$ go get -u code.dumpstack.io/tools/appvm
## Generate resolution
By default uses 1920x1080. If you need to regenerate `appvm/nix/monitor.nix`:
$ $GOPATH/src/code.dumpstack.io/tools/appvm/generate-resolution.sh 3840 2160 > $GOPATH/src/code.dumpstack.io/tools/appvm/nix/monitor.nix
Autodetection is a bash-spaghetti, so you need to check results. BTW it's just a X.org monitor section.
## Run application
$ appvm start chromium --verbose
