Idk it worked perfectly with firefox on my switch, idk if a wireless mouse would work. btw if you want to use a mouse use the joycons you can connect them with bluetooth
When i overclock to 2.0ghz ubuntu runs even slower, before the overclocking, dolphin ran at 15-50fps, after overclocking to 2.0 it runs at 2fps, even at the strap screen (i was testing out nsmbwii)
