STM32 Linux IDE display is SMALL on 4k screen

[David_]

Just download the latest version from ST web and installed Linux version of the STM32IDE tools chain.

It is Debian Linux 12, updated and upgraded. No hardware display card. Use the Intel i5 COP internal display card.

Display is small on 4k screen. If I switched to 2k resolution, display size is normal.

An idea on setting the software to expect a 4k screen? 

Many thanks

Hi David,

What do you mean with "Display is small"? Is text too tiny? Or the icons?

I had similiar issues some time ago with a GTK based window manager.

If nobody has a better idea I suggest:

1. If you use /opt/st/.../stm32cubeide then try /opt/st/.../stm32cubeide_wayland instead or vice versa.

2. In both cases you can play with environment variables GDK_SCALE and/or GDK_DPI_SCALE when starting /opt/st/.../stm32cubeide(_wayland)

Thanks for reply. Small sized display are 

(1) "pop up windows" (click MX, click on PB3 pins and it displays settings like input, output, or alternate functions ADC_IN2, SPI1_SCK, UART1_RTS) and

(2) the pinout configuration "menu selection vertical column of middle-left hand side"

Many thanks

Hi mfgkw,

Generally did you find that Linux version working well?  Should I use Windows 11 instead?

Many thanks

I use CubeIDE on Linux for years with Debian, Ubuntu and XUbuntu with icewm, KDE and Xface as windowmanager without big issues. I am glad not to be forced to windows ...

Only issue was that starting the IDE failed sometimes (hanging at the splash screen without any messages). There was a problem with a file leftover from previous runs. It took me some time to find a solution.

But besides of that it runs flawless, I have nothing to complain.

Only reason to use Windows could be TouchGFX, which does not run on Linux.
