note: |
| 20 |
This utility switch between OpenGL implementations. Currently there |
| 21 |
are three supported implementations, namely "xorg-x11", "nvidia", and |
| 22 |
"ati", the implementations for X.Org, and the NVidia and ATI drivers |
| 23 |
respectively. |
| 24 |
|
| 25 |
examples: |
| 26 |
opengl-update-livecd xorg-x11 |
| 27 |
This will setup things to use libGL.so from X.Org |
| 28 |
|
| 29 |
opengl-update-livecd nvidia |
| 30 |
This will setup things to use libGL.so from the NVidia drivers. |
| 31 |
|
| 32 |
opengl-update-livecd ati |
| 33 |
This will setup things to use libGL.so from the ATI drivers. |
