Re: [beagleboard] Web browser in LCD (4D) using IoT image

2018-02-07 Thread Jeff Andich 
Hi someone on our team tried to run chromium on an external 
touchscreen/display connected to the BeagleBone Black, and noted similar 
slow response.

Is there a way to improve performance of chromium running on BBB or are 
there better alternatives?

Thanks!

Re: [beagleboard] Web browser in LCD (4D) using IoT image

2018-02-07 Thread Michael Dalby 
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

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. ;)

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.
