The drivers are more stable than the standard ones on my end, but it is not saying much. I was actually able to log in to X11 with the open kernel without immediately getting a black screen, which is an improvement over getting a black screen immediately with no other choice but to remove the drivers with Timeshift. However, I am only able to log in for like a minute or so before I get a black screen that then throws me back to the login screen. Wayland doesn’t work at all and just throws me back to the login screen.
One more benefit is that my Cintiq screen didn’t immediately black screen OpenMandriva before even reaching the login screen. Both my screens worked for the brief period that I was able to log in.
Will try this again in the future once the 570 drivers are finally available. Hope this feedback is of any use in the meantime.
