[X2Go-User] Problem with SHIFT, Linux server, Mac client

[Marcin Żukowski]

I'm using x2go on MacOSX, connecting to a Linux server.

I'm hitting this weird behavior that after pressing SHIFT, some keys don't
work. This is quite annoying when typing.

For example, when I hold SHIFT and press SPACE, I'm getting these events
from xev (Linux - server side), and SPACE doesn't show. Note the "NoSymbol"
below.

KeyPress event, serial 285, synthetic NO, window 0x2800001,
root 0xe3, subw 0x0, time 615096810, (353,1185), root:(357,1288),
state 0x0, keycode 64 (keysym 0xffe1, Shift_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyPress event, serial 285, synthetic NO, window 0x2800001,
root 0xe3, subw 0x0, time 615097120, (353,1185), root:(357,1288),
state 0x1, *keycode 57 (keysym 0x0, NoSymbol)*, same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

Same in xterm on Mac (client side)

KeyPress event, serial 34, synthetic NO, window 0xc00001,
root 0x1d1, subw 0x0, time 615286125, (1429,933), root:(1449,976),
state 0x0, keycode 64 (keysym 0xffe1, Shift_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False

KeyPress event, serial 34, synthetic NO, window 0xc00001,
root 0x1d1, subw 0x0, time 615286693, (1429,933), root:(1449,976),
state 0x1, *keycode 57 (keysym 0x20, space)*, same_screen YES,
XLookupString gives 1 bytes: (20) " "
XmbLookupString gives 1 bytes: (20) " "
XFilterEvent returns: False


Here's what setxkbmap prints (server/Linux side)

$ setxkbmap -query -v 7
Applied rules from xorg:
rules: xorg
model: null
layout: us,pl
variant: ,
options: grp:shift_caps_toggle
Trying to build keymap using the following components:
keycodes: xfree86+aliases(qwerty)
types: complete
compat: complete
symbols: pc+us+pl:2+group(shift_caps_toggle)
geometry: pc(pc104)
rules: xorg
model: null
layout: us,pl
variant: ,
options: grp:shift_caps_toggle

Any ideas how to fix it? Thanks in advance!
