Adjusting Contrast, Brightness and Gamma on fglrx 9.5+

ATI has made a change in their fglrx catalyst drivers (9.5+) where setting the gamma in xorg.conf no longer works and is ignored when starting.

In my previous post I went over setting and making these adjustments. The previous methods for Contrast and Brightness remain. However for gamma, the only way and previously existing method is now using fglrx_xgamma.

In terminal;

fglrx_xgamma -c 0 -gamma .85

This setting will be immediately applied and also after restarting.

Xorg Memory Leak Fix for Jaunty 9.04 ATI Proprietary fglrx

Memory leak fixed on my sony vaio laptop with an HD3400 series. NOT completely, xorg will still leak over time (about 60mb over 8 hours and I think some of this memory is re-used for effects which will not increase the memory any further when opening, closing, etc). The change is DRASTIC compared to what I was seeing. Before this xorg would leak anywhere between 500-700mb over 4 hours of use.

ATI Proprietary fglrx Minimize/Maximize Fix for Jaunty 9.04

After a few weeks, a patch has been released a few days ago that fixes the fglrx lag when minimizing, maximizing or opening a window on ubuntu jaunty 9.04. The lag was severe freezing the entire desktop for 1-3 seconds, almost making desktop effects unbearable to use.

For those who would prefer to compile xorg;

Adjusting Contrast, Brightness and Gamma on Linux. ATI Proprietary Driver (fglrx).

If you have the ati driver installed correctly and have xorg setup correctly, you can easily change the brightness, contrast and gamma on linux.

I could not find anywhere on google a single search result except for setting gamma, so I post this here.

Ubuntu Jaunty: ATI Restricted Proprietary FGLRX Driver, Direct Rendering, Mobility Radeon HD Series

To start off I am no expert. I am a windows convert about a week ago now. However, I’m grabbing Linux by the horns and loving it!

The reason I am posting this is because it took me several hours to figure this out. I could not find in one place an organized concise approach. I’d imagine the experts already know this info but for the new Linux users, I can see this being helpful and also as a reference for me in the future ;)

This does not fix the current memory leak in Xorg or the slow sluggishness of compiz when minimizing, maximizing or resizing. Sadly, I’m experiencing both of these issues on Jaunty with the ATI Driver, I have not tried the open source ATI Driver yet.

I went through many installations and removals of the ati driver during this process. I will only explain how and what I did to actually get the driver working with direct rendering enabled.
