Хожу на сервер через xrdp.
Некоторые gui приложения вызывают такую ошибку:
QXcbConnection: Failed to initialize XRandr
Qt: XKEYBOARD extension not present on the X server.
The X11 connection broke: Maximum allowed requested length exceeded (code 4)
XIO: fatal IO error 2 (No such file or directory) on X server ":10.0"
after 211 requests (207 known processed) with 0 events remaining.
