cannot start blender 3.3 Linux

When I try to start blender I get the message for security reasons launching executable is not allowed i this context.
I do not understand why I have already set the permission is allowed to is executable. With leap 15.3 it works perfect.

How do you start blender?
Post the complete command line using Code-Tags:

In addition to providing information about how you’re launching Blender - how did you install it? There are lots of options (Steam, Direct from, from the openSUSE repos).

I’ve run it on 15.4 and TW without issue - but I also typically install using Steam these days.

Updated Leap to current version:

Operating System: openSUSE Leap 15.4
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Kernel Version: 5.14.21-150400.24.21-default (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-6700K CPU @ 4.00GHz
Memory: 31.0 GiB of RAM
Graphics Processor: Mesa DRI Intel® HD Graphics 530

When typing “blender” on background of the desktop Blender 2.82 starts up as does any other application.

I need the latest blender 3.3 so i downloaded then i extracted the folder, opened the blender 3.3 folder and hit blender.
But then i get the message cannot open executable file for security reasons in this content. I have already set under permission excutable.

So, you went to and downloaded to your home directory, extracted the folder, and clicked on the executable. Is that about right? If so use sudo or su. While the package in your home directory is executable, it has to install to root level directories. In order to install to root level directories, you need sudo or su.

Did you read the installation instructions? Blender does’t need to install anything to root directories! Your claim is not backed by any facts. Runing this executable (GUI) as root is a really bad idea!

Use Tumbleweed instead of Leap 15.4. Tumbleweed has blender 3.3.

Also try to start blender from console:

cd <blender installation directory>

Your error message is a wide spread problem and can be caused by different things:


"Note Blender’s source code is available for free to either reference or to Build from Source. While normal users are not expected to compile Blender, it does have advantages:

  • Blender is always up to date.

  • It allows access to any version or branch where a feature is being developed.

  • It can be freely customized."

If you noted my initial comment I gave the link to the source package, hence the instructions. The other options are to install it via Steam or the openSUSE repos. karlmistelberger has said it is available via the repos. I suggest you use the repos.

There is not even the need to compile it from source as blender provides a downloadable archive (prominently on the download page) which you only have to unpack and run. And no, you didn’t provide the link to source code. The source code is on git as described in your last link. You pointed to the archive that you only have to unpack and run (unfortunately you pointed to a unknown mirror without checksums as they are provided at the real blender site).

That is true, but not everyone does that or follows directions.

Thanks su works for me

Glad to hear it

Just wondering why sudo or su is needed really.
I am using the tar.xz file from blender site and just untar it in one of my drive accessible to the user with no problem for a long time.
If want to be run directly, be sure it is in the path.

It seems to do with the directories in which it’s installed. On one hand you can install it to the home directory or to the /usr directory. It’s when it’s installed to the /usr directory that you would need sudo or su.

I could be wrong but depends on where in usr you install it then you don’t need the root permission to run it just like any other application we install using zypper or yast.
Nice to see you around, been a while I haven’t seen that gentoo avatar.:wink:
“Installing on Linux](
Check the Downloading Blender page to find the minimum requirements and where to get Blender (if you have not done so yet).
Install from]( Download the Linux version for your architecture and uncompress the file to the desired location (e.g. ~/software or /usr/local).”

Thank you. It has been a while. I’ve been thinking that a security overview should be updated. Especially with the coming of Web 3.0, where Web 3.0 is the newest version and based on blockchain and a decentralized web. But that’s another subject. It’s good to see my old friends again. I do think the best way to install blender is via Steam or Zypper and YaST.

I hope you stay around;)

Back to the subject, I extracted the tar.xz blender 3.3 file in /usr/local and I can run it by my user without needing the root permission.
And it found & uses my blender config in /home/conram/.config/blender

So what would happen if you delete your blender config, or at least make a backup of it?
