Linux on Atom based devices

Thank you Daniel. I’m not experienced with patches but hope your indications will help me solve this.

In 14.04 03.27 I didn’t include the last gcc compiler so if you want to play with it you will have to

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update

sudo apt-get install g++-5


In the next releases will be included.

Or you can play with 16.04.

It's easier to work on a Virtualbox and then you can create your own ISO.

As soon as I type those commands to install the WiFi drivers, the tablet freezes in few seconds. Or if I try to boot any ISO with the drivers installed (but not the patches) it doesn’t get to boot. I’ve got it to boot with WiFi only once that I thought that I got it but then it never worked anymore . It may be related to this:

or other similar issues

Hi guys, how could I test it?

I cannot boot in Live..

[Anonymous]

Hi guys,

I saw an old topic about Ubuntu 14.04 x64 on Teclast tablet. You can find the topic (guide) at the following link:

• Ubuntu 14.04 x64 on Teclast x98 Air tablet

It is in chinese, if you are not registred you cannot see all stuff. So I decided to print PDF of the page, one in original language and one in english.

I decided to attach also the grub2 boot file mentioned as second step in the guide.

So, I just tested the latest 16.04 rc1 build. Things are definitely improving. The screen rotation shortcuts work, my D-link usb wifi works. I was able to log out and back in with the “usu” user and blank password, and switch the keyboard. The issue I was having with the M key seems to be caused by my little portable keyboard, when I switched keyboards the M was M not zero. I tried to play a YouTube video to test the sound but then I had a lockup. I did a hard power-down and the USB drive will not boot now (same as with previous versions)   All this is with the LIVE boot option.

I will fool around with trying to get a persistent live USB working in the next few days.

Great progress guys!!

Hi,

please could you help me to understand how could I test it?

I have a Teclast x98 Air 3G 64Gb dual boot Win10 + Android, I made a pendrive with Rufus and every ISOs I fund in this topic, using the “bootia32.efi”, It boots but after some time I get this error:

Can you help me?

[Anonymous]

I make the usb with rufus and select to iso, bios and efi option, bootable,untick add icons option, it throws 2 dialoge boxes bitching about downloading new drivers….etc, I click no twice and create the usb boot drive.

I have a X98 Plus which is Cherry Trail, xjesus is also using the same tab for his development.

Could be he has things set up for 64bit bios, which we have. I seem to remember the older 3G (baytrail) is only 32bit bios? Maybe with a few tweeks you could get it to boot, IDK.

Yep you are right, old Teclast Air 3G Baytrail use a 32 Bit UEFI. I cannot understand the issue, maybe I need to erase all EFI files?

I mean, in the pendrive (EFI\BOOT) generated with Rufus you can find:

• bootia32.efi
• bootx64.efi
• grubx64.efi

Maybe I just need to erase the 64 bit EFI files?

[xjesus]

Please try to do that and let us know if there is any difference.

I’m going to publish a 32bit release as well and hopefully it will work with your tablet.

Cannot boot 🙁

The same error..

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

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!

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.

Guys,

I’ve tested also a traditional Ubuntu 16.04 beta ISO..Touchscreen is inverted/reversed by default, but online we can find some guide about it:

• Touchscreen – Ubuntu WiKi

MicroSD work fine, so it is native supported by Linux Kernel.

Power Management recognize battery mode. WiFi doesn’t work. Network 3G Mobile connection doesn’t work. Front and near camera doesn’t work.

Edit: attached “dmesg_teclast_x98_air_3g.txt“.

In this way you can see more info about booting..

[Anonymous]

Hmmm, new build!! Downloading!

My first attempt at a Live persistent install with  unetbootin was unsuccessful, sort of. It booted fine and I created a test folder, then tried to soft shutdown with the keep files option ticked. The drive was flashing but then the same endless spinning circle as before. Maybe I didn’t wait long enough I seem to remember that it can take a while. I hard powered down and tried a reboot. This time it went right through to the shell initialization but threw a virtual box error and hung. It is progress though, as any previous attempt froze at the spinning boot-up circle. I am going to try again and leave the keep files unticked, as I already should have persistence.

Update: Well that didn’t work either 🙁 It seems that when it tries to shutdown everything goes ok until…..FAILED unmount cdrom.mount.

I think that when it boots it says it can’t mount cdrom (no cdrom..lol) and it makes sense that it would fail when it tries to unmount it.

I may try a CD-RW in my USB cdrom drive and boot it from that to see if it will shutdown then! Persistence may pay off, pardon the pun 🙂
