No TouchUI image on Waveshare 3.5" with 2017-11-29-octopi-stretch-lite-0.15.img

[kimnach]

First off, I am just starting out in the 3D-printing arena (Folgertech FT-5--still unused). Because I have a spare RPi with a Waveshare SpotBear (3.5" touch, https://www.waveshare.com/3.5inch-rpi-lcd-a.htm), which had been used with HomeGenie for home automation, I decided that before firing up the FT5 I would use the RPi with TouchUI.

The installation and set-up went fine with the Octopi Jessie-lite (version 0.14). The TouchUI interface displayed on the 3.5" screen. But being one to not leave well-enough alone, I saw that there are nightly builds available with Stretch. So, I downloaded 2017-11-29-octopi-stretch-lite-0.15 and proceeded to install it on a 32GB Samsung EVO. All went well until TouchUI. There is something which I did subtley differently or there is an issue with.....well, probably user error.

I followed the instructions, as I had with the Jessie version, as given at https://github.com/BillyBlaze/OctoPrint-TouchUI/wiki/Setup:-Boot-to-Browser-(OctoPi-or-Jessie-Light). All that happens is the arrow first displays in the center, an under-score cursor then briefly in the upper right, the arrow flashes again in the center of the 3.5" screen, then the screen goes blank. Undaunted, I checked out this thread and went completely through it: https://github.com/BillyBlaze/OctoPrint-TouchUI/issues/98.

Issuing a chromium-browser command results only in "[1547:1547:0106/010757.905273:ERROR:browser_main_loop.cc(582)] Failed to put Xlib into threaded mode.
(chromium-browser:1547): Gtk-WARNING **: cannot open display:"

lightdm is up to date (also ran update, upgrade, and dist-upgrade all in hopes of solving issue).

here is my Xorg log: Xorg.0.log

Fortunately I have the image of the working Jessie version to which I can always revert. In the mean time, I will image this and then try to a full raspbian-Stretch with octoprint and TouchUI.

Hi @kimnach,

Thanks for reporting, first off I cannot see any obvious issue(s) at all. Are you sure that the driver you installed (LCD-show) is available for Stretch?? Or was it a version for Jessie?

The issue #174 that was reported, was someone who successfully set up TouchUI on Stretch. So if you have the right driver, it should be do-able.

Althrough I am still unsure that Chromium is stable on Stretch. See #174 for some details.

Paul, I just installed the full version of Stretch, booted, and installed the video driver for the 3.5" monitor (again, it plugs into the GPIO). The monitor and touch work, so it wasn't a driver issue. I will see if I have time tonight to install Octoprint.

BTW, one of the oddities that occured yesterday (after my post) was that the touchui displayed on my windoze box's browser when Octoprint server started. I forget which of the settings turned it off.

Thanks, greg http://kimnach.org

Paul, I know that this is a different issue than what I originally had posted, and probably would be best addressed in a new ticket or having this one re-titled. I cannot get Octoprint server to start. I tried late into the wee hours of the morning to install Octoprint (per https://github.com/foosel/OctoPrint/wiki/Setup-on-a-Raspberry-Pi-running-Raspbian) --first with a virgin installation of a full Raspbian Stretch and then with subsequent updates and then dist-upgrade. Each time I copied the commands line-by-line into PuTTy.

During the initial installation of Octoprint, starting the server (PuTTy side) froze at "writing cache" or some such echo; however, the Raspian desktop remains responsive on the 3.5" LCD--so the pi is not freezing up. Rebooting and attempting to start the server freezes at different points. I have tried numerous times to start the server and, of course, it is not accessible from a browser. I will note that during the installtion process (for example at "./venv/bin/python setup.py install") there were WARNINGS having to do with various missing .gif, .au, .txt, folders already either exist or do not exist, etc. However, there never were any ERRORS echoed back. Example: Running future-0.15.2/setup.py -q bdist_egg --dist-dir /tmp/easy_install- gyqWBn/future-0.15.2/egg-dist-tmp-AV6Lx6 warning: no files found matching '.au' under directory 'tests' warning: no files found matching '.gif' under directory 'tests' warning: no files found matching '*.txt' under directory 'tests' zip_safe flag not set; analyzing archive contents...

Sunday, 7 January 2017 Install Attempt Today I decided to attempt install as root to see whether or not that helps. Well, still no joy. Raspbian Stretch boots into the desktop and displays on the 3.5" LCD. But Octoprint seems not to be properly installed.

Not knowing which log files would help, here is a step-by-step output of commands when logged in as root. (After the inability to connect to Octoprint with a browser and desperate for some success, I "over-wrote" the installation by re-entering all of the commands while logged in as "pi" and prefixing all commands with "sudo." See end of post: "OVER RE-INSTALL.")

Command lines are shown, and the echos (as appropriate) follow.

Hi Greg,

Thanks for the detailed information! And I'm glad you where able to make it work.

I will use your information once I'll get to supporting Stretch. For now I am closing this issue.

Thanks again and regards, Paul
