Comment 20 for bug 192413

Marco: Yes (See also duplicate bug 166174). My setup is Kubuntu 8.10 with Kde 4.2 beta2 from the launchpad repos (4.1.85-0ubuntu1~intrepid1~ppa1), proprietary amd fglrx driver (8.561) and dual head setup. Under KDE4 the second screen stays blank. Amdcccle (amd graphical config tool) can identify second screen (displays identification number on second screen) and I can move the cursor over but it will have a different shape (X) on the second screen. On first screen panel is not visible (maybe because screen size is taken from 2nd display which has 1600x1200 instead of 1st displays 1400x1050??). Good old Windowmaker works perfectly fine with an otherwise unchanged setup. Under Kubuntu 8.04 with KDE 3.5.10 and same fglrx version dual head setup also works (although 3.5.10 has introduced another dual head Bug 170465).
