I have a desktop system with Kubuntu 10.10 and Windows 7. Kubuntu used to be my main system, but in the last year I worked a lot with Windows (only used Linux on my laptop). Today I accidentally told Grub to start Kubuntu 10.10 (which is still the default OS). I soon restarted and switched back to Windows 7.
So i've recently installed Kubuntu 13.04 on my Vivobook V300 and i've just noticed a strange bug with my keyboard brightness FN keys. If I use the Brightness Down button it works as expected, however if I use the Brightness Up key it seems to scroll through 3 different brightness levels before returning to the first and repeating the process.
With Kubuntu, each time I try to start up the system, after the splash screen and the graphical screen comes into place, the screen keeps on flashing, like it is trying to redo the last process. A lot of the times when I move the mouse, it goes right back to the middle of the screen by the time one or two flashes pass by. Is there anything I can do to stop it from doing that?
