Yeah, it seems to get worse with every 5.4 LTS update. Worked almost flawless about some months ago (despite taking something from 30-60s to successfully connect). But I don't see a correlation to any commits. But now, it's almost impossible to connect successfully, it usually disconnects after a 1-2 minutes (coincidentally just when entering a game).
I usually also see messages like this: During use of the controller (probably around disconnect time): [ 5304.480502] Bluetooth: Unexpected continuation frame (len 52) When plugging the BT dongle: [ 5241.926752] Bluetooth: hci0: unexpected event for opcode 0x0000 While it's in a loop of constantly connecting and disconnecting: [ 1120.736530] Bluetooth: hci0: hardware error 0x58 [ 1120.923550] debugfs: File 'le_min_key_size' in directory 'hci0' already present!

Other BT devices seem to just work fine tho I don't use a lot of them and only occasionally. It seems that the Xbox One S firmware does something strange in the BT protocol. It also needs either ERTM disabled to connect. Alternatively, one can apply this patch to be able to use ERTM: https://github.com/kakra/linux/commit/c8b24d83f227a7fecfa9420d6756074e8f9b542c I'm also feeling there's some internal state getting messed up within the controller on each BT pairing: Results are not really reproducible. I managed to get it to work flawlessly one time (stable connection despite 20-30s connect handshake time), then purged my Bluetooth config from /var/lib, re-paired the controller and now it's a mess - still with the same kernel version. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1750146 Title: Xbox (One) Wireless Controller won't connect Status in gnome-control-center: Confirmed Status in Linux: Confirmed Status in gnome-control-center package in Ubuntu: Triaged Bug description: Xbox One Wireless Controllers (Model 1708) refuse to connect via bluetooth with Ubuntu 17.10 in the gnome-control-center. Placing the controller into pairing mode makes it visible on the Bluetooth Devices list and the device pairs, but does not make the full connection needed to pull the controller out of pairing mode. This renders my controller unusable with my Ubuntu PC unless I want to resort to using the wire (microUSB). Please fix. See the attached system information below.
