Description Cristian Aravena 2018-10-25 19:53:15 UTC
Hello,

Open bug in launchpad.net
https://bugs.launchpad.net/bugs/1799994

"Lenovo ThinkPad W540 docked with an ultradock. 3 external displays running on VGA, DVI and display port all connected to the dock. BIOS mode set to run external displays ONLY with nvidia chipset. prime-select nvidia run.

When running under 4.15.0-36-generic with nvidia 390.77-0ubuntu0.18.04.1 I boot and all three external displays run fine.

Upgrading to 4.15.0-38 and Xorg starts up, but none of the displays light up."

Best regards,

It appears to be a kernel issue, per the downstream bug report.
Comment 2 Tim Riker 2018-10-26 19:11:37 UTC
Looks like it happened the same time as a kernel upgrade, but it's not a kernel issue, it looks like an nvidia driver issue.
