[WIP] Ubuntu on G9 v0.2

a1Pha · Dec 14, 2011

Hey guys,
let's try to get Ubuntu working on our tablets.
adbd is included in the images, so you have a root shell over adb

SDE required.
Extract all.
adb push ubu1204.img.ext4 /data/media/
Reboot - SDE - Flash kernel and initrd
Multiboot menu 0.3 - ubu1204.img.ext4 (from the menu to start the ICS, such as "archos.ext4")
Done.
(passwords: ubuntu - ubuntu root - root)

Working:
- Booting on 80G9 and 101G9
- Touchscreen (touchpad mode)
- Keyboard via OTG cable
- Mass storage on rear USB-prt
- SD card automount on plugin
- LCD backlight brightness control via command line, lol
- Networking (incl. WiFi)

Changelog:
0.2:
- Made by szanalmas
- Upgrade to 12.04
- Kernel 3.0.8+
- Working WiFi (try adding a dummy network, then it works), Sound
- Switched from Unity to Gnome Classic

0.1:
- Initial build.

Todo:
- Bluetooth
- Hardware acceleration

a1Pha · Dec 14, 2011

Could you post some screenshots of ubuntu on g9?

twinnaz · Dec 15, 2011

For sure - just contact me when your tablet has arrived

Okay, I have edited the first post and added some links to screenshots.

Sorry, I don't understand your question :S

twinnaz · Dec 15, 2011

how would i implement a dualboot

a1Pha · Dec 15, 2011

You can take the initramfs.cpio.gz posted by letama in another thread (look at the link to Ice Cream Sandwich - the file is inside the archive you download).
Then extract it and have look at the scripts, which are provided there.
Basically you have to get the system to ask you, from which filesystem image you want to boot

TjaXanK · Dec 16, 2011

yep! you need to install SDE, restart your device, go in the developer menu and flash the initramfs.cpio.gz that letama posted in the ICS post, atleast that's how it was in the Gen8... by the looks of it the SDE menu is the same. Hope I helped

cajl · Dec 16, 2011

i wait the multi OS install
2.3
4.0
Ubuntu

trevd · Dec 16, 2011

Nice, I'll give this a go now.

Edit:

Works on the 101G9.
Keyboard Functions through OTG/Host Cable.
USB Mass Storage (Pen Drive) Functions on 3G Stick Port

Not tried anything else yet.

Are you using a lot of the same kernel objects which android is using?

Excellent Work.

twinnaz · Dec 16, 2011

alright thanks

Thank you very much, and also thanks for testing

I am using initramfs + kernel + modules provided by letama for his ICS-build.

By the way - I will upload a new build this night.
I have managed to get basic network functionality via adb + usbcable, so I have upgraded all packages and installed a touchscreen keyboard.
In the new build the LCD backlight brightness is now set to max on boot.
I also have added a user with sudo-permissions, so now settings are saved on reboot (not like in 0.1 where guest sessions were created).
Oh, and I will change the filesystem type from ext3 to ext4.

Still no real progress on WiFi or sound

P.S.: New build will support choosing between booting ICS and Ubuntu

//edit: sry guys, got some problems with my internet provider. i get reconnects every 30 seconds. i hope they get it fixed till tomorrow... sorry for delay, i'm going to upload the stuff tomorrow..

Might be worth giving it a go with a version 3 kernel, you may get some free driver support. although I could be talking nonsense

I activated the root login with my own password from adb and the touchscreen keyboard worked straight away on the 101. It must come with the the drivers preinstalled. I think letma's' done some work into the difference between the 80 and 101.

I've been playing with this all night. I think the drivers have been integrated in the main linux kernel so you should be able to build your own.
They could some prebuilt binaries out there as the OMAP4 board seems quite a popular board.
Also you might have some joy with this http://dev.omapzoom.org/pub/scm/integration/

It's all Good!

Archos 101 G9, HTC Sensation, HTC Hero

Hi Guys,

A1Pha, sorry, didn't have time to test your build, too much stuff going on...

Here is a quick feedback on wifi that may help you:

In android, here is how it works (from memory, don't have my laptop to check)

1) you need to create a nvs file corresponding to tablet, check android init.rc for the way it's done there...
2) Then when you do need wifi, insmod the tiwlan.ko
3) Then, load firmware (check wlan_loader in android init.rc, you should be able to reuse the command) and nvs. If all goes well up to here, you should be able to do ifconfig tiwlan0 and it should have a mac address.
4) Then start wpa_supplicant. You need the appropriate version of wpa_supplicant, 0.8 I think in android source code. You may want to build source code from android source with the appropriate options to remove android extensions.

Again, this is from memory, I'll try to give you more details tomorrow.

Regarding audio, this is mostly alsa so it shouldn't be impossible, you should be able to re-use the configuration found in archos rootfs in /usr/ sub directories. You have to insmod the proper modules though.

Best,

LeTama

Suggestion for the sound, try running the alsamixer and playing with that... worked in debian...

ahh. Thanks for that letama , You're a fountain of knowledge.

I'll give it a try during the holidays.

I was playing about with wpa_supplicant and android kernel drivers. I didn't have the right magic

) and my kernel knowledge is still in it's early stages (only been on the linux desktop for 1 year).
