After upgrading to 24.04, I also have black screen on a 2009 mac mini (9400) To be precise, It freezes on a distorted NVIDIA logo, and Xorg runs on 95% cpu constantly.
I see no errors in Xorg or xsession-errors, although, this one is a little suspicious in boot log: febr 13 15:45:55 macmini kernel: WARNING: kernel stack frame pointer at 00000000d4c85980 in nvidia-smi:643 has bad value 000000001c6f619c febr 13 15:45:55 macmini kernel: unwind stack type:0 next_sp:0000000000000000 mask:0x2 graph_idx:0 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-340 in Ubuntu. https://bugs.launchpad.net/bugs/1916640 Title: Nvidia 340.108 driver is not working newer kernel series than 5.10.x Status in nvidia-graphics-drivers-340 package in Ubuntu: Confirmed Bug description: As usual I have opened this (no more) new bug report...
