| 8 | To use 2D Video Acceleration within Oracle VM VirtualBox, your host's
|
|---|
| 9 | video card should support certain OpenGL extensions. On startup,
|
|---|
| 10 | Oracle VM VirtualBox checks for those extensions, and, if the test
|
|---|
| 11 | fails, this option is silently grayed out.
|
|---|
| 12 | </p>
|
|---|
| 13 | <p>
|
|---|
| 14 | To find out why it has failed, you can manually execute the
|
|---|
| 15 | following command:
|
|---|
| 16 | </p>
|
|---|
| 17 | <pre xml:space="preserve">$ VBoxTestOGL --log "log_file_name" --test 2D</pre>
|
|---|
| 18 | <p>
|
|---|
| 19 | It will list the required OpenGL extensions one by one and will
|
|---|
| 20 | show you which one failed the test. This usually means that you
|
|---|
| 21 | are running an outdated or misconfigured OpenGL driver on your
|
|---|
| 22 | host. It can also mean that your video chip is lacking required
|
|---|
| 23 | functionality.
