Game Input MultipleXer

There is an instruction on how to make GIMX autorun without GUI:
Simply create a file /etc/systemd/system/gms.service (as root):

sudo nano /etc/systemd/system/gimx.service
With the following contents:

[Unit]
Description=GIMX
After=syslog.target network.target

[Service]
User=pi
Type=simple
# Replace /dev/ttyUSB0 with /dev/ttyAMA0 when using the on-board UART interface
ExecStart=/usr/bin/gimp -p /dev/ttyUSB0 -c LogitechDrivingForceGT_G29.xml --nograb
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target
Replace ttyUSB0 with your device (/dev/ttyacm



I need the opposite with GUI. Help me fix this

Just put gimx-launcher to autorun then

I'm a noob and I don't know how to prescribe it. Help if it's not difficult
