Hi, thanks for the advice. Sine Blender is heavily using CUDA and the nvidia card to render (cycles), I have to use nvidia-drivers, nvidia-settings and the nvidia-cuda-toolkit. So I want to step back one release of the drivers, because that had worked fine for me. Older ebuilds fo nvidia-drivers are provided...but why all older ebuilds except for the newest one of nvidia-settings and nvidia-cuda-toolkit are wiped off my harddisc as soon I have upgraded to a (for me) not wirking nvidia-driver-ebuild? Any chance to go back or ma I urged to live with described """features""" or to quit blender and use the noveau-drivers? Best regards, mcc
