Matlab is freezing my Fedora 36 showing the error mentioned above.
This command “$ export DISPLAY=:0.0” worked for someone in Mathworks forum but hasn’t work for me. I am new to linux and really want to stick to Fedora but kinda need MATLAB for work.
Matlab is freezing my Fedora 36 showing the error mentioned above.
I do not use matlab, but have you read the ‘readme.txt’ and the ‘mathworks_installation_help.pdf’ file that are in the root directory where you extracted the zip file to do the install?
Did you configure the ‘installer_input.txt’ file in the same location before you did the install? If you did and you configured a log file as is available there then what does the log file show you?
What was the output of
echo $DISPLAY before you did the export command you show above? When running in a gui environment $DISPLAY should always have a value that refers to your existing desktop, and should not need to be changed. Matlab may need to link to that display but the value should not need changed.
The message you show seems to indicate that matlab is doing software rendering, which greatly increases CPU load and may make the system unresponsive and seem to freeze. What do you have for system hardware? Please post the output of
inxi -Fzxx in </> Preformatted text tags as available on the toolbar above this text input screen.
This is only relevant if you are running on xorg instead of Wayland. If you are running Xorg, you probably want
DISPLAY=:0, which specifies that you want to use the first running X session (it is possible, though not very common anymore to run multiple X sessions at one time). If you are running Wayland, then this setting won’t have any effect (except potentially confusing the application), since this is an Xorg specific workaround.
Yes, read both the help files but sadly no help there.
The install was only configured on matlab gui by changing the install directory.
I was having the same issue even before running the export command. echo is now 0.

I forgot to mention that I also had trouble during the installation with matlab gui not showing around and ran the following command
$ export LD_PRELOAD=/usr/lib64/libfreetype.so.6 e$ ./install
gui showed after this.
Thanks for the help in advance.
I see you are using Wayland. Have you tried logging in with xorg to see if there is a difference?
You also have a radeon GPU and the message is about opencl and software rendering. It may be that hardware rendering may need to be properly enabled to improve the support. IDK how to do that.
Unfortunately, that generally requires the proprietary amdgpu-pro bits that are a real pain to install in Fedora. There are a few topics here attempting it with mixed levels of success. As a Radeon user myself, I really wish this situation were different, but it’s the part of the driver AMD has yet to open source.
Same issue in xorg.
Try launching matlab from a terminal and see if there are any error messages.
