I put an Intel SSD into an old Dell Inspiron N5110, installed Patience LXQt on it, and have everything but one item working as expected. I installed lxqt-sudo and I observed that it is linked to both "lxsu" and "lxsudo". So, using Alt-F2 "lxsu" I can start pcmanfm-qt or juffed with root privileges and it works great. But qterminal is different. Alt-F2 "lxsu qterminal" fails silently. Investigating, I was surprised to find that Alt-F2 "qterminal" actually opens qterminal with root privileges (the # prompt). Clicking on the dock icon for Qterminal opens it as a user with a $ prompt.
Obviously the laptop is fully usable with this configuration, but I decided to report it in case it is a bug, or a user error.
Thanks!
