On my system I will use VNC to login. But at this time, after connect to the pc, I get the automatic login with unity desktop. What I have to do, to have gnome desktop on VNC connection instead of unity?
It should be sufficient to create a suitable
~/.vnc/xstartup file in your account on the remote host, including the line
gnome-session --session=your-preferred-session &
For example, a minimal file for a gnome-classic session might be
#!/bin/sh #Uncommment this line if using Gnome and your keyboard mappings are incorrect. #export XKL_XMODMAP_DISABLE=1 # Load X resources (if any) if [ -r "$HOME/.Xresources" ] then xrdb "$HOME/.Xresources" fi gnome-session --session=gnome-classic &
The text of your-preferred-session will depend on what desktop packages you have installed - which you can check by looking in the /usr/share/xsessions directory i.e.
$ ls /usr/share/xsessions/ awesome.desktop gnome-classic.desktop gnome-fallback.desktop gnome.desktop gnome-shell.desktop ubuntu-2d.desktop xfce.desktop
xstartup file can also be used to start non-gnome desktop sessions, for example
if which startxfce4 > /dev/null; then exec startxfce4 fi
--replace in xstartup with the session you want to use. It works on Fedora.
