To change the keyboard shortcuts therefore perform this copy and afterwards change it. What it does not mention that if this local config copy is not made, the default configuration will be used. The archlinux mentions that for openbox configuration you need to copy the default config files to the a config folder within the home directory. The groovymame binary somehow needs a window manager for input control in mame. The window manager openbox is used in this install (september 2020). Virtual Desktops are switched on button shortcuts A restart will put the GPU available again. This command will disable the GPU in runtime. Changing XX with previous Bus ID values.Įcho 1 | sudo tee /sys/bus/pci/devices/0000:XX:XX.X/remove Now, you can disable temporally this GPU assigning the value 1 in a file called “remove” inside the correct path of this PCI device. ![]() XX:XX.X VGA compatible controller: NVIDIA Corporation Device 1b80 (rev a1) You could also try to deactivate the not needed GPU in runtime, as described at įirst, look for Bus ID of the graphic card. For example in BIOS / UEFI or by pulling the card out. If you have 2 graphical processing units (GPU), please disable the unused one. GroovyArcade splash screen shows up but frontend seems to crash
