Description (last modified by Antoine Martin)

Windows 10 (17362.320) client to Ubuntu 16.04.5 LTS server

During an otherwise-normal working xpra shadow session, I get:

2018-11-05 21:15:05,781 client @26.140 server is OK again

2018-11-05 21:34:21,066 client @41.420 window-close event on desktop or shadow window, disconnecting

The only thing I remember not working, is that after some time, I couldn't change the language. Layouts are (en-us, el-gr), and I remember en-us --> el-gr transition working (on both computers), and then failing to do so on the shadowed server (client host switched normally)

The "special" keystrokes that I might have used (non-inclusive) are:

  • Ctrl+Alt(+Shift)+Arrows
  • WinKey(+Shift)+W
  • Alt+Shift (on both computers, is the language-changing shortcut)

The handling of modifier keys for shadow sessions probably needs more work.

The only thing I remember not working, is that after some time, I couldn't change the language.

What do you mean by "change the language"?

Layouts are (en-us, el-gr), and I remember en-us --> el-gr transition working (on both computers), and then failing to do so on the shadowed server (client host switched normally)

How do you "transition"?
