BBB Standalone mode: desktop doesn't appear

by rstephe on Wed Jul 20, 2016 7:43 pm

Just bought your BeagleBone Black - Element 14 (Debian) version. It works fine in PC-attached mode, but I need to run it standalone with an HDMI monitor. I followed the instructions on the Quick Start Guide insert, connecting ps, kbd and mouse as well as the HDMI monitor. After booting up, the penguin appeared briefly, then a white screen with the mouse cursor, and that was it. No desktop appeared. The LEDs User 0 (heartbeat), User 2 (kernel activity) and User3 (eMMC access) flash as expected. So what's wrong here?

For starters, is this a hardware problem, is there a step missing for the Debian version in the instruction, and/or a software mis-configuration? Is it worth updating the image version (currently BeagleBoard.org Debian Image 2015-11-12), or is the problem elsewhere? If there is a hardware pb, does updating the image version void the warranty?

Hello, could someone please reply to these QQ?

P.S. a cursory look through the syslog and Xorg.0.log doesn't show any smoking guns to me, FWIW.

Sorry to hear about the trouble. It is OK to update the image on the internal storage (eMMC) or boot from an image on a microSD card. The warranty will not be affected.

I would suggest trying the latest Debian image on:
http://beagleboard.org/latest-images

I would recommend trying Debian 8 (Jessie) first:
Debian 8.4 2016-05-13 4GB SD LXQT image

If that doesn't work, then try the Debian 7 (Wheezy):
Debian 7.11 2015-06-15 4GB SD LXDE

Thanks, Drew, on the third attempt, Debian 8.4 is working. Amazing how, with all the documentation, there are still a lot of things that remain unsaid, or at least unclear. It's like a recipt where they say "add two eggs" but never tell you to remove the shells first!
