Problem in Kiosk mode in LUBUNTU
 

Dear Members and mentors,

I am bit new in Linux. We need to deploy HMI for an Industrial controller. The HMI is device is a tablet with Intel Atom Z3745 CPU.

I have installed Lubuntu 18.04 LTS. The HMI is based on HTML/JavaScript. I have called the Index.html page through .xsessionrc (mostly following this page: https://obrienlabs.net/setup-kiosk-ubuntu-chromium/, but I have user .xsessionrc instead of autostart desktop). Everything works well. The HMI has been tested for very long processes and everything works.

Now I have a problem that the Tablet does not mount USB device (flash drives) when the .xsessionrc is running (I can see sda1 if I do lsblk, but no mount point). If I disable .xsessionrc, USB devices are working fine (mounted automatically after insertion).

I have tried to force mount USB using UDEV rule. This also fails. It creates the folder, but USB is not mounted.

Can you please help me? I am totally stuck without any solution in sight.

we need more information about this:

• how exactly do the two startup methods differ?
• what is in the logs for the two usage scenarios?
• how exactly did you "try to force" it?

show us code in code tags, please.
