[Trisquel-users] Display manager freeze and 100% disk usage bugs

[hd-scania]

Since late July I've found that LightDM and SDDM are both frozen but unable  
to escape to tty.
The another issue is there is a bug mis-displaying 100% hard drive usage in  
"df -Th" command, but under "sudo du -shmx /*" the sum of every dirs are  
always less than 16384 (16GiB = 16384MiB, my Trisquel root filesystem is in  
this size), this also still causes my LightDM to be frozen as above.
