[Kernel-packages] [Bug 1813765] Re: Freeze on Lenovo laptop in dock station
Experienced the same problem as the OP. Downgrading to 4.15.0-43 worked for as well. The only difference is that my laptop is Dell E7450. To be more specific, With dock and an external screen the system freezes when I close the laptop lid. When booting with the laptop lid is closed, the system does not even get to login screen. With laptop lid open everything works. With laptop not in dock everything works. -- 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/1813765 Title: Freeze on Lenovo laptop in dock station Status in linux package in Ubuntu: Confirmed Bug description: I have a Lenovo T470s laptop with a Thinkpad Ultra dock.

[Kernel-packages] [Bug 1590985] Re: Wifi non-functional after suspend (Intel 6205)
I can confirm same behavior as James Ferguson on a Thinkpad W520 with Intel Wireless Centrino 6205 Advanced-N. Network manager fails to display any signal strength and visible networks, but I am actually connected and internet works. This didn't happen on Ubuntu 14.04. -- 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/1590985 Title: Wifi non-functional after suspend (Intel 6205) Status in linux package in Ubuntu: Incomplete Bug description: Often, but not always, on resume from suspend my wifi does not connect.
