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.

I'm not sure how you're adjusting the brightness, but using
xrandr
, may yield different results.As in
xrandr --output VGA-0 --brightness 1.1
or0.8
for darker, etc (seexrandr
's output for your output name, maybe HDMI-0 or so)[Q showed up in "Unanswered Questions", may help someone with a different brightness option. Probably will never get a reply from @Maverick Snyder though, last seen in 2013]
