Hello. These days more and more distributions are using Wayland. Last Ubuntu e.g. AFAIK Wayland design feature is that UI applications are not allowed to run as root.
From Subsurface manual: "If you are not root, you may not be a member of that group and won’t be able to use the USB port." Well, if you are root, you cannot run Subsurface under Wayland at all(?) Fortunately it's not necessary, but output doesn't look good. /usr/bin/subsurface --version Subsurface v4.7.1, built with libdivecomputer v0.6.0-devel-Subsurface- branch (0099aeeb7088c7ff3c4513f100b1cb5516f48233) sudo /usr/bin/subsurface QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime- root' No protocol specified QXcbConnection: Could not connect to display :0 Aborted sudo /usr/bin/subsurface --allow_run_as_root QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime- root' No protocol specified QXcbConnection: Could not connect to display :0 Aborted xhost +si:localuser:root sudo /usr/bin/subsurface QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime- root' You are running Subsurface as root. This is not recommended. If you insist to do so, run with option --allow_run_as_root. xhost +si:localuser:root sudo /usr/bin/subsurface --allow_run_as_root QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime- root' Runs OK. I would humbly suggest to detect Wayland and root privileges, show better command line message and quit. Or fix it somehow like GParted 0.30.0 did? Maybe we should mention it in the manual. Also --allow_run_as_root option is not mentioned in subsurface --help output nor in the manual.
