SUMMARY
When trying to connect to my computer (running Wayland KDE with an NVIDIA
graphics card), the client connects, shows a black screen for fraction of a
second and the connection gets interrupted. When trying to use krdpserver
manually, the following errors appear
```

```
The first error to appear in the log is "ERRINFO_GRAPHICS_SUBSYSTEM_FAILED
(0x0000112F):The server-side graphics subsystem is in an error state and unable
to continue graphics encoding.".
According to the README available in KRdp's GitLab
(https://invent.kde.org/plasma/krdp), "[...] hardware encoding on NVidia
hardware can not be used and software encoding will be used instead.", however
it doesn't seem that software encoding is working, since a warning from KRdp
says "Client does not support H.264 in YUV420 mode!"
STEPS TO REPRODUCE
1. Start KRdp using the command krdpserver -u user -p password
2. Try to connect with an RDP client (example used: Microsoft's Windows App,
other alternatives also fail)
