I had some other trouble like Ubuntu 22.04 Wayland Freezes earlier though this one seems different. In case it helps:

  • Silly question, but are you using display scaling? Maybe 125% or 150%? Is this on a 12th Gen Intel CPU? – matigo Oct 13 '22 at 05:38
  • Forced to use power button? So you're saying you couldn't use SysRq commands direct to kernel to reboot/shutdown safely? ie. your issue is kernel panic? (ie. anything on user level, including all GUI/terminal functions (ie. screen/terminal completely stuck) will not prevent the kernel accepting commands directly) – guiverc Oct 13 '22 at 06:00
  • Default display scaling. Yes keyboard and mouse were completely unresponsive, though I did not think to try the Ctrl + Alt + F6 and Ctrl + Alt + F2 keys - they are a very well hidden “feature” – pzrq Oct 14 '22 at 06:11
  • Yep Settings > About > Processor is showing 12th Gen Intel Core i7-12700H x 20 – pzrq Oct 14 '22 at 06:14
  • I mentioned the SysRq commands which bypass any stuck gui/display issue & go direct to the kernel. If unsure what they are, given they aren't a Ubuntu feature - but a kernel function, grab a phone & search "magic sysrq" and the wikipedia article is usually near the top. Using them is almost certainly guaranteed to work (they won't work if you have a kernel panic, and having that is extremely useful diagnostic detail!) if you have a real keyboard (thus no good on an android phone which requires the working GUI for onscreen keyboard to work! let alone no SysRq exists there) – guiverc Oct 14 '22 at 06:31
  • do note: SysRq was always written on the front side of the key, so many modern keyboards (which are very then thus writing on the front face wouldn't be visible anyway) still have the function available, but the key label isn't usually seen on modern laptops; it's still present though, but some require an extra Fn key to be used. If you look at a real keyboard (especially older & not chiclet) you can see where it's located - it's the same key on modern dell/hp/lenovo/etc even if not marked. (a quick look at a sony vaoi & I can see key to use, on samsung nothing seen but easy to guess) – guiverc Oct 14 '22 at 06:35
  • Took me a while to find a keyboard with a Sys Rq key on it (the laptop does not have it) and further it looks like I'd need to enable it as Ubuntu now just basically calls Print Screen, including with the Alt + Prt Scr, super and Fn keys so I'm out of ideas on actually triggering this magical Sys Rq: https://askubuntu.com/questions/911522/how-can-i-enable-the-magic-sysrq-key-on-ubuntu-desktop – pzrq Oct 19 '22 at 01:29
