I’m getting the following error with the 5.11 RC2 candidate that I downloaded from the PV download site:
```auto
acbauer@hoth:~/Code/ParaView/ParaView-5.11.0-RC2-MPI-Linux-Python3.9-x86_64$ bin/paraview
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
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.
error: exception occurred: Subprocess aborted
```
I’ve set the environment variable for `export QT_QPA_PLATFORM=wayland` and checked the other typical environment variables (LD\_LIBRARY\_PATH, PYTHONPATH). This is on an Ubuntu machine. The ParaView-5.10.1-MPI-Linux-Python3.9-x86\_64 installed version works. Any idea what the issue is? Anything I should try out?
Thanks,
Andy

Which ubuntu version are you using ?
I wonder if this is caused by wayland.

I’m on Ubuntu 22.04.1 LTS.
Note that when I run the PV GUI from master on my machine (which runs successfully) I get the following similar message:
```auto
acbauer@hoth:~/Code/ParaView/debug$ bin/paraview
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
```
Also, `pvpython` from the RC2 installer works fine. I tested that with just rendering the Wavelet source. I suppose that makes sense though since this appears to be a Qt issue.

I’m unable to reproduce on my ubuntu 22.04 running wayland, with either rc1 or rc2.
Is your QT\_PLUGIN\_PATH env var set ?

Doesn’t look like it. I have:
```auto
acbauer@hoth:~$ env |grep QT
QT_ACCESSIBILITY=1
QT_IM_MODULE=ibus
```
I tried `paraview --dr` to see if it was anything in my registry either and I get the same issue. So I tried this which was interesting in that it failed before showing the command line options:
```auto
acbauer@hoth:~/Code/ParaView/ParaView-5.11.0-RC2-MPI-Linux-Python3.9-x86_64$ bin/paraview --help
Launcher options:
--print Print modified environment.
--system-mpi Use MPI implementation available on the system.
--mesa Use Mesa GL for rendering.
--backend Specify mesa backend.
Available backends:
llvmpipe
swr
paraview options:

At this point I have no idea. You should try on another computer.
Maybe @ben.boeckel or @cory.quammen have an idea.

The `xcb` plugin now requires way more libraries that might not be on minimal installations. I would recommend running with `LD_DEBUG=libs` to see what fails to load and installing the packages for those. The Fedora list includes:
- /usr/bin/glxinfo
- git
- mesa-dri-drivers
- mesa-libGL\*
- libXcursor-devel
- libxcrypt-compat
- libxkbcommon
- libxkbcommon-x11
- xcb-util-image
- xcb-util-wm
- xcb-util
- xcb-util-image
- xcb-util-keysyms
- xcb-util-renderutil
The `xcb` packages are likely of most interest here.

That was the fix. For me I had to install the following packages for Ubuntu:
- libxcb-xinerama0
- libxcb-xinput0
Thanks for the help!

Do we have a package list somewhere for the binary release ? This would be usefull.

Not to my knowledge. Is there a standard way to do this on linux? Maybe a ubuntu-setup.sh script that we package calls `apt install libxcb-*` and anything else required and describes these in a README?

Might be better to add it to the FAQ here on Discourse.

I would say no to a script, maintaining it will be a pain and it will be specific to each version of each distro.
Just a list of debian packages is fine, fancier distro user will be able to figure it out themselves.
This list should be were ParaView binary release user will find it, so discourse may be a good choice, but docs could be too.
