View Full Version : [ubuntu] Glitches

August 24th, 2009, 12:43 PM
I'm using an acer aspire 5738z and have installed both win xp and ubuntu 9.04 desktop to it. I'm not able to decrease the screen brightness and the volume is not as high as windows. Whenever i press the hotkeys to decrease the brightness, the display brightness shows up and appears to decrease the bightness. But then reverts to normal. Is there anything that i can do to solve this problem...??? My battery backup get reduced by half due to the screen because of this.

My screen tft is the same. I cannot find any proper driver for the monitor so I guess that's why. Webpages very bright (headaches) and the brightness keeps reverting.

I clicked System, preferences, display

Got a mesage saying do you want to use vendor tool?.
Clicked yes.
Nvidia panel comes up (should do same for ati).
Adjust brightness there.
That seems to work.
So try changing using the vendor tool if you have a graphics card.

I have also read something about reducing gamma somewhere, which might help.
