I just "fixed" this: turns out, I have, at some point in the past, added `blacklist amdgpu` to `/etc/modprobe.d`, as part of an unrelated troubleshooting session probably, and forgot about it.
I don't know why that wouldn't break 6.5.0.13 as well; maybe `update- initramfs` failed or wasn't executed so the config didn't get into the `initramfs image`. Anyway, I removed the blacklist line and ran `update-initramfs`, after which everything works fine. Sorry for the distraction. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2049927 Title: [amdgpu] since Linux kernel 6.5.0-14 external monitors are no longer detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2049927/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
