Running Byzantium on my Librem15rev3, every now and then (often when I am switching between Workspaces, but not always) I experience screen freezing. Audio streams continue, but I can’t move the mouse or keyboard. When I close the lid, the laptop goes to sleep (suspends) after some time. Depending how long it stays that way, it either wakes up with the same frozen screen, or (after a longer period of sleeping) comes back with the unlock screen.
Another thing I notice is that when I reboot the laptop, the screen will be flickering until I put it into “suspend” for a brief time, after that it will function normally.
After reading this post https://puri.sm/posts/update-on-librem-ec-1-12/ , I am wondering if this could be related to the setting of power limits? How could I verify this? Can this be logged somehow?
