I haven't had any problems after removing the intel drivers. Closing.

Forget what I said about disabling the screen lock, I finally got a black
screen with a mouse pointer and was not able to view by desktop.

Also I tired pressing my power button to try to put system into RAM suspend
mode, nothing happened. The moused pointer still movable but entire screen was
black. Forced to do hard reboot.

Here is my info video info:

I notice that I see the same black screen right before screen locker shows up.
At least so far with mode setting driver I am able to reach screen lock but
with intel I am just stuck at the black screen.

Ever since I've disabled "Lock screen on resume" my system starts up in a flash
from suspend to RAM. I haven't experience a black screen.

I suspect there is a bug with the login session manager, if I had to login in
coming out of suspend by now I would have experience a black screen with a
mouse point and forced to reboot. I don't think the issue is related to a video
card or driver issues. With my experience the issue is the login screen or
session manager.

>What are the next steps if Intel drivers are indeed the problem?

Well then we cannot do much about it. It's pointless to try to report it
upstream, that driver has been in an unreleased state for years. Distros are
switching away as well.

I haven't had a problem freeze in the last few days since I switched to
modesetting drivers by removing the intel.

I will test for few more days.

What are the next steps if Intel drivers are indeed the problem?

Beginning with server 1.17.0, the separate modesetting driver package was
eliminated and the driver incorporated into the server. To switch to the
modesetting driver in distro releases providing 1.17.0 or newer, simply
uninstall the intel driver package and restart the server.

I am also seeing this issue and have disable "Lock screen on resume" to
eliminate the login screen. Will continue to monitor and report back if the
screen remains black.

This doesn't sound like a problem in our software, but rather in deeper in the
stack (Xorg, OpenGL driver or drm). First of all: if you are using Intel
hardware please switch from xorg-intel to xorg-modesettings driver and check
whether the problem persists.

If that doesn't help, please try to investigate a little bit more. E.g. check
with dmesg or in /var/log/messages and /var/log/Xorg.0.log for error messages
related to what you see. Also try to unlock the system without using the
greeter:
loginctl unlock-sessions
