I tried using Fn+<- to turn the brightness down, and it showed the little sun icon indicating the brightness was turning down, but it didn't do anything.
I also tried xbacklight -set 100 but that didn't do anything either.
I recently installed Ubuntu 9.04 (x64) on my gateway m-series laptop. Works great minus the fact that I can adjust the screen brightness. when using an applet or my keyboard, ubuntu shows that it is being adjusted, but the actually screen brightness is constant(100%). Besides the fact that it is killing my battery, my eyes dont really adjust well to it.
hey, i'm trying to reduce brightness on my screen because it is currently stuck at 100% from day 1 of ubuntu use. I have FN + F keys to adjust brightness but they don't work, that was a given. I tried xbacklight but when I set the brightness either by directly setting or reducing it dosen't do...
I have a gateway m-series laptop, and I just recently installed ubuntu 9.04 (x64) in attempts to broadening my OS use. For the most part this is working great, but my current issue is with my screen brightness. When attempting to adjust the brightness either through ubuntu or on my keyboard(fn+up or down) ubuntu shows that I am adjusting the brightness but there is no actual change.
Definitely a laptop problem, hopefully not a hardware problem.
When I try to adjust my laptops screen brightness, it goes to some very low brightness and then the screen starts flickering (ie changing between different brightness levels). When my laptop boots, it's at full brightness, and when I adjust that, flickering starts. After that I cannot get it back to any non-very-low brightness.
Hello! I have just installed Ubuntu 12.10 on my Acer Aspire One 725 but I cannot seem to adjust my screen brightness and it is stuck on maxmimum draining my battery quickly. I have searched through every thread but nothing seems to work for my specific laptop. I have tried editing my
as tried in many other threads but it has not worked for me.
I can not adjust the screen brightness on my HP Pavillion Dv3-2154ca, using Ubuntu 11.10. My Fn-f7/f8 keys don't work (they just show a changing screen brightness bar, with no effect), and adjusting 'screen brightness' does nothing as well.
I'm new to Ubuntu/Linux, so simple answers would be much appreciated!
I have an Acer Aspire one 5742 laptop. I installed Linux Ubuntu 12.10 on it. I have one problem with it. no matter how I press the Fn+ up or Fn + down keys I cannot adjust the Screen Brightness. It is at its maximum brightness and this drains the laptop battery. I did some googling and found out that you needed to change some settings in the grub file but I don't know exactly what to do.
