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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916640 Title: Nvidia 340.108 driver is not working newer kernel series than 5.10.x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1916640/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
