### GUI doesn't start
This most likely means your device lacks either a working DRI driver (check if a `/dev/dri/card*` device exists) or an OpenGL ES 2.0 driver (even a software one).
This most likely means your device lacks either a working DRI driver (check if a `/dev/dri/card*` device exists) or an OpenGL ES 2.0 driver (even a software one) or that your user account lacks permission to open /dev/dri devices.
The error message from Qt may give you a hint as to what the problem is. You may try adding `-platform linuxfb` to the end of the `moonlight-qt` command (which will somewhat break the UI, but may allow you to get far enough to stream) or try creating a EGLFS configuration json file [as detailed here](https://doc.qt.io/qt-5/embedded-linux.html#eglfs-with-the-eglfs-kms-backend).
If you see an error like `Could not open DRM device /dev/dri/card0 (Permission denied)`, it's probably your account is not a member of the `video` group. To fix this, run `sudo usermod -a -G video $USER` and reboot.
### Input devices aren't working
This is probably because you're not a member of the `input` group, so Moonlight lacks permission to open input devices to receive input.
To fix this, run `sudo usermod -a -G input $USER` and reboot.
### GUI is very slow/unresponsive
This is usually because your device or distro lacks an hardware accelerated OpenGL ES driver and is using software rendering instead. Unfortunately, this is quite common on many ARM devices due to the lack of open-source drivers. You may try to find a distro that contains proper OpenGL ES drivers, or you can try adding `-platform linuxfb` to the `moonlight-qt` command (which will cause some UI issues, but should make it slightly faster).
