Re: Menu Bar missing

I started a terminal with Ctrl+Alt+T and in that I typed lxpanel and Enter. Then I got some menubar that looks different, but which contains the running programs and I can start new programs. This worked in Raspbian Buster. It is also possible to get to the running programs without a menu bar by usi...

Re: 8086tiny

8086tiny has the advantage that it can run in the terminal and that means you can paste in text from e.g. some web page.

Re: YouTube Videos in Chromium not Working on Raspberry Pi 4 B 4GB

I have 64 MB GPU RAM. Should I increase?

Edit: I increased to 128 MB GPU RAM and now both videos work here too.

I still wonder if h264ify is an advantage on Pi 4, or not.

Re: Raspberry Pi 4 Dual Monitors
