Dell/Firefox/Windows 11 just had a stroke. I don't use a mouse, just the touchscreen and the touchpad. Monkeying about here and the system apparently froze. CTRL+ALT+DEL and things seemed to be working again so I hit "Cancel" and when I came back I didn't have a mouse pointer. Rebooted with no luck. Eventually went and got a wireless mouse from a different computer and that works. The stupid virtual touchpad that you turn on with the icon in the toolbar works. But the physical touchpad does not work. FN+F5 does nothing--although every other function key I tested does what it's supposed to do. None of the tutorials or tips are any help because they tell me to open Devices and Bluetooth (or whatever it was) and navigate to "Touchpad" but there is no "Touchpad" in Devices and Bluetooth--or ANYWHERE in the Control Panel. I hate 2026 so much.
(Dell had some troubleshooting that involved restarting, hitting F12, getting into a diagnostic mode, etc, but I'm just trying to unwind and destress so instead I just plugged a wireless mouse back in.)
