under systemd based distros i would recomend a mount unit and an automount unit (man systemd.mount and man system.automount) once set up, this will mount he directory of choice on demand without entering user details

as an alternative 'udisk2' can be used that consists of a daemon and cli util and has native support in gnome to allow you to mount and unmount partitions

both will avoid the boot issue you described. i would recommend the udisk method for removable devices such as usb sticks and the auto mount for builtin storage such as the micro sd card slot, i frequently use this for network filesystems when coupled with the auto unmount options

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

Not a strange thing to do at all! I'm running stumpwm on mine. Makes full use of the screen with nothing wasted and having a keyboard is perfect for this wm.

In any case, I have the same problem as you. I've not figured out how lxqt does it. What I have figured out is that you can adjust the brightness manually by changing the value in /sys/class/leds/lcd-backlight/brightness. The value should be an integer in the range 1-255. I am writing a shell script to do this but it needs root access. I'm getting around this by using sudo within the script and having my account set up so that it does need a password to invoke sudo.


One thing i do at my end is use the command 'id' to see if the script is being run as root and if not rexec the script via sudo meaning i do not have to worry about which comamnds need to be runa s root and which do not there are also some more subtle security issues this can fix but they are more of a concern for the environment i was working in with hostile users with high skll levels

the trick i use on my own systems is to use tmpfiled from systemd to change the group owner of the brightness file to that of the 'input' user that is avialbie on most modern distros and already have my user added to that group allowing myself access without root privileges

i stole the chromebook backlight animations and converted them to a cli script at http://blitz.works/text11/file/b405360ab31...11/backlight.py may need some work to update paths to point ot the LED backlight but if there is a brightness file that is autodetected i would recommend using that one rather than the LED one

Second incident, the bad news: my pinky was bitten when closing the lid, near the hinge. Visible damage consists of a 5mm blood blister on the inside of the 2nd pinky joint. Invisible damage included the shouting of nasty words within ear distance of young children.


Old Sapjaw strikes again, also had bloodblister

I know it is supposed to be a design point of the phone but i have found it to be one of the most annoying features, due to drawing blood and preventing me from easily setting he angling of the screen like a normal friction stop would do.

I use the logitech MX Ergo, i do have a m570 but the ergo is significantly nicer to use day to day to the point i was carrying it to and from work. Defiently worth the extra cost. the m570 only makes sense to me if you are unsure if you want a trackball or not.

have used it with the gemini and it works fine and being able to pair with 2 devices and switch between them has been nice when the laptop is around

While going through my RSS feeds this landed in my lap

MALI Driver

the TL;DR is that someone is working on mali GPU drivers for linux

It would appears that there is ongoing work (Post-lima) to have OSS graphics drivers. this is for the T860 and not the T880 as is in the x25/X27 however the difference between these chips is mainly the amount of cores and should just be a simple a matter of testing and perhaps updating a constant or two

Based on the authors blog posts work seems to be happening at a quick pace and so i am hopeful there should be something usable in the coming months

cant wait till there is something i can run on my chromebooks and phone

Suggestion:

It occurred to me after hearing Dr. Janko mention one side
of the Gemini's USB ports supported being used in "slave"
mode, that it would be great if they'd provide an app
(driver?) which would allow for the Gemini to be used as a
USB MassStorage device.

Like the original Android phones did, before they pulled
the functionality in ~v1.5-1.6.



Was poking around with this earlier, try enabling dev mode by going to the about phone apge and tapping the version 7-8 times, you then have the option of specifying what the device shows up as when attached. i have tried it with the network adapter without luck but that may be a driver issue

Interestingly the binaries i pull off the site have different hashes

i did note a trustzone binary in there which if we are lucky means the hardware visualization stuff is in there, poking around the arm github pages points to some alternate implementations but it will all depend on if it needs to be signed. with any luck planetcom has he keys to the kingdom and not mediatek

QUOTE
What is the significance of getting access to the UART module?


Helpful but not a major blocker, there are other ways to get data off the device and its common to have a serial via the usb connection if you have a special cable.

QUOTE
MediaTech is selling a dev board with the X20 on it.
https://www.mediatek.com/products/developme...-board-96boards
The dev board does not mention any GSM connectivity, although the X20 it self does
https://www.mediatek.com/products/smartphon...t6797-helio-x20


Our dev board is essentially the gemini itself, there will be enough differences that it will likely not be much of a gain to use a working dev board as these boards allow you to start software work before you have the hardware. as the gemini is delivered already we have the hardware to test on.

QUOTE
I have not played with a SoC dev board before. Does anyone have experience with a SoC api?
Do they give a well documented library that gives us full access to their hardware?
Why do companies like this not want to freely give out a well documented library for users to play with? I would like to be able to just go on their website and download this library.
How does a company like Planet Computers go about developing for a SoC? They have to sign NDA? A non public dev board for the X27 exists or the X family is so similar you just use the same code.

When you say there is no upstream support, what this means is that MediaTech has not submitted any code/drivers to the linux kernel that drives their hardware. Is this correct?

Please help me understand how this scene works.


Kernel development is a bit different to userspace development, there is no 'library' that we can drop in and use, and the quality of most chip vendors code is questionable at best. The major problems are that the 3.19 kernel is real old and has diverged significantly, in addition the android 3.19 kernel had a large amount of custom written parts in it that diverged from the base 3.19

There are some things we can leverage cross vendor, eg cpufreq stuff and some graphical/GPU stuff as this is mostly licesed cores that only really diffre by locaiton in memory. In addition the armv8 series came up with a spec that is sort of like the PC-XT spec and standardizes armv8 designs allowing a lot of power and boot code to be reused. the real issues will include the following

* Board specif cbring up
* memory timings
* SD reader driver
* usb type c drivers (still in flux in 4.15, will not really be stable 100% complete till 4.18 or end of this year)
* wif drivers (MT7610U/USB is supported but not confirmed this is the chip we use)
* 4g modem
* Keyboard driver
* IIO Sensors (gyroscope/compuss)

even once we do get access to the source (if we do) this si not going to be a simple copy and paste job and will likely be without vendor documentation

I would have paid 2x the current costs for an exynos based chip as i know samsung upstreams their drivers in mainline before devices hit production making ti a very simple affair to get a newer kernel working. there also would not be these limitations with the usb ports and chargng/displaying whihc is one of the major points of contention for me.

(mainline means that the kernels on kernel.org contain the drivers required to run the board)

still poking things at my end and hope to come up with a todo list soon but if anyone has a link to the kernel sources and is willing to share let me know as there are some drivers i would not mind having on hand

Hi

I have tried a 128GD exFAT microSD in my Gemini but its not recognised and asks me to format it. I am not keen as it contains data. Does anyone know the file system that Gemini needs for storage? FAT32?


Just formated a 256GB card i had laying around and set it as the internal storage and everything appears to be working once i migrated data across (used internal mode for sd card not external)

Did anyone maybe test if putty or any other SSH client behaves well on the Gemini and its keyboard?


Just got mine about 8 hours ago and put about an hour into the keyboard. Once i screwed around with the keyboard settings so i could actually type "@" it was a fairly good thumb experience, for the extra characters you can hit the planet + , key to bring up the stnadard google keyboard (or any other installed keyboard) and this defaults to special symbols

I have yet to do some coding on this and while i wont be at full speed (and do not expect to) it is infinetly more usable than the built in touch screen keyboards of other machines

the plnet bar includes a link for juicessh which i happened to have purchased recently due to how happy i was with it for humb typing

Hi

It has been many years but after looking further into the technical information around the gemini i found that not only is oesf.org back up and running, but it seems to be the center for a lot of gemini discussion

For those who don't remember me, i (attempted) to kick off the pocket penguin (gemini like and beyond my skill level) and posted continuously (Looks like i am still in the top #10 highest posters)

The last couple of years has seen me compiling bleeding edge linux kernels and patching them to get kernel.org/Mainline kernels running on chromebooks and documenting this where appropriate. I plan to do similar things for the gemini.

Looking forward to getting everything working.

i have a kohjinsha thats the same as the peperpad v3. i would say its zippier than most people expect and i dont have to worry about turning it off for a 100M dash (all solid state now wink.gif)

if you have something i can compile to test how fast it is i can do that for you, note that i dont have an arm compiler for it atm so it may effect results.

bluetooth and wifi built in, get one with a broken screen and you are in buisness. keep it in the bag left on (its low heat) and just charge it when you get to work (i get 4 hrs minimum on one charge)

looks great till you add up the price with all the features and the mark up on single units (2.5x) wink.gif

work is under way, there is a new guy on board who i have been talking to and has really gotten the ball rolling again, time will tell.

i think by the time its done there will be more powerful units but i think the feature set of this design will make up for it, that and the curveballs i am throwing into the design, as i have said in private i am building this machine to last. i refuse to skimp on the quality of components

of course wait till i produce somthing first at the moment im all talk

dont know if its an option but cant you write a wrapper script to scp to your home pc, compile there and then rsync the data back?

there are days when my Z or kohjinsha are underpowered and i just use a 3G mobile with a data plan to connect to my home PC for heavy lifting

i might be able to whip somthing up for you using rsync and ssh if you want

*** EDIT ***

Noticed the low reception problem, ignore post, seems i came up with the same ideas everyone else did

unless you want a beowolf of 1000's wink.gif i mean who wouldnt

or baring that, a debian slug cluster and distcc, they chew a bit of power but with a bit of modification you can get the boot time down to where you only need to turn it on when you need to

if you have a wince mobile then look out for the internet sharing program, connecting to that over bluetooth is as simple as

pand -c <bt mac>
/sbin/dhclient bnep0

its great if you dont want to fiddle with dial strings

it sounds like your best off contacting me directtly

the qemu stuff sounds alright but writing saftware to emulate the hardware would be more work than neessacry, i would rather spend more cash on hardware and push out several prototypes

as for your needs, it almost looks like a subset of what i had in mind wink.gif i had planned to attach a CF card off of the ATA interface but with the way that SD cards are going it might be even better for me to drop that and go SD for the root FS. ethier way it wouldnt be too hard to have both

just PM me and i will send you more details about how to contact me

most of the schematic is in my head still, at the moment learning geda is my biggest priority ever scince i learnt that it does have autorouting

i am not 100% sure what you meant by the qemu, if you meant connecting the chips to a qemu processor through a bus or writing drivers for each chip to confirm that the drivers on the virtual cpu work

ethier way it looked like to much work for too little gain

feel free to contact me through alternative means if you want, also would you mind filling out teh details on your media player?

as i said most of the good zytel modems allow for a backup wan line, you basically need one of them and another modem that automatically logs in on the modem side and gets an ip from dhcp on the lan side

you the zytel where the backup wan line is (ie ip address ) and if the line drops it reroutes packets, note that this can be a BAD thing with long running sessions as your external IP address will change meaning things like msn, yahoo chat, ssh, skype and ongoing SIP calls will drop

in the case of ssh once the primary line comes back up as long as you didnt close the sesion all will resumae as nothing happened but its best not to rely on that

not sure what you mean by distributing the two lines, do you mean bond the lines together for high avalability and or more bandwidth, if so some of the zytel modes support this (i have one here) you basically hook one up to each line then designate one as a secondary link and set it up on the primarys web based setup page, this gets you high availability but not load balancing

as for cabeling, cat5 is the way to go, if you want gigabit and you have long runs then you may need cat 6 but most of the time cat5 is pasable (you can test it by laying it down before hand

so to sum up you need:
Cabel (cat5)
wall jacks for said cabel
a switch
a router
a modem (or two)

note that the switch, modem and router can be combined into the one item (like the linksys boxes), the plus with these is that they have basic filtering, if you need something better then you could replace the router with a linux boxes and one of the security distros, they are point and click these days (over a web interface) but its a good idea to have a firm understanding in networking and linux beforehand

anyway to answer the originol question about distributing the 2 broadband connections, once you have them sorted out about how they will talk to eachother and do what you want (HA or load balence) then thats it, you iwll only need the one jack to each room and the switch/router will take care of all the multiplexing of the data to the right line

btw, do you need 2 lines? if so of what type are they

i do have some stuff but its rough, and not yet anywhere near for release

as for the case, its always been a major problem with this project, i have a design that i am very very happy with but getting it built is another story

btw i joind the arm-linux lists and it appears that there are a couple of iMX.3 boards out theer i have never heard of, when i get a chance i will look into it
