Problem
Looking at your /var/log/syslog you see entries every few seconds like the following:
|
1 2 3 4 |
Mar 1 15:44:52 L530 systemd-udevd[11464]: failed to execute '/lib/udev/socket:@/org/freedesktop/hal/udev_event' 'socket:@/org/freedesktop/hal/udev_event': No such file or directory Mar 1 15:44:52 L530 systemd-udevd[11451]: Process 'socket:@/org/freedesktop/hal/udev_event' failed with exit code 2. Mar 1 15:44:54 L530 systemd-udevd[11479]: failed to execute '/lib/udev/socket:@/org/freedesktop/hal/udev_event' 'socket:@/org/freedesktop/hal/udev_event': No such file or directory Mar 1 15:44:54 L530 systemd-udevd[11466]: Process 'socket:@/org/freedesktop/hal/udev_event' failed with exit code 2. |
Solution

|

sudo apt-get purge hal |
