New Post: My First Week of Librem 5 Convergence

antonis · March 18, 2021, 3:24pm

@Kyle_Rankin Does the Baseus dock actually charge L5? Does it provide PD? Because the specs at some stores say something like USB-USB-C does not charge. Maybe this means something else, and I get confused.

Kyle_Rankin · March 18, 2021, 3:49pm

The dock I have does indeed charge the L5 while in use. Of course driving a monitor, keyboard and mouse does require more power from the Librem 5, so while the dock does charge the L5, it charges slowly compared to charging while undocked.

Given the L5’s weight it could well be brass already

I ordered this one via the “official” Baseus ebay store and it was 23€ including shipping.

How did you get the red LED to stop blinking with the battery out?

I didn’t; it blinks incessantly. At first it was distracting, but after awhile I didn’t notice it.

I just answered the same question on Matrix, so let me copy that:

there is a bq25895 register that tells it to disable the status LED
https://www.ti.com/lit/ds/symlink/bq25895.pdf
page 39, REG07, bit 6 - STAT_DIS
take care though, other bits in this register seem pretty dangerous.
in any case, sudo i2cget -f -y 3 0x6a 0x07 will give you the current value of the register
and you can set a new value with sudo i2cset -f -y 3 0x6a 0x07 <VALUE>
so in this case you would read the current value, set bit 6 and write it back.
just triple check that you change the correct bit
as long as you’re sure you set the value correctly it should be fine.
it would get problematic if you, say, cleared the wrong bit and forgot about it.
and after a while it turns out that you disabled Charging Safety Timer which won’t be able to ensure safety anymore
so, as a example:

purism@librem5:~$ sudo i2cget -f -y 3 0x6a 0x07
0x8d
purism@librem5:~$ sudo i2cset -f -y 3 0x6a 0x07 0xcd # turns STAT LED off
purism@librem5:~$ sudo i2cset -f -y 3 0x6a 0x07 0x8d # turns STAT LED back on

3 is the i2c bus number, 0x6a is the device address, and 0x07 is the register address.
the idea was that you read the current value (which turned out to be 0x8d on my device), then you set its 6th bit which results in 0xcd which you then write back to the register

irvinewade · March 22, 2021, 3:01am

What was that about triple checking? The example commands are correct but the associated text is erroneous - and exactly the kind of thing that you are warning about.

dos · March 22, 2021, 3:16am

Ha!

Edited, thanks

Hi I’m trying to use the Kensington SD4600P docking station with my Liberm 5 dogwood, but it seems not to detect convergence mode. Do I need to do something in the terminal to make the mode active? Is there a way to force it to become active if not?

Kyle_Rankin · March 24, 2021, 7:21pm

Not every USB-C dock happens to work with the Librem 5. My understanding is that USB-C PD negotiation implementations run all over the map and that the USB-C standard in general is kind of a mess.

irvinewade · March 24, 2021, 11:33pm

I’ve wondered about this too but my dock is still stuck in the Suez Canal.

Two questions:

are you running the latest software?
what is the USB vendor and product id of your dock?

I too wonder what the exact conditions are that have to be met in order for the Librem 5 to go into ‘Docked’ mode (because it didn’t work when I tried it with the hardware that I had to hand).

Kyle_Rankin · March 25, 2021, 3:36pm

The Librem 5 needs to detect the USB keyboard and mouse, and ideally also the USB-C Display Port display (but I’ve noticed on docks where the keyboard and mouse don’t work simultaneously with the display that it enters “docked mode” just with keyboard and mouse). Sometimes the negotiation with a particular USB-C hub doesn’t work and you only get one or the other. Other times you may get both but not Power Delivery. It really depends on the hub.

irvinewade · March 25, 2021, 9:35pm

So if I have a Bluetooth keyboard and mouse (which I do, and they work with the Librem 5) and I use it directly with a USB-C DisplayPort display (no need for a dock / hub / anything else, and the display does ‘work’ with the Librem 5), the Librem 5 won’t work out-of-the-box to enter “docked mode”?

I can live with this. I have an actual dock on order. I’m just exploring what is supposed to work and what is supposed not to work (at the current time).

Kyle_Rankin · March 25, 2021, 9:37pm

As an update, I started evaluating a generic 360 degree-style laptop dock that looks pretty similar to pictures I’ve seen of the Nexdock 360. It turns out it works out of the box with the Librem 5 without a hub in between. I already mounted an after-market magnetic phone mount to it so I can mount the Librem 5 next to the screen:

I’ve only been using it for a couple days but I’m already pretty pleased with it. At the moment power delivery only negotiated 500mA so the Librem 5 does lose some charge over time (instead of being charged) but it’s of course much slower a discharge than when it’s not plugged into the dock.

Kyle_Rankin · March 25, 2021, 9:38pm

Hmm I’m not sure in that scenario. There is a button on the top bar that lets you toggle docked mode in case it doesn’t happen automatically.

irvinewade · March 25, 2021, 10:05pm

Actually, I just tested it - and it does enter “docked mode” - but I couldn’t get it to work properly.

Is that button (Undocked / Docked) at the top actually a button, or just a display?

Kyle_Rankin · March 25, 2021, 10:07pm

Hmm, I think when it’s enabled you can use it as a button to disable it. I do also think there is some command you can run to enter docked mode (which essentially disables having windows automatically go full screen), but I don’t have it handy.

You can also control Display settings in Gnome Control Center.

dylanlesterpvcs · April 9, 2021, 4:24am

After further testing on my part I’ve found that my dogwood will crash when trying to enter docked mode with my dock. The dock is a Kensington SD4600P USB-C dock. Serial No B1802B002177. The dock powers the Librem 5, the Librem 5 crashes when plugged into it with a mouse and keyboard plugged in.
