The latest upgrade worked for a day, then I loaded some updates and the screens disappeared. I couldn't fix GDM so I downloaded the XFCE desktop which runs, but I still have to go through CLI and tty to get the system up and running. Prior to that, I could not connect wirelessly and still cannot. Oh well.
You guys should have stayed with Debian stable branch. In fact, stick with original Mint. I downloaded 13 Mate edition the other day and it is a gem! Also, the guy running SolousOS (I think he worked for you guys) has a great Debian OS there. I've been tinkering with that the past month and it is awesome.
I hope you guys fix your Debian issues. I think I'll have to pass though, sorry....too many bugs here.
