今天变成顺时针旋转90度了。。。

昨天把bug截图贴错了，今日补贴下！:)

What hardware is this running on, and which X driver does it use? I'm assuming it's an xrandr detection bug on that specific setup, since I've never seen this before...

Ahh, the X log told me which driver (intel), but knowing the exact hardware might be interesting. Is this a convertible tablet/laptop, perhaps, that thinks it's in tablet mode for some reason?

This is a really strange laptop helps us to find lots of bugs, a so-called super laptop ^_^

jiaowen attaches the hardware information later :)

Hi Jiaowen,

Can you provide the hardware information that was mentioned by Ma Jun previously?

Hi Aron, the hardware information is as follows.
