![]() The results from these tests on the Raspberry Pi 4 and 400 were good (well, except for the Pi 400 Wi-Fi), and the Kali download page says that these images should work on the Pi 3, so I decided to give that a try too. Shutting down and switching from the 64-bit card to the 32-bit card produced results that were consistent with what I have seen so far – it boots and runs, performance is good overall, but Wi-Fi doesn't work, and there is no audio output. (Interesting note: lshw is not installed by default, but it can easily be installed on the 64-bit version with sudo apt install lshw, but not on the 32-bit version – apparently it isn't in the 32-bit repositories but it is in the 64-bit repositories.) I spent quite a lot of time trying to figure this out, with no success: apparently there is some sort of hardware difference between the Pi 4 and the Pi 400, but I can't figure out what. There is no wireless adapter or wireless networks shown in the drop-down from the Network Manager applet, there is no wireless adapter shown in the ip address output, there is no wireless device shown in the rfkill output, and there is no wireless adapter shown in the lshw output. This worked perfectly on the Pi 4, but it simply doesn't show up on the Pi 400. Second, and much more serious, the wireless networking adapter is not detected on the Raspberry Pi 400. I have no explanation for this, but as long as it works, I don't particularly care. The first was puzzling, but not particularly serious – the keyboard layout is correct, with none of the quirks that I struggled with on the Raspberry Pi 4. When I checked the configuration, I found two differences. ![]() Running through the same few tests as I had done on the Pi 4, everything seemed to be OK, including audio working in Firefox. That's already good news, because at least one of the other Linux distributions I have tested didn't boot in the 400. ![]() I took the microSD card with the 64-bit distribution and put it in the Pi 400, and it booted right up. With testing done on the Raspberry Pi 4, I moved on to the Pi 400. The second difference, and the much more pleasant one, is that audio works in Firefox! Again, I have tried this several ways, and bounced back and forth between the 32-bit and 64-bit versions, and it is consistent – no audio in the 32-bit version, but it works in the 64-bit version. I know that sounds weird, but I have tried this several times, in several different ways, and it is always like this – and only on the 64-bit version. Simply changing the system default in /etc/default/keyboard does not produce the correct layout in the desktop GUI going to Settings / Keyboard and changing the layout there works, but only until the next reboot but adding the desired layout twice in the Keyboard Settings causes the setting to be retained across reboots. First, keyboard layout configuration is inconsistent. I went through the same checks and tests as I had done for the 32-bit version, with mostly the same results – but two significant surprises. The difference in architecture can be confirmed with uname -a, which says aarch64 this time. Download, copy to microSD and initial boot were all identical to the 32-bit process. With the 32-bit version working very well, I decided to move on to the 64-bit version. ![]() SEE: An IT pro's guide to robotic process automation (free PDF) (TechRepublic) The default terminal emulator in the Favorites section is QTerminal, which is typical for an xfce distribution but looking in the Usual Applications / System list, I see that the QTerminal drop-down is there, which I prefer so that there is always a terminal available on the F12 key, and UXTerm and XTerm are also included.Ī quick check with uname -a shows that the Linux kernel is 4.19.118, and the 32-bit architecture is identified with armv7l. The only problem I ran into here was that audio doesn't seem to work, which I had already come across with openSUSE on the Pi 4, so I assume this is a more general problem that is likely to be fixed in a future release. I actually used Firefox on the Pi 4 to write portions of this post, and the performance was very good, with none of the lagging or difficulty that I have experienced on earlier Raspberry Pi / Browser combinations. Again, it has been customized for Kali, with a bookmark toolbar containing a useful group of items. The default web browser is Firefox ESR, and my first impression is that it starts very quickly for a Raspberry Pi system – even for a Pi 4, in fact.
