I've tested with the latest Ubuntu and Xubuntu nightly live USB images. This is the first I had heard of those, and I'm very glad they are now available, specifically for cases like this. Here are my results.
---------------Monitor setup--------------- Laptop 1920 x 1080 Left external 1920 x 1200 (right of laptop) Right external 1920 x 1200 ---------------Ubuntu--------------- Booted docked with 2 ext monitors attached - success. Multiple monitors supported with display extended (rather than mirrored). This is the desired result. Undocked Windows correctly put on laptop display. This is the desired result. Re-docked Displays correctly detected, restored with correct placement Windows returned to external monitor. This is the desired result. ---------------Xubuntu--------------- Booted docked All monitors successfully detected, but displays mirrored rather than extended. Resolution of external monitors incorrectly set to be the same as the laptop resoluion. Went to Display settings to correct DP2 right of laptop - asked to keep settings but not done (clicked Keep) Set correct resolution - asked to keep settings but not done (clicked Keep) DP3 right of (laptop automatically selected) - asked to keep settings but not done (clicked Keep) DP3 right of DP2 - asked to keep settings but not done (clicked Keep) Set correct resolution - asked to keep settings (clicked Keep) Display was finally extended across all monitors with proper resolution. Undocked - Display was set only on the laptop as expected, but X became unresponsive before windows were moved to that display. Mouse movement was responding slowly & erratically. I waited a few minutes, but the situation did not change. I was able to get to a virtual terminal, eventually, with Ctrl-Alt-F1. I saw that kworker 0:2 was at 100% CPU utilization. Waited a few minutes & went back to X with Ctrl-Alt-F7. The laptop screen had white noise, the two external monitors had no display. Also, when booting into the live Xubuntu USB environment, after settings proper resolutions but *not* undocking, I saw similar corruption during a reboot. The laptop display again showed the white noise / lines when the external monitors showed the Xubuntu logo screen. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1267281 Title: Auto-detection of a monitor being added or removed not working Status in “xorg” package in Ubuntu: Incomplete Bug description: With my Lenovo W530 laptop, what is expected to happen is external displays are correctly detected when the laptop is docked (after being undocked). However, the user is not given the option to configure them. I have to go to nVidia-Settings to re-activate the display on the two external monitors.
