Up to now I had used Intel HD4000 graphics built into the processor, and was using xorg-edgers drivers (mesa and video-intel). Now I have switched to discrete nVidia graphic card and I simply installed nVidia-common from the repositories, I'm seeing nVidia xserver settings and nv-xserver is reporting opengl4.3 and
direct rendering:yes and some apps work correctly but some fail to do so; resulting in this command:
LIBGL_DEBUG=verbose glxinfo | grep -i -A 5 -B 5 direct is giving this in terminal:
libGL: screen 0 does not appear to be DRI2 capable libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so libGL error: failed to load driver: swrast name of display: :0 display: :0 screen: 0 direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) server glx vendor string: NVIDIA Corporation server glx version string: 1.4 server glx extensions: GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
I tried to purge and reinstall xserver-xorg and used
dpkg-reconfigure xserver-xorg but the same error remains.
Any help or advice would be appreciated.
