Re: [gentoo-user-br] Erro de permissao no DRM

[Alain Dellon Brito]

Fabiano, se o problema for o udev, dê uma olhada no /etc/udev/rules/50-
udev.rules

verifique se seu dispositivo está configurado da seguinte forma:

# dri devices
KERNEL=="card*",        NAME="dri/card%n", GROUP="video"

um abraço,

Dellon
