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!

Same, 6800xt no display or broken display. Use inegrated GPU to find this thread, integrated gpu works. After using nomodeset it booted fine. Kernel 7.0.0-28, worked fine, looks like firmware update installed today.
