Re: Large mouse button latency

There are some funky interference issues with wifi, hdmi, usb 3.0 and usb 2.0 rf dongles. Easiest solution is move your usb 2.0 rf dongles away for the Pi vi a USB extender or potential a USB hub.

Re: New Raspberry Pi user. My RPI4 8 gig version wont boot up to desktop. Help please

You are likely going to have more success getting things sorted with a USB connected keyboard (wireless or corded). On first boot you need to run through the initial setup and I don't believe Bluetooth is enabled initially. See the following for more info: https://www.digikey.ca/en/maker/blogs/raspb...

Re: How to disable the "You have removed it without ejecting it" message?

Running Raspbian Lite + Mate, file manager is Caja, USB data sticks automount. If I use the "eject safely ..." menu pulldown in Caja or issue a "umount" command from a terminal, when I then remove the data stick there is no annoying and incorrect message. That points to it potentially being an inter...

Exactly the same experience as @pidd. Youtube is fine. Regular websites are fine. Very busy websites have issues with "aw snap". It does seem to somewhat correlate with cpu load.

Re: Which desktop would you like to be the future desktop of Raspberry Pi OS?

Definitely should add the current one as an explicit item. Beyond that I would argue that it does not matter. You have the standard desktop and you have Lite, where it is easy to add whatever desktop you want. Makes sense to keep a standard desktop across all models of Pi and given that you want to ...

Unfortunately plugging all devices into a common power bar will not really help, as with two-prong plugs you can simply rotate the plug 180 degrees, and switch the "hot" and "cold" wires to the plugged in device, meaning that there can still be a huge voltage difference between one device's chassis...

Re: Python script self terminate

It will stop/terminate if it runs to completion, or if you close the terminal without backgrounding the process. Beyond those observations you will need to supply more details, such as what OS, what script, how are you starting it, what are you expecting to happen, and what is happening.

Re: Netflix on Raspberry Pi 4

The fix is acquiring a current WideVine library (libwidevine.so). In theory you should be able to take it out of any 64 bit image. With an appropriate library and user agent string it should work. @ventz just extracted the library and packaged it all up nicely in a script.

Re: Netflix on Raspberry Pi 4

Are you sure you are running the "right" Chromium? The automated install script creates a second menu item called "Chromium (Media Edition)" that is running with the "right" user agent string.

It is working fine for me in Canada.

As far as I can tell Linux Reader is (as @Glowin the Dark suggests) just a reader. Safest way is either boot the Pi and then copy the files using a network aware process (scp, ftp, etc), or copy the files to a USB data stick and sneakernet them over to the Pi. You certainly can install software on W...

Re: Locate command in Bash

I am not a fan of tools that require maintenance of db to find stuff.

The advantage of "which" is that it uses your defined path. If "which" cannot find the command any shell script you run will not find it unless you use appropriately qualified paths.

I seriously doubt that your Pi has gone rogue so for some reason it is being told to take screenshots.

Second possibility: Your daughter has gone...
