[Kernel-packages] [Bug 1788044] Re: task kworker blocked for more than 120 seconds nouveau
I have found a fix. First I tried adding "nouveau.modeset=0" to bootflags, which got me to boot but no greeter. sddm appeared to be happily running but it failed to start the display server restarting it did not help "startx" worked, which gave me hope It appeared the session "seat" had been determined by systemd to have "CanGraphical" false Then I found this: https://github.com/mikhailnov/systemd/commit/c00bf275fdfbad3a9db8934b5e266b6abbdb8443 There's a heuristic hack which sets CanGraphical when the kernel starts w/o graphics, but only if this is done via "nomodeset" rather than the driver-specific ".modeset" flags So I just added "nomodeset" to boot flags, and now not only does 6.5.0-28 boot and land at a working greeter again, but all the weird sddm graphics bugs i'd been encountering since 6.5 are gone. Hope this helps someone else...

[Kernel-packages] [Bug 1788044] Re: task kworker blocked for more than 120 seconds nouveau
This is the closest, most recent report I could find with something which also appears kernel related Kernel 6.5.0-27 -- works fine Kernel 6.5.0-28 -- graphics hard-hangs - sddm never displays, vtty can't be activated shh works, sddm and x11 processes can not be killed, reboot hangs, hard power cycle required I see reports like this literally for years, yet seemingly no resolution. Now I'm bit, in a way suspiciously kernel version related Common internet "use nvidia drivers" wisdom is unworkable as old nvidia hardware is not supported on 22.04 04:00.0 VGA compatible controller: NVIDIA Corporation MCP89 [GeForce 320M] (rev a2) Again, for me, this is with 22.04, kernel 6.5.0-28 All the various combinations of nouveau flags to kernel boot which have helped reduce garbage or sddm troubles don't help.
