    If you run the following, does it help?

    Code:
    xset dpms 0 0 0
    Doesn't seem to unfortunately. It did change the settings to "Standby: 0 Suspend: 0 Off: 0" but still does the same issue.

    Now that I've permanently switched from X11 to Wayland I decided to do a few more tests. Via HDMI cable, the monitor will go into standby properly including on WL! Unfortunately I need to use DisplayPort for a few reasons... such as the HDMI connection only working at 120 Hz instead of the full 144 Hz, while also requiring me to boot with "amdgpu.dc=0" else the monitor won't turn on through this cable. It appears whatever the issue is, clearly only DP is affected... is it even the monitor's fault or a Kernel bug in the end? Does Wayland offer any monitor power management settings I can play with? I really don't wish to wear my monitor out nor waste electricity by keeping it turned on throughout the night... and I can't manually power it off either since if I do Wayland will freak out that there's no display and crash the session to the login screen, or switch to my VR headset as a primary display making it impossible to see anything and bring my monitor back on without rebooting.

    I am running xorg not wayland. I run using display port with a 165 Hz refresh rate and screen resolution of 2560x1440. I do not have any problem with suspending the monitor. GPU is a Vega 64.

    Silly question; are you using a Display Port cable that is D8k certified, or at least a version 1.4 cable?

    To be fair I don't quite know: I got a simple one from a nearby store thinking it wouldn't make a difference. Only info I can find so far is a label on it, photo below. On the official page of my exact monitor model, it suggests DisplayPort 1.2 is used... I'm thus assuming that as long as the cable is at least 1.2 itself, which it should be unless it's some crazy ancient model, that shouldn't make a difference.

    Any new thoughts on this please? I really don't wish to leave my monitor on during the night like that. If I could I'd use the HDMI cable which doesn't have this issue, but I can only use the monitor in 120 Hz mode over HDMI not 144 Hz like DP. Perhaps a different driver or kernel module is used for DisplayPort which isn't properly sending the standby signal to the monitor?

    Have you tested using DP with 120 instead of 144? If it behaves so configured, I'd think you found a(nother) bug to blame on Wayland that likely needs reporting upstream. I'm guessing not many testers or developers running 144 with 1080P on Wayland.

    WRT overnight, what about switching to empty login screen on vtty3 before off to bed?

    Another thought - what happens if connecting both HDMI and DP cables? I don't know if I'd want to try on a display that isn't under warranty, but yours is new. Does it have a manual that says don't do that?

    What if you try a live Fedora 32 stick boot, same problem with 144?

    Interesting suggestion: I didn't try putting the monitor in standby over DP at 120 Hz, didn't think that would make a difference. Might give that a go next... thanks.

    One thing to clarify: This issue exists on both X11 and Wayland (always KDE Plasma). In both cases HDMI will properly go and stay in standby, but DP will fully cut off the signal instead. This makes me suspect it could be an amdgpu or other kernel issue.

    Tried enabling standby on both 120 Hz and 60 Hz, no difference. Also set the monitor to request the YUV color format too but this didn't help either.

    Anything else? I'd really appreciate more input from anyone who: Uses openSUSE Tumbleweed, an AMD card on the amdgpu module, an 144 Hz monitor, and is connecting their monitor via DisplayPort... should be common things and hopefully a known bug somewhere.

    Edit: It appears another OS-TW user posted about the exact same problem with the same hardware and configuration as me. No responses to their thread yet but I'm clearly not the only one.

    Hi
    Any firmware updates available for the Monitor?

    Code:
    hwinfo --monitor (Intel GPU though)

    Only amdgpu systems are laptops with HDMI....

    Could be the monitor(s), could be the card, could be the desktop.... So if you logout and login into ICEwm, does the issue duplicate?
