For some very frustratingly unknown reason, something seems to be capturing the output of my ancient keyboard (105-key 4-pin PS2 standard, no extras) which disables regular typing keys, when using Shift+←↓→↑ keys for text selection. Issue remains with or without +Ctrl.
The problem is definitely software (settings) issue, as some functionality remains available (like: Shift+←↓→↑ or Ctrl+Alt+F#). I've sometimes managed to re-enable keys by mishap via (unnoticed) keypresses.
This problem occurred on that hardware setup just within recent days, first time ever. Until then, Ubuntu has been running on it flawlessly, over several months. Probably it has been there for days, while remained unnoticed, as I really have not dealt with text editing in a week or so.
Currently I can re-enable keys by re-selecting mine keyboard language from topbar (shortcut keys: super+space). But it drives me nuts enough for repressed urge to use keyboard as bat and play some Piñata with the monitor.
No help from:
- switching to alternate keyboard language.
- changing keyboard to
- removing keyboard language alternatives (so just initial one from live/install CD remaining);
On reasons, I'd suspect issue to be introduced since following action (performed several days ago, and needed for currently unfinished project):
sudo apt install inxi fancontrol hddtemp
I've also done
apt dist-upgrade since then.
No Gnome Addons enabled, but default Ubuntu ones (disabling them did not help either)
Gnome Tweaks is installed and I do have fiddled with it's settings, but not at the time period of problem occurrence. Recently tried out to variate it's options with no prevail. Same goes to Gnome Settings.
In the end -- while issue is highly frustrating -- it also intrigues me: what, how and why did skew mine settings like that.
