[Kernel-packages] [Bug 1813946] Re: linux-image-4.15.0-44-generic on Thinkpad T480s with docking station - unresponsive black screen
*** This bug is a duplicate of bug 1813663 *** https://bugs.launchpad.net/bugs/1813663 I had the same issue on Lenovo Thinkpad X1 Carbon (6th generation), also resolved by downgrading to the old kernel version. The monitors work with the docking station until the lock screen causes the computer to suspend. After that it's locked with black screens and unresponsive until I do a hard reboot using the power button. -- 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/1813946 Title: linux-image-4.15.0-44-generic on Thinkpad T480s with docking station - unresponsive black screen Status in linux package in Ubuntu: Confirmed Bug description: Upon upgrading linux-image-generic and linux-header-generic from version 4.15.0.43.45 to version 4.15.0.44.46, my Lenovo Thinkpad T480s no longer works when plugged into its docking station.
