How to switch off cursor blink?

I can't work with a blinking cursor, so now I've now started to use Q4OS I want to stop the blinking. This is easy in Konsole, but I want to do it system-wide. I installed qt5ct but it has no effect, the reason being this error message:

The QT_QPA_PLATFORMTHEME environment variable is not set correctly (current value: q4ostde, required value: qt5ct).

Unfortunately, I don't know where to set this or even whether it is the right solution. I tried doing this in .profile:

export QT_QPA_PLATFORMTHEME=qt5ct

but that had no effect.

Is it possible to turn off cursor blink system-wide in Q4OS?

Quite a lot of people can't work with cursor blink, see  the website jurta.org/en/prog/noblink

Re: How to switch off cursor blink?

Well, the QT_QPA_PLATFORMTHEME=q4ostde is valid, it enables QT5 applications read and apply TDE settings. We don't recommend to change it, you will loose Q4OS functions and it will not modify cursor behavior.

In anyway you can export environment variables by adding a script in $HOME/.trinity/env/ folder.

Where do you experience blinking cursor in Q4OS Trinity, would you please post some examples ?

I added ~/.trinity/env/blink containing the single line
export QT_QPA_PLATFORMTHEME=qt5ct
and it had no effect after logging out & in again.

If you run Konquerer and click in the Location bar the cursor blinks.
If you go to the font settings and click Adjust All Fonts, then check the Size checkbox and click in the size spinner, the cursor blinks. Etc.

You also need to edit file /opt/trinity/env/50_q4loginscr01.sh to modify current variables.

Given you don't recommend changing the platform theme, how can I tell trinity to set the blink rate to 0?

We are not sure if this is even possible, so we recommend asking the Trinity desktop developers https://www.trinitydesktop.org/
