After I installed the display driver, I rebooted the computer and the 3D effects (compositing) are no longer shown. Only 3D applications and 3D games use the display driver to display 3D objects. When I perform the following steps. KDE try to enable compositing, but one second later KDE disable compositing again: 1. Go to "Personal settings" -> Desktop -> Desktop Effects 2. Go to the tab "General" 3. enable composite -> "Resume Compositing" This issue only happens with compositing type "openGL". I assume the openGL detection makes trouble. When I selected an another compositing type like "XRender". It partially works, but it is not a satisfactory solution. I open the console and type some commands to get information about GLX: # fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3870 OpenGL version string: 3.2.9756 Compatibility Profile Context This command shows me a 3D cube with gears: # fgl_glxgears Using GLX_SGIX_pbuffer 1956 frames in 5.0 seconds = 391.200 FPS 2518 frames in 5.0 seconds = 503.600 FPS 2209 frames in 5.0 seconds = 441.800 FPS .. and this shows me a 3D cube with gears too: # glxgears *** NOTE: Don't use glxgears as a benchmark. OpenGL implementations are not optimized for frame rates >> 60fps, thus these numbers are meaningless when compared between vendors. 5011 frames in 5.0 seconds = 1001.724 FPS 6247 frames in 5.0 seconds = 1248.711 FPS 5882 frames in 5.0 seconds = 1176.378 FPS 6273 frames in 5.0 seconds = 1254.183 FPS 6447 frames in 5.0 seconds = 1289.266 FPS .. # fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3870 OpenGL version string: 3.2.9756 Compatibility Profile Context I upload 3 another important files about system information: - output of systemsettings -> "Personal settings" - system configuration report file from atigetsysteminfo.sh - output of glxinfo The only workaround that works: I go to the "Personal settings" -> Desktop -> Desktop Effects, then I go to the tab "Advanced" and checked the option "Disable functionally checks". - Who is to blame now? fglrx 8.723 or KDE 4.4.2 ? - Can we solve this issue in KDE 4.4.2 or this is a bug in fglrx driver again? Kind Regards, Sebastian (openSUSE Member) Reproducible: Always Steps to Reproduce: 1. Go to "Personal settings" -> Desktop -> Desktop Effects 2. Go to the tab "General" 3. Try to enable compositing -> "Resume Compositing" Actual Results: KDE try to enable compositing, but shortly disable it again. Expected Results: Kde enable compositing. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
