Grin-Miner not activating GPUs

Managed to setup Grin node, wallet etc… (Debian 9) just as described in the getting started tutorial. I cannot get grin-miner to properly use my 1080tis. When I connect to grin-pool I get:

Connection Status: Connected to Grin [etc…]
Mining Status: Starting miner and awaiting first graph time

The console shows two cuckatoo_mean_cuda plugins (same issues happen with cuckaroo) with the same device ID number. My config file specifies two different device names. Nvidia-smi says that neither of my cards is being used so it feels like the miner cannor activate my GPUs. For the record even using a config script with only one GPU gives the same exact problems.

I wonder if maybe grin-miner is attempting to launch the GPU that operates my display or something. It isn’t very clear to me how the miner chooses which GPU to operate.

#UPDATE
If I select the ocl_cuckaroo plugin my GPUs manage to mine. Why won’t the cuda specific plugins work though?

Here’s my config:

log_to_stdout = true
stdout_log_level = “Info”
log_to_file = true
file_log_level = “Debug”
log_file_path = “grin-miner.log”
log_file_append = true

run_tui = true
stratum_server_addr = “eu.stratum.grin-pool.org:3416
stratum_server_login = “MY_USER”
stratum_server_password = “MY_PASS”
stratum_server_tls_enabled = false

[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 0
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024

[[mining.miner_plugin_config]]
plugin_name = “cuckatoo_mean_cuda_gtx_31”
[mining.miner_plugin_config.parameters]
device = 1
expand = 2
cpuload = 1
ntrims = 176
genablocks = 4096
genatpb = 128
genbtpb = 128
trimtpb = 512
tailtpb = 1024
recoverblocks = 1024
recovertpb = 1024

Use this for 1080 ti, 2080, 2080ti
