X crashes on RasPi 3 with Ubuntu Mate 15.10

Hello,

First of all I want to thank the Ubuntu Mate team for this phenomenal distro that I’ve been using for a while on almost all my laptops. Now, to the problem - I got the new Pi3 and installed a fresh new Ubuntu Mate 15.10 on it. After it boots and I go to install an application from the boutique X completely crashes and brings me to the console screen. I can run “startx” and it loads again. After I login back the LAN and Wifi connections disappear and can’t seem to enable them back. I have tried with two 1A and 2A power supplies and have reinstalled the SD card three times already.

Anyone anyone this issue?
