[Bug 1260214] Re: 8086:0166 [ASUS TAICHI 21] External screen doesn't work.
My laptop is back, sorry it took so long.
One question here.
I'm trying to follow instructions provided here: https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream
But have no idea, who I should mail this report to.
Should it be HARDWARE MONITOR DRIVER maintainer? If it is, there like four or five maintainers, should I email them all?
