Touchscreen with eGalax Driver on two Monitors

English Hardware
1

Hello,
we are using 2 touch screens/monitors attached to one computer. At the moment only one of them can be used. I’m looking for a way to use both touchs at the same time.

configuration

  • two identical touchs (EETI, conductive)
  • communikation channel: 2x RS232
  • OS: openSuse 15.4
  • kernel: 5.14.21

I’m in email contact with the manufacturer EETI in Taiwan. Unfortunately, EETI is unable to help us.

After driver installation the file ’eGTouchL.ini’ can be found in the directory ‘/etc’. If I change something in this configuration file (recommended by EETI), it will be deleted automatically during reboot. By stopping and starting the application ‘eGTouchD’ a new standard ini file is genereated.
In addition, the ini file ’eGTouchL.ini’ is deleted immediately when I try to activate the system beep in the “eGTouch utility”. This causes an error.

Is there anybody who can help solving this problem.

Regards, Kov

In any case of a file suffering unwanted changes or deletion on a native Linux filesystem, one can employ the sledgehammer approach: setting the immutable attribute on the file to lock it down. Only chattr can add or remove the attribute. Without using chattr, an immutable file can only otherwise be affected by a reformat or removal of the filesystem itself.

sudo chattr +i eGTouchL.ini

Hi mrmazda,
many thanks for that tip. This sledgehammer solution works.
However, it does not explain or solve the basic problem.
Has anyone an idea?
