Fedora 23 NVidia issues

[bosim]

Hm. I like Fedora is close to upstream, but maybe it is a bit too close to use a development version of a core component in a release (I know the 23 release is not final yet). So whenever 1.18 is released we can expect drivers?

Nvidia has been releasing updates in a somewhat monthly manner. The latest update was last week,
so in roughly a months time there may be another.

Related to this. Do you guys know some tool, a script, instruction-URL or method to easily change between nouveau and nvidia X-system without needing of uninstall and install rpm packages from repositories?


I've tried to test nouveau with X v1.18 , but just cannot get it to work. In the net "they" say all nvidia-libraries and drivers has to be removed, or nouveau may not work. Well, I wonder if there is easier way to do it.

Below is a failed nouveau Xorg-session Xorg.0.log (Xorg v 1.17 there because it works also with nvidia)

nvidia kernel driver was not loaded. nouveau kernel driver was loaded.
And I had "/usr/lib64/nvidia/xorg" renamed as "xorg.not" so nvidia libraries wouldn't be loaded.
/etc/X11/xorg.conf was soft link to -> xorg.conf-nouveau, which should be ok.

It has been long time I've used nouveau last time. Googling around, I think having "GRUB_GFXPAYLOAD_LINUX=text" in /etc/default/grub is the problem here?
Should I just comment it out?

# cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_CMDLINE_LINUX=" root=/dev/mapper/ .... (and so on)
GRUB_DISABLE_RECOVERY="false"
GRUB_GFXMODE_LINUX=1280x1024
GRUB_TARGET=x86_64-efi
