I had the same situation, first on ubuntu 20.04 and now still on ubuntu
20.10.

I have USB keyboard nad usb mouse. I am using mapping for my USB mouse
(btnx-config library) so I can map my button as keyboard keys, I was
noticing small freezes but I though it was library problem. But later I
wanted to create a simple keylogger from python keyboard library and
simple script which always when I press d it also press r in system
keyboard. When I did it many times, my computer freeze for few seconds,
even minute and this warning occurs in syslog.

Is it going to be solve in 21.04?

[Bug 1777708] Re: Desktop briefly becomes unresponsive when typing on 2 keyboards at the same time

2021-03-23 Thread Phip
I had the same log but the action was different.
Situations where I get the same messages:
- connect/disconnect my secondary keyboard
- when I press a key on the first keyboard and then I press the key on the 
second keyboard
- on same keyboard: pressing on a letter key and then using an FN key 
combination

After a while, causing a delay in the response when a key was pressed.

After some testing, I removed the "gnome-shell-extension-ubuntu-dock"
package and no longer had this problem.

To have the dock showing again, I installed the "Dash to Dock" extension
and had to disable (using Gnome Tweak Tool) the option "Use keyboard
shortcuts to activate apps" (in Behavior extension tab). With this
option enabled, messages continue to appear as normal.

With Wayland I had no problem because apparently the "Ubuntu Dock"
extension is disabled by default. When activated, I get the same problem
as the standard version of the Ubuntu installation.

2021-03-18 Thread Gignu Trattow
I recently bought the R-GO Split keyboard too and on Ubuntu 20.04 (Gnome) it 
was very laggy.
What I did to get rid of the lag was to simply switch from Gnome to KDE Plasma 
Desktop. Switching to Wayland worked too, but unfortunately, Wayland was 
causing problems with Skype and Audacity. So that's why I'm using KDE now. It 
might take some time to get used to KDE Plasma Desktop but it's a great Window 
Manager and seems to be a lot more stable than Gnome and Wayland. 

I also tried to switch to the Brasilien keyboard and commenting out
"modifier_map Mod3 { Scroll_Lock };". But it didn't work even after
restarting several times and making sure that the Brasilian keyboard was
selected. Maybe it worked with an earlier version of Ubuntu but at least
for me with Ubuntu 20.04 (Gnome) it didn't have any effect.

Hope this is helpful!

This issue still happens on Ubuntu 20.04. I use a laptop with Bluetooth
keyboard. I couldn't use media keys like volume up and down due to the
large delay. Even if I use the media keys in a single keyboard, the
delay happens.

Post #8 solution works for me. Make sure to restart after applying the
fix.

I got this too, comes out of nowhere, typing stalls for a second or two,
sometimes the keystrokes are remembered, and typed a bit later, other
times they're just dropped and i sit and look at the screen, then try
typing and the letter shows up, very annoying for a developer.

so far)

so i'll try and disable it next time i experience the bug.

Hi :)

I also have the R-Go Tools Split keyboard and is having the exact same
issue no Ubuntu 20.04. I also had the same issue on Ubuntu 18.04.

But I found a way to fix it. If I change the display server from
X11/Xorg to Wayland then the problem goes away! :D I just followed this
guide:

  https://linuxconfig.org/how-to-enable-disable-wayland-on-
ubuntu-20-04-desktop?fbclid
=IwAR1yAApu1CItCAnngvHbZgCta1WzY718qk8dqdRXJdVkclm-_xWbOFDGmAw

So my suspection is that this is a problem with the default display
server in Ubuntu.

On the Firefox issue:
https://bugzilla.mozilla.org/show_bug.cgi?id=1640535

> There is now quite a lot of input delay. Touch-typists typing with one
hand on each keyboard will easily out-pace Firefox's ability to display
what they are typing. The problem persists until Firefox is restarted.

That is exactly what's happening to me, and it looks like it's their
bug. Sorry about that!

Hey there, thanks for the discussion, it's helped me find a way around
this problem.

I also use an R-Go split keyboard. I had the input lag issue OS-wide on
Elementary OS and Pop OS. The issue disappears on Wayland.

After switching to Regolith, which uses gnome-flashback, the issue is no
longer there. There is one big exception, though: there's still the same
problem on Firefox! All other apps are doing just fine.

I wonder whether I can somehow overcome the problem on Firefox as well.
I'm no longer sure whether it's a problem in the interaction between
Firefox and Xorg or it's a Firefox-specific problem.

If disabling 'Ubuntu AppIndicators' worked for you then it was probably
bug 1849142. Please go to bug 1849142 and help to test the proposed fix
for that.

I have updated to 20.10 and can confirm disabling scroll lock workaround
is still working.

Another thing i've just realized is without this hack, there is a huge
lag during lock/unlock/login animations. Commenting scroll lock line in
/usr/share/X11/xkb/symbols/br made animations a lot better.

2020-10-16 Thread Andre_H
Same issue here with R-Go split
Interestingly I found one configuration that works, but horribly breaks other 
things:

first, have a look with xinput

$ xinput 
⎡ Virtual core pointer  id=2[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointerid=4[slave  pointer  (2)]
...
⎜   ↳ Hantick USB Keyboard Consumer Control id=20   [slave  pointer  (2)]
⎜   ↳ HID 0911:2188 Consumer Controlid=22   [slave  pointer  (2)]
⎜   ↳ HID 0911:2188 Mouse   id=24   [slave  pointer  (2)]
⎜   ↳ Hantick USB Keyboard Mouseid=25   [slave  pointer  (2)]
⎣ Virtual core keyboard id=3[master keyboard (2)]
↳ Virtual core XTEST keyboard   id=5[slave  keyboard (3)]
...
↳ Hantick USB Keyboard  id=16   [slave  keyboard (3)]
↳ HID 0911:2188 System Control  id=17   [slave  keyboard (3)]
↳ HID 0911:2188 id=18   [slave  keyboard (3)]
↳ Hantick USB Keyboard System Control   id=19   [slave  keyboard (3)]
↳ Hantick USB Keyboard Consumer Control id=21   [slave  keyboard (3)]
↳ HID 0911:2188 Consumer Controlid=23   [slave  keyboard (3)]
↳ Hantick USB Keyboard Wireless Radio Control   id=26   [slave  
keyboard (3)]


The Hantick devices as well as the 0911:2188 devices are the R-Go Split (why so 
many?)
interestingly there is a wireless radio control???
Anyway, let's create a new group

$ xinput create-master rgosplit 0
$ xinput
⎡ Virtual core pointer  id=2[master pointer  (3)]
...
⎡ rgosplit pointer  id=27   [master pointer  (28)]
⎜   ↳ rgosplit XTEST pointerid=29   [slave  pointer  (27)]
⎣ rgosplit keyboard id=28   [master keyboard (27)]
↳ rgosplit XTEST keyboard   id=30   [slave  keyboard (28)]

and now add those 0911:2188 keyboard devices to it (note that you need
to replace the numbers in the commands)

$ xinput reattach 17 28
$ xinput reattach 18 28
$ xinput reattach 23 28
$ xinput
⎡ Virtual core pointer  id=2[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointerid=4[slave  pointer  (2)]
...
⎜   ↳ Hantick USB Keyboard Consumer Control id=20   [slave  pointer  (2)]
⎜   ↳ HID 0911:2188 Consumer Controlid=22   [slave  pointer  (2)]
⎜   ↳ HID 0911:2188 Mouse   id=24   [slave  pointer  (2)]
⎜   ↳ Hantick USB Keyboard Mouseid=25   [slave  pointer  (2)]
⎣ Virtual core keyboard id=3[master keyboard (2)]
↳ Virtual core XTEST keyboard   id=5[slave  keyboard (3)]
...
↳ Hantick USB Keyboard  id=16   [slave  keyboard (3)]
↳ Hantick USB Keyboard System Control   id=19   [slave  keyboard (3)]
↳ Hantick USB Keyboard Consumer Control id=21   [slave  keyboard (3)]
↳ Hantick USB Keyboard Wireless Radio Control   id=26   [slave  
keyboard (3)]
⎡ rgosplit pointer  id=27   [master pointer  (28)]
⎜   ↳ rgosplit XTEST pointerid=29   [slave  pointer  (27)]
⎣ rgosplit keyboard id=28   [master keyboard (27)]
↳ HID 0911:2188 System Control  id=17   [slave  keyboard (28)]
↳ HID 0911:2188 id=18   [slave  keyboard (28)]
↳ HID 0911:2188 Consumer Controlid=23   [slave  keyboard (28)]
↳ rgosplit XTEST keyboard   id=30   [slave  keyboard (28)]

Now I can type with both keyboard halfs simultaneously in a gnome-terminal!
But when I switch to other applications, e.g. firefox, only one half can type...
Maybe someone can build up on this?

[Bug 1777708] Re: Desktop briefly becomes unresponsive when typing on 2 keyboards at the same time

2020-09-13 Thread Cristiano Nunes
I use Ubuntu 20.04 and I have the same problem.

A similar bug I reported here:
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1895486

After some use, I noticed a delay when using keyboard media controls
(for example: increase volume audio).

The first time I push these key Gnome hangs for a short time before
display the action on the screen.

(This problem is still happening in Ubuntu 18.04 too. Even worse some
times, the system crashes when using media keys.)

For some reason, my Gnome freezes when using Fn keys, or when I try to
use two keyboards. A friend of mine pointed to me that it occurs when
switching to a keyboard layout that has Scroll Lock enabled, so I
disabled it in the X11 keyboard layout file for my language, and it
solved the problem.

A workaround to solve the problem is:

1) Opened the keyboard layout file for my language, in my case:

sudo nano /usr/share/X11/xkb/symbols/br

2) Commented the line:

modifier_map Mod3 { Scroll_Lock };

3) Logged out and logged in again or run command setxkbmap.

These steps are specific for the Brazilian Portuguese ABNT2 Layout and
may not work for other layouts, but it can help you find a similar
solution.

2020-07-15 Thread ToniO
I'm using Ubuntu 20.04, and fixed this issue with the workaround by Wiggy boy 
 (Thanks!):
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1858#note_818548
(and I also had to enable the "Source code" source as explained here: 
https://askubuntu.com/questions/496549/error-you-must-put-some-source-uris-in-your-sources-list/857433#857433)

This bug was a bummer to find after switching to Gnome/Ubuntu (from
Xfce, a bit older version though) mostly because of the feelingly lower
input lag in the mouse. So having also gaming in mind, it was a bummer
to find out that the keyboard and the extra buttons on the mouse don't
work reasonably anymore without freezing with 100 % CPU :/

If the only drawback of this workaround affects keyboards other than
qwerty, please at least have a configurable option in settings to
disable other than qwerties and have a functional keyboard?

For anyone looking for some closure, I doubt you'll see a fix for this
anytime soon. So the best I can offer to you all is a little hack/fix
you can do yourself. You can find it in the upstream bug over at gitlab.

2019-11-20 Thread Darrar Radgrioer
One guy (Wiggy boy  Wiggy boy ) found a fix:

from:

https://gitlab.gnome.org/GNOME/gnome-shell/issues/1858

I'm trying out some stuff on Ubuntu 19.10 right now actually.
If you wanna help me or guide me I'd be more than happy to receive your help.
Send me an email REMOVED .
EDIT:
I think I've got this working actually. So I thought it'd be writing down in 
case someone else comes around wanting to duplicate it (perhaps those over at 
the Ubuntu Bug Report Forums). Be aware though, I JUST have it working now and 
have no idea if something will break later down the line. I bricked my Ubuntu 
installation twice trying to get it to work.
So I'm running Ubuntu 19.10 now, for this to work any older version will not 
work (at least not with this method).
So currently 19.10 is running gnome-shell 3.34.1 and we'll need to downgrade to 
3.34.0 as this includes the fix, before it was reverted. Unfortunately the 
compiled packages have been removed so we'll have to download and install them 
manually and figure out the dependencies so things don't break.
Luckily however, Launchpad has some built packages, so we'll need to download 
for mutter:

gir1.2-mutter-5_3.34.0-3ubuntu1_amd64.deb
libmutter-5-0_3.34.0-3ubuntu1_amd64.deb
mutter-common_3.34.0-3ubuntu1_all.deb
mutter_3.34.0-3ubuntu1_amd64.deb

and for gnome-shell:

gnome-shell-common_3.34.0-1ubuntu1_all.deb
gnome-shell_3.34.0-1ubuntu1_amd64.deb

If the direct links doesn't work, here's where I found all the dpkg
files, or if you're not running amd64 architecture, you should also be
able to find alternatives:

mutter-3.34.0-3ubuntu1
gnome-shell-3.34.0-1ubuntu1

So, once you've got all the files you need. Open the terminal and the following 
command to exit the desktop enviroment (I don't know if this is needed but why 
not?):
sudo init 3
Then install each and everyone of your dpkg files with sudo dpkg -i 
/path/to/deb/file like so:
sudo dpkg -i gir1.2-mutter-5_3.34.0-3ubuntu1_amd64.deb
sudo dpkg -i libmutter-5-0_3.34.0-3ubuntu1_amd64.deb
sudo dpkg -i mutter-common_3.34.0-3ubuntu1_all.deb
sudo dpkg -i mutter_3.34.0-3ubuntu1_amd64.deb
sudo dpkg -i gnome-shell-common_3.34.0-1ubuntu1_all.deb
sudo dpkg -i gnome-shell_3.34.0-1ubuntu1_amd64.deb
Do not worry if it complains or warns about missing dependencies or breaking 
dependencies. This is because you have a newer version installed, and we're 
replacing them one by one.
Once finished, we start the desktop environment again with:
sudo init 5
Finally, we wanna let APT know not to update these packages, because that would 
undo everything. We do that by running following:
sudo apt-mark hold gir1.2-mutter-5
sudo apt-mark hold libmutter-5-0
sudo apt-mark hold mutter-common
sudo apt-mark hold mutter
sudo apt-mark hold gnome-shell-common
sudo apt-mark hold gnome-shell
Now you're done!
Once everything has been fixed and maybe you do want to upgrade all your 
versions, just run the previous commands but substitute hold with unhold. That 
should tell APT that it's okay to upgrade those packages again.

2019-11-04 Thread Tobias Bonnesen
I know nothing about Linux/Ubuntu and how it works, but I'm also having
this issue, with a R-Go split keyboard. I find it very cool that one can
use 'xev -event keyboard` to get an idea of what's happening behind the
curtain. And it made me research. According to this link:
https://tronche.com/gui/x/xlib/events/window-state-change/mapping.html
--- the MappingKeyboard appears, when the keyboard mapping was changed..
Which, without knowing anything about how this works, leads me to
believe that something, somewhere, either believes the keyboards to be
of two different mappings, or something is forcing them to be of two
different mappings.

Maybe, if one manually sets the mapping of both keyboards, to be exactly
the same? I tried 'xinput -list | grep key' together with 'setxkbmap
-device [number] -layout [layout]' to try and force the dansh layout on
both keyboarsd, but without avail. Any ideas?

This issue was fixed in Ubuntu 19.10. I switched from 18.04 to Eoan on
2th September and the bug was gone. Unfortunately one month later,
somewhere around the beginning of October I upgraded my 19.10 system and
the bug was present again. Awesome! :D

Since I am a newboy to Linux I dont know ho to roll back this upgrade
and as far as I got it, its  not that easy to downgrade gnome while wont
touching the other packages. When somebody knows how to do this, pls go

I have the same issue, but when using 1 keyboard and the xdotool. I use
xdotool to input keypress like XF86AudioPlay, and others multimedia
keys. This only happen when using the gnome. In wayland there is no such
issue. The real keyboard does not have the multimedia keys. The system
became shortly unresponsive everytime I switch from the real keyboard to

[Bug 1777708] Re: Desktop briefly becomes unresponsive when typing on 2 keyboards at the same time

2019-06-28 Thread Max Schillinger
Maybe this helps to find the cause for this bug:

When I run `xev -event keyboard` and press some keys, I see a KeyPress
and a KeyRelease event for every key. When I press a key on another
keyboard, I see a MappingNotify event first and then a KeyPress and a
KeyRelease event:


KeyPress event, serial 28, synthetic NO, window 0x681,
root 0x1a9, subw 0x0, time 1560057, (183,63), root:(1054,989),
state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
XLookupString gives 1 bytes: (20) " "
XmbLookupString gives 1 bytes: (20) " "
XFilterEvent returns: False

KeyRelease event, serial 28, synthetic NO, window 0x681,
root 0x1a9, subw 0x0, time 1560169, (183,63), root:(1054,989),
state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
XLookupString gives 1 bytes: (20) " "
XFilterEvent returns: False

# now typing on another keyboard

MappingNotify event, serial 28, synthetic NO, window 0x0,

KeyPress event, serial 28, synthetic NO, window 0x681,

state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
XLookupString gives 1 bytes: (20) " "
XmbLookupString gives 1 bytes: (20) " "
XFilterEvent returns: False

KeyRelease event, serial 29, synthetic NO, window 0x681,
root 0x1a9, subw 0x0, time 1562329, (183,63), root:(1054,989),
state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
XLookupString gives 1 bytes: (20) " "
XFilterEvent returns: False


Maybe this MappingNotify event triggers something in Gnome that needs a second 
of processor time.

I bought a Logitech K840 mechanical keyboard couple days back I noticed
the lag in 18.04 and 18.10 if I press a lot of keys at the same time.
And I've verified that it only happens in GNOME. I haven't tried it in
Wayland though. I didn't notice this issue with my previous bluetooth

2018-09-13 Thread Bobby Steed
I too have issues with keyboard input lag on Ubuntu 18.04. I've made
sure I'm current on all updates, I'm using the US layout and my language
is set to English.

In my case I am using a KeyMouse Track (which the OS recognizes as two
separate keyboards) but I have confirmed that it isn't related to the
keyboard devices - two Logitech G810 keyboards plugged in simultaneously
exhibit the same behavior.

As others have described, there is significant lag when pressing keys
from two keyboards in an alternating fashion, and the faster you press
the keys, the longer the delay before anything shows up on-screen once
you stop typing. If only keys from one device are pressed, there is no
discernible lag even if both keyboards are still plugged in.

Hopefully we can get some traction on this. I don't think Wayland is a
viable option for me as I have an nVidia graphics card and I also have
to use Skype for work... and I don't really want to switch to Plasma
either.

Great to see some confirmations!

For anyone skimming the comments, I'd like to emphasise that this is
_not_ an R-Go specific issue. It can be reproduced by typing on any 2
connected keyboards at the same time. So it's a more general problem,
which just happens to manifest itself for users of the R-Go keyboard(s).

Yes, the fix i did solved the lag everytime i switched keyboards. The
problem is a small lag still happen if i hit the two keyboards at the
same time. As i only type on one keyboard at a time, it doesn't bother
me, but it will prabably bother you.

Right. It may inherit it from some of the other, more general layout
files, though. But still:_ Switching to English layout didn't work for

Did you set the language to English as well? I've tried in Ubuntu and it
worked as well.

BUT I just found out that my solution may not solve your problem.
Although it removes the lag between keypresses, if you type two keys at
the same type (which happens when you type too fast), there is a small
lag. In my case, i don't see any problem, because the secondary keyboard
is for a very specific use.

Also, i looked at /usr/share/X11/xkb/symbols/dk file, and looks like the
Scroll Lock isn't mapped there.

Interesting findings, Pedro. How did you come up with that? What led you
in this direction? Did you have a change to try this in Ubuntu yet?

However, this fix doesn't work for me. Switching from Danish layout to
English does not get rid of the lag (I tried both US and UK English
layouts; don't know if there's a difference).

2018-08-29 Thread Pedro Palhares
After being annoyed by this bug for a long time, i started digging and
found a workaround. Today i found that the bug is only present when i'm
using certain keyboard layouts ("Portugues (Brasil)") and was not
present when i changed the layout to EUA and language to English (need
to set them both to English).

After some digging i found out the culprit is the ScrollLock key and that can 
be fixed by editing the  layout file, which in my case is found at 
/usr/share/X11/xkb/symbols/br. The only modification i did was to remove or 
comment the line: modifier_map Mod3   { Scroll_Lock };
After that, set the language and layout back to Portugues (Brasil) and the 
problem was gone!

No more delays between typings.

PS: I tried this on Fedora, i will try this on ubuntu tomorrow.

This bug can be easily triggered by typing with two keyboards, Everytime
you switch from one keyboard to the other, there is a lag. If you type
fast enough you can even freeze the application. Other way to trigger
this bug is to use xbindkeys with xautomation, everytime i try to
simulate keyboard typing, the lag is there.

It happens with XOrg and Gnome, doesnt happen in wayland. The problem is
i cant use wayland with NVidia driver.

> It is important that bug reports be filed about source packages so

Sure! But I have no qualified guess.

I did some additional testing today, which may be helpful to others, but
confused me a bit more:

I installed Plasma, and here the problem doesn't seem to be there. It
feels like there's a slight delay when typing a lot of things at the
same time, but it might just be Plasma's way of working. I haven't used
it before, so I can't really say whether the slight delay is just how
things work or is related to this issue.

But I also found out that I'm able to start a Wayland based Gnome
session. Doing that, there's absolutely no problem with they keyboard.
All multi-keyboard typing is shown instantly and no UI freeezing.

Based on this, I'm a bit confused about what package to file this bug
against, as Plasma (as far as I know) runs on top of X, and Gnome works
fine without X.
