Basically is the same issue: I have a life book h760 with a docking station attached to it. The laptop is closed and two external monitors are attached to the docking station. After booting, the GDM appears on the correct monitors. After entering the password, one gets to gnome desktop and the desktop then goes into standby.
One has to press the turn on button on the docking station to wake up the laptop. All settings are default. All updates done. As far as I understood this is the exactly reported bug here. The gnome tweak tool is also set to default settings (done nothing there) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716160 Title: System goes to sleep with external monitor and lid closed after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1716160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
