Upgraded the kernel through the standard channels: $ uname -a Linux talas 4.8.0-34-generic #36-Ubuntu SMP Wed Dec 21 17:24:18 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
The original problem seems fixed, it exhibits practically the same behaviour as with 4.9. Docking lights up the monitors, I still have to 'killall unity-settings-daemon' to load the configured monitor settings (order and rotation). I also had X crash to login on two occasions when suspend->dock->resume, but this is not reliably reproducible (works most of the time, will report when it happens again) and never when docking while awake. If this is considered as fix released, I shall file a bug with unity- settings-daemon about the config reload. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1651454 Title: [Lenovo Thinkpad T460p] Ultra Dock external displays not detected after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1651454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
