How to setup the xorg.conf.d of xfce4 in nexus7 device

[evel]

Hi Team,

I just try to install the archlinuxarm into my nexus7, now the basic system is build up, I can enter the desktop environment but seems only the touchpad not works correctlly.

the whole desktop showing in vertical direction.

like when I touch and move up the cursor, the drag will be always enable to select object of desktop,

when I touch and move 'up', the cursor will moved 'left'
when I touch and move 'down', the cursor will moved 'right'
when I touch and move 'left', the cursor will moved 'down'
when I touch and move 'left', the cursor will moved 'up'

Where I can setup correct this move method of the touch setting? How can I disable the drap feature?

also attached some of the logs as following:

Immediate suggestion is using rotation.

Thank you sir.

Just seems the screen has been locked to using rotate, but I am a new bird on this Xorg setting.
It would be great you can guide me how to setting up this monitor rotate parameter?

Thanks!

I am not being mean in giving you this link, the methods should be obvious.

thanks, but seems the device haven't install the correct drivers so still not reading on the Monitor setting successful.

using the xrandr of checking display device info

"cannot open display” error will found.
