Can't get multiple displays with Nouveau drivers
Since installing Fedora 25, I have never been able to get multi-monitor support to work without installing Nvidia's proprietary drivers. Furthermore, when I'm on Nouveau, my cinnamon environment warns me that it has reverted to software rendering as a result of some issues with video drivers. Now that Nvidia drivers have begun causing serious issues (and I hate the idea of 'proprietary' drivers in Linux), I have uninstalled Nvidia and am trying to solve how to get Nouveau to play ball. I am on a GTX 900 series, and followed the RPMFusion Guide to a tee. I also cleared blacklisting out of grub cfg and rebuilt grub successfully, and the driver appears to load:
lsmod |grep nouveau
Reveals several entries
modprobe nouveau
Shows no errors.
grep nouveau /etc/modprobe.d/*
Shows no blacklisted entries.
Also it appears that X server is doing its job:
$ cat /var/log/Xorg.0.log | grep nouveau
[ 36.123] (==) Matched nouveau as autoconfigured driver 0
[ 36.123] (II) LoadModule: "nouveau"
[ 36.123] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so
[ 36.126] (II) Module nouveau: vendor="X.Org Foundation"
Does anyone have any advice? Thank you.
