Porthole replacement available
With the loss of Porthole due to Portage dropping support for Python 2.x, it's been a tough time trying to update my Gentoo system using only the command line tools. It was such a drag that I finally wrote my own Porthole replacement, which you can find the source code of here . It doesn't use any l...

Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPi3B+ and RPi4B)
I knew this GenPi64 thing was too good to last. So sorry to see you go Sakaki. You did an amazing job and we were so lucky to have your talented help for so long. Thank you so much! I wish you the best of luck at your new job and hope life treats you well.

Re: Problems setting static IP address

Re: gdb "compile code" feature?
I wrote a very simple shell script to print the arguments and told gdb to use that as the compiler, which showed them ok. Then I thought, what if I call the compiler from my script? Lo and behold it compiled the code and gdb happily ran it! Wow, I had no idea to try something as crazy as that! Your...

gdb "compile code" feature?
Does anybody have a gcc/gdb combination installed that lets you use the gdb "compile code" feature successfully? This feature is supposed to let you write some C code on-the-fly while your app is running under the debugger, without requiring recompiling and restarting the app to test new c...

I bought 3 x USB 3.0 to SATA adapters on eBay. They all turned out to be JMicron based JMS578 devices with different firmware revisions. None of them worked worth a darn with my old Corsair FORCE 120GB SSD drive that I was hoping to use with the Raspberry Pi. Even with quirks enabled, it was still t...

Don't genup with ACCEPT_KEYWORDS="* ~*" !
So, admittedly, I'm a newbie at Gentoo. I was trying to get a version of FreeCell installed, any version, and was having a heck of a time finding anything that would work, as everything I tried seemed to be blocked by "keywords." After digging through Sakaki's documentation, I ended up add...

Thanks Sakaki. On the RPi Config Tool failing to launch on my system, I figured out why.

Unfortunately, the RPi Config Tool is sta...

How to disable pigpiod?
I installed Sakaki's excellent 64-bit Gentoo image on my Raspberry Pi 4 with 4GB RAM. Everything works so far, and it seems a lot more smooth, faster, responsive, etc than Raspbian. I'm looking to make this my daily driver now and ditching Raspbian, as it is just so much better. One thing I noticed ...

Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPi3B+ and RPi4B)
Not sure - I haven't noticed anything particularly egregious in day-to-day use, but the image does rely on many of the same display components as (a 64-bit kernel) Raspbian typically does (fkms etc). Do you have a particular example that definitely exhibits the tearing in Raspbian, so I can try it ...

Re: Extreame screen tearing on Raspberry Pi 4
So, I gave the compton compositor a try. And yes, it does "fix" the screen tearing issue on my Pi 4. But it seems to reduce overall screen drawing performance. Dragging windows feels a little laggy. Video playback seems a little laggy and perhaps even dropping frames... So, I think I prefe...

Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPi3B+ and RPi4B)
Forgive me if this has already been answered, but does this 64-bit Gentoo avoid the screen tearing issue that we see in Raspbian on Raspberry Pi 4? If so, how was the issue solved (if you know)? The screen tearing issue is the one thing I dislike about Raspbian and makes me want to give this Gentoo ...

Re: VLC in PI 4 - Opens in giant format beyond screen. Can't use it.
This is likely a problem with your monitor. I'm guessing you're using a TV that has an HDMI input. There are a number of such TV's that do not report correct physical screen size back to the computer. This messes up Qt's screen scaling calculations something awful. You can verify your monitor is mis...

One thing that might be relevant is alsa reports that the only format my Boss GT-1 supports is S32_LE at 44100 hz. Under Windows I can also run it a 48k and 96k. USB fundamentally operates off of a 48MHz clock and this is not adjustable. 48MHz can be evenly divided to serve a 48KHz or 96KHz audio s...

Re: Is Raspberry Pi 3 B+ better than Raspberry Pi 4 B for USB DACs?
I'm using USB audio (Burr-Brown Japan PCM2702) on a Pi 4 and it's seems plenty good to me. Audio quality is crisp and clear, no noticable noise issues other than a slightly annoying thwump sound when the Pi is rebooted or powered down. But I think that's the fault of my USB audio device, not Pi 4. U...

Why risk giving them even a few attempts before banning them? One thing I like doing is changing the port number that sshd runs on to something completely non-standard.
