Chrome Kiosk mode ignores zoom settings

Question

I have a simple shell script that starts chromium in kiosk mode on a certain url. It works fine, but in kiosk mode the zoom level from Chrome's settings seems to be ignored.

I could normally use ctrl + or ctrl - to zoom in or out, but this is obviously not an option if the browser is run from the script without "human help"

Because of a low screen resolution, It is zoomed in too much by default. I tried the Chrome Autozoom extension, but for some reason this made it zoom out way too much (and it didn't matter at which zoom level I set the extension).

All I want is to be able to specify the zoom level when I start the browser in Kiosk mode. Any ideas?

We have this same setup [ linux kiosk running chrome in kiosk mode ] but I haven't seen this. You can set the default zoom settings in Chrome:

Are you syncing home directories and possibly overwriting chrome's settings directory? There must be some mechanism in your setup overwriting settings --- or possibly it's a permissions issue. Be sure to setup Chrome the way you want --- make sure the settings stick --- before enabling your privacy/security settings and scripts.

If chrome can't write to it's config directory, or, if that directory is getting overwritten your settings will not be preserved --- otherwise, a kiosk like you describe should work with the settings you specify. As I said, we have kiosks setup this way with default zoom settings for touchscreens with low resolutions.

Have any other info on your setup that might affect this issue?
