No meu Xorg.0.log , existem essas linhas:
[ 36753.331] (II) LoadModule: "intel"
[ 36753.331] (WW) Warning, couldn't open module intel
e
[ 36753.331] (II) LoadModule: "radeon"
[ 36753.331] (II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so
O problema é que intel_drv.so e radeon_drv.so estão presentes, enquanto apenas um deles é carregado com êxito:
[c4thewin@LenovoG500-C4tW ~]$ ls /usr/lib/xorg/modules/drivers
ati_drv.so fbdev_drv.so intel_drv.so modesetting_drv.so radeon_drv.so vesa_drv.so
Eu também li que modprobe precisa de .ko bibliotecas como argumento, então ...
Não é modprobe que é executado nos bastidores?
Por que é que intel_drv.so não pode ser carregado mesmo que exista?
