Public bug reported: Sometimes I boot the ThinkPad T460p, put it into sleep, wake it up and only receive a blackscreen until I hardreset the laptop with the power button, last time all happen without AC power I recognize now. 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1837547 Title: Ubuntu 18.04 Kernel 4.18 - Standby wakeup blackscreen - Hardreset needed Status in linux package in Ubuntu: New Bug description: Sometimes I boot the ThinkPad T460p, put it into sleep, wake it up and only receive a blackscreen until I hardreset the laptop with the power button, last time all happen without AC power I recognize now.
