lxqt-sudo is a graphical front-end of commands
su respectively. As such it enables regular users to launch applications with permissions of other users including root.
Compiling source code
Runtime dependencies are qtbase, sudo (su should be installed by default on all *ix operating systems) and liblxqt.
Installing at least one icon theme according to the XDG Icon Theme Specification like e. g. "Oxygen Icons" is recommended to have the GUI display icons.
Additional build dependencies are CMake and optionally Git to pull latest VCS checkouts. The localization files were outsourced to repository lxqt-l10n so the corresponding dependencies are needed, too. Please refer to this repository's
README.md for further information.
Code configuration is handled by CMake. CMake variable
CMAKE_INSTALL_PREFIX has to be set to
/usr on most operating systems.
To build run
make, to install
make install which accepts variable
DESTDIR as usual.
Official binary packages are provided by all major Linux distributions like Arch Linux, Debian (as of Debian stretch), Fedora and openSUSE. Just use your package manager to search for string
lxqt-sudo itself does not require any configuration.
In order to use it as front-end of
sudo the corresponding permissions have to be set, though. Most of the time this is handled by binary
visudo or editing configuration file
/etc/sudoers manually which both is beyond this document's scope.
lxqt-sudo comes with a man page explaining the syntax very well so running
man 1 lxqt-sudo should get you started.
sudo is used as backend, the choice can be enforced by command line options
--su[do] or by using symbolic links
lxsudo which belong to regular installations of lxqt-sudo.
