The best laid plans of touch screens and men.

I  had a few more things to do, I wanted to paint the hinge and brackets black, but I was so excited to get it working I jumped to the configuration of the software.

Now that Octoprint has plugins and one of them is the touchUI designed for LCD touch screens etc, I went through the steps of setting up the image on the Pi. I used Jessie Lite on to an 8GB SD card.
I went back to the computer and opened a browser and put in Local.Pi and connected from the browser. The OctoPrint GUI was now visible.

I then installed the Touch UI plugin.

The next step was to see the interface on the Raspberry Pi. This meant that the Lite in Jessie Lite was not going to cut it, I needed to run a browser, but Jessie Lite does not have X system that gives graphics.  I used the script to expand and load the X part of Jessie that was missing from Jessie Lite.

In all fairness, there was a warning that said something to the effect of loading more than Jessie Lite and it would probably not work well.

I got a Raspberry Pi, now I need a suitable distro for a touch screen

I installed Raspbian before Christmas & I thought I should update the distro seeing that there was a newer version dated Feb 2013.

The touch screen finally came and I plugged it in and the display worked but the touch screen did not.
I was about to send an email to their tech support, when I thought I could try another distro.

I found a utility called Berry Boot that allows you to multi-boot several different Linux distros and makes it much easier to install several distros on the same SD card and try them.

So I started adding distros to a SD card: Raspbian, Puppy, RaspRazor and Sugar. There was also an update for Berry Boot, & a newer version of Raspbian. Wow now the touch screen works!
Now that I had a working touch screen, my criteria sort of changed and there was always something that prevented a given distro from being chosen.
The criteria I had were
1) icons on the desktop
2) one click to start a program
3) ablity to access my network smb drive
4) no login screen.
5) the ability to increase the toolbar or desktop fonticon size to “finger size”

My thoughts for my kitchen computer is sort of a kiosk computer where there is no physical mouse or keyboard.
I’m also looking at Arch, Raspbian, Puppy, RaspRazor, Pidora, PiBang, Bodhi, with various desktops like E17 XFCE and Openbox
Right now I have PiBang – XFCE riding over top of Openbox. It seems like the front runner
