IDE Startup Memory

Hi all...

I have two computers, a desktop and a laptop (both late-model Intel). Both are running the same versions of Debian Linux with the KDE 'Plasma' desktop. The standard Arduino IDE (v 1.8.13) is running on both.

On one machine, at startup the Arduino IDE 'remembers' the last settings -i.e. window positions and sizes, file(s) currently open, etc.

On the other machine, the IDE DOES NOT remember any of that - i.e. it starts up with the small generic window, no file open.

Questions (probably stupid ones): Why are the two different? And how do I make the second one act like the first?

Thanx in advance for any response!

I don't have an answer, but I can provide some information that might be of use in finding the answer.

The relevant information is stored in the Arduino IDE's preferences file. You can find the location of that file by opening the Arduino IDE's File > Preferences and then checking the line following "** More preferences can be edited directly in the file"**.

Note that this preferences.txt file is only read when the IDE starts up, and only saved when the IDE is closed. Keep this in mind if you are reading or editing the file while the Arduino IDE is running.

My suggestion would be to open that preferences.txt file in a text editor to see whether the IDE wrote the relevant information to it correctly. It uses a key=value data format similar to an .ini file.

Thank you! Your comment steered me to the solution.

On machine #2 (no save) I would always end up with two IDE windows open... the original small 'no-file-open' window, and also a window, larger and positioned differently as I wanted.

All I had to do in this case is CLOSE the original small window before quitting altogether. The IDE then saves all the details of the newer window.

DOH! I knew it would be simple!
