I have a laptop running Xubuntu 12.10, with an Ati 7970M and a second monitor in a vertical orientation. I cannot seem to orient it to be two adjacent displays without it glitching. If I rotate the other display, it's fine, but the two are massively overlayed. Using both xrandr and arandr I tried shifting the 2nd display shifted to the right of my monitor and that causes it to glitch, until I rotate it back to normal. I can rotate my primary display without it glitching. It's only when the 2nd display is rotated and not sharing space with display1 that it's not buggy, but that's pretty useless. I've tried both the catalyst 12.1 drivers as well as the 12.2 beta with no luck.
Anyone have any ideas for how to handle this?
