Yes, and Google captchas are the worsts of all of them.

I found Buster a while ago and works most of the times, it use the accesibility audio challenger to try to solve it using speech recognition. When it don’t work I found more easy to try the audio challenger, you just need to write the part that you understand and not all you hear, less picky than the images, still a pain in the ass

Looks like SysRq keys are not enable in your distro by default, don’t know the reason but Fedora kernel devs would known better than me.

Just for curious, did you installed some gnome extension recently? try this

grep -i gnome-shell /var/log/syslog* | grep -i exten

What about dmesg? if it’s a hardware problem (and it looks like, but I may wrong) dmesg will print some usefull data

sudo dmesg -Tw

-T form human redeable timestamp and -w to follow (like tail -f)

Also, about that hard reset that you did, Linux magic keys are your friends if your are not facing a kernel panic, I have this key combo engraved in my head like a rune:

Press and hold Alt + PrtSc (not Alt+Gr) and then press only one time each (and while holding Alt + PrtSc) E + I + S + U + B

PrtSc maybe be SysRq in your keyboard depends on the manufacturer, architecture or how old it is. Also wait one or two seconds between keys when pressing EISUB.

Edit: the rune in my head was wrong, fixed it

Probably is not going to make your phone experience much better but I followed this to disabled (not uninstalling) some stock apps on stock Android phones, works great and if you made a mistake it’s easy to rollback.
