I’m on a new Librem 13v2 with latest PureOS.
This does NOT occur when logged in with GNOME on Xorg or GNOME Classic - only GNOME Default.
When inserting a USB volume of any kind (stick, mini, external drive) in any USB port -
- volume automounts
- IMMEDIATELY: user is logged out completely (to GNOME login screen)
- after login, volume is available as expected
This logout occurs whenever a USB volume is ejected as well.
