Hi all, I installed bumblebee to support my nvidia GT-620m card, but failed to use optirun sometimes. Here are some details. When I use "optirun firefox", it works fine. But when I use it to launch "wine osu!.exe"(a game), it fails. and I got these outputs: /------------- |[VGL] WARNING: The OpenGL rendering context obtained on X display |[VGL] :8 is indirect, which may cause performance to suffer. |[VGL] If :8 is a local X display, then the framebuffer device |[VGL] permissions may be set incorrectly. |[VGL] WARNING: The OpenGL rendering context obtained on X display |[VGL] :8 is indirect, which may cause performance to suffer. |[VGL] If :8 is a local X display, then the framebuffer device |[VGL] permissions may be set incorrectly. |[VGL] ERROR: glXCreateContextAttribsARB symbol not loaded \------------- Then I tried "optirun --debug glxgears", it also failed to start. The ouputs were: /------------- |[ 1826.023482] [DEBUG]optirun version 3.2.1 starting... |[ 1826.023552] [DEBUG]Active configuration: |[ 1826.023577] [DEBUG] bumblebeed config file: /etc/bumblebee/bumblebee.conf |[ 1826.023601] [DEBUG] X display: :8 |[ 1826.023623] [DEBUG] LD_LIBRARY_PATH: /usr/lib/nvidia:/usr/lib32/nvidia |[ 1826.023645] [DEBUG] Socket path: /var/run/bumblebee.socket |[ 1826.023665] [DEBUG] Accel/display bridge: auto |[ 1826.023687] [DEBUG] VGL Compression: proxy |[ 1826.023709] [DEBUG] VGLrun extra options: |[ 1826.023730] [DEBUG] Primus LD Path: /usr/lib/primus:/usr/lib32/primus |[ 1826.023819] [DEBUG]Using auto-detected bridge virtualgl |[ 1829.389796] [INFO]Response: Yes.

I googled "358: GL_ARB_pixel_buffer_object extension not available", only got this[1], which was useless for me. I also googled ":8 is indirect, which may cause performance to suffer", but got nothing helpful as well. Here are some more details.
