Kai Mast: 1) As per the sticker of the monitor itself (not from the Bug Description, or the result of a terminal command), could you please provide the full monitor manufacturer and model?
2) Regarding how you have the monitor connected, is this straight into the computer's miniDP cable, mDP to something else adapter, etc.? 3) Did this issue start to happen after an update? If so, which and when precisely? ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Laptop sometimes doesn't detect external monitor + [Lenovo ThinkPad T440s] Laptop sometimes doesn't detect external monitor -- 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
