Mate via NICE DCV?

0

Hi AWS gurus, I have a working TigerVNC setup on a G4 with an Nvidia GPU, and I have a graphics-based application that can discover and use the GPU successfully. That is to say, my desktop environment (/usr/bin/mate-session) is working and the GPU drivers are as well. I'm trying to upgrade to NICE DCV but I can't find resources on using anything but Gnome 3 and X11. I think the X11 requirement is fine, as it's ostensibly what I'm using for TigerVNC, but I would prefer to stick with Mate. I've tried sudo dcv create-session --type console --owner ubuntu --init /usr/bin/mate-session test-session but it doesn't work. If I just create a default console session, the DCV Client hangs (spinny wheel) after authentication success. What am I missing?

Ensure that your Ubuntu is at graphical.target runlevel and that dcv is in video group. Download the packages from https://www.nice-dcv.com/ and install the necessary packages

tar -xvzf nice-dcv-ubuntu*.tgz && cd nice-dcv-*-x86_64
sudo apt-get install -q -y ./nice-dcv-server_*.deb
sudo apt-get install -q -y ./nice-dcv-web-viewer_*.deb
sudo usermod -aG video dcv
sudo apt-get install -q -y ./nice-xdcv_*.deb
sudo sed -i "s/^#enable-quic-frontend=true/enable-quic-frontend=true/g" /etc/dcv/dcv.conf
sudo systemctl isolate graphical.target
sudo systemctl restart dcvserver

Create a console session (sudo dcv create-session --type console --owner ubuntu) and try connecting.

If this doe not work, NICE DCV may not support Mate console session. You can try virtual session if console session does not work.

Create a virtual session sudo /usr/bin/dcv create-session ubuntu --owner ubuntu --storage-root /home/ubuntu

    Thank you very much for the response. tl;dr Mate not supported.

    For anyone else, looks like MATE uses lightDM (rather than Gnome3's GDM) for display management backend. In prelims for NICE DCV install docs, says incompat. with lightDM.

    Oof b/c Gnome is a resource monster but +1 for NICE docs & +1 for community support. Thx again.
