Mandlebrot example displays no output

[Annirak]

I've just built the mandlebrot example, but I'm not getting any output. It just sits at the terminal, with a blinking cursor.

Matmul16 seems to work. As does aobench.

When I run matmul16's run_allnight variant, I get the occasional screen flicker. Likewise with mandlebrot. Could this be power related?

You did press alt-f1, and run it on a console window, as per the README?

(No, I didn't either....)

[Annirak]

I did read the readme... Twice. I must have missed the step because it's under build, not run...

I'll give it a try later today, though I'm still concerned about the flickering display.

I got it working with ctrl-alt-F2 to turn output on and ctrl-alt-F7 to go back to GUI.
I started it from a terminal window, if that makes a differance.
Pretty impressive graphics, though some flicker.

I wanted to test the mandelbrot example as well but realized that ctrl-alt-F2 [ or any other F-key] doesn`t do anything. What did i mess up?

Thank you Shodruky!
It works and Mandelbrot-example is quiet impressive!
But it would be much more comfortable if the ctrl-alt-function shortcut would work. Do you have an idea why it doesn't? I guess that there are lot of possible reasons why it doesn't work but what would be the most likely reason?

Thanks in advance!

I found an easier and more comfortable workaround for my problem without needing to actually stop lxdm:

I just open a virtual terminal:
sudo chvt 2
From there i can start the mandelbrot example.
To get back to lxdm without the need of restarting it:
sudo chvt 7
That might only work in the standard configuration- but hey it works!

Thanks! I didn't know that command.
