well you have other issues. you get the above when the gl engine doesn't work (or just isn't there). but wait... Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx integrated Graphics Controller ... that i think is the GMA3150 ... and that intel gpu is just plain junk. it has no vertex shader (fragment shader only) and will run like garbage with evas ... because evas actually throws lots of triangles at a gpu. we require shaders. the drivers actually from memory LIE and fake shaders with software emulation of the vertex shaders and that's what leads to horrible performance. so i think whats happening is init is just failing some time during shader setup because of this. details would require some digging... but basically "you gpu is far too bad/old, so no gpu acceleration for you". that gpu is from like 2009 ... and it was like one of the worst ones at the time. the embedded gpu's (mali, imgtec) on phones were fare better than the gma3150. they did vertex shaders. phones in 2009/2010 were better than this intel atom and its gpu at the same time. the nvidia, ati etc. gpu's were streets ahead of this gpu back in 2006/7 or so. you have one of the single worst gpu revisions ever... :) get a newer (or even older one that is not intel) ... :) -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- The Rasterman (Carsten Haitzler) ras...@rasterman.com ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
