From 1a2adfedea74ae264eca7d4b8cbe6d1f04e552bf Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Wed, 1 Nov 2017 12:20:24 +0200 Subject: [PATCH] weston-launch: improve help text for -u and -t Explain that -u requires root and -t requires -u. Most importantly, document in what format does -t expect the tty to be given. It has been confusing, because Weston's --tty option takes an integer, weston-launch takes a full device path.
