Package: gtk3-nocsd Version: 3-1 Severity: minor In /etc/X11/Xsession.d/01gtk3-nocsd, there's the following comment about GTK_CSD:
# If this setting is left unset, it will default to 0 (CSD disabled) # unless GTK3_NOCSD_IGNORE is set to 1, in which case it will remain # unset. (With gtk defaulting to showing CSDs.) "in which case it will remain unset" is unclear. Perhaps add a reference to 51gtk3-nocsd-detect, where the default to 0 (except on GNOME desktops) actually occurs. -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.5.0-2-amd64 (SMP w/8 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gtk3-nocsd depends on: ii libgtk3-nocsd0 3-1 gtk3-nocsd recommends no packages. gtk3-nocsd suggests no packages. -- no debconf information
