I’ve just got a cheap refurbished Lenovo Helix 2 and XJubuntu works almost 100% with normal 4.4 kernel: WiFi, sound over speakers and HDMI, touchscreen, stylus, camera, etc. Only problem so far is suspending, but it can hibernate.

My advise would be to buy a second hand cheap Core-M instead of an Atom. In E-bay you can find very cheap Helix 2 and Dell Vostro’s. Or just buy a Cube i7/i9.

I’ve just ordered mine and I’ll create a special release of XJUbunTAB for this tablet with the last kernel available.

[xjesus]

I’ve released another “sta” version with fixes to the hardware acceleration in Firefox/Chrome. I’ve documented it in the post https://xjesus.net/xjubuntu/2016/07/10/xjubuntab-16-07-09-touchscreen-ready-with-gestures/

The “oibaf” version doesn’t boot in my X98+ but might work in some other tablets.

Once installed the “sta” version, I can add the “oibaf” PPA and get some improvements in graphics but nothing really important.

[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.

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?

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

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.

[xjesus]

Ups! Now the link is correct: http://pastebin.com/uEFdgj3h

The patch is https://github.com/hadess/rtl8723bs

I can install it with make , sudo make install , etc.

But then as the instructions say, you have to apply the patches in the “patches” folder. And that’s where I’m stuck. I do “patch -p1 < … ” with all the patches and always get errors like the pastebin one.

Hi Daniel, the last release (03.27 or 03.28) boots to the graphical interface on my Teclast X98 Plus A5C8, with booth 14.04 and 16.04. They don’t have the patches for the WiFi applied that hangs the tablet boot process.

03.21 and 03.23 were booting only with 14.04 because it didn’t include the patches.

When I say 14.04 I mean this folder:

https://sourceforge.net/projects/xjubuntu/files/Tablets%20Intel/

When I say 16.04 I mean this other folder:

https://sourceforge.net/projects/xjubuntu/files/16.04%2064%20bits%20-%20Very%20stable%20Beta/

 

The basic difference up until now is that the gcc-compiler was newer in 16.04 and was letting me install the WiFi patches but without other patches needed as well to avoid the hang of the boot process.

Right now I’ve included the last gcc-compiler in 14.04 too so I will be able to compile everything. But still I have problems with the “patch -p1 < …” commands, and that’s the issue I’ve asked on github.

@pinguy

Thanks! It’s solved now.

I’m still struggling to patch the WiFi. It’s getting me mad. I’m sure the problem is that I’m not applying the patch correctly. Can somebody help me?

I’ve opened a ticket issue here: https://github.com/hadess/rtl8723bs/issues/61

 

[xjesus]

Yes, the upload was incomplete. Now it should be all right. Thank you for warning me.

This morning I’m uploading a new release based on 4.6rc1 kernel so please wait and test this.

If someone could test this you would be doing me a huge favour. If it boots and works I will re-package my distro and re-release it with the patches. Pinguy_OS_14.04.4-3-LTS-Mini_Atom.iso

It doesn’t work on my Teclast X98Plus A5C8

This is where it gets stuck:

It works in Virtualbox though.

My last test on 16.04 with 4.4.4 kernel and the last pinguybuilder 4.3.6beta, removing patch for RT8723bs and vitualbox-guest-utils has resulted in a login screen (lightdm) where it only lets me choose the user “other…” and if I manually enter live or “usu” (my user on the Virtualbox I built the ISO) I can’t login. I’ve tried blank passwords as well.

My last test on 14.04 with 4.4.4 kernel is working but as I said I can’t install/compile patches, I suppose it’s expecting the new upgraded compiler.

I’m downloading your new Pinguy Mini Atom and will try it.

I tried some days ago 4.4.5 , 4.4.6 and 4.5 kernels and they didn’t work. But I might try again if I find the time.

[xjesus]

I think the problem is on the patches and/or virtualbox guest additions because the only kernels that can boot right (3.13 or 4.4.4 on Ubuntu 14.04) can’t compile the patches. And kernel 4.4.4 in Ubuntu 14.04 can’t install Virtualbox guest additions.

I mean, the only way I can boot the live graphical interface is with the combination that can’t compile the patches.

These are the error logs with kernel 4.4.4 in Ubuntu 14.04 trying to install the patches for touchscreen and Realtek 8723bs WiFi and Bluetooth:

http://pastebin.com/j40FECt1

In Ubuntu 16.04 and kernel 4.4.4 I can compile these same patches and install Virtualbox guest additions, but them it doesn’t boot!

@pinguy I’ve just tried your Pinguy OS mini Atom and this is where it gets stuck:

https://drive.google.com/file/d/0B4TUehAb_iPFSTJIdjE4THAwbVE/view?usp=sharing

With my 14.04 distro I can only boot to the graphical interface with kernel 3.13 or 4.4.4 (manually downloaded from ppa) but I can’t boot with the other LTS’s 3.16, 3.19 or 4.4.0.X

But now again I have problems with 4.4.4 to boot the live USB.

With the 16.04 distro I’ve got different random results but sometimes with 4.4.4 I was able to boot and sometimes with lts-xenial (4.4.0.X) too. But right now it doesn’t boot.

 

I also tried the daily Xenial Ubuntu and it boots all right.

 

In the 14.04 distro I am using graphic drivers from ppa:xorg-edgers/ppa

Well, most of the last tablets you can see around this web have 4GB already, even 8GB some of them. Also the fact that Chrome was dropping support for 32 bits made me think to go for 64 bits first. But when I’ll find the time I’ll make the 32 bits as well, which supports 4GB with PAE and consume less RAM indeed…
