I am a beginner running linux on my A1. I am having problems with playing youtube videos on full screen. THey are VERY choppy, but in the smaller screen/window size on the youtube site they play ok. Its just when i select full screen that the video gets very choppy. I have done lots of reading and searching but i have not read of a fix for this that i understand. I am a complete Linux beginner. I have increased the firefox cache to 400MB, i doesnt seen to have helped much. I have disabled all power saving modes but it will not let me select "performance mode". It allows me to select it and apply but it doesnt keep the setting. When i close the power saver screen and then reopen it, it is back on the "balanced" mode. I really would like to play youtube in full screen with the same smoothness of motion that i get in small or standard youtube mode. kind regards kev
