This is a place to coordinate developers working on dekko2. (It is not the place to discuss individual bugs)

In the good old days we had dekko and it mostly worked ok. At some point a rewrite as dekko2 was deemed necessary. The rewrite was started but not completely finished. In addition the platform has moved on beneath dekko (xenial). Time has gone by and development rate of dekko has dropped.

As of today, there is no working dekko for xenial UT.

Over the last couple weeks I see here and there on various UT telegram channels messages pop up about various people trying to work on dekko. Some wrestling with the build system. Somewhere a test build showed up. Some critical bugs were mentioned (settings, system load). Workarounds and some fixes too. I think it's time to coordinate efforts. So we don't independently solve the same problems multiple times, but instead move forward faster.

So all you dekko2 hackers, speak up below with whatever you do / did on dekko2. What you need help with.

Let's make it happen!

PS: This is not an attempt to hijack the project from the current maintainer @DanChapman . Personally, I think the best future for email on UT would be a Dan maintained dekko2 with a small community of developers cooperating. Dan seems to be on a hiatus right now. Let's see what the future brings.

PPS: If you are not actively developing on dekko, then help us stay focussed by not going off topic here! Maybe you really want to encourage people to work on dekko. Or maybe you are very frustrated because you really need an email client. Well, yes, we know. We all are. Feel free to up (or down) vote posts. Or maybe you want to report an issue or suggest a feature. Then use the bug tracker. Or you just have a question. Then start a new thread or go here https://forums.ubports.com/topic/1750/dekko-0-1-6-beta2-released/1

I almost don't dare to ask, but .... Qt update?

It is our pleasure to announce the release of Dekko2 for Xenial

You find it in the open-store on your device and at https://open-store.io/dekko2.dekkan

Yes there are still bugs. We know, but it should definitely be good enough to allow you to read and write your emails from UT.

Try it out and feel free to praise or curse us below. Let us know what you think.

Pick one (any) convergent user story and make it a perfect experience out of the box.

For example: I receive an email from a coworker asking me to work on some spreadsheet. Dock phone and work desktop style, listening to music on my headphones. Realise I miss some info. Text another person with a question. Receive a phone call interupting me. Take the phone out of the dock and talk while I walk to the coffee shop. End the call and finish the spreadsheet on the phone/tablet interface in the coffee shop. Email the file back.

All those features are kinda there, but there are a bunch of usability features that kill this (and similar) workflows. I would suggest you draft a story like this, then test it and prioritise any bugs you run into. Docking ain't reliable - fix this. Email app closes and interrupts my drafting when switching to browser /spreadsheet - fix that. Out of the box UI scaling for localc doesn't allow me to work efficiently on a tablet display - fix it.

No need to make everything perfect, but pick one story and maybe one device and make that one really shine. If it ain't the "mobile office work" above it could be the visual artist - now you need to make sure that krita works perfectly on the tablet - does taht require better touch input in xmir well then this is your top prio feature. Or maybe its wayland on mir. The user is not gonna care as long as the workflow is awesome.

Pick a story that is achievable, but sets ubports apart from ios/android. Getting krita to run is too hard - what about preparing, adjusting and giving a presentation from the phone including live pdf annotation xournal style.

Make sure to produce a release video that shows off! Focus on the added value for the user instead of the technical feature of how you adjusted the dpi for Xmir or whatever.

I'm trying to get Halium running on the Nexus 7 2013 gsm variant "deb".

I've made a few steps already. Most notably: Plasma Mobile starts!

I'm keeping (and updating while I progress) the summary below, so that:

I don't forget what steps I took
Others can help to improve this
Others can use this as inspiration for their ports

test and debug

Follow steps here http://docs.halium.org/en/latest/porting/debug-build/
if you want to force init into telnet, add kernel parameter bootmode=debug:

fastboot -c "$(abootimg -i hybris-boot.img | sed -ne '/cmdline/s/. cmdline . //p' ) bootmode=debug" boot hybris-boot.img

Android image

cd halium
mka systemimage
ls -l out/target/product/deb/system.img

Rootfs

Halium rootfs

get it

https://docs.halium.org/en/latest/porting/install-build/reference-rootfs.html

install it

to install the rootfs you need working adb. I use this twrp recovery: https://eu.dl.twrp.me/deb/twrp-3.0.2-0-deb.img.html (had some problems with 3.1.1-0)
boot into twrp recovery

git clone https://github.com/Halium/halium-scripts
./halium-scripts/halium-install halium-rootfs-20170630-151006.tar.gz halium/out/target/product/deb/system.img

The device should reboot and get to the point where it announces usb networking:

lsusb -vd 0fce: | grep -i serial
  iSerial                 3 GNU/Linux Device on usb0 10.15.19.82

reboot into twrp recovery to set the root password

adb shell
cd /data
mkdir mnt
mount rootfs.img mnt/
chroot mnt /bin/bash 
export PATH=/sbin:/bin:/usr/sbin:/usr/bin:$PATH
passwd

connect to it

reboot the device and wait for usb networking to come up as above
configure usb network on your desktop in a similar way as above for telnet, but now for ssh

sudo ip address add 10.15.19.1 dev enp0s20f0u7 
sudo ip route add 10.15.19.82 dev enp0s20f0u7

login via ssh

ssh root@10.15.19.82

fix path variable

echo $PATH
/usr/bin:/bin
export PATH=/usr/sbin:/sbin:$PATH
echo 'export PATH=/usr/sbin:/sbin:$PATH' >> /root/.bashrc

what works

UBports rootfs

Tried the rootfs from here: http://cdimage.ubports.com/rootfs/ but it doesn't do too much for me:

screen stays on the Google logo
no usb iSerial messages
no usb network interface seems to come up
last_kmsg shows that systemd does take over http://paste.ubuntu.com/25419054/ however,
it complains that "systemd[1]: Failed to start LXC Android Config and Container Initialization."
no adb interface comes up, even though in TWRP/chroot I see that android-tools-adbd.service is enabled

Plasma mobile rootfs

git clone https://github.com/bhush9/rootfs-builder bhush9-rootfs-builder
cd bhush9-rootfs-builder
# follow the instructions in README to patch lb_chroot_live-packages
sudo ./build.sh
# waaaaait
# install it

The reboot takes about a minute. Then you'll hear an audible greeting and afterwards you are greeted by the plasma mobile login screen. You can login and play around a bit. Not much to do though. No network connection and it's not possible to ssh in.

Reboot back into TWRP and chroot.

To be able to use the ssh server, you need to generate ssh server keys: dpkg-reconfigure openssh-server
Preferably enable password less login :

adb shell mkdir /home/phablet/.ssh
adb push ~/.ssh/id.pub /home/phablet/.ssh/authorized_keys
// todo : some chmod/chown needed?

reboot, setup usbnet and then reboot and login as ssh phablet@10.15.19.82
Alternatively, you can set the passwords, but I don't do this because it seems to actually break the graphical login:

passwd 
passwd: Authentication token manipulation error
passwd: password unchanged
# fix passwd
apt remove libnss-extrausers
pam-auth-update 
# select everything but extrausers
passwd # set root password 
passwd phablet # set user password

Haven't tried yet. I'm not very familiar with arch.

What's next?

Get ubports to run
Get PM to run on halium-boot
Check out LuneOS
Check out SailfishOS
Build a .zip file, only makes sense if some OS is remotely usable, PM is close but still not there
get lxc-attach to work
patch out the noise dmesg logging of the battery

Any tips or feedback appreciated!

doniks

Oh and of course, the elephant in the room: How's 16.04 coming along?

doniks

Tell me. How awesome is it to work on one "real" recent Linux kernel for the Pine Phone instead of a dozen incompatible and weird and ancient Android hacks?

doniks

How big is your head- and heartache after seeing the responses to your thread: Want To Develop UT And Need A Device?

doniks

Enjoy your real lives guys. Well deserved. And thanks for the continuous updates!

doniks

@3arn0wl said in PinePhone:

is it right to assume that the PinePhone, being a Linux phone, won't need Libertine to run Xorg apps?

No. It is "more" of a Linux phone than others that run some (old, forked) version of the Linux kernel in the sense that it runs a recent upstream version of the Linux kernel.

Everything that happens on top of the kernel is up to the distro you run. In the case of Ubuntu Touch, it will be Mir and Libertine. If you run Plasma, Lune, Postmarket, something else it will be whatever that distro provides

doniks

Only some standards.
Like described: If i install apache2, it will not start, because of some restrictions inside libertine - at this moment i cant remember.

Well, it's in the eye of the beholder what is standard ... I personally have no experience with apache, so I wouldn't have a clue what is standard .... well let me just try ... sudo apt install apache2 on my laptop and afterward go to http://localhost shows some default website. ha! that was easy. I somehow feared it was more difficult:) Ok, try again on my deb: libertine-container-manager install-package -p apache2 ... no, it doesn't like that

Setting up apache2 (2.4.18-2ubuntu3.17) ...
/bin/sh: 1: .: Can't open /etc/apache2/envvars
Could not read /etc/apache2/envvars
dpkg: error processing package apache2 (--configure):
 subprocess installed post-installation script returned error exit status 2

https://paste.ubuntu.com/p/MBKhfGTDjT/

Mhm. I guess you'd have to dig into whatever happens in "Setting up". I poked a little bit but .deb packages are still pretty much magic black boxes to me. I don't know where to find the setup code...

@bforpc said in runnig a webserver - no chance:

Dear Group,

I have tried the last 3 days without success. Apache is not running under libertine, nginx are running, but - no matter what the error is - it does not found any file in the web root directory.

Only hint - no error - i found in debug logs of nginx are:
2020/10/05 15:47:21 [debug] 9911#9911: *1 http script var: "/"
2020/10/05 15:47:21 [debug] 9911#9911: *1 trying to use dir: "/" "/var/www/html/"

2020/10/05 15:47:21 [debug] 9911#9911: *1 http special response: 404, "/?"
I have tried also running the Web Servers from the root of the nexus 5 it self. This will be working - but breaks the system and then some apps (all web browsers) are not working annymore. morph browser crashes the hole system into a reboot.

Is there a chance, to have ubport up and running and also a web server inkl. php?

Bfo

Let me try to eschew the philosophical conversation and have a technical one (and ducking my head while doing so;) ).

Can you give more detail about what exactly you tried and what exactly was the result. I understand you installed apache in libertine?! which packages precisely, how did you configure it, start it, test it ...

doniks

I don't really understand. Do you mean "flip" as in, now I can only read the text when looking at the screen in a mirror? I don't think there is any such feature. If this is actually what you are asking for, I can't help but ask you for more details about your special reason. I'm too curious!

I also don't know what dairy means or what xrandr -x does ...

If you talk about rotation, like turning it sideways right or left into landscape, or upside down, then yes, Ubuntu Touch generally supports this. There are a few stubborn parts that will not rotate at all, or not all 4 directions, like the lock screen and some apps.

@t3kg33k said in Nexus 7 2013 (16GB) install:

Update: That clued me in. So, this time I ran the UBports Installer AppImage as sudo and it looks to have been successful this time.
Thanks for the assist.

Ha. Interesting. I did not expect that. And actually, I do not understand it, but hey. Glad it worked!

doniks

@t3kg33k can you manually push the same file to the same location

can you adb push /some/file /cache/recovery using some file you have around? the device should be in recovery mode

doniks

@t3kg33k link?

@impreza233 said in ZRAM and Swap?:

@doniks myself and a fellow (@bartbart2003 ) have tested that on config, but it seems not working at this moment

mhm. so you did enable in the kernel config and it has rebuilt and booted successfully? Anything visible in kernel log?

I have never used zram before, but from quick research it looks as if it is all about creating a swap space (in compressed ram). Do you have a swap device now? Is it used (swapon -s)?

doniks

@impreza233 Looking forward to hear how this goes!

doniks

@impreza233 probably first kernel config https://github.com/ubports/kernel_vegetahd/blob/master/mediatek/config/krillin/autoconfig/kconfig/project#L1947 then check kernel log to see whether ut picks this up right away
