Hope this is the correct forum for this ... Just thought I would post this for any possible interest and info. Yesterday I was playing a Quicktime video using VLC Media Player and for some unknown reason I decided to experiment with Compiz at the same time. I started fusion-icon and then selected Compiz as window manager. The video playing in the VLC window looked strange and jumpy so, again, for some unknown reason I decided to minimize the VLC window. The entire system locked up and I had to use the power button to shut down. When I restarted I got the usual Acer splash screen and then a black screen with the mouse pointer, and that's as far as it would go. I could not figure out how to get past that. I probably would have had to restore back to the factory configuration, BUT, as luck would have it just a short time earlier I had imaged my 8 GB SSD using PING as discussed on this page: [url="http://www.aspireoneuser.com/forum/viewtopic.php?f=39&t=3182&start=30"]viewtopic.php?f=39&t=3182&start=30[/url] Within 10 minutes I was back up and in operation thanks to the PING image, but this could have been a real pain since I have lots of customizations and software installed. So ... just beware that video and Compiz may be a bad mix. Any thoughts on this would be appreciated.
