Description Kirill Müller 2014-03-17 14:49:07 UTC 
When I use intel-virtual-output with rotated display, calling xrandr without parameters shows the following:

xrandr: output VIRTUAL5 cannot use rotation "left" reflection "none"

Here's the output of `DISPLAY=:8 xrandr` with rotation enabled (tri-head, DP-2 is rotated):

Sorry, forgot to `git pull`. The issue persists with "ecc20fb intel-virtual-output: Discard unwanted events from the mouse recorder", and also with "dc66e66 sna: Improve guard against loading palettes whilst headless". Posting updated output of DISPLAY=:8 xrandr

Comment 3 Chris Wilson 2014-03-18 15:12:18 UTC 
Ok, this looks to be current then. Do you mind recompiling the ddx with ./configure --enable-debug=full and attaching the Xorg.0.log after setting up the remote displays and triggering the xrandr error?

Oops, should have actually read the output first. This is an old ddx, the current xf86-video-intel.git will read minimum 8x8, maximum 32767x32767.

Created attachment 96011 [details]
Xorg.0.log

I have just reinstalled from master, but to me it looks like the packaged version takes precedence -- rather unintuitive, I'd guess.?

Anyway, attaching Xorg.0.log.

Yeah, it's an oddity. ./configure by defaults installs into /usr/local/, but X doesn't look in /usr/local/ first. If you use ./configure --prefix=/usr $foo it will overwrite the /usr/lib/xorg/modules/intel_drv.so. Then the next time you install the Ubuntu package it will restore it back to system defaults. (Or apt-get reinstall xserver-xorg-video-intel)
Comment 7 Kirill Müller 2014-03-24 09:02:31 UTC 
Does not occur when using Git tip of xserver-xorg-video-intel installed by `./configure --prefix=/usr`.

Good to know, as this bug had me worried!
