Re: Updated 64-bit Gentoo Image for RPi3 Released (now also for RPI3B+)

Great work on your Gentoo image, thanks.

I've used it to get Minecraft 1.13.2 working.

Do you know of a way to add additional video modes - ideally I would like to select 1280x720 ?

Hi rpiMike,

glad to hear you have found the image useful. Cool video btw ^-^

To your question, yes, the simplest way to select a video mode is to use the bundled configuration tool (which modifies the file /boot/config.txt). Simply click on Applications -> Settings -> RPi3 Config Tool, and a dialog similar [1] to the below will open:

Image

Choose either CEA or DMT in the HDMI group dropdown, and (if your display is well behaved), you should then be able to select from a list of supported modes in the HDMI mode dropdown. Once done, Click Save and Exit. You'll then be prompted whether to reboot - elect to do so (ensuring all work is saved first of course).

The system will then reboot into the specified video mode. If all is well, and your desktop is visible without artefacts post-reboot, elect to Keep the new settings in the dialog box that comes up automatically after boot. If however, for some reason, the new display mode is incompatible, simply wait and your system will automatically reboot after a minute, back into the original settings again (which, presumably, work).

You can read more about the video modes etc. in /boot/config.txt here, should you wish to edit the underlying configuration file manually (but, using the graphical tool is simpler and provides the simple fallback recovery in case a bad mode is selected).

hth,

sakaki

[1] This screenshot is actually of the previous version of the configuration tool, but the HDMI group / mode dropdowns are the same.

PS if you are running an older version of the image, you may not have the graphical config editor (shown above) available. If that is the case, you can install it as follows:

Code: Select all

[email protected] ~ $ sudo emaint sync --repo rpi3
[email protected] ~ $ sudo emerge -v sys-apps/pyconfig_gen

PPS if you haven't already, you'll get better graphical performance by turning display compositing off. You can do so from the Applications -> Settings -> Window Manager Tweaks tool (Compositor tab).

The v1.4.2 gentoo-on-rpi3-64bit image is now also available for install through PINN (called gentoo64 - and, for the PiTop v1 variant, gentoo64pt - there).

Just that pesky new Pi4 to port to now ^-^

Best, sakaki

Lol! It's never ending is it?
Looking forward to your 64-bit kernel for Buster/Pi4. :D
Great work as always.

Yep the Pi4 with dual screens and 4GB is now a serious developers box :D
Will be interesting to see how those WebGL samples runs now :lol:

I have been having trouble with 1.4.2 but it could be the cards or Etcher or even Win10.
Need to try writing cards on Linux box, just have not had time to track down the issue.

Did you get your issue with 1.4.2 resolved? I've double-checked that the version available for download on GitHub boots OK on a fresh install (on an RPi3B+ at any rate).

[Did you get your issue with 1.4.2 resolved?/quote]
Not yet, was going to try on the old home Linux box but it must be jealous of this new Pi4B1 and it decided to crash.
Also need to get some new uSD's if that was the issue.
Now I need to learn how to write SD's on Pi's.

But I'm really having way too much fun on this 4B1, wasting lots of time playing games that now work.
All in the interests of stress testing the 4 of course ;)

The 3B+ and Gentoo64 was borderline usable for native development.
I was only dabbling with this combo.

The Pi4 is so much better I now have very keen interest in a 64bit OS for it.
3D gaming and modelling now are possible and Vulkan too will work one day.
Blender seems ok, for the short time I tried it
My day job of designing PCBs is easier with two screens, can I do this on a 4?

Can a 4B4 compile kernels in a reasonable time?
It was slow with a 3B+ but so much has improved now.
A compiler cluster of 4B4's with faster USB and Ethernet, might get close to 12GB XEONs?

Moving to 64bit OS on 4 ,the speed increase means making a Desktop is much less painful.
So only a headless 64bit OS is needed to get going, hint ;)

Very fast and responsive on a remote Pi3B.
Looking forward to using the '64bit Gentoo ' on a remote Pi4B soon...
