Quick question about 16.6.0
In the release note of 16.6.0 is says "Disabling all native-Android animations on Android emulator"
Does that mean I don't have to set these globals anymore?
adb shell "settings put global window_animation_scale 0.0"
adb shell "settings put global transition_animation_scale 0.0"
adb shell "settings put global animator_duration_scale 0.0"
Thanks
Indeed, this is exactly what it means. More so, Detox will ensure this will be applied even in an environment running tests on multiple emulators, concurrently.
This feature had a bug before and they just fixed it in this release: 18.18.0

I have properly installed and setup WSL2. It works fine.
I also setup X11 forwarding and X server (VcXsrv). I can launch GUI apps such like konsole or gvim or even google-chrome from a bash shell.
Now I want to launch konsole by simply double clicking a short cut on the desktop without launching the bash command mode terminal. How should I do it?
I tried running this in cmd:
> wsl /usr/bin/konsole
and it reports:
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
I'm guessing it is because some X11 forwarding configurations were not properly setup, so I created a k.sh as follows:
#!/usr/bin/bash
export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
export LIBGL_ALWAYS_INDIRECT=1
/usr/bin/konsole &
The first two lines were the X11 settings in my .bashrc, the last line launches konsole.
It works fine under bash environment; but when I ran
wsl k.sh
from windows cmd environment, it silently quitted without launching the konsole.
I'm out of ideas. What should I do to directly launch konsole or other Linux GUI apps under windows without having to getting into bash?
Thanks in advance.
You are asking about two different command-lines, and while the failures in running them via the wsl command have the same root-cause, the underlying failures are likely slightly different.
In both cases, the wsl <command> invocation results in a non-login, non-interactive shell where the command simply "runs and exits".
Since the shell is non-login/non-interactive, your startup files (such as ~/.bashrc and ~/.bash_profile, among others) are not being processed.
When you run:
wsl /usr/bin/konsole
... the DISPLAY variable is not set, since, as you said, you normally set it in your ~/.bashrc.
Try using:
wsl -e bash -lic "/usr/bin/konsole"
That will force bash to run as a login (-l), interactive (-i) shell. The DISPLAY should be set correctly, and it should run konsole.
Note that the quotes probably aren't necessary in this case, but are useful for delineating the commands you are passing to bash. More complicated command-lines can be passed in via the quotes.
As for:
wsl k.sh
That's likely a similar problem. You are doing the right thing by setting DISPLAY in your script, but I notice that you aren't using a fully-qualified path it. This would normally work, of course, if your script is in a directory on the $PATH.
But I'm guessing that you might add that directory to the $PATH in your startup config, which means (again) that it isn't being set in this non-login, non-interactive shell.
As before, try:
wsl -e bash -lic "k.sh"`
You could also use a fully-qualified path, of course.
And, I'm fairly sure you are going to run into an issue with trying to put konsole in the background via the script. When WSL exits, and the bash shell process ends, the child konsole process will terminate as well.
You could get around this with a nohup in the script, but then you also need to redirect the stderr. It's probably easiest just to move the & from the script itself to the command-line. Change your k.sh to:
#!/usr/bin/bash
export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
export LIBGL_ALWAYS_INDIRECT=1
/usr/bin/konsole
Then run it with:
wsl -e bash -lic "k.sh &"`
Finally, a side note that when and if you can upgrade to Windows 11, it will automatically create Windows Start Menu entries for any Linux GUI app you install that creates a .desktop file. You can manually create .desktop files to have WSL create Start menu items for most applications.
For reference, in Windows 11 it's easier. To run a GUI application without a terminal window popping up, you just need to call wslg.exe instead of wsl.exe.
So, for example:
target: C:\Windows\System32\wslg.exe konsole
start in: C:\WINDOWS\system32
shortcut key: None
comment: Konsole
This tutorial shows how to install VcXsrv and and edit .bashrc to ensure that the "DISPLAY env var is updated on every restart".
DISPLAY env var needs to be dynamic setting.
I've used it successfully with WSL2 on Windows10 Version 21H2 (OS build 19044.2130) to run Chrome, Edge, and thunar. I'm using the Ubuntu 20.04 Linux distro.
To edit .bashrc follow these instructions.
I've tried the command adb shell settings put secure enabled_accessibility_services com.android.talkback/com.google.android.marvin.talkback.TalkBackService to enable talkback from adb shell. It's toggling the ui button which signifies the status of talkback, but talkback is not actually getting enabled.
I am trying to enable talkback programmatically for android 6.0. Is there any other way thorough which I can enable it?
Commands to toggle TalkBack:
// disable
adb shell settings put secure enabled_accessibility_services com.android.talkback/com.google.android.marvin.talkback.TalkBackService
// enable
adb shell settings put secure enabled_accessibility_services com.google.android.marvin.talkback/com.google.android.marvin.talkback.TalkBackService
Kudos to #zeh
Are you running this alongside any other accessibility services or UI Automation (which utilizes the accessibility APIs)? Accessibility services are only allowed to run one at a time, and attempting otherwise will cause exceptions all over the place. Check LogCat and see if TalkBack is attempting to start up, but throwing exceptions when doing so.
For convenience, I use a shell script to toggle this setting.
output=$(adb shell settings get secure enabled_accessibility_services)
if [[ "$output" == "com.android.talkback/com.google.android.marvin.talkback.TalkBackService" ]]; then
adb shell settings put secure enabled_accessibility_services com.google.android.marvin.talkback/com.google.android.marvin.talkback.TalkBackService
else
adb shell settings put secure enabled_accessibility_services com.android.talkback/com.google.android.marvin.talkback.TalkBackService

Webstorm can be launched from the command line using the command wstorm. However, would it be possible to launch more than one instance? Usually, the second time I run wstorm, it doesn't open another Webstorm for me and does nothing.
In OS X, this is apparently caused by an outdated wstorm (a Python script at /usr/local/bin/wstorm). I verified the solution indicated in this ticket with WebStorm 2016.1.3:
Go to Tools > Create Command-line Launcher....
UPDATE Nov-2016: As of WebStorm 2016.3, the default name of the launcher changed from wstorm to webstorm. If you prefer wstorm instead, make sure to edit the script name before clicking OK:
Just run:
WebStorm.exe "Full\path\to\the\project\that\contains\the\.idea\folder\of\your\project"
The project will run in the same instance but in a separted window as described here: https://www.jetbrains.com/webstorm/help/opening-multiple-projects.html
NOTE: This was tested on WebStorm 9.0.3 and may not work on previous versions.
I'm trying to run rvm on Angstrom linux on BBB.
When i try to launch rvm, i obtain:
RVM can not be run with set -o posix, please turn it off and try again.
Someone know about this?
This is a check to prevent running RVM from pure Sh shells, for proper functioning RVM requires Arrays(along other features) which are only available in Bash and Zsh.
Answer shared by #mapapis was useful to understand the reason (thanks) but I think precise steps to change the default login shell complement this and are useful.
As stated here you may need to change the login shell for your user in order to use the shell of your preference by default, in my case is bash so I made some changes the way I launch my terminal.
chsh is advised but in my particular case I'm using ConEmu Windows Terminal with Cygwin in a Windows 10 environment; sh.exe is used by default thus this RVM warning...
chsh is not available in Cygwin, so I followed this reccomendation that states that:
it is just a matter of changing (...) whatever shortcut you
are using to start cygwin to call {prefered shell here} instead
I hope this is useful. Gretings!
I'm trying to build a Webkit Kiosk on a Raspberry Pi.
I found a good start at: https://github.com/pschultz/kiosk-browser
The things I want to do:
1) Start the kiosk without logging in (with inittab?)
Peter Schultz pointed out adding the following line:
1:2345:respawn:/usr/bin/startx -e /usr/bin/browser http://10.0.0.5/zfs/monitor tty1 /dev/tty1 2>&1
But he did not explain the steps to make this work (for noobs).
What I did is add his code to a personal git repository and cloned this repo to /usr/bin/kiosk and sudo apt-get install libwebkit-dev and sudo make.
The line to add to inittab will be:
1:2345:respawn:/usr/bin/startx -e /usr/bin/kiosk/browser http://my-kiosk-domain.com tty1 /dev/tty1 2>&1
If I do this, I generate a loop or some kind...
If you want to automatically load a browser full screen in kiosk mode every time you turn on the rpi you can add one of these two lines to the file /etc/xdg/lxsession/LXDE/autostart
#chromium --kiosk --incognito www.google.it
#midori -i 120 -e Fullscreen -a www.google.it -p
The first is for chromium and the latter is for midori, the rpi default lightweight browser.
Hint : Since we will use the rpi as a kiosk we want to prevent the screen from going black and disable the screensaver. Edit the autostart file:
sudo pico /etc/xdg/lxsession/LXDE/autostart
find the following line and comment it using a # (it should be located at the bottom)
##xscreensaver -no-splash
and append the following lines
#xset s off
#xset -dpms
#xset s noblank
Save, reboot.

The upvoted answer suggest to run LXDE for it. You could also do it without such a heaver desktop enviorment. You could just start midori or chromium in an X session:
xinit /usr/bin/midori -e Fullscreen -a http://www.examples.com/
xinit chromium --kiosk http://www.examples.com/
Sometimes Fullscreen mode of midori is not working as expected and midori is not using whole screen. In these cases you could map it inside a very simple window manager like MatchBox to get real fullscreen. Due to xinit you have to wrap everything in a shell script.
#!/bin/sh
matchbox-window-manager &
midori -e Fullscreen -a http://dev.mobilitylab.org/TransitScreen/screen/index/11
Autostart could be done simply be using /etc/rc.local.
More information concerning screensaver issues and an automated restart could be found here: https://github.com/MobilityLab/TransitScreen/wiki/Raspberry-Pi#running-without-a-desktop
Chromium has a dependency problem on some debian derivate for arm architecture. For Cubian you find the bug report here. I am not sure if you could install chromium on latest Raspbian without problem.
But I really could recommend midori. It's very fast and support for modern web technologies is very good. As Chromium it is using webkit as rendering engine. If you miss some html5 / css3 features consider an update of libwebkitgtk (for example by using package of debian testing).
It's possible you haven't set the DISPLAY environment variable.
Try:
export DISPLAY=:0
/usr/bin/startx /usr/bin/browser
Or, browser can also take a display argument (so you don't need the environment variable):
/usr/bin/startx /usr/bin/browser :0
This works for me on Raspbian from a standard terminal shell (I'm logged in over SSH).
Updated for the current version of Raspbian (with Pixel desktop) install with noop 2.0.
I found you need to edit in two different places to get it to work.
/etc/xdg/lxsession/LXDE/autostart
/home/pi/.config/lxsession/LXDE-pi/autostart
So my configure file is:
# #xscreensaver -no-splash
#xset s off
#xset -dpms
#xset s noblank
#chromium-browser --kiosk --incognito http://localhost
And that's it.
You should probably start with checking if /usr/bin/kiosk/browser is working at all. You should start normal X session (graphical environment) on your RaspberryPi, launch terminal, try running this command:
/usr/bin/kiosk/browser http://my-kiosk-domain.com
and see what it prints on the terminal. Is this working? Do you see any error messages?

I think Instant WebKiosk for Raspberry Pi could be useful for you.
