Hello,

I am just trying to set up a pcduino3 nano with Debian Jessie.

I downloaded 4.9.7 and put it onto SD card, booted, logged into my sudo account, and then

apt-get install lightdm

followed by

apt-get update

apt-get upgrade

as per "Getting Started" guide.  I now have 4.9.12

 

LIghtdm fails to start with following message:

 

systemctl status lightdm.service -l
● lightdm.service - Light Display Manager
   Loaded: loaded (/lib/systemd/system/lightdm.service; enabled)
   Active: failed (Result: start-limit) since Tue 2017-03-07 21:41:18 CET; 17min ago

I tried

dpkg-reconfigure lightdm

but no change.

 

Any suggestions?

 

 

If you got the problem after the 1st reboot....

 

Look here:

 

try this

systemctl stop log2ram.service
install lightdm, run first time creating directory,
systemctl start log2ram.service

maybe it helps...

Thanks for your reply MacBreaker.

The problem persisted, but I found a log file that said Xserver not found.  I (re?)installed Xserver and now I get a login screen, but

I can't log in with either my account or root --- no error message on screen -- just redisplay of login screen.

 

Does anybody know what log file I should be looking for to find out what's not working?

Not sure if Xserver pulls everything you need. Try xorg.

I think it was Xserver-xorg that I installed.  I don't know if that's the same thing.

 

I forget what I did after that, but I got sign-in working.  But the Synaptic that I installed doesn't prompt me for pswd and just disappears.

 

Anyway, it's all in the past now -- I've learned about SSH, and the little acrylic box is now sitting in a dark place with just power and ethernet cables in it
