Comment 3 for bug 677262

Sorry, the package flashplugin-installer worked one time but I have still the problem (notably with youtube)

To reboot my computer, I have to use the Magic SysRq Keys (see links [1], [2] and [3]) : Alt + Syst + S --> E --> I --> U --> B. I tried to use the TTYs with Ctrl + Alt + F1 (and others), but nothing changes in the display and the sound of the flash video still play in background.

I tried the full screen mode on several websites (see links [4], [5] and [6]) and the only one which doesn't work is Youtube. For this one, I had to right click on the video, then to select the parameters. In the parameters window (in the display tab) I unchecked the box "Enable hardware rendering" (French : j'ai décoché la case "Activer l'accélération matérielle").

I didn't try to deactivate the proprietary drivers, but if it works it would be a more global solution.
