Might also be worth mentioning I'm running KDE-4.11.3. Two monitors attached to the following card: akira ~ # lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] As per the summary... all worked fine with 3.8.13... I do recall having problems with 3.9.x but for unrelated reasons stuck with 3.8.x. Upgrade to 3.11.7 appears just fine apart from this problem.
Which version of x11-drivers/xf86-video-ati is that?
Summary updated with version number.
There's not really anything Gentoo developers can do to solve this. Please file a bug upstream https://bugs.freedesktop.org/enter_bug.cgi?product=DRI if the problem persists.
