDIA would fix this.
Similar issues after installing GTX 1050 Ti with driver 510. Monitors wouldn’t receive signal after going into standby. Not even restarting the machine helped. Had to remove the GTX 1050 and hook a monitor into the integrated graphics. After re-installing the card I’m now back to driver 390.144, but monitor configuration still gets lost after suspending. Have to re-configure every time.
This happens to me as well, I’m currently on driver v470.86. using PopOS 20.04LTS. I find that after suspend, the HDMI is lost. Even sometimes after unplugging/replugging it will not come back (often time it “flickers” on briefly).
If I plug in to a different monitor, it works every time. It only seems to happen to me with an LG 4K monitor I use for work.
When I plugin the LG, I see syslog messages like this:

Hoping beyond hope this gets fixed…
I tried reproducing issue lately on below configuration setup but my display always wakes up after suspend/resume or even after turning back on monitor.
Precision T7610 + Ubuntu 20.04 LTS + kernel 5.13.0-28-generic + NVIDIA GeForce GTX 1080 Ti + Driver 510.54 + LG Electronics LG TV SSCR in 4k resolution
I will try to connect few other 4k displays to confirm if this issue might be specific to display.
This doesn’t always work for me, however this morning after booting up with HDMI plugged in, I was having the blank screen issue (i.e. it’s like things are being displayed to HDMI, but I can’t see them). After unplugging the HDMI and logging in on the laptop screen I was able to get HDMI working by going into gnome display settings and playing around with re-arranging the screens.
My setup is:
- LG 4K on HDMI
- LG 4K on DP
- Laptop Screen
The exact model of my LG monitors is: https://www.lg.com/us/monitors/lg-32UK550-B-4k-uhd-led-monitor
My laptop is an MSI GS65 w/ NVIDIA GeForce GTX 1070 with Max-Q Design.
Attached is my syslog from around the time I was re-arranging screens and got my HDMI back.
I believe the success happened at 09:04:08
Grateful for any help/guidance!

Just wanted to add that I can consistently get HDMI working again by pressing ctrl-alt-F3 to get into a textbased console, and then ctrl-alt-F1 or F2 to get back to graphical mode and the HDMI will work again. It’s an annoyance, but at least it’s a work-around.

I had to create an account just to thank you for this. My monitor was behaving in the same way; that shortcut saved my life. :D
Right on, glad to hear that.

Similar problems with a server running Ubuntu and NVIDIA Titan card and Samsung wide screen monitor. The only solution is unplugging the HDMI cable or CTRL-ALT-F3 and then ALT-F2. I can not change the driver because I use the CUDA drivers for machine learning. Very annoying. No solution from NVIDIA it seems.
i’m on 22.04, i’ve same problem, normally, after computer wakes up from sceen blank a few times, and then, the hmdi disconnects.
Same problem. Ubuntu 20.04, GTX 2060 Super, triple monitor setup with two 4k through display port and one 1080p with HDMI. I’ve been upgrading drivers from 460 up to 530 and still having issues. Would be nice if this got fixed by now. 2 years of graphics drivers not turning on a monitor seems like a pretty fundamental issue to me.
Not sure it’s an Nvidia issue. I have an AMD video card with Ubuntu 20.04 and I have the same issue with one of my monitors loosing signal after sleeping. The issue only occurs after lunch. All the other times throughout the day the monitors wake up without issue.
Having the same issue, except in my case, neither switching TTY nor unplugging and replugging the HDMI cable works. Switching to another HDMI port won’t work either, as I only have one on my particular card.
