Linx 7 Tablet

Link: http://www.linx-tablets.com/linx-7.html

Install Notes:
- Enter BIOS by holding Del-key on boot (e.g. for disabling Secure Boot, boot priority, etc.)
- Using Kernel 4.0 Mainline (x64): (config)

- eMMC should be partitioned as follow:

/dev/mmcblk0p1 (type: ef00, size: 100M~, fs: FAT32, mount: /boot/efi)
/dev/mmcblk0p2 (type: 8300, size: 100M~, fs: ext4, mount: /boot) <= Note: tried without, but doesn't boot for some reason
/dev/mmcblk0p3 (type: 8300, size: max, fs: everything you like, mount: /)

- EFI is 32-bit, so you need to install a custom UEFI-bootloader.
Grub2 i386-efi seems to be only one that works. Build a standalone version or download these files and place in /boot (untested).

Issues:
- Touchscreen isn't response and a bit laggy, it should be possible to tweak this.
Intel HD performance a bit weak.

Re: Linx 7 Tablet

Why would you post this to the forums? It would be so much better to put this on the wiki (or your blog).

Or am I missing the question?

Still missing the question(s).. <= See issue list

That's why I don't posted on the Wiki (yet).

Re: Linx 7 Tablet

Thank you for the info.

Maybe using i686 may help on bootlader and boot issues? (because of 32bit efi)

Did you try syslinux? The arch package should contain binaries for bios, efi32 and efi64.
Edit: The same goes for grub.

Found the problem! By forcing Grub to use a resolution/mode of 800x600x32 it now boots without any issues!
Don't ask why.. think because there are so many issues with EFI and only Windows get checked for booting (normally).

And no.. not going back to i686! x64 is the way to go!

Thanks for the tip!

For now I stick with Grub2-i686-efi, don't want to rebuild again.

Re: Linx 7 Tablet

You mentioned in another thread that you were trying some kernel patches to get the touchscreen working properly. Which patches were you looking at?

Didn't work, sorry.
