Re: Anyone else have problems with the panel (dock) after the Bullseye upgrade?

I had a problem with the Bullseye upgrade (upgraded from Buster) when running Xfce as my desktop environment where Xorg was hammering the CPU constantly (60-100% usage according to top) - my solution was to set a solid colour on the panel and not use the default setting (none - use system settings)....

Re: YouTube and h264ify on Pi 400 not working

Just updated my Pi 400 to the latest Chromium (92.0.4515.98~buster-rpt1) and I can confirm that hardware acceleration is working on Youtube videos (tested on 720p) and overall it seems snappier in general (i.e. when scrolling pages on forums) I've also noticed this version has the new idle detection...

Re: Problems Installing citrix Reciever

@TheBerryBoy From experience using Citrix on the Pi it's best to use the official ARMHF file from Citrix, however nsepa.deb is not available for ARM systems (I searched and searched and there's only versions for Windows and Intel/AMD based Linux PC's (https://support.citrix.com/article/CTX214394).

Re: Chromium Crash While Printing(Print Preview)

However a quick google provides a possible (if not ideal) solution which will disable the prin...

Re: Trim no longer working on Argon One M.2 case

I've got the same case and noticed trim didn't work so I contacted Argon40 (several months ago now) directly and found out that the current firmware used doesn't support trim and there's no ETA on when they will provide a version that will.

Cheers

What are you using to power the Pi 4B? get a normal SSD instead.... as use of these M.2 drives in RPi has been deemed "pointless" Crucial MX500 is a SATA M.2 SSD so the form-factor shouldn't matter (SATA is SATA whether it's 2.5 inch or M.2 or mSATA). Requires more current than the RPi ca...

It's an interesting idea - a bit like the Spectrum RAM pack.... You won't need a fan though, the Pi400 heat dissipation is fine as is.
