"I had problems with @, <, and >, so I did the following: Code:
xmodmap -e ""keycode 53 = x X greater greater greater greater"" xmodmap -e ""keycode 52 = z Z less less less less"" xmodmap -e ""keycode 24 = q Q at at at at""
Which solved those three... though I have no idea why the problem occurs in the first place."
