Subject: Keys do not release when using Emacs in X2GO Client

Date: Mon, 28 Jan 2019 13:56:23 +0800

[Message part 1 (text/plain, inline)]

Package: x2goclient
Version: 4.1.2.0

I am using Emacs 24.5.1 with x2go client version 4.1.2.0 in Windows 10. My
server OS is Ubuntu 16.04 and the x2goserver comes from the PPA repo.

The problem happens if I hit "ctrl+space" to start mark region in Emacs and
then press down "ctrl+n" to scroll down the region for a few seconds.
Usually after I release "ctrl+n", Emacs will leave the currently marked
region for further commands. But in the reported version of client, Emacs
keeps scrolling down until it reaches the end of the file. There is no way
to stop it within Emacs (e.g., "ctrl+g").

I have tried to move the cursor by keeping "ctrl+n" pressed down. This
issue does not happen after I release the key.

This issue happens when the session type is either "XFCE" or "published
application". I have not tested other session types as I do not have an
environment for that. And client version 4.1.1.1 does not seem to have this
issue.

Thanks and regards,
Yan

I do not get the difference between this and the description above.
Please explain!

Please run "xev -event keyboard" inside the session and check if you
see all the KeyPress and KeyRelease events for you keys. If anyone is
missing this could explain your issue.

The difference is whether I start mark region (by hitting "ctrl+space")
before moving cursor. The client will only stuck if I first start mark
region and then hold cursor-moving keys like "ctrl+n" or "ctrl+p" for a few
seconds.

 I tried "xev -event keyboard" in a XFCE session and did not observe any
missing keystrokes.

You could try updating your nx-libs to nightly and retry:

Ok, understood. But still not replicable for me.

Nor did I. So maybe this is bug in emacs. I tested with 24.3.1, can
you downgrade?

Just a thought - there is some lag in the screen updates from the remote
host when using a protocol like x2.  It is possible that holding the keys
for a few seconds, with auto-repeat, has buffered enough copies of the
keystroke to scroll the file all the way to the end, even after you let
go.  Is that possible?

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.

Well, just for note, from time to time I observe similar behavior even
without NX - when switching between apps with Alt-TAB - TAB key is
occasionally not released.
Looks like some bug either in kernel, or in Xorg, not sure where exactly.

Hi Uli,

I found a temporary solution. If I disable the transient mark mode, under
which the selected region is highlighted, this issue goes away. So I guess
the issue is related to events generated by rendering the highlighted
region. And one thing I forgot to mention is that if I start emacs without
GUI (i.e., emacs -nw), I do not have this issue.

On the other hand, I have tried to use ADSL/ISDN, change my emacs version
to both 26.1 and 24.3.1, and upgrade NX to the nightly build. None of these
has any effect.

Thanks and regards,
Yan

So this indicates that it probalby is connected to drawing. If this
happens via images for some reason it might explain the problem.

Please perform this test for me: Edit /etc/x2go/agent.options on the
server and ensure that the following line is active (no leading '#'):

X2GO_NXAGENT_DEFAULT_OPTIONS+=" -extension GLX"

Then start a new session (with transient mark mode enabled) and retry.
Is that working better?

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.

I may have found a hint of the root cause of this bug (tested with emacs 27.1).
I believe that it is related to clipboard updating. If I disable clipboard updating from emacs the stuck key behavior goes away.
Note that for every line that we widen the selection in emacs the clipboard is automatically updated. (I proved this by repeatedly pressing ctrl-v in notepadwhile emacs exhibited the stuck key behavior and each time the pasted text grew.)
If it turns out that emacs and/or x2go prioritizes clipboard updates before key-up events we may end up in a race where the clipboard takes longer to update than it takes emacs to scroll the cursor one line and enlarge the clipboard even further.
To play around with this you can redefine the gui-set-selection function as a nop in emacs to disable the updating. (This is not a workaround though since it completely disables copying from an emacs window. A better work-around may be to add some sort of rate-limit to this function but I haven't played around with that yet.)
(defun gui-set-selection (type data))

Hi,

I observed the bug described in this thread and did some experiments with Uli Sibiller.

- X2GoClient V. 4.1.2.2
Additional X-Servers on Client
- VcXsrv 1.20.6.0
- VcXsrv 1.20.9.0
- MobaXterm 21.1.0.4628

Server:
- Centos 7
- nxagent-3.5.99.26-1.el7.x86_64  (and also an experimental version nx-3.5.99-sc36clipboard3)
- x2goserver-4.1.0.3-9.el7.x86_64
- x2goagent-4.1.0.3-9.el7.x86_64
- x2goserver-common-4.1.0.3-9.el7.noarch
- x2goserver-xsession-4.1.0.3-9.el7.noarch

X2go Session: application, terminal emulator (konsole), X-server with option -multiwindow

We tried various combinations of parameters and program versions. Findings:

- The problem only occurs with VcXserv (all versions, the one integrated in X2GoClient as well as two stand alone versions). With the X-server provided by MobaXterm (%USERPROFILE%\Documents\MobaXterm\slash\bin\XWin_MobaX.exe) everything in fine.

- The problem depends on the following VcXserv  command line options:
   + option "-r": it turns of keyboard auto-repeat. If auto-repeat is off, the problem does not occur
   + option "-clipboard": without this option, the problem does not occur
   + option "-noprimary": with this option, the problem does not occur

So adding "-noprimary" to the VcXserv options or using XWin_MobaX.exe seems to be the way to go for now.

Subject: Keys do not release when using Emacs in X2GO Client

Date: Wed, 22 Nov 2023 07:56:00 -0800

I also hit this problem in x2go 4.1.2.2.  emacs version on Linux is 26.3 
but I doubt that matters.

What I did to get past it is run x2goclient.debug.exe instead of 
x2goclient.exe on the windows side.
