Recently I installed Ubuntu 12.04 on my Dell 1554 laptop.
I was adjusting my screen brightness when this happened :
this has become a recurring problem which is really annoying.
I also want to tell you that :
- I have installed the graphics drivers ATI/AMD FGLRX graphics driver.
- I have got my graphics driver checked by Dell.
Can anybody tell me a solution to this and moreover is anybody out there who is having the same problem?
Thanks in advance.
