I’ve been getting a strange display issue that I’m looking to narrow down and/or see if others have encountered it.
I’m running Linux Mint with Cinnamon on my FW16. Sometimes when my screen locks or my system goes to sleep, when I wake it up and sign back in, I get these extremely abstract designs that flicker heavily on my screen between the normal display:
If I restart Cinnamon (Alt+F2, r), the issue usually goes away. I’ve also restarted X11 (Ctrl+Alt+Backspace) as a solution and that has also worked, until my screen is locked again.
I have unplugged the connector to the LED display and reconnected/re-seated it, but still encounter this issue. Since a restart of the environment usually clears the issue, I don’t think it’s a display cable issue…
So my question here:
Is this an issue with Cinnamon, or perhaps Linux Mint, or is this some sort of deeper hardware issue?
I’m aware that there is no official support for Mint, but I wanted to see if anyone else has seen this issue. I may try live-booting into Fedora or something and seeing if this issue happens in there.
Thoughts?
EDIT: I can provide some deeper info about what kernel I’m running, etc:
Kernel - 6.5.0-35-generic
Cinnamon version - 6.0.4
Mint version - 21.3
I’ve been running the Edge version since I got mine without problems,
also I think there were some very similar looking problems with the AMD version of the FW13 on older 6.7 kernels.
Can you run a live system with Mint Edge or one of the official supported distros?
I ran a live system with Fedora with Xfce the other day and ran tests with screen lock and logging out and back in. I didn’t get any abstract designs during testing during then.
I may try spending more time in the live system and get more data.
Spent more time in a live boot with Fedora Xfce, having the screen lock from inactivity, manually locking, closing the lid, suspending and reawakening, and combinations of the previous.
Thus far I haven’t gotten any screen abstracting.
I also made a live boot of Mint Edge, got that running, and performed the same sort of testing and also did not get any abstracting.
I’ve decided to do a fresh Mint Edge install, and will see if I encounter the issue any further.
It’s been a few weeks since my fresh Mint Edge install. I haven’t encountered the display issue since then. So if you intend on running Mint, be sure to install Mint Edge. Marking post as solved.
