Unfortunately nothing works. I had also problems with two other special programs. So I decided to downsize my resolution. I was surprised that it looks quite good if you choose the right resolution. This is not a real solution, but it is a workaround that I can live with very well.


Thank all of you for your support.

Hi Hani,

Thanks for your message.
This option has to be added to SCI/etc/jvm_options.xml file.

For more information about HiDPI display support and this specific option, see: https://gitlab.com/scilab/scilab/-/issues/13811

Best regards.

Subject: [Scilab-users] Big HiDPI issue with Scilab 2024.1.0 on Linux

I installed Scilab 2024.1.0 on a new notebook with a HiDPI display (1920x1080). It runs under Linux Mint 22 (Wilma) x86_64. I set up partial scaling to 125%. All other applications (except other "Javas") look properly scaled.

But Scilab do not. I installed the archive from scilab.org, not from the Mint/Ubuntu repository. It looks at least two times too small. Not only the text, the whole GUI: text, buttons, scroll bars, etc. I can barely read the menu. It is impossible to use it.

I know that this is a Java issue on Linux but that does not make it any better.

As a workaround, I know that you can start Java apps with the option

-Dsun.java2d.uiScale=2.0

to work around that issue. This works with Java apps I tested as long as you do not connect a normal DPI screen.

*But where do I have to insert that in the Scilab start script?*

I have not seen any line where Java was invoked.

Do any of you have a suggestion? Thanks in advance.

Regards, Hani
