you have some nasty problem there. what - i don't know. i have seen absymal performance on fglrx before, but never nvidia EXCEPT when the driver has leaked. there used to be a problem where it would leak resources internally and eventually slow down to a crawl. you had to kill the xserver to fix it up. restarting e wouldn't do it (or logging out and in without the xserver process getting re-executed). all i can imagine is it's either: 1. a specific issue in your nvidia driver version that i've never seen (it's incredibly new, or its really old or just a version i never hit). and/or 2. its an issue with your xorg server version that causes this OR somehow via interaction with the nvidia driver produces this. and/or 3. some kernel change/bug that affects the nvida drivers on every ubuntu version i remember running e17 on with compositing via gl in evas (10.04. 10.10, 11.04) it has worked a charm - with 10.04 eventually leaking as above. all i can suggest right now is "change distribution and see". that'll change the 3 things above to at least match something i have seen before, but as such there is nothing we can really do to help without you narrowing down the condition that causes the issue, and i believe that issue is probably one or more of the 3 above. > There is also an "engine" screen that has a "Use ARGB instead of shaped > windows" > > I have tried both on and off. you want that on when compositing. off will hurt performance bandly. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
