I’m using ATmega micros, on my Lily58. If I remember correctly, the default QMK behaviour was to use the USB to select which half was the master and what side it was on. That would work on RP2040 boards just as well so that may be what the provided firmware does.

I would suggest you just flash them both then see what they do. If they are swapped, try connecting the USB to the other half. If that works then you don’t have a problem. There’s no risk of damaging them and the RP2040 is pretty easy to reflash.

I wasn’t satisfied with that method and set QMK to store the sides in eeprom so I could use the same firmware but connect to either one. I’m not sure if the 2040 has a separate non-volatile memory so you’ll likely need a different method. I think a GPIO can be grounded to set the side but the Lily58 doesn’t do this. You could add a bodge wire if you want this but you have to customise QMK to use that method.

I just take a chip

Cheers.

I got an overpriced 250×200mm sheet off Amazon, just because it was easy. It’s definitely available cheaper elsewhere. I was trying to get blank black G10 / FR4 board to match the PCB but it doesn’t seem easily available in small quantities (except from China). I just searched for 1.6mm sheet and this stuff came up (it’s 0.06 inch but close enough). It cuts really well with a hacksaw - didn’t chip or crack at all and cleans up with a file or just a craft knife. I roughed it up the surface with sandpaper to CA glue it together and they’re holding together great.

The key cap set I got only had 1 and 1.5U. There are some 1.25U caps available separately online so I may well do that, thanks!

Is there any reason to keep the existing set-up? If it’s just one drive, you could replace it with another and install Alma or something fresh. Then you could copy over whatever config the old system had to get up and running again. You could swap to the old drive if you needed to revert. If you have a spare machine, you could stand up the fresh setup side-by-side with the old one before swapping over.

I find it odd, because venv is a “Suggested package”, actually. It isn’t in the list of new packages that will be installed with python3 by default.

I think the next major release of apt is supposed to be easier to read. Unless Debian neuter it.

It should use systemd-inhibit (or whatever the dmesg dbus service is) to tell the system it’s busy. How else would the system know?

Not every program or service on your system

Of course not, but plenty do when running a task where the user is unlikely to make inputs and also doesn’t want the machine to sleep. Firefox can call org.gnome.SessionManager.Inhibit over dbus with the “video-playing” description, same for VLC. Transmission can call that interface while a transfer is in progress (with a config toggle). It seems a pretty reasonable default for samba to do the same while a long-running file transfer is ongoing.

[Samba] doesn’t copy your files for you.

Sure but it has to know when a transfer is running. It would be nice to have the option to inhibit sleep if the transfer is runs for a significant amount of time.

For sure, I don’t know the internals of Samba, but surely the server knows that it’s serving a file no matter how the client accesses it. I don’t think a few dbus messages would cause issues.

I have my own service that looks at the network traffic via /proc and a few other things. That sends the system to sleep itself if everything looks truly idle.

I do think it would be nice for a file server like samba to inhibit sleep using the standard interface for it. But yeah, I appreciate there are complications, like video playback is presumably pulling a small extent of a file at a time, so there would have to be some kind of timer before releasing the inhibition or the system would sleep between transfers.

EDIT: I just took a look; with loglevel set to 3 for smb and smb2 I see log messages like:


<span style="color:#323232;">smbd_smb2_read: fnum 1712966762, file my_video.mkv, length=262144 offset=82366464 read=262144
</span>

These occur at most 10 seconds apart when playing a video over a share from another host. I don’t see why the smbd daemon couldn’t inhibit sleep untill smbd_smb2_read hasn’t run for a minute or so. You could have a script that monitors that log output and does this externally but it’d be nice to have built in.

Ah, that’s the misunderstanding. The original comment was talking about “watching something on another pc”. Like playing a video from a desktop PC on a laptop in another room. So it’s the samba server we want to prevent from sleeping, not the client. Yes it’d be nice to have a 24/7 media server set up, but for the simple case of sharing a file from one PC to another, it’d be nice for the server not to sleep in the middle of it by default.

I mean, we have systemd-bsod now…

Not that I’ve ever seen it of course.

Now you will never be able to quit vim!

I do use AltGr a load for composing non-ASCII characters. It’s currently my inner key where the joystick is. A bit of a stretch but writing C++ in vim pretty much requires the colon/semicolon key on the home row.

While true, you would have to change the firmware to swap column and row polarity if you reverse all the diodes e.g. #define DIODE_DIRECTION ROW2COL in QMK. Conventionally, QMK assumes rows are on the cathode side of the diodes and drives the columns high. ROW2COL reverses that so that the rows are driven high and columns scanned instead.

It’s best to stick to the convention so you avoid surprises.

Are you tying B9 high? By default, Gnd is right, Vcc is left. Unless there are pull-ups, both sides will act as slaves.

You can try just flipping that with #define SPLIT_HAND_PIN_LOW_IS_LEFT
