I am using Mint 13 Mate 64bit. I like to watch youtube videos such as nascar races ect. The problem that I am running into is, that when I go fullscreen, flash will play for a minute or two, then the display will suddenly freeze but sound will continue for another few seconds. After that, sound stops and the whole system is frozen, mouse and all. I have to press and hold the power button to get out of it. I also have windows 7 installed on this computer and it works fine on that side. I have an Acer laptop and have downloaded the driver for my radeon hd 4200 video card. All is fine until I try to use flash. Pulling my hair out on this one and I don't really have all that much to spare if you know what I mean! Can someone help/walk me through this problem?
