Subject: Re: [X2Go-Dev] Bug#475: remote UI?
To: Michael DePaulo <mikedep333@gmail.com>, 475@bugs.x2go.org, x2go-dev@lists.berlios.de
Content-Type: text/plain; charset=UTF-8
By "remote UI" I mean UI components rendered in X window, created by x2goclient.
Remote desktop manages to draw only gnome-panel and sometimes keychain
password input dialog.
After that only few elements on panel are "click-able" but no new
windows/dialogs are shown.

I suspect the issue is related to keyboard mapping changes for OSX in
4.0.2.0, because:
a) x2goagent's strace is constatnly flooded with something like this:
write(39, "xkb_keymap \"default\" {\nxkb_keyco"..., 4096) = 4096
write(39, " <I6B> = 235;\n     <I6C> = 236;\n"..., 4096) = 4096
write(39, "      modifiers= RAlt;\n        m"..., 4096) = 4096
write(39, "     map[Shift+Lock+LevelThree+L"..., 4096) = 4096
write(39, "l_name[Level3]= \"Alt Base\";\n    "..., 4096) = 4096
write(39, "l) {\n        repeat= True;\n     "..., 4096) = 4096
write(39, "fee9+AnyOfOrNone(all) {\n        "..., 4096) = 4096
write(39, "       action= SwitchScreen(scre"..., 4096) = 4096
write(39, "roup2]= [            0xe7,      "..., 4096) = 4096
write(39, "6c,            0x4c ],\n        s"..., 4096) = 4096
write(39, " ] };\n    key <KPEQ> {         ["..., 4096) = 4096
write(39, "RM\",   1 },\n                { <A"..., 4096) = 4096
write(39, "top=  20;\n            left= 1;\n "..., 2530) = 2530
close(39)
b) ltrace flooded with keyboard related strcmp() calls like following:
__fprintf_chk(0x232f310, 1, 0x810282, 0x7fcb39, 0xb22878)

    = 17
strncmp("MDSWESC", "AB04AB05AB06AB07AB08AB09AB10RTSH"..., 4)
