Your system is using the nouveau driver. You need to disable it and only |
| 23 |
enable the nvidia driver. In your make.conf, change this: |
| 24 |
|
| 25 |
VIDEO_CARDS="nvidia nouveau" |
| 26 |
|
| 27 |
to: |
| 28 |
|
| 29 |
VIDEO_CARDS="nvidia" |
| 30 |
|
| 31 |
Also, add "nvidia" to your make.conf USE flags (this might not be |
| 32 |
actually needed, but better safe than sorry.) |
| 33 |
|
| 34 |
Then also see if you have nouveau enabled for something elsewhere in |
| 35 |
your portage configuration. Do this: |
| 36 |
|
| 37 |
grep -r nouveau /etc/portage |
| 38 |
|
| 39 |
This should print nothing. If it does, then you should edit the files |
| 40 |
and disable nouveau. |
| 41 |
|
| 42 |
Finally, tell portage to check what needs to be re-emerged due to these |
| 43 |
changes: |
| 44 |
|
| 45 |
emerge -auDN --with-bdeps=y @world |
| 46 |
|
| 47 |
Reboot. |
