Black screen and cursor after putting computer into sleep mode.
As of lately, I've encountered an issue on my laptop running Arch,
after putting my system into suspend, whether via terminal, the start menu, or closing the laptop lid,
once I wake up the laptop, the only thing I see is just my cursor on a black screen. The only temporary fix is to reboot my system.
I have checked for possible causes of the issue and tried several things such as uncommenting
and setting HandleLidSwitch, HandleLidSwitchExternalPower, and HandleLidSwitchDocked to 'ignore' in logind.conf, but to no success.
My laptop has an integrated AMD GPU with up-to-date drivers, so I doubt it is a driver issue.
I do use GDM with Plasma, Plasma 6.2 on X11 specifically, which the issue first started happening after I updated to 6.2
thanks.
[EDIT] It seems that several other people are encountering the same issue, I have reinstalled SDDM and at first, the issue appears to have been resolved, but after several reboots the issue recurs.

Re: Black screen and cursor after putting computer into sleep mode.
I have the same issue, although I have plasma running under Wayland.
I've also tried other DEs to see if the problem is specifically with Plasma, it is not, both GNOME and COSMIC (which I understand is still in alpha) have the SAME issue.

Re: Black screen and cursor after putting computer into sleep mode.
For IniMan and plasma specifically, sounds like it's either kscreenlocker or the compositor.
Try to suspend the latter w/ shift+alt+f12 *before* the suspend.
For kscreenlocker (might look like, but isn't SDDM - also didn't you say you're using GDM?) afaiu you can disable the screen locking in systemsettings.
In any event try to switch to a different VT (eg. ctrl+alt+F3) instead of rebooting the system (with the power button)
