[Bug 1713311] Re: Unable to launch applications which use su-to-root from menu package as root on Wayland session

[Miroslav Kravec]

In unreleased version, HW access will be performed via D-Bus daemon. No
need to run ddccontrol/gddccontrol with root privileges. See
https://github.com/ddccontrol/ddccontrol/blob/master/CHANGELOG.md

However, as daemon is long running process. It needs a bit of polishing,
especially, get rid of memory leaks,... This is still in progress.

** Changed in: ddccontrol (Ubuntu)
       Status: New => In Progress

  ************************************************************

  Steps to reproduce:
  1. Install Ubuntu 17.10
  2. Install application from above list and menu package (if missed, for zenmap, see bug 1713274) - full list from - https://codesearch.debian.net/search?q=Exec%3Dsu-to-root+filetype%3Adesktop+path%3A*%2Fapplications%2F*&perpkg=1 , https://codesearch.debian.net/search?q=Exec%3Dgksudo+filetype%3Adesktop+path%3A*%2Fapplications%2F* and https://codesearch.debian.net/search?q=Exec%3Dgksu+filetype%3Adesktop+path%3A*%2Fapplications%2F* .

  3. Try to launch $APP_NAME from shortcut
  4. Get error window:
  Failed to run $APP_NAME as user root.
  Unable to copy the user's Xauthorization file.

  Expected results:
  * $APP_NAME may be run as root

  Actual results:
  * unable to run $APP_NAME as root

  Additional info:
  $ xhost
  access control enabled, only authorized clients can connect
  SI:localuser:artful

  $ export | grep "SESSION\|DESK"
  declare -x DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus"
  declare -x DESKTOP_AUTOSTART_ID="1082dacfd3a20e972150382958079482700000012280008"
  declare -x DESKTOP_SESSION="gnome"
  declare -x GDMSESSION="gnome"
  declare -x GNOME_DESKTOP_SESSION_ID="this-is-deprecated"
  declare -x SESSION_MANAGER="local/artful:@/tmp/.ICE-unix/1228,unix/artful:/tmp/.ICE-unix/1228"
  declare -x XDG_CURRENT_DESKTOP="GNOME"
  declare -x XDG_SESSION_DESKTOP="gnome"
  declare -x XDG_SESSION_ID="2"
  declare -x XDG_SESSION_TYPE="wayland"

  and this operations does not help:

  artful at artful:~$ xhost +si:localuser:root
  localuser:root being added to access control list
  artful at artful:~$ gksudo zenmap
  Error copying '/home/artful/.Xauthority' to '/tmp/libgksu-AgXCxW': No such file or directory
