Just one little thing to watch, observed on a official 2.8.0 iso buster install:

if you start the script in a root shell using "su" (like me), then make sure you get root by doing "su -". Just "su" (without the "-") will leave the path not properly set.

I cannot get this to run on a Raspberry Pi4. This is the error msg:
pi@linuxcnc:~/Downloads $ sudo bash lcnc-hw
ls: cannot access '/proc/sys/dev/parport': No such file or directory
dpkg-query: no packages found matching xdotool*
dpkg-query: no packages found matching lshw*
dpkg-query: no packages found matching bc*
Cannot proceed, need missing packages to be installed:
for example: apt-get install  dialog xdotool lshw firefox lm-sensors bc
Want me to install it for you now? [Y/n]y
Standby, I am going to install the required packages.

I lack a pi4 - yet. I might get one soon. The errors you got. Afaik the stock pi4 is based on debian buster, which is exactly what I am using as my test pc (dell 980) for "lcnc-hw" script. I will look into that on a fresh install however.

The problem is, I had deliberately removed all required packages including firefox to test whether the script would recognize and successfully install those. On my machine it worked, not on yours. So I am not satisfied or happy.

Has to work.

But Thanks for the reply anyway.

Hi all

Attached is an updated version. what's different?
  • (hopefully better info on desktop environment, window manager and display manager
    If what you have, is not what is evaluated, kindl post pstree here and give some hints on what you use. I might be able to fix it later.
  • if "snd" modules are detected, a script to "fake" install and thus avoid them from being loaded is added
  • some bugs eleiminated and also typos. If you find others, kindly nitfy me.
