Hi,

First, I'm new on OpenFOAM, here is my problem: (I'm using WSL)

One month ago, I installed OpenFOAM v5 and all worked fine, but for what I have to do, I have to use OpenFOAM v7, so I uninstalled the v5 and installed v7 (I followed what is written here: https://openfoam.org/download/windows-10/ ).
Everything works until the command:

gedit &

Then I get the following message:

(gedit:555): GLib-GIO-CRITICAL **: 17:17:39.667: g_dbus_proxy_new_sync: assertion 'G_IS_DBUS_CONNECTION (connection)' failed

(gedit:555): dconf-WARNING **: 17:17:39.722: failed to commit changes to  dconf: Failed to execute child process “dbus-launch” (No such file or  directory)

(gedit:555): dconf-WARNING **: 17:17:39.734: failed to commit changes to  dconf: Failed to execute child process “dbus-launch” (No such file or  directory)

 (gedit:555): dconf-WARNING **: 17:17:42.907: failed to commit changes to  dconf: Failed to execute child process “dbus-launch” (No such file or  directory)

Well as I can't find what it means, I pursued and try the pitzDaily tutorial to see if it works. It seems that everything works except when I am trying to look at the results using command "paraFoam", I get the following message:

Created temporary 'pitzDaily.OpenFOAM'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-user'
failed to get the current screen resources

And then paraview (v5.6.0) opens, but it seems that my CPU is used for post processing instead of my GPU so it is extremely slow and I can't do anything.


My questions are:

1)how can I make paraview run on my GPU insted of CPU ?
2)what is the error message I get when writting "gedit & ", and what is the meaning of this command ?


Thank you for your time.

[Svetlana]

1. Is it this bug? They suggest to run "export DISPLAY=:0", and/or check what versions of packages are installed.
2. "&" sends the task to background. This means you can continue to use your terminal and run more commands while gedit is open. I believe the warnings from it are harmless: some minor gedit features pertaining to dbus (src - link to dbus at Wikipedia) may be unavailable.

[me45]

Yes this is this bug,

I have stricly followed the installation procedure

And so running "export DISPLAY=:0" changes nothing.


My Paraview version is 5.6.0

I have seen in paraview "about Paraview" that my OpenGL Rendere is : llvmpipe (LLVM 8.0, 128 bits) instead of the name of my GPU. My OpenGL version is 3.3 (Core profile) Mesa 18.3.4

Is it possible to change that ?

Could you possibly run "glxinfo" and post the output here?

[Svetlana]

What is your GPU? Do you have the GPU driver installed? If so, what package name or kernel module name?

[me45]

Sorry for late reply.
I have try to install the same version of OpenFoam on an other computer, I had the same trouble.
On my former laptot I had a chipset radeon r7
on the new one, nvidia geforce gtx 1050 (dedicated one) and chipset AMD Radeon Vega 8.
Yes I have drivers installed.
I don't know what is package name or kernel module name, is it driver version ?
