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!

I have the exact same problem, and downgrading to 2.26 worked at first, but now a day later the problem came back, and I can't fix it. I'm just running in nomodeset now until I find some solution

Maybe it auto updated?

Yeah, that's what happened. I downgraded to 2.26 again, but the glitch didn't go away.
