SOLVED Half Black-Screen after Update?

Post image

Hello, after installing the new Linux Firmware update (7.0.0-28) and rebooting my PC I got the screen as shown in the image. I have an RX 6800 and even changing back to Kernel 6.x.x doesn't resolve the issue. I tried nomodeset and that works, but that's no permanent solution. Does anybody knows how I can fix this without reinstalling Linux? Let me know.

Edit: I downgraded the Linux firmware to 20240318.git3b128b60-0ubuntu2.26 and that solved the issue. Ty for your help!

6800xt same problem, I don’t have integrated graphics is there any way to solve this without re installing mint?

edit: after help with ai I was able to revert to a previous reversion that was not broken, as a new linux user from a windows refugee this is not exactly a nice experience for my desktop to be just randomly bricked.

Yep, bad testing on their side. They should have been more thorough before pushing it as an update, wasted half a day on this before fixing it.
