VNCServer and cinnamon and plasma-desktop 5 problem Fallback mode

Question

Hi,
I tried to use vncserver (tigervnc) on arch with cinnamon or plasma-desktop but when I connect remotely on the machine I get a black screen with cinnamon-session-cinnamon.
and with cinnamon-session-cinnamon-2d I enter in fallback mode. With xfce it's working.
Can someone help me ??
Thanks,
Dominique

Answer 1

Xvnc only provides software OpenGL, but Cinnamon (and Gnome Shell, and Ubuntu Unity) requires hardware OpenGL. So it's normal that only fallback mode works. Running these environments in Xvnc will be possible with the next release of VirtualGL.
Edit: plasma-desktop should work, but not in opengl mode, only in xrender mode or with compositing completely disabled.
