If you're affected, unplugging displayport monitors will fix it temporarily.

To downgrade to a working version, I did the following : 

```
xdowngrade /var/cache/xbps/nvidia-460.56_1.x86_64.xbps /var/cache/xbps/nvidia-libs-460.56_1.x86_64.xbps /var/cache/xbps/nvidia-gtklibs-460.56_1.x86_64.xbps /var/cache/xbps/nvidia-dkms-460.56_1.x86_64.xbps /var/cache/xbps/nvidia-libs-32bit-460.56_1.x86_64.xbps /var/cache/xbps/nvidia-opencl-460.56_1.x86_64.xbps
dkms uninstall -m nvidia/460.56 -c void-packages/srcpkgs/nvidia/files/dkms.conf --force
dkms install -m nvidia/460.56 -c void-packages/srcpkgs/nvidia/files/dkms.conf --force
```
