PCMANFM-QT as root

[electrovalent]

Hi,

When i try to run sudo pcmanfm-qt or lxqt-sudo pcmanfm-qt i get the following error.
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

I have debian 12 with LXQT.

Thanks in advance

You should not run X or Wayland applications as root. They can create files in your home directory that are owned by root. This will cause problems when you have normal applications that try to modify the same files and now suddenly cannot.

One of main Lxqt devs suggests me this trick under wayland:

Code: Select all

#!/bin/bash
xhost +SI:localuser:root
lxsu pcmanfm-qt
xhost -SI:localuser:root
exit

i use lxsu but you can replace with lxsudo, it allows me to launch root session under wayland like pcmanfm-qt or synaptic. Save it, make executable and launch it

Thanks @ttila,

Unfortunately this doesn't work under X.

Try the following:

Code: Select all

apt install lxqt-sudo dbus-x11
lxqt-sudo pcmanfm-qt

I didn't have dbus-x11 installed on my Debian Bookworm system, think that was the missing bit.
