From: Orestis Floros Date: Thu, 11 Oct 2018 20:19:21 +0000 (+0300) Subject: Close & reopen tray selwin when needed X-Git-Tag: 4.16~9^2 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=refs%2Fpull%2F3451%2Fhead;p=i3%2Fi3 Close & reopen tray selwin when needed Fixes #1329 Fixes #3317 (duplicate) Examples where the tray "disappeared": - Start without a "tray_output", reload config with "tray_output none", remove "tray_output none" and reload. - Start with "tray_output primary" (or "tray_output "), disable the primary output and then reconnect it.
