I don't know if it was coincidence. $ uname -a Linux deus-ex-machina 4.18.0-25-generic #26~18.04.1-Ubuntu SMP Thu Jun 27 07:28:31 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 18.04 / Linux Mint 19.1 In the journalctl I recognize DRM errors. I put it in sleep 11:xx o'clock and woke it up 14:xx o'lock. Then I got these DRM errors and did need to hardreset it. (Documented as REBOOT in the log). I assume that my 3 bug reports (this, docking station, user session crash) are related to the nvidia driver in combination with the ubuntu kernel? Or just coincidence. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 DistroRelease: Linux Mint 19.1 HibernationDevice: RESUME=UUID=4a747812-cab0-438b-ace1-a46b73f00d4a InstallationDate: Installed on 2018-07-21 (367 days ago) InstallationMedia: Linux Mint 19 "Tara" - Release amd64 20180626 Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 005: ID 058f:9540 Alcor Micro Corp.
