Linux on Atom based devices

UPDATED some new infos:

https://xjesus.net/xjubuntu/xjubuntab-tablet-customizedcustomizable-distro-based-on-xubuntu-14-04-64-bits/

32 bits release is uploading.

Max, you should already be able to install it. I have tried on an USB drive and it gets installed. The problem is later I have to manually tell GRUB where to load it. In my case I have to type at the GRUB prompt:

linux (hd1,msdos5)/vmlinuz root=/dev/sdb5
initrd (hd1,msdos5)/initrd.img
boot


You can discover what you need to type following the guide in
https://github.com/Manouchehri/vi8/blob/master/Ubuntu_instructions.md


I hope @pinguy can solve this issue in PinguyBuilder or guide us to workaround it.

Pinguy I'm attaching the grub.cfg I got on my pendrive installed. I think it's missing the correct paths. In the installation I selected to install grub on the pendrive and everything went all right, but when I boot with that pendrive I get the grub command line like this picture:

Then if I manually the commands above I can boot. With hd0 if only the pendrive connected, or with hd1 if I connect one external hard disk where I booted the live installation...

Here is the grub.cfg

Thanks xjesus.

I see what you are saying, but I really don’t want a GRUB install/extra bootloader. What I want is a USB live drive that has persistance, or even better on an SD card in the slot. I have the same thing with Lighthouse 64 on my HP Tx1000, and Puppy Linux on my eeePc 701, both are on sd cards and when I want linux, I just select the sd card from the bios boot menu. No GRUB, no extra bootloader. If I install grub I would have to have a keyboard connected to the tab to select OS. Not ideal for a tablet!

I’ve installed Android with repartitioning using Intel Manufactoring Flash Tool.

After this, I tried to install “XJTab64-16.04.01-dist.iso” erasing all partitions, not EFI of course.

After reboot, I got this error:

How could I solve it? Teclast x98 Air 3G uses UEFI 32 Bit..

Hi Massimo, please try installing the 32 bits version: 16.04 32 bits

Or just copy the 32bits EFI file following instructions like https://github.com/Manouchehri/vi8/blob/master/Ubuntu_instructions.md

I think you better install it on the SD card or the USB pendrive. And you have the same result. You can go to the Teclast X98+ BIOS with power + Vol + and then select it in both cases.

Also you might have a look at this:

Auto-rotate is not working yet and once you launch it, then you can’t rotate the screen with the other buttons. I’m removing the auto-rotate button until I get it to work properly.

Massimo, did you try the 16.04 distro or the 14.04?? From what I’ve seen the 14.04 distro has a much less complicated boot script and way less features installed. Maybe try an older version of the 14.04 distro? Xjesus is the man!! All you need to do is pray for a working version and he delivers. His effort here has been super. Thanks again for your work xjesus. Did you see that glitch? on the downloads page where 1700+ people from china downloaded your distro in one day??!! Teclast…lol Max

Hi, I’ve tested some ISOs from:

• XJUbunTAB : Tablet Customized/Customizable distro based on Xubuntu 14.04 and 16.04 64 bits

I think I need to use Windisk32 instead of Rufus. Another thing, maybe I need to change my Bios, because my tab comes with a dual boot bios (yes, double OS is manage by Bios..)..Maybe I need to flash single boot Bios! Edit: Guys, with a dual boot tablet you need to boot into Windows partition, after this you can shutdown and boot from an Ubuntu bootable pendrive with no problem! <noscript></noscript>I’ve tested XJTab64-16.04.01-dist.iso, and I have inverted touchscreen: when I touch in the top left, mouse move in the bottom right side! MicroSD reader work properly. Display rotation doesn’t. Wifi doesn’t work. Mobile network (3G) doesn’t work too! I attach my lshw command output.

If someone wants to try the kernels in the ASUS google drive.

These kernels are working on other tablets like ASUS Transformer

Also 4.6rc2 is out here

Jesus Manuel I cannot download your 32 bit ISO..Download starts but after some minutes stops..

Edit: is it possible to upgrade Grub2 to 2.02 Beta2-29ubuntu 0.2?

x64 ISOs works but we just need the newest version of Grub2 to add UEFI 32 Bit patch!!

[Anonymous]

I am downloading it to try… But it looks Ok.

It has a newer Grub (2.02-beta2.36), but I just realized the 32 bits release Grub-EFI-ia32 wasn’t installed. I’ll upload tonight a corrected release with some other minor updates.

In the 64 bits release I’ve also changed the Grub-Efi from 64 to 32. Hopefully then everything works perfect on these tablets.

Oh wow man!

I’ve installed your Xubuntu, I don’t remember the release..

But I can say today I can boot into Xubuntu. I boot from the Live usb, during Grub booting I press “C” and write each of the following command:

#linux (hd1,gpt2)/vmlinuz root=/dev/mmcblk0p2
#initrd (hd1,gpt2)/initrd.img
#boot

We have Android Device Tree for Teclast x98 Air 3G tablets, could you merge drivers?

Edit: how to merge this fix?

Also google /sys/firmware/efi/fw_platform_size It may come in handy.

Congrats Massimo! We are getting it!

 

In the releases I’m uploading right now it’s installed the last PinguyBuilder and hopefully solves this hassle.

 

Merging drivers from Android… Hope someone here has the knowledge to do it, I don’t. As far as I know Lollipop uses kernel 3.16 and things might be quite different.

If you want to patch, it’s not that easy and I don’t know how to do it. Daniel some posts before explained a little how to do that.

Thanks a lot @pinguy!!! We’ll see if this helps.

One question: Why can’t I login to Unity in the live USB? I can logout from Xubuntu, select “Ubuntu” but it drives me to “Xubuntu” again…

(In my distro you need to enter user “usu” and blank password to try it by the way)

Another question: How can I select the default graphical interface? For example if I want to login in Ubuntu by default instead of Xubuntu in the live USB.

Xjesus, great to see you are tinkering a bit with the live usb. It would certainly allow more people to test out the disto without worrying about screwing up their os installs.

I was doing some more experiments yesterday. I made a bootable SD card but try as a may, I could not get the bios to see it. I also tried to boot it by holding shift and restarting windows but no go either. It seems common that these tablets won’t boot from an sd card. I also burned a live dvd but I could no way, no how, boot from that either. I could see the drive and use it perfectly after I booted from the usb live u drive.

I also tried to get it to shut down without a hard power off with the cdrom connected to see if that was the issue, but it still fails to shut down @#&*.
