Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

hi all finally i solved the problem. gem couldn't access the direct rendering infrastructure, because in my .pdrc pdp_opengl was loaded _before_ Gem. that means, it was not a problem during compile time, but it occured when loading the externals.

Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

hello, in order to know if your driver suport hardware acceleration, you can try : glxinfo | grep direct if it says yes : then you have hardware acceleration, so gem should use it. anyway, ubuntu do not distribute by default binary driver, so the opengl stuff is not very efficient. i think yo

Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

Hi Roman, I just wanted to get that out of the way. Just because glxgears runs doesn't mean that OpenGL is working and you actually have direct rendering. Sorry I can't help more, since I've never gotten ATI cards to work properly with Linux. Glad at least those work for you! ;-) best, d. R

Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

hi derek as i mentioned in the original post, i *have* accelerated graphics on my computer, so glxinfo tells me: 'direct rendering: Yes' the problem i have in this specific case, that i suspect gem not to make use of the hardware acceleration, for whatever reason. i don't know of reliable way to

Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

Hi Roman, Getting accelerated graphics from ATI cards on Linux has always been problematic with or without GEM. What does "glxinfo" (or "fgl_glxinfo"???) tell you? Look for the line which says: direct rendering: which should tell you "Yes" or "No". best, d. -- derek holzer ::: http://www
