Re: Very poor YouTube video stream playback on x120e with Ubuntu 12.04LTS
I have been chasing this a long time. I remember that I had no problem streaming HD 1080 video from YouTube when I was still running Win7 on my x120e: E-350 + 4GB RAM. Then I formatted and put Ubuntu on it, everything seemed fine but then I noticed video tearing when watching videos in VLC player.
After much googling, I downloaded the Catalyst driver from AMD's site and installed it. Forced reducing tearing in Catalyst, forced VLC to use hardware acceleration and the video looks much much much better now.
However, my problem now lays in stream 1080 videos in YouTube. The video lags and just looks terrible. I tried to look at the GPU usage when watching the video stream from YouTube and I believe the GPU isn't clocking itself higher to handle the video, 278 MHZ out of max of 492 MHZ. Even when streaming 720 videos I'm getting dropped frames. I tried this in both FireFox and Chrome, both with hardware acceleration enabled.
I tried to force a higher clock speed and memory speed using "aticonfig" but I think I can't force the settings because I'm a mobile video card: "ERROR - ATI Overdrive(TM) is not supported on the Default Adapter - AMD Radeon HD 6310 Graphics"
Anyone know how I can fix my video stream playback issue -OR-
How to overclock the mobile video card on Ubunut?
Thanks in advance!
