I want to remote-desktop into an Amazon EC2 Ubuntu 18.04 instance with OpenGL 3.2 support, but I can't get it to work. The EC2 instance has an Nvidia T4 card.

lspci:
3D controller: NVIDIA Corporation TU104GL [Tesla T4] (rev a1)

nvidia-smi:
NVIDIA-SMI 450.142.00 Driver Version: 450.142.00 CUDA Version: 11.0

This driver supports OpenGL 4.6

For remote desktop, I use vnc4server and cinnamon. My ~/.vnc/xstartup:

#!/bin/sh
cinnamon-session &

The problem: in a VNC / cinnamon session, the OpenGL support drops all the way to 1.3:

glxinfo (in VNC / cinnamon terminal):
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.3 Mesa 4.0

Is there any remote desktop software / Linux GUI combination that will support at least OpenGL 3.2 in a remote session on a Ubuntu 18.04 Nvidia Tesla 4 machine?
