New Letos on Linux X11

[PRSoftware]

Hello,
I used SQLiteStudio on my Linux Mint 22.3 under X11.
I have downloaded the version 4.0.0 of Letos and uncompressed it.
When I try to launch the executable, I receive an error message :

qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb, wayland-brcm, wayland-egl, wayland.

Is Letos available for X11 or only for Wayland ?

This is not a Letos-specific issue, but a missing system dependency required by Qt 6.
Starting with Qt 6.5, the XCB platform plugin requires the libxcb-cursor0 library (or the equivalent package for your distribution).
On Linux Mint 22.3 (Ubuntu 24.04 based), please install it:

sudo apt update
sudo apt install libxcb-cursor0

If the problem persists, please also install the common Qt/XCB runtime dependencies:

sudo apt install \
    libxcb-cursor0 \
    libxkbcommon-x11-0 \
    libxcb-icccm4 \
    libxcb-keysyms1 \
    libxcb-image0 \
    libxcb-render-util0 \
    libxcb-xinerama0

If it still doesn't start, please run:

QT_DEBUG_PLUGINS=1 ./Letos

and send me the complete output.

Thanks a lot, the installation of libxcb-cursor0 solved the problem.
The new version seems good.

Same here, Linux Mint 22.3 under X11, installing libxcb-cursor0 did the trick!
