I installed Fedora 25 as dual boot next to Windows 7. I have Turkish layout keyboard. And OS is in Turkish also. All the other buttons work and write normally, but buttons  i, , alt gr dont function at all. These buttons work normally on Windows 7. output of setxkbmap -printxkb_keymap {  xkb_keycodes  { include evdev+aliases(qwerty) };    xkb_types     { include complete  };  xkb_compat    { include  complete    };  xkb_symbols   { include pc+us+inet(evdev) };    xkb_geometry  { include pc(pc105) }; };and when I run xev as normal user and type characters, everything works normally.evtest did not work in root user.And I noticed that , when I type on terminal everything is ok. 
Some letters on my Turkish-layout keyboard don't work on Fedora
fedora;keyboard
I run setxkbmap tr and It got fixed.
