See also this post on the x2go mailing list https://lists.berlios.de/pipermail/x2go-user/2012-November/001123.html There, Michael had the same problem I observe with: Server Side: Ubuntu 12.04 with x2goserver 3.1.1.6-0~610~precise1 from the stable PPA Client Side: Mac OS X 10.6.8 with x2goclient 3.99.2.1 from the x2go website Keyboard Layout: en_us everywhere, and in x2goclient I checked "Keep current keyboard Settings" I'm using Mac OS X 10.8.2, XQuarz 2.7.4 and also x2goclient 3.99.2.1. I also tried changing x2goserver from stable PPA to 4.1.0 from git. Also toggling "Keep current keyboard Settings" does not make a difference. Server is also a ubuntu machine, but could cross-check this with a Debian install (and see if the same error occurs there). The problem is that keystate changes while it is transferred to the host: MAC: state 0x0, keycode 26 (keysym 0x31, 1), same_screen YES, LINUX: state 0x10, keycode 26 (keysym 0x65, e), same_screen YES, This makes the keyboard unusable, since every client keycode gives a wrong keysym on the host. The mask 0x10 is set for all key events sent to the host, every time. Looking around in X's headers I found: defined in /* Key masks. Used as modifiers to GrabButton and GrabKey, results of QueryPointer, state in various key-, mouse-, and button-related events. */ #define ShiftMask (1<<0) #define LockMask (1<<1) #define ControlMask (1<<2) #define Mod1Mask (1<<3) #define Mod2Mask (1<<4) #define Mod3Mask (1<<5) #define Mod4Mask (1<<6) #define Mod5Mask (1<<7) So keystate 0x10 means the keyevent has Mod2Mask set. defined in (but don't think it's a standard X11 header) #define AltMask Mod1Mask #define NumLockMask Mod2Mask #define AltLangMask Mod3Mask #define KanaMask Mod4Mask #define ScrollLockMask Mod5Mask Which appears to be a NumLockMask. This makes sense since 'dfg' gives the numbers '124', i.e. indicating that I have some sort of Numpad overlay in the middle of the keyboard on the host. For what is worth, a found similar bug report with no machines remote desktop. http://apple.stackexchange.com/questions/31691/no-machine-remote-desktop-issue "For instance, the Delete key was now comma, all the letters were transposed, general chaos. " I can also confirm that backspace is comma, so this seems to be the same NumLockMask problem. Every key is garbled, but not randomly. The same problems apparently appears here in a bug report in XQuartz. They think its not their fault: http://xquartz.macosforge.org/trac/ticket/471 Quote: "From my experience using NX in Linux, NX is badly designed.

I can supply further information for the mac os x keyboard bug in= x2go. I think I had this problem already ~2 years ago, when I first tried = out x2go. All pressed client keys produce wrong key events on the host. Its= a real show-stopper since it makes x2go basically totally unusable for me = and others.

There, Michael had the same problem I observe with:

=
Server Side: Ubuntu 12.04 with x2goserver 3.1.1.6-0~610~precise1 = from the stable PPA
Client Side: Mac OS X 10.6.8 with x2goclient 3.99.2.1 from the x2= go website
Keyboard Layout: en_us everywhere, and in x2goclient I checked &q= uot;Keep current keyboard Settings"

I'm using Mac OS X 10.8.2, = XQuarz 2.7.4 and also x2goclient 3.99.2.1. I also tried changing x2goserver= from stable PPA to 4.1.0 from git. Also toggling "Keep current keyboa= rd Settings" does not make a difference. Server is also a ubuntu machi= ne, but could cross-check this with a Debian install (and see if the same e= rror occurs there).

The problem is that keystate ch= anges while it is transferred to the host:

MAC: =C2=A0 state 0x0, keycode = 26 (keysym 0x31, 1), same_screen YES,
LINUX: state 0x10, keycode 26 (keysym 0x65, e), same_screen YES,<= /span>

This makes the keyboard unusabl= e, since every client keycode gives a wrong keysym on the host. The mask 0x= 10 is set for all key events sent to the host, every time.

Looking around in X's heade= rs I found:

defined in <X.h>
/* Key masks. Used as modifiers to GrabButton and GrabKey, result= s of QueryPointer,
=C2=A0 =C2=A0state in various key-, mouse-, and button-related ev= ents. */
#define ShiftMask =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 (1<<0)
#define LockMask =C2=A0 = =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0(1<<1)<= /div>
#define ControlMask =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 (1<<2)
#define Mod1Mask =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0= =C2=A0(1<<3)
#define Mod2Mask =C2=A0 = =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0(1<<4)<= /div>
#define Mod3Mask =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 = =C2=A0 =C2=A0(1<<5)
#define Mod4Mask =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0= =C2=A0(1<<6)
#define Mod5Mask =C2=A0 = =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0(1<<7)<= /div>

So keystate 0x10 means the keyevent has Mod2M= ask set.

defined in <xorg/atKeynames.= h> (but don't think it's a standard X11 header)
#define AltMask =C2=A0 =C2=A0 =C2=A0 =C2=A0 Mod1Mask
#define NumLockMask =C2= =A0 =C2=A0 Mod2Mask
#define AltLangMask =C2=A0= =C2=A0 Mod3Mask
#define KanaMask =C2=A0 =C2=A0 =C2=A0 =C2=A0Mod4Mask
#define ScrollLockMask = =C2=A0Mod5Mask

Which appears to be a NumLockMask. This makes= sense since 'dfg' gives the numbers '124', i.e. indicating= that I have some sort of Numpad overlay in the middle of the keyboard on t= he host. =C2=A0

For what is worth, a found simi= lar bug report with no machines remote desktop. http://appl= e.stackexchange.com/questions/31691/no-machine-remote-desktop-issue

=C2=A0"For instance, the D= elete key was now comma, all the letters were transposed, general chaos. &q= uot;

I can also confirm that backspa= ce is comma, so this seems to be the same NumLockMask problem. Every key is= garbled, but not randomly.

The same problems=C2=A0apparent= ly=C2=A0appears here in a bug report in XQuartz. They think its not their f= ault:

If someone could point me in th= e right direction, I would be glad to help.=C2=A0
And as I have no need for the Mod2Mask, as a temporary fix, I wou= ld be fine to ignore this mask on the server side and hard code xkey->st= ate &=3D ~(1u << 4); somewhere.

Has someone an idea how to furt= her investigate this issue? Is there someone who can report a working keybo= ard with Mac Os X as client?
