I have installed Xserver using these commands
sudo apt-get install xauth
sudo apt-get install xorg
Even I have installed nautilus. I have installed xming on my windows 10 mcahine. Now when using putting and xming and running the command startx I am getting a graphical window, which doesn't look good and too slow. What I read is that xming uses the client graphics driver opnegl and not server driver and it should be quite fast. What I am missing here. Do I need to install lightdm or GDM on ubuntu.
Another question is if I install
sudo apt-get install ubuntu-desktop
Will the server boot into graphical environment, which I don't want. I just want to access the remote ubuntu 14.04 server graphically and when session is terminated it just remains as a headless server.
You can try x2go. It's basically allows you to run remote X session:
