[WIP] Ubuntu on G9 v0.2
- Thread starter a1Pha
- Start date
One way to return is to flash official rom. After that remove ubuntus img, and insert new img. then just boot to recovery, choose sde, and remove android kernel and flash new kernel.
Some later edits:
EDIT1:
It is hard, (atleast for me) to write without onscreen keyboard, because the rear usb port doesn't work, and i have lost my otg cable. Is there any tricks how can i input this? I have ordered new
cable, and it will arrive in 3 weeks. Kinda long time
.EDIT2:
I was reading the general android hacking and found this: [HOWTO] Seamless integration of Android and GNU/Linux Debian. It would be awesome if that would work for G9.

How to kill X server
I would like to kill the X server and work from a console
terminal, Ctrl-Alt-Delete does not work, nor does switching
between ttys with Alt-f1, Alt-f2 , Ctrl-Alt-f2, etc.
How can I do this?
Also, is there an Android image that will dual boot from
the same kernel?

I think rooted 4.0.4 test ICS will boot with this kernel. You can get new kernel from few pages back, but the touchscreen doesn't work in it for all tablets. You need the x-server for on-screen keyboard. I don't know how to kill it.

Traditionally it was CTRL-ALT-Backspace... if not disabled (cannot try at the moment).
If memory is not critical for your work, just abandon the X and connect over ssh from another machine. The ssh server is included into this build and works perfectly.
Then look into initialization files - where the graphical mode is turned on.
Recently I tried plasma active build for archos g9 on my 101 g9 16gb turbo.
I have made .ext4 image form sd card build of active plasma, with some minimal modifications, and successfully boot it from multi boot menu - kernel image and init posted in this thread (ubu1204_021). That was expected since both builds run on 3.0.8.(+) kernel.
Touchscreen works as usual.
So, I concluded that ubuntu touchscreen problem is not in drivers (kernel modules) since same modules work with plasma active, but more probably in some X configuration files or udev (maybe it doesnt recognize our touchscreen), or udev rules form ubuntu.
Also, I noticed one significant difference between ubuntu and plasma active X - active build X uses mtev (xorg-x11-drv-mtev) as multitouch driver (xorg driver, not kernel module), and ubuntu uses evdev driver.
But, there is no mtev package for ubuntu, so I ve tried to compile it form source.I didnt succeed (I don know why, probably some dependencies).
I am certain that mtev driver is the key for getting our A101S touchscreen to work.

CTRL-ALT-Backspace does not work.
I tried modifying lightdm.conf to stop the display manager on run level 2, but that had no
effect.
Where else might I look?
I use an external keyboard and mouse throught the G3 USB port.
What I look forward to is runing GNU Emacs in console most of the time, and
starting X with FVWM from the command line as needed.
Ubuntu really was not necessary, but the only game in town with a proper external
keyboard.
Did you try "setxkbmap -option terminate:ctrl_alt_bksp" before pressing CTRL-ALT-BACKSPACE" ?

That let me kill the X server, but the X server simply re-started.
Where are the startup settings that control starting the X server?
Also, what is the device name for the GPS unit? Do I need to modprobe
a driver for it?

IIRC you should get full screen console with Ctrl+Alt+F[1-5] (but tty1 may be in use by xserver).
As for autostart- try disabling display manager as it is responsible for keeping xserver and window manager sessions alive
The f keys don't switch between terminals.
I tried all options at the link suggested except for uninstalling lightgdm, which would not be easy to undo by mounting the
image and editing files.
Two that probably stopped the desktop manager in the login sequence also left me stuck at the multiboot screen. Maybe t
here is something in a script that waits for the desktop manager before handing off?
I can't boot right now, so I can't easily test if simply killing the X server is enough to get the console after modifying
the tty1.conf and lightgdm.conf files to do the right things in run level 2.
EDIT:
Nothing works.
Changing the config files and killing the X server, restarts the X server.
sudo stop lightdm
leads to a freeze. So does uninstalling lightdm and killing the X server.
This machine in a console with frame buffer for the occasional graphic,
or with X and FVWM would be fantastic.

Wanted to make my contribution, I'll uplad a version running LXDE Desktop enviroment, plus some optimizations I've done to it to make it faster... Still trying to get the sgx drivers to work... but they will, sooner or later
Did you get touchscreen working? It wasnt working in 0.21

Can you post a link to how you are building these? What architecture target do you set
when setting up your crosscompiler, and how do you set up the init sequence, X config, kernel config, etc?
It's in the first post. First you doynload the ubuntu compressed archive which you uncompress. Then you use android development bridge to move the uncrompressed file to your tablet. After that you just install the kernel and reboot.

hi there!
i have an archos with 250gb and i tried this:
ln -s /mnt/storage/ubu1204.img.ext4 /data/media/.
and did not worked when i rebooted.
i'm going to make the same now to test it.

Next location to try is /data/local.

USB working, i use my USB keyboard and wireless mouse, but my other mice did not work.
I used a USB hub. (worked on my em28xx TV card too, but was not good because v4l2 problems.)3hey guys,
i know i ask lot of SED and so on, but i want to know if there's some full ! thread how to root my archos, how to enable SED and then how to dualboot ... i know that there is allways a thread how to root/enable SED, but it's really old and i don't know if there are some new ones (.. i'm sorry but im really "vorsichtig") ... i have seen some full thread, but the links to download the files are from megaupload (megaupload , you know what the problem is - for those who not so good informed, megaupload was closed ;-( ) .. and so it would relly really nice if someone can post me a full thread or all links i need (actual links pls) ... a big thanks - tom

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
