Strange though, I did not have this problem at all in 18.04. Only occurred now after upgrading to 18.10. What changed? The kernel patch linked to is from 2016, and a lot of the other bug reports are older as well. Is it a regression of a sort?
I have a Thinkpad X270 (latest BiOS - 1.33) and this is driving me nuts. Luckily I came across this bug report so I'll at least have a couple of workarounds to try out :) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1552040 Title: [Lenovo ThinkPad T440s] Laptop sometimes doesn't detect external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1552040/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
