Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello all.

Quite enjoying my Linux journey so far, now that I have dropped Windoze totally.

Setting up Ventoy tonight, I ran into some problems.
The application(once unzipped), would simply not run.

Borrowing from recent knowledge of the power of the Linux terminal, I opened the terminal, and navigated to the download folder, and used my new Linux-Love: "./"

THIS WORKED, and the GUI then popped up, but the terminal was reporting some "CRITICAL" errors, but despite reading the messages several times, I am still lost as to what Linux is trying to tell me.

Can someone look at this screenshot, and tell me what Linux is upset about?

Despite Linux moaning about this, the application ran and completed fine, and I will now have a bit of a tinker about with it.

My God.....
A few years ago, I was so terrified of the Linux terminal, I would NOT run Linux.......just because of the fact the terminal existed at all.

But the Linux terminal, is pretty much the Windoze Command-prompt on steroids.
You DO have to be careful about what you do in the Linux terminal(as it is so powerful), but for general purpose "Hey Linux, I need to do this thing...." - I am falling more and more in love with it.

Just so long as I don't do anything silly with a SUDO command in the terminal, I SHOULD be OK.

Smoke makes things work. When the smoke gets out, it stops!

I web searched for
gtk_widget_grab_default gtk_widget_get_can_default failed

and it looks probably harmless plus may be due to running from the terminal.

You could set up a desktop item so it runs with a click or two.

Be careful of typing wildcards (the * character) with rm!! Unless you have rm -i it's risky if you're also a bit hamfisted with the space bar.

E.g. rm test.* or rm *.old are fine but a stray space would be a disaster.
