<pre>Monitors are correctly reported in xrandr, however when both VGA (ASUS VW193)
and internal laptop monitor (ASUS K55DR) are connected, image is only shown on
one screen at the time. When HDMI output is connected (another monitor or tv)
image is displayed seemingly random (either both HDMI and VGA output image, or
only VGA, or internal monitor and HDMI - but never all three or VGA and
internal monitor at the same time). Also at 1080i screen glitches (as seen on
ubuntu bug report).
Hardware is functional under Windows or fglrx drivers
Original issue was reported @ launchpad.net here
<a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1553441">https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1553441</a>
That bug report contains log files from xOrg, and images that could better
explain bug that is affecting me (as I'm not native speaker, if that isn't
obvious enough :)). If necessary I can provide more logs from latest mainline
kernel.
Last kernel version which I tested (and reproduced bug) was mainline Ubuntu
4.10.0-041000rc7-lowlatency</pre>
