Hello, last friday (4th of June) my drivers were automatically updated to the current version 460.80 on Ubuntu 20.04. Now if I turn my monitor (SWEDX display) off or it goes to sleep, and I turn it back on I get ‘No Signal’. This was not the case until now. Only if I unplug the HDMI cable and plug…

I have the same issue on Ubuntu 20.04 and 21.04. NVidia driver 450.xx works without any problem (the latest one tested is 450.119.03) If I install 460.x or 465.x the issue manifests and there is no signal after monitors sleeps. I also tried NVidia beta 470.42.01 - the issue is still present…

After upgrading video driver, using 460 driver my HDMI connected monitor did not wake up on boot on my dual setup. The Displayport connected monitor worked. The HDMI seems to work better when I but it to 2K instead of 4K. Changing TTY woke it up. I also installed the 450 server driver. At first i…

hi, similar issure here with a 1060 5gb and a philips 34SE2 ultrawide 3440x . If I switch from hdmi1 (my desktop with linux and nvidia) to hdmi2 (second device) everything is fine. When I switch back to hdmi 1 the monitor reports “no signal”. Replugging the hdmi cable of the nvidia machine brings t…

I am now on Ubuntu 21.10 with Nvidia drivers 495.44 and the problem persists. Switching TTY with ctrl-alt-FNx helps most of the time to bring the monitor back on. Is there really no other fix then reverting to driver 450 …?

I disabled “secure Boot” on my computer bios and it worked. It’s recognizing my external BenQ monitor.

+1 with a the same problem I think. Lenovo Extreme X1 Gen 2, was on 20.04 LTS when I first hit this problem after upgrading beyond 450, rolling back to 450 fixed the problem. Had been on 21.04, with drivers pinned to 450 via /etc/apt/preferences.d file. Just upgraded to 21.10 which forced me to 470…

Same on Ubuntu 18.04.6, with a GeForce GTX 1050. Tried every other driver available, and only the 450 version (450.156.00) allows me to toggle away to a different input on my monitor, and then toggle back and still have a signal. In my case, my screen is a TV, with an AV receiver in between (and t…

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 …

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.

Ubuntu 20.04 'no signal' after monitor sleep or monitor turned off

450 does help me obtaining these basic monitor functions (off and on).
Other problems with internet connection and gdm3 seem to appear. Hopefully these problems are less serious than they seem.

Thanks for the input!
