Re: Kernel sources correct version

I don't know which steps you used. Which model Pi is this for? How are you compiling the kernel? Are you even compiling a kernel? The 64-bit kernel is still experimental and not very well supported. I would guess you compiled a 32-bit kernel if compiling a kernel is even what you did or are aiming t...

Re: Kernel sources correct version

You might want to look up git clone documentation. You specified --depth=1 which means to only include the last (most recent) commit in the history, among other things. The current default branch (rpi-4.19.y) is many commits ahead (I'm not sure how many, but it's a lot) of the kernel version you wan...

You probably want something like this:

Code: Select all

git clone --depth=2500 https://github.com/raspberrypi/linux

Re: Keyboard shortcut to force minimize / force maximize the current app?

In addition to what jojopi said, it sounds like you might be using an old GTK2 application which wasn't designed for smaller screens or may be somewhat broken. I don't believe there is a way to force-maximize a window for an application like that. You might get better help if you mentioned which app...

The first test on whether camera works (not needed for you since you get still images) is seeing whether camera got detected: $ vcgencmd get_camera The next step in case of detected=1 for video is using this command to capture a 5s .h264 encoded video: $ raspivid -o tst.h264 In case you can play ts...

Glad to hear you got it working, Imightbejerry.

It has worked fine for me on my Samsung T5. Not sure what went wrong in your case.

I agree with you that periodic trim (instead of continuous trim) is probably the better way to go.
