Did you use krandrtray or xrandr? Please try "xrandr -q --verbose" and then switch through all available modes

# xrandr --output DVI1 --mode 0x45
# xrandr --output DVI1 --mode 0x44
# xrandr --output DVI1 --mode 0x46
...

In my case, for instance mode 0x49 (1024x768@85Hz) doesn't work. But this mode is chosen by xrandr when no explicit refresh rate is given. With xrandr I could successfully revert to the previous (working) mode by blindly using the bash history.

Assumptions:
- Maybe that krandrtray (which I used for nearly all previous tests) also choses 85Hz for 1024x768 regardless of the refresh rate which is actually selected by the user.

- Maybe that krandrtray has a bug in the "restore to the previous mode" function.

Could you please check this?
