Jani, my earlier comment was a false alarm. My apologies. I confirm that your patches work very well for my T440s with an Ultra Dock (firmware not updated). I tested with following two scenarios: 1. Booting while docked and then using xrandr to split the display. 2. Booting undocked and then dock and use xrandr to split the display. The changes worked well for both scenarios, albeit some minor delay which is very much acceptable. As mentioned by Tso earlier, there were some "*ERROR* too many retries, giving up" messages. Here are the dmesg outputs for the above two scenarios. https://bugs.freedesktop.org/attachment.cgi?id=93971 https://bugs.freedesktop.org/attachment.cgi?id=93972 This bug may now be closed.
