[Trisquel-users] Re : Screen tearing and high CPU

[lcerf]

If you never type Chinese or Japanese or Korean or Vietnamese or Thai or ...  
characters, then choose no keyboard input method system in the "Language" tab  
of "Language support" in the "System Settings". Also, ~/.xinputrc (that is,  
the hidden file named ".xinputrc" in your home folder) should have "run_im  
none" and not "run_im xim" (or any other input method).

The graphical session may have be restarted for the changes to be effective.
