I do have this issue too (Kubuntu 12.04). I have a Pentium Dual E2180 (quite old, I know) with an added ATI Radeon HD 3450 (installed fglrx "8.970-0ubuntu1", download from www.amd.com) to support two monitors (both 1920x1080). When I do absolutely nothing (only have Google Chrome running), X consumes about 10% CPU Time. When I move a window, this goes up to about 30%. Is there any information I can provide which could help identify the issue?
