[Asus UX360UA] Physical screen rotation not handled properly

[tjiagoM]

I've just installed Ubuntu 16.04.1 in dualboot on top of an Asus UX360UA, alongside with Windows 10. I've already installed the updates meanwhile.

This laptop has a 360º degree rotating screen. When I physically rotate my screen, Windows (or some installed driver, I don't know) detects that. Consequently, the image being displayed in the screen is rotated 180º and the keyboard is blocked. However, Ubuntu doesn't do nothing when I rotate the screen.

I think this is a bug because a fresh Ubuntu installation should recognise these laptop features. I searched a little bit and it seems there are some workarounds on this, but I guess Ubuntu installation should recognise this automatically?

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

So, it seems that in the upstream kernel the physical rotation is detected. I say this because when I rotate the 360º the keyboard is blocked (I try to write and I can't).

However, the screen is not rotated automatically nor any clue that something happened is shown in the screen, as we would expect.

So, I guess, the bug still exists in the upstream kernel, but with some differences.

[tjiagoM (tjiagom)]

An update on this issue now that I have kernel 4.14:

After executing `uname -a`, I have the following output:
`Linux tjiagom-UX360UA 4.14.0-041400-generic #201711122031 SMP Sun Nov 12 20:32:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux`

If I rotate the screen the keyboard is blocked, but the touchpad is still working when it shouldn't. Also, the screen is still not being rotated.

[Kai-Heng Feng (kaihengfeng)]

I think Unity doesn't support screen rotate. Please try latest Ubuntu or Ubuntu-Gnome.

[tjiagoM (tjiagom)]

@Kai-Heng, when the screen is rotated, the keyboard is locked, so that is detected somehow. Also, if you go to the screen display properties, you can rotate whether it is Unity or Gnome or others.
Thus, I guess it should be possible to combine this in some way.

[tjiagoM (tjiagom)]

An update: I now have kernel 4.16rc1 and the situation is exactly the same.
