Changing the hostname --> touchscreen doesn't work

Hello,

I’ve on problem:
I’ve to write a script, which changes the hostname (amongst others) of a system automatically.
So the script replaces the value in /etc/net.cfg. After that the system is rebooted.
The effect is, that the touchscreen of the system doesn’t work anymore.
So I changed the script: Before rebooting, the file /etc/system/trap/calib. (which
contains the calibration-settings of the touchscreen) is copied to /etc/system/trap/calib..
Sadly, this has no effect.
When I call “calib” (the tool which creates the …/calib.*-file with user-interaction) the
touchscreen works, but only until I reboot the system.

When I change the hostname with phlip everything works. But it must be done automatically.

Are there any further files, which has to be changed?
Or:
Is there another way to change the hostname? (Perhapps with ifconfig or something similar???)

Thanx a lot in advance.

Is the input. file (located in /etc/system/trap) used when using the touchscreen (I suspect that it is)?

Thanx for your answer.
I guess not. There is no input.-file in my /etc/system/trap (in both cases: when it does and doesn’t work.)

I’m still having the above problem.
Anybody out there with an idea? :slight_smile:

run “calib” and calibrate the touch screen and it will create a new calib.hostname file for your touchscreen driver

try “sync” before reboot, use “hostname” utility instead of rewrite net.cfg.
