Hello Friends:

After two days of working on this problem, which had several layers, I may be close, but need your help. When I run the following command to start the X-GUI display and XFCE4-based desktop; the many daemons all start, but the laptop screen goes blank. I can tell everything is running by ssh'ing into the laptop.

user@linux$ exec xinit ${HOME}/.xinitrc-xfce  <- start X using .xinitrc-xfce file (shown later)

As I walk you through this, everything looks great, yet something is missing or incorrect. Note that this laptop has been running Fedora 22, 23, 24, 25 with the proprietary NVIDIA driver for 2-years; no issues. This just started after a 'dnf update'.

See below. Any ideas? Thank you in advance.


Here is the issue captured in the log file. Notice where it says Could not find provider with name modesetting. Yet I show you later that it does exist.

Could not find provider with name modesetting  <-- # This exists in the filesystem (shown later).  

(xfsettingsd:2860): xfsettingsd-CRITICAL **: \
   Stored Xfconf properties disable all outputs, aborting. <-- # Could be caused by issue above.

Here is the '${HOME}/.xinitrc-xfce' file that I launched X with (above):

xrandr --setprovideroutputsource modesetting NVIDIA-0 <- This emits the "modesetting" error above.
xrandr --auto
synclient TapButton1=1 TapButton2=3 TapButton3=2
exec xfce4-session || exec xterm -fg red

And here we manually prove that NVIDIA-0 is a provider; but using modesetting is a problem.

user@y700$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x1b9 cap: 0x1, Source Output crtcs: 0 outputs: 0 \
   associated providers: 0 name:NVIDIA-0  <--- Good!

user@y700$ xrandr --setprovideroutputsource modesetting NVIDIA-0
Could not find provider with name modesetting   <--- Not Good. Why?

user@y700$ xrandr --auto

Hey, you wanna use nvidia discrete card only, so why are you trying to configure intel graphics and/or bumblebee? You have a system that can switch graphic card in bios, set it to nvidia and use it, no need for strange configuration settings.

Hi fcomida. You're correct but my laptop (a Lenovo Y700) only has two BIOS modes: "switchable" (dynamically switch between INTEL and NVIDIA) and "internal" (INTEL only). There is no "discreet" mode, sadly. As for bumblebee, I rarely use it. I have it just to test glxglears and other sanity checks every once in a blue moon, otherwise I forget the RPMs are there, and it's not enabled to start automatically. I just mentioned it for completeness. =:)
