This may be a stupid question, but how can I install lxqt alongside gnome ?
Do I have to pay attention to anything special ?
Install a VM and have fun installing any desktop you want. You should always avoid having more than one DE on a system as there can be issues with library’s and other things.

Personally I live by the motto:
One system, One Desktop
If I am interested in trying out a desktop environment, I’ll do it in a Virtual Machine.
If I am really interested in a desktop environment, I dedicate some space on my disk to it in a new installation.

before you install lxqt udate your System
First, ensure your system is up-to-date by running:
sudo pacman -Syu
1: Install LXQt Packages
Install the LXQt desktop environment and necessary components:
sudo pacman -S lxqt lxqt-config lxqt-policykit lxqt-powermanagement
step 2: Install Display Manager (Optional)
sudo pacman -S lightdm lightdm-gtk-greeter
step3: Enable and start the lightdm service:
sudo systemctl enable lightdm
sudo systemctl start lightdm
Step 4: Configure Display Manager (Optional)
If you installed lightdm, edit its configuration file to choose your default desktop environment. Edit /etc/lightdm/lightdm.conf:
[Seat:*]
greeter-session=lightdm-gtk-greeter
user-session=lxqt # Set to lxqt or gnome
dont need for lightdm 
Many thanks for the answer
gdm is gnome, only make issues if you use lightdm
oh
