Error starting GDM with your graphics card: 01:00.0.0
1. Open DriveDroid app. Go to USB Settings.
2. In USB System, set to Standard Android
3. In Automatic USB Mode etc, set it to Media Transfer Protocol. The MTP + Android Debugging simply enables the use of ADB at the same time as MTP.
With these settings, for me, I am able to mount all 3 types of devices. (Read-only USB device, Read-Writable USB device and CD-ROM device.
See if my settings work for your device.
Good luck mate.
