Warning: Initializing MATLAB Graphics failed.
This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was:
MATLAB:hg:InvalidProperty
Unrecognized property screenpixelsperinch for class matlab.ui.Root.
> In hgrc (line 225)
In
matlab.graphics.internal.initialize (line 15)
When I first initialize the 2025b version on Ubuntu Linux, this error occured, I saw many posts about this are there any solutions for this issue? I tried starting with command:
matlab -softwareopengl

Hi Mert,
This can occur due to compatibility issues with graphics drivers, system libraries, or specific MATLAB settings. I understand that you’ve already updated Ubuntu to the latest version.
Here’s how you may resolve:
1. A graphic properties reset with:
reset(groot)
2. If this doesn’t work – try resetting MATLAB Preferences (rename the folder and then restart MATLAB):
mv ~/.matlab/R2025b ~/.matlab/R2025b_backup
3. OR See if it works in MATLAB 2025a or an earlier version.
If any of these don’t resolve your issue, please share the following:
  • Exact version of Ubuntu you are using
  • Check your logs( ~/.matlab/R2025b) and share the complete error message as well.
