I'm very new here and in fact coming from (K)ubuntu. I have got a notebook with a 1,3ghz SU7300 core2duo, 4gigs of RAM and an Intel GMA 4500MHD and have gone for LMDE12 32bit.
Unfortunately I'm having trouble with the video playback performance.. On Ubuntu I had no trouble whatsoever playing back 720p videos on both Youtube and VLC. On LMDE it is impossible to watch a 720p Youtube video. It runs with less than 5FPS. Watching a 720p video on VLC is possible and runs smooth, but any action on the X server (minimizing a window, switching to another window, or loading a webpage in the background) makes the playback stumble.
I tried using the nonfree flash player instead of the one that came with Mint. No luck.
I feel that Ubuntu utilized my graphics card to render videos, even youtube, thus making the playback rock-stable, and LMDE doesn't.
I'm quite bummed because I've absolutely fallen in love with the Cinnamon Desktop.. is there a way to check about the hardware acceleration or the graphic card driver? Any hint is appreciated.
