I have Intel GM45 GPU running on standard mesa drivers and xorg.I noticed that since about a week (I do regular daily updates), I no longer have video in mplayer after the system has been suspended and then resumed.
I just installed smplayer and it's not working! I don't seem to recognise the reason, but it might be something in the lines of 'unrecognised mplayer version' or something. Although, mplayer works. from terminal i'm able to run mplayer and watch movies.
