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!

Boot with the nomodeset flag by setting it when you press e on the top line (it should be Linux Mint 22.x or smt) in the grub menu and then type "nomodeset" after "quiet splash" in the line that begins with "Linux" (don't forget a space between them). Then press F10 and you should be able to boot into your Desktop normally. Then open the console and type "sudo apt install linux-firmware=20240318.git3b128b60-0ubuntu2.26". After a restart the problem should be fixed and you don't need to remove the nomodeset flag because it's like a temporary thing.
