Package: lightdm
Version: 1.10.3-3
Severity: normal
Tags: patch
Dear Maintainer,
upstream bug #1190344 affects this version of lightdm. It was fixed in
upstream version 1.10.5.
It can be easily checked by the following steps:
- log in with lightdm
- check number of FIFO fds of lightdm
sudo lsof -p "pid of lighdm process" |grep FIFO | wc -l
- light-locker-command -l
- unlock session
- check number of FIFO fds of lightdm again
- number has increased by 8 in my case
This is problematic as lightdm reaches the maximum number of open file
descriptors at some point, which makes it impossible to unlock the
screen.
I have adapted the upstream patch to version 1.10.3-3 which is in unstable and
testing. It fixes the problem for me.
Cheers,
Philipp
