Hi, ...it runs now at least for root (called as user it crashes still). I did the following: mv /usr/lib64/libGL.so /usr/lib64/off.libGL.so for all libGL.so* in /usr/lib64/libGL.so* Addtionally I added 06nvidia to /etc/ld.so.config.d/. with this contents: /usr/lib64/opengl/nvidia/lib and did a ldconfig afterwards and reboot to release any filehandle. One question remains: It works for root but not for any other user. I (as user) am in the video group. I checked the directory/file permissions of opencascade and they seem to be ok. I straced FreeCAD...but...I fear not to see anything suspicious because the output contains a lot of noise (much more as normally seen in such traces)... The eselects show: >eselect opengl list Available OpenGL implementations: [1] nvidia * [2] xorg-x11 >eselect mesa list i915 (Intel 915, 945) i965 (Intel GMA 965, G/Q3x, G/Q4x, HD) r300 (Radeon R300-R500) r600 (Radeon R600-R700, Evergreen, Northern Islands) sw (Software renderer) [1] classic [2] gallium * Why is nvidia not listed with the second command? Any ideas? Cheers Meino
