Re: [gentoo-user] trying to use Nouveau

[T BkRl]

I’m not sure if xorg is the only thing at fault. I’ve had issues in opensuse and mint where if I force nouveau it kernel panics during boot. Otherwise it loads Nvidia.

I've created a file /etc/X11/xorg.conf.d/10nouveau.conf ,
which reads as above (apart from the "options" line, which is omitted) ;
I use spaces, not tabs. I've tried all 4 permutations
of "Card1" / "Card0" & "modesetting" / "nouveau".
I also tried naming it '99...' : there's a '20opengl.conf', which says :

Section "Files"
ModulePath "/usr/lib64/xorg/modules"
EndSection

I've also recompiled xorg-drivers , then xorg-server :
the former now has the USE flag 'nouveau'. I've rebooted between trials.

Every time, Nvidia starts :

Is 'udev' getting entangled in this at some point ?

Does anyone have any further advice ? Thanks so far.
