When Chrome has crashed, it displays a warning (under the address bar) upon restart, offering to restore tabs. I'm launching chrome in kiosk mode and I don't want theses warnings to be displayed.

Is there a way to do this ?

You should run Chrome in Incognito Mode with this command:

chrome --incognito --kiosk http://127.0.0.1

Here they talk about running this command before starting Chrome to stop the Restore Bar from appearing:

sed -i 's/"exited_cleanly": false/"exited_cleanly": true/' 

    ~/.config/google-chrome/Default/Preferences

Based on @MiQUEL's answer to this duplicate question:

There are a few approaches.

Incognito mode (--incognito) helps, but it has several disadvantages, such as disabling the cache.

Passing --disable-infobars --disable-session-crashed-bubble works in some versions of Chrome, but, as of Chrome 58, it no longer works. (Removing the --disable-session-crashed-bubble was done as part of this issue; comments there suggest that the flag was intended to test the bubble feature and was not intended as an end-user feature to hide the Chrome warning).

The most reliable approach I've found is to manually edit Chrome's on-disk preferences. Here's how you do this on Linux. (Note that these instructions are for chromium-browser; Google Chrome itself uses ~/.config/google-chrome instead of ~/.config/chromium.)

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences

Putting it all together with a couple of additional flags that have been helpful for kiosk mode in one Chrome version or another:

#!/bin/sh

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'

sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences

chromium-browser --kiosk --no-default-browser-check --no-first-run --disable-infobars --disable-session-crashed-bubble "http://some_url/"

--disable-infobars --disable-session-crashed-bubble

while true; do

   chromium-browser --kiosk http://fotolia.com/ --no-first-run --touch-events=enabled --fast --fast-start --disable-popup-blocking --disable-infobars --disable-session-crashed-bubble --disable-tab-switcher --disable-translate --enable-low-res-tiling

   sleep 10s;

done

I believe --restore-last-session will also do the job.

This finally worked for me, and it's pretty simple:

1. Shut down Chromium gracefully


2. Change the "Change content" permissions of ~/.config/chromium/Default/Preferences to "Nobody"

That will lock the state of two variables, regardless of how Chromium
was shut down:

• "exit_type": "Normal"


• "exited_cleanly": true

Of course, only do that after you're done setting preferences

I have been trying to solve this problem for days. Incognito mode comes without cache, and changing Preferences file did not work for me.

Finally I have been able to solve by following steps below:

1. Go to chrome://flags url. Search for “Enable session restore bubble UI” and set it to Disabled.


2. open chrome with --kiosk --disable-infobars options.
