Web browser in LCD (4D) using IoT image

GoogleGroups

Hi All

I hope someone can help ?

I am running a Debian IoT (non GUI) image on my BBB. I have a 4D LCD cape installed which is working and shows the Linux command line.
I would like to run a web browser in order to show the Node-Red dashboard of my running Node-Red instance.

I have successfully installed Chromium-browser (it didn’t show any errors), but if I try to run ‘chromium-browser’ from the command line it does nothing - I want the web browser to show in the LCD window.
Is this possible ??
Do I need to install any other applications (can this be done without installing something like LDXE)??

Thanks in advance for any help you can offer

P.s. I am using the IoT version of Debian as I wanted to try and keep the memory foorprint to below 4Gb

Cheers

Michael

You'll need Xorg installed

Follow "some" of this example i did for show:

https://eewiki.net/display/linuxonarm/FLIR+Lepton+on+BeagleBone+Black+and+Green#FLIRLeptononBeagleBoneBlackandGreen-Setupbasicwindowmanager

aka ignore the lepton, qt5, and spi stuff. But the minimal
openbox/slim/autostart can be easily used for your application.

ps ignore the 16 bit depth in xorg.conf, newer kernels' auto do this..

i should just create a new x11 example, or redo that project with
todays kernel. :wink:

Thanks Rob - I will give that a go

Hi Rob,

Many thanks for the help.
Adding the Xorg got the LCD screen up and running. I do have a couple of question that you may be able to answer??
Firstly, when the BBB initially loads it goes to the user logon screen which seems to be incorrectly scaled - do you know if there is a way to correct scaling?

Secondly, when I load a page into the chromium browser it seems really slow laggy & unresponsive - I am running Node Red and wanted the browser to view the output dashboard. Is this a problem with Chromium on the BBB - should I be using a different browser or are there some Xorg settings I can change to improve things?? If I monitor the dashboard through my PCs webbrowser via HTTP connection it is buttery smooth *with the BBB acting as the web server)

Many thanks for any help you can offer

Cheers

Michael

  Read the yellow box under "Using the Editor"
https://nodered.org/docs/hardware/raspberrypi

  Yes, that link is RPi oriented, but there can't be that much difference
for pure applications -- other than the inherent differences in RAM,
flash/SD, processor speeds, and number of cores (RPi-3 being a quad core
64-bit saddled by running 32-bit OS). {RPi-0: 512M LPDDR2, ? SD card, 1GHz
single core ARMv6 [deprecated ARM-11]; BBB: 512M DDR3, 4GB eMMC or ? SD
card, 1GHz single core ARMv7 [Cortex-A8]; RPi-3: 1G LPDDR2, ? SD card,
1.2GHz quad core ARMv8-A [Cortex-A53]}

  Might want to peruse the thread
