I collected the information. The bug does not appear on a certain behaviour, but from time to time. Since this is my working computer (and I expect a LTS release to be usable for a working computer ;) ), unfortunately I can not keep eclipse / Java applications closed for some time.
I am not using network filesystem mounts, but an ecryptfs-home directory and an luks / btrfs data mount, resulting in the following mount-output: /home/.ecryptfs/reichelt/.Private on /home/reichelt type ecryptfs (rw,nosuid,nodev,relatime,ecryptfs_fnek_sig=acac39a53194aaed,ecryptfs_sig=bc053eeba3eaac08,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs) gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,relatime,user_id=1000,group_id=1000) /dev/mapper/komp on /home/reichelt/daten type btrfs (rw,relatime,compress=lzo,space_cache,subvolid=5,subvol=/) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769695 Title: Freeze of Surface for 2 Minutes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1769695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
