I'm playing around with Proxmox2 to see if I can use it as a Workstation OS.So far so good.I installed Proxmox2 on my Workstation's SSDrive and then did apt-get install gnome.Desktop installation went well.I had to edit /etc/pam.d/gdm3 file and comment out the 4th "auth" line that prevented root login with GUI.After that I had GUI in use.Now if I could only get my new ATI card to work with dual display. No luck so far.
