Gemini PDA - Linux / No 4G connection

« on: July 12, 2018, 04:33:18 pm »

I am finally getting around to trying to get mobile data connection going on my Gemini. But I am having no luck. To say that I have been struggling would be an overstatement, since I simply have gotten nowhere at all...

What happens when I try to power on cellular in cmst is that I get an error message saying:
Error Name: org.freedesktop.DBus.Error.UnknownObject
Error Message: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

So, ofono and/or connman has not registered stuff related to the cellular modem?
I really have no idea of where to go from here, and what to check for troubleshooting. I tried running ofonod in debug-log mode, and got a whole bunch of info...
When I just check the logs from ofono (with normal logging) I get:

And so on forever. What should I check to find out what is going on?

(Note, I did have to reflash my device completely once, but I believe that I got the NVRAM backup back into its correct place, see separate thread of mine)

Gemini PDA - Linux / Controlling brightness from other WMs

« on: July 07, 2018, 03:59:21 pm »

I'm trying to configure i3 to run on my Gemini, which may seem like a very strange thing to do, but I think that a keyboard-centric environment may turn out to be a really nice thing for the Gemini. Anyway, I am having trouble with the brightmess controls, and I'm wondering if anyone has any tips for me.

I have tried running the brightness control scripts that LxQt uses, but nothing happens. Looking a little bit deeper into them, I realize that they send dbus commands to the repowerd daemon. And looking at the logs:

repowerd[683]: g_dbus_connection_call_sync_internal: assertion 'object_path != NULL && g_variant_is_object_path (object_path)' failed
repowerd[683]: LogindSessionTracker: dbus_get_session_uid() failed to get session uid:

Sooo, something is going on with a logind uid?

I tried looking at the logs that repowerd spits out when i log into LxQt vs i3, and it appears that when I log into LxQt a lot of stuff happens, like logind/seat/dbus stuff. But when I log into i3, nothing. However, if I log in to LxQt and log out and into i3 without a reboot I get working brightness controls.

What is the magic that LxQt does, and how do i replicate it?

Gemini PDA - Linux / Incredible amounts of kernel logs

« on: July 07, 2018, 03:40:11 pm »

The amount of logs generated by the kernel in TP1 & TP2 is astounding. Is there any way to turn off or reduce these logs? They make the system log difficult to use for debugging other things...

Gemini PDA - Linux / Firmware flashing error: Invalid ROM or PMT address [SOLVED]

« on: June 27, 2018, 04:47:57 pm »

Oh, what have I done now?!

I was flashing TP2 and Android onto my gemini, and there was an error halfway through. So I tried again, and again, and again. But I keep getting "Invalid ROM or PMT address", no matter what I do.

If I remove the flash tool and the firmware directory and start over I first get another error message, something very unhelpful about "MSP ERROE Code: 0x00"
But if I then try again I get the Invalid... error again

I've tried to do an AndroidOnly flash, but then I get an error message about the partition table being wrong, and that I should select "Firmware Upgrade" and try again. Which I obviously already had selected...

What do I do? Do I need to do a reformat, somehow? And how do I do that safely?

Thanks
Lars

Gemini PDA - Linux / Differences between TP1 and TP2

« on: June 26, 2018, 06:40:06 am »

If I understand correctly there was a Technical Preview 2 of Debian released on the 22nd of June, but I have been unable to find any information about the differences between TP1 and TP2.
Should I reflash, or is a TP1 followed by a dist-upgrade and a kernel update the same as TP2?

Planet Computers news: http://support.planetcom.co.uk/index.php/Main_Page
Gemian wiki: https://github.com/gemian/gemini-keyboard-a.../wiki/DebianTP2

Is there a developer channel somewhere where things like this are discussed? The #gemini-pda irc channel I would assume to be mainly about Android.
