hi ! guys !

first post so please be kind :wink: (I did do a search and couldn’t find the solution so…

Just installed the latest image of volumio on raspberry pi 3 and the official 7" touch screen display. It all seems to be working but…

Is there a way I can disable the pinch zoom on the local chromum thats used on the local 7" touch screen display?

Thanks!

so…i almost figured it out myself (lol) after some digging around i found that…

the process that volumio seems to start is “chromium-browser” and there does seem to be a switch to disable touch pinch as per:

–no-touch-pinch

Question is - where abouts does the volumio plugin for the official 7" display start the “chromium-browser” process?

Anyone ?

Since it’s an official Volumio plugin you can find it on the Volumio github pages. According to the code there it should be “/opt/volumiokiosk.sh”.

The official github: github.com/volumio :wink:

ok great thanks - I managed to switch it off as you suggested, I changed the file “/opt/volumiokiosk.sh” and this line:

/usr/bin/chromium-browser --disable-session-crashed-bubble --disable-infobars --kiosk --no-first-run 'http://localhost:3000'

to:

/usr/bin/chromium-browser --no-touch-pinch --disable-session-crashed-bubble --disable-infobars --kiosk --no-first-run 'http://localhost:3000'

Question is - Should this be changed in the github ? I much prefer it as always having the volumio fullscreen is mich better (sometimes i’ve noticed the GUI seems to zoom in and then I have to pinch to zoom back out again).

I forked the code and created a pull request (never done this before so be kind :slight_smile: ) here:
github.com/volumio/volumio-plugins/pull/53

Thoughts ?

Thank you for this post. Since you’ve discovered some interesting parameters, id like to ask if it is possible to start chromium with a zoom factor of 85. (Or somewhere in netween 80-90)
I find this a better size for the 7’ screen, not to mention that it gets rid of the right side scrollbar which is no longer needed.
I know that zooming out can be achieved using Ctrl -, but it would be more convenient if this was implemented from startup.
