I used to start the game,Frozen Throne (using wine) with the option of "-opengl".When I entered the game,the resolution will changed,and restored after exit the game.

But this time a problem happened.The resolution can't restore although I restart my computer several times. Both the Ubuntu pane and login windows are exceptional. nvidia-settingsalso detect the resolution is "1024 x 768",But it seemed useless using this tool. Screenshot-NVIDIA X Server Settings:

the result of xrandr:

   Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768
