hello i have problem after updaed to kernel 6.5, the screen goes black (doesn't display anything), after entering password in login screen but after i revert back to kernel 6.4 or 6.1LTS, booting is OK, no problem here is my hardware specs : (output from inxi -Fazy) https://0x0.st/HWrO.txt here is output of journalctl at booting with 6.5 https://0x0.st/HOnf.txt and here is output of journalctl at booting with 6.4 (for comparison) https://0x0.st/HOnm.txt i have reported this at manjaro forum : https://forum.manjaro.org/t/kernel-6-5-doesnt-work-with-amd-a9-apu/148383/13 laptop works fine with kernel 6.4 / 6.1LTS, just i am curious why 6.5 doesn't work (& based on my personal interpretation from journalctl output, it may related with KDE...) any help is deeply appreciated
the pattern of this case had been found : case occurs only when scale at display setting < 100% in kernel 6.5 scale < 100% & kernel 6.5 >> problem occurrs scale < 100% & kernel 6.4 >> no problem scale = 100% & kernel 6.5 >> no problem i hace created separated bug : 475904
If a kernel upgrade reproducibly breaks something, then it's a kernel regression. Per Bug 475904#c8, it looks like that's exactly what happened.
