I have an Ubuntu 14.04.2 server install to which I have added Unity (sudo apt-get install --no-install-recommends ubuntu-desktop) so that I can get a couple terminals on the monitor. I'm seeing a number of errors in the syslog/dmesg and not getting anything to display.
The same machine boots Fedora20 and Windows2012 (different partitions on the same HDD) fine. Can anyone point me in a direction to fix this?
