[X2Go-Dev] Bug#1369: Bug#1369: Bug#1369: Keys do not release when using Emacs in X2GO Client

[Yan Zhang]

Hi Uli,

Sorry for the slow reply. For my XFCE sessions, turning on "-extension GLX"
seems to solve the problem. But under "published applications" mode, the
issue is still there.

Thanks and regards,
Yan

You mean NX, I guess, not X2 (there's no such protocol). However: I am
using NX over two chained WANs without such problems. For some time I even
used it for working on machines on the other side of the Atlantic ocean -
and it worked flawlessly.

@Yan: you could try setting the connection type to ADSL or even ISDN and
retry.
