[BUG] - Doesnt launch properly on archlinux

[cytoplasmoid]

R2modman fails to launch at all ( tried appimage, tar.gz, binary from aur)

Outputs the following message if run from command prompt:

$ r2modman
starting server on /tmp/app.r2mm
starting TLS server false
starting server as Unix || Windows Socket
[7607:0415/181006.354307:FATAL:gpu_data_manager_impl_private.cc(445)] GPU process isn't usable. Goodbye.
Trace/breakpoint trap (core dumped)

Steps to reproduce the behavior:
Download appimage from the releases page
Set as executable
Run

Expected behavior:
App opens and functions

Screenshots:

Opens like this for about 2 seconds before closing ^

Additional context: Running up to date archlinux, nvidia 1070 card
