Debian 9.4.0 (Stretch) with LXQt - anyone experienced the same issues?

Question

I tried to install Debian Stretch (9.4.0) together with desktop environment LXQt.

Hereby I installed a raw and clean system without any additional packages first and then set the recommended and suggested packages to 0 via file /etc/apt/apt.conf.d/10noinstall-recommends.

Afterwards I installed the following (basic) packages via CLI:

xserver-xorg-core lxqt-core lightdm

---

1. After reboot into the fresh system first problem detected was the fact that my screen freezed during input of log-in data into lightdm. Hereby neither keyboard nor mouse pointer showed any reaction. This problem could be solved by installing the additional package xserver-xorg-input-libinput. Now log-in does not freeze anymore and will succeed.

2. Second problem was the issue that most of the graphical desktop environment icons are not getting displayed. Therefore I installed the package lxqt-qtplugin, but I could only reach the whole amount of icons when installing the additional icon theme package lxde-icon-theme. This by default integrated icon-theme adwaita-qt5 seems to have some problems I guess?

3. Third problem is the issue that common users (except root) do not have permissions to log-out, reboot, shutdown etc. the system. As a normal user clicking on the related buttons in the start menue does not have any effect. I am not yet sure how to fix this issue?

Did anyone of you experience similar issues? This did not appear on only one machine, the exactly same things happened when installing this combination into a VM. Maybe LXQt is more in a late beta state than fully reliable at present?

Answer 1

1. The first problem of freezing screen can be solved by installing the package xserver-xorg-input-libinput

2. Second problem could be solved by switching the icon theme to standard gnome theme, then it worked fine

3. Third problem was solved by installing the package lxqt-policykit which will install policykit-1 as a dependency

Answer 2

I use LXQt.

My install is normally

Standard system utilities

then

apt install xorg sudo chromium pulseaudio

and

sudo apt-get install lxde-core

I haven't tried just xserver-xorg-core

Interestingly he Manjaro site talks about using LXQt modules instead of LXQt-core

lxqt-config lxqt-panel lxqt-policykit lxqt-qtplugin lxqt-session lxqt-sudo pcmanfm-qt

It says

The following LXQt packages are not as important, install them when necessary. If you have doubts about the necessity of a package, install it:

lxqt-about lxqt-admin lxqt-globalkeys lxqt-notificationd lxqt-openssh-askpass lxqt-powermanagement lxqt-runner

There is also the idea that LXQt does not have a Windows Manager of its own and others can be used instead. I always install Openbox - although I never boot log into Openbox. e.g. https://github.com/lxqt/lxqt/wiki/ConfigWindowManagers

If I need to add apps I tend towards Qt applications https://wiki.manjaro.org/index.php?title=List_of_Qt_Applications and, althought I don't have to, I tend towards lightweight applications https://harbhag.wordpress.com/2010/07/02/best-lightweight-applications-for-linux/ (old but good).
