LightDM kicks me out when I run rsync

Postby noober1983 » 2018-05-13 22:34

Hello all.

I just installed Testing+XFCE on a Dell Inspiron 5667. I installed version 4.13 of xfwm following the instructions here to solve video tearing.

While on my user XFCE session, whenever I start rsync to recover my data from a backup USB hard drive the screen goes black and I get the lightdm greeter; it's exactly the issue discussed here, save the fact that I am not on a VM. The last time I got this error/bug rsync had been running for about 1 minute; sometimes it gets longer, more than 10 minutes, before I get kicked out of the XFCE session.

Here's what lightdm.log says:
Code: Select all
[+4300.08s] DEBUG: Greeter requests session lightdm-xsession
[+4300.08s] DEBUG: Seat seat0: Stopping greeter; display server will be re-used for user session

[+4300.17s] DEBUG: Session pid=4585: Logging to .xsession-errors

I looked at .xsession-errors but nothing relevant appeared. This is seat0-greeter.log:

I don't know what the last process is supposed to be. I'd had trouble on this box before using Linux Mint regarding the display; they were solved installing the relevant firmware to the i915 Intel card, now available here.

I have been trying to rsync my USB HDD with my local HDD all day now; I finally got to the point where I copied and pasted in Thunar (there were just a few directories left), and that went on almost smoothly (the system went slow sometimes, but the files were copied and the session wasn't terminated).

EDIT: I forgot to mention that I also just installed Testing+XFCE with Openbox instead of xfwm4 on another laptop (Dell Inspiron 1090, a very small box) and there rsync works fine and runs for hours (quite literally) uninterrupted.

EDIT 2: Also happened when running Rhythmbox and it was reading the music database.

I need to know how to diagnose and solve this, I use rsync to backup everything in my laptop to the USB HDD.

Thanks in advance! Cheers!
