Alack-and-alas, the nvidia installers /etc/modprobe.d/ nvidia-installer-disable-nouveau.conf entry:
# generated by nvidia-installer
blacklist nouveau
options nouveau modeset=0
... resulted in blank screens on reboot. I was able to type blind and login on tty1 and issue a 'sudo reboot' command ...

Thanks ElderDryas (great profile pic, btw), I'll give it another go by re-enabling nouveau and letting the nVidia software pave its own way.

Sidenote: When I went to disable nouvea the second time (after re-enabling to compare) glapt only showed the blacklist option. Here's a screenshot: http://www ...

"Second verse, same as the first" ... I re-installed 'xf86-video-nouveau-blacklist-noarch-1' and rebooted. Same as before, I am now unable to get a display in tty consoles. :cry: sigh ...

The question remains, since I've again blacklisted nouveau (and rebooted) what driver is currently providing ...

I reinstalled 'xf86-video-nouveau' and now have access to tty(1 - 3) consoles back.

Bit of a 'Catch 22' at this point ... I guess I'll try the process again (making sure to reboot after blacklisting and before launching nvidia) to see if it changes anything.

Hoping to sort this out. I really need ...

note: I've recently also experienced being unable to access tty consoles when trying to install Manjaro and Solyd X (and may have happened with lubuntu 14.04, don't recall for sure, I've done a helluva' lot of install attempts in the past week). But those distros also were showing other (more ...

"Toto, Toto, this don't look like Kansas" ... Uh, after blacklisting the nouveau driver and rebooting (I'm aiming to install an nvidia binary driver) I was unable to bring up a screen on tty1 ('alt+ctl+F1' from 'gdm' greeter). My screens just go blank and suspend. I was able to 'alt+ctl+F7' back to ...

Ah, after going back and rereading the wiki entry I see that exiting the GUI isn't a concern until just before installing the nVidia driver. So apparently downgrading the Janus-faced beast ... err ... "xf86-video-nouveau" ... via Gslapt would likely be fine. I think I'll just do it all from an ...

Ah, I see. The actual package (via 'sudo slapt-get --search nouveau') is "xf86-video-nouveau-blacklist-noarch-1", not "xf86-video-nouveau-blacklist" as given in the wiki:
Blacklisting nouveau

Run the following as root:
slapt-get --update
slapt-get -i xf86-video-nouveau-blacklist

Would someone ...

Ah, gui to the rescue for a change...

... The blacklisting package has apparently been given the same name* as the driver. :shock: DOh! :o

p.s.— I've perused: http://forum.salixos.org/viewtopic.php?f=16&t=5186&p=33424&hilit=nvidia+nouveau+blacklist#p33424 but haven't succeeded in deriving a clear way to proceed from it.

Tips-n-tidbits would be most welcome. Nouveau doesn't play nice with one of my monitors and I need VDPAU support ...
