Johan and also iMac, thank you... I was trying to see whether this issue correlated with the type of cable between the dock and the external display; but obviously not since we're seeing it with both HDMI and DP.
I'm not suggesting that a particular item such as the Dropbox app, Logitech USB driver, etc is the cause; but I'm hoping that these observations may help those of you who are trying to reproduce the issue to do so. My background is application programming, not system; so I can offer anecdotal observations and check logs but am not able to dive into the code. I do urge those of you who can to do so. This is once again progressing. This morning (and after having allowed the kernel update to 5.8.0.36.40 just a couple days ago), the system *froze* rather than going to sleep. First I lost the external display. So I opened the laptop lid (docked) and had a bizarre set of 3 or 4 error messages. Those cleared to solid black before I could get a pic. I couldn't get any response after that so had to do a hard power down. Not good! I brought the machine up standalone, let it idle a few minutes, shut it down, and put it back into the dock. Then it was back to this bug's suspend after login. This again is Ubuntu 20.04.1, now the kernel just noted, on a T570 in the classic UltraDock using an external HDMI display, external Lenovo USB keyboard, and Logitech *bluetooth* mouse. Lid closed so external display is primary. Note that the Lenovo USB mouse has developed serious scroll wheel issues: I'm not yet sure whether that is Ubuntu or hardware. My overriding concern is that Ubuntu remains unstable at best since the mid September updates. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1841826 Title: Going to sleep instead of logging in while lid closed & external display Status in gnome-settings-daemon package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: I have the above described problem, which seems to be very similar to bug #1716160 - laptop is in docking station and 2 monitors are connected (HDMI, DVI) - If the lid is closed and I boot the laptop I can input my credentials in the login screen and after hitting ENTER the laptop goes to sleep - If I then press the power button of the docking station the laptop wakes up and goes straight to the ubuntu environment w/o any user identification The device is a Lenovo T420 with classic docking station. Ubuntu 18.04.3 LTS. Internal graphics Intel integrated grafics and dedicated Nvidia Quadro NVS 4200M with propriety driver 390.116. Behavior independent of the graphics used. I do not know what to do now since the latest state of bug #1716160 is "fix released" and so I guess it should be part of the ubuntu version I use? Thank you very much.
