Greetings everybody! For about two weeks I'm now a happy owner of an intel-powered laptop (chipset, wifi, gfx) and wanted to give it a full test-drive of compiz and other GL-intensive programs. The laptop runs Xorg 7.1.1 and the i810 driver that comes with it (stock rpm from FC6). I'm forced to start compiz 0.3.4 with these options... --use-cow --strict-binding --indirect-rendering ... to merely get compiz to work. I cannot leave out any of those options, otherwise I don't see anything rendered by compiz. While I'm a bit spoiled regarding performance coming from my desktop-system (nvidia-driven, using nvidia's AIGLX), I did not expect the i915 (AIGLX) solution to be such a bad performer. At a resolution of 1280x800 I can barely use the cube-rotatation, switcher or drag-rotate while moving windows to different workspaces. Furthermore GL-apps leave artifacts on the screen when dragged around (even if ran under metacity) and I don't seem to be able to get transparent GL-apps working (e.g. try gl-cairo-cube from people.freedesktop.org/~macslow). I know that the i915 is an integrated graphics-chip solution using only system-memory, but I remember people showcasing screencaptures of such systems with much better performance under compiz. Is all this only a Xorg/driver problem or will I never get any decent performance (and feature-parity compared to low-end nvidia-hardware) from this laptop when running a composited desktop-environemnt? Also the screensaver seems to be to much for this setup as it only display a black nothing (only the mouse-cursor is visible and I have a hard time entering my password to unlock it again). What disappoints me also is the lack of support for transparent GL-apps under compiz on the i915. I'm not sure if this is a purely a driver issue or partly my fault (not selecting the correct visual in e.g. gl-cairo-cube). All my transparent cairo-hacks work fine. Thanks in advance for your time and kind advice! Best regards... Mirco "MacSlow" M?ller -- email - macslow@bangang.de www - http://macslow.thepimp.net lowfat - http://macslow.thepimp.net/sponsor-it
Hi, In my ubuntu packages, to compiz work properly on AiGLX and for performance issue i continue to apply two patchs of Kristian H?gsberg : http://people.freedesktop.org/~krh/compiz-on-aiglx/compiz-patches/06-glfinish.patch http://people.freedesktop.org/~krh/compiz-on-aiglx/compiz-patches/02-tfp-server-extension.patch It's perhaps a mistake but they resolve many issues on AIGLX gandalfn Le jeudi 30 novembre 2006 ? 08:42 +0100, Mirco M?ller a ?crit :> Greetings everybody! > > For about two weeks I'm now a happy owner of an intel-powered laptop > (chipset, wifi, gfx) and wanted to give it a full test-drive of compiz > and other GL-intensive programs. > > The laptop runs Xorg 7.1.1 and the i810 driver that comes with it > (stock rpm from FC6).

Hi. I also experience a Compiz slow-down on my i915. However, I can run most apps fine, and Beryl is very smooth. Compiz always used to be better for me, but I don't know what has happened.
