Could rebuilding E in debugging mode help? probably not - btw - those shader exceptions might have to do with it. evas caches binaries for shaders. rm -rf ~/.cache/evas_gl_common_caches/ - but beyond that the only thing left is your driver. those are its shaders it compiled. google for it: "Graphics Exception: Shader Program Header 11 Error" seems to actually be OS independent and happen on windows too. https://forums.developer.nvidia.com/t/screen-system-is-dead-on-resume-unable-to-resume-with-all-current-drivers/29872/57?page=3 this has been there for a long time... and it seems it doesn't get resolved. https://github.com/Bumblebee-Project/Bumblebee/issues/739 it could be that evas uses egl+gles and the nvidia driver implementation for egl+gles is buggy - you can rebuild efl to use full desktop opengl+glx (-Dopengl=full). -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - ras...@rasterman.com _______________________________________________ enlightenment-users mailing list enlightenment-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-users
