Thanks, will the green light be flashing if it is doing something?
If you are talking about a LED on the USB stick, I am not convinced it would flash when doing low level wear leveling and housekeeping. TYpically that light is used to indicate access activity at the user level.

Re: Raspberry PI 4 vs Smartphone

Looking at it another way, my smartphone regularly does 130 km/h whereas my Pi just sits on my desk, so "my" smartphone is much faster. But seriously now, it is an fairly non answerable question. You would need to quantify what your measurement of speed was to get a real answer. Having said that, a ...

Re: Installing unrar - nonfree on RPI4

You can just download the source and compile the nonfree version, which is the one you need for multi-part rar archives. It builds without issue on Buster. Not sure where I got the sources from but here is a starting point:

Re: Constant random crashes no consistent pattern

I suspect that it is more due to crap (seconds, wrong sizes, outright fakes) SD cards being sold online than anything else.

Works fine on Raspbian Lite with Mate. I don't see any reason why it should not work on Raspbian with LXDE.

Re: How to replace LXDE with Mate in Raspbian

I personally agree with you in terms of Mate versus LXDE. Of course I am biased since Mate is the Desktop I have chosen to run on all my Linux systems. However, I can understand why PRT chose LXDE. It is lighter (slightly) in terms of system load (which was more relevant for the older Pis) and simpl...

Re: Mini PC with DVD and HDD

It all depends on how much you care about the "packaging". I would strongly recommend a Pi 4 versus a 3B+. I have both and when used as a desktop compute the 4 is way faster/more usable. I would also recommend a SSD rather than a hard drive (faster, and less power hungry). If you are going to go Pi,...

Re: How to replace LXDE with Mate in Raspbian

"mate_desktop-environment" is the package that gets you the "standard" Mate desktop apps. You will also keep all of the LXDE "stuff". It will most likely be in the menus. Was that way last time I build a hybrid system. However, each Desktop has a slightly different idea of what goes where so the com...

Typically the USB 3.0 spec requires the ability to source 900 mA.

If the issue is that you broke pcmanfm by updating to the broken version (most likely case), you would have to rerun update to get the latest package list with the newer (fixed) version thus requiring:
