I’ve been using Endeavour OS for a couple months now and I’ve really enjoyed the experience having come from windows. The only real blocker for me making a dedicated switch is that when I leave my computer long enough that the screen turns off (not sleeping), it will no longer receive a signal and r…

hey! Good to have you with us! This looks like a known bug that should be either fixed, or in progress ; you’ll find more information here : https://bugs.kde.org/show_bug.cgi?id=513151 Here’s how I worked around it : Powering off and powering back on the monitor, or - and here’s the bizarre bit, w…

I am able to blindly type in my password to log back into the machine, the picture just never comes up. I can initiate a reboot this way, but it sounds like it might be something at least slightly different. The machine isn’t freezing (as the bug you linked suggests). Also, power cycling the monitor…

All I can find is the below thread in terms of other experiences with this ; [image] Wake from Sleep/Standby/Hibernate - Blank Screen Kernel, boot, graphics & hardware So there seem to be quite a few threads on the subject. Most seem PC/system-specific. I’m go…

That post does appear to describe nearly identical symptoms as what I’m experiencing. Namely this: Whatever the choice, when waking, the monitor starts to wake and goes right back into sleep/stand-by. I have to hold the power button for a hard reboot. I installed the LTS kernel (6.12.63-1-lts) a…

I just happened to stumble upon another, probably significant, clue. When the signal is cut to the monitor, there is ~3 of time where the display tells me that it will enter standby when the timer expires. This happens as a part of the monitor’s firmware, so this would happen when there isn’t a sig…

Hooked up the only other monitor I have in my house with display port and it appeared to work flawlessly. That is my wife’s monitor, though.

I don’t have any monitors in my house. Being a non-gamer, I use 32 inch Samsung TVs using HDMI. Works good enough for my use case. Just for giggles and grins, got a spare HDMI TV to see what happens? Pudge

HDMI has never presented any issues as far as the screen being black. The only thing I don’t get out of HDMI is a higher than 60hz refresh rate. I would settle for 120hz if I had that option over hdmi and I didn’t have any other issues. I don’t have any TVs that wouldn’t have to first come off of t…

Edited: Have you tried updating the firmware on the monitor? You could also try a higher quality DP cable spec 2.1 Are you using the new nvidia-open drivers? Set the display port version to 1.4 in the monitor settings. Edit: Cable Quality: The G9 is notoriously sensitive to cables. If you are usi…

I moved to displayport a year plus ago, but I vaguely remember a period where I had to physically unplug my HDMI cable and plug it back in at the monitor-end to get it to recognise the display input. My only other suggestion, as bizarre as this sounds, (because they’re omnidirectional by design) is …

No signal when returning after screen turns off due to inactivity

Would be interesting to know if this happens on the LTS kernel.
