[SOLVED] startx doesn't work with Nvidia Optimus

For about a week now, I've been trying to get Xorg working on my Lenovo Thinkpad P1 that has both integrated Intel graphics as well as a Nvidia Quadro P1000 Mobile graphics card.  I have the packages nvidia and xf86-video-intel installed, as well as optimus-manager and i3, and the last line of my .xinitrc is exec i3.  My initial issue was that running startx, Xorg -configure, or lspci would cause my computer to shutdown after hanging for a bit.  I managed to fix this by following the advice given here creating /etc/modprobe.d/blacklist.conf and adding

install i915 /usr/bin/false
install intel_agp /usr/bin/false

after adding this file and rebooting, my computer no longer shuts down when I run any of the above commands, but now running startx results in an error spread across several lines. (it looks something like this)

xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)
Fatal server error: no screens found
Please consult The X.Org Foundation support at http://wiki.x.org for help.
Please also check the log file at "/home/devyn/.local/share/xorg/Xorg.0.log" for additional information.

The full Xorg.0.log file is here; at the top of the file is the line

(WW) Failed to open protocol names file lib/xorg/protocol.txt

I don't know if that warning is relevant or not, but from the first error to the end of the file is as follows:

After spending about a week trying to figure this out, the only reason I still have hope that I should be able to make it work is that Manjaro was installed previously and worked fine.  If any other files or outputs are needed, let me know; any help is appreciated.

Re: [SOLVED] startx doesn't work with Nvidia Optimus

The advice to blacklist your intel modules is wrong (in general, you should ignore the normal nvidia article on optimus), Optimus works by relaying your nvidia image over your intel card you have to have the intel modules loaded. Remove xf86-video-intel, remove any xorg configuration you tried to generate, then read https://wiki.archlinux.org/index.php/NVIDIA_Optimus and don't do anything that isn't explicitly mentioned there as a possibility (and do not mix and match, chose one approach)

If we continue to assume Optimus Manager and heeding that advice from the xorg log, post

pacman -Qs nvidia
pacman -Qs libgl
pacman -Qs linux
systemctl status optimus-manager
uname -a
dmesg

and while we are at it maybe your actual .xinitrc.

Re: [SOLVED] startx doesn't work with Nvidia Optimus

Looks like you did not add the following lines to the start of your .xinitrc

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

I have a similar laptop (X1 Extreme), following the NVIDIA graphics only part here https://wiki.archlinux.org/index.php/NV … phics_only solved the same issue for me.

Re: [SOLVED] startx doesn't work with Nvidia Optimus

Yeah just read up on it, optimus manager is only really intended to be used with display managers. If you want to use .xinitrc you will want to remove/disable it and use direct .xinitrc adjustments as mentioned above (or keep it but remember to comment/uncomment the two xrandr lines, and run the relevan optimus-manager switch command so that proper module blacklists are generated...)

Re: [SOLVED] startx doesn't work with Nvidia Optimus

Thanks for the help; it's finally working!  I followed the advice for NVIDIA graphics only, as well as deleted optimus manager, restored the intel blacklist (I couldn't run lspci otherwise), and I also changed the settings in bios to run with discrete graphics only.  Now that Xorg is working, I can spend the next week configuring i3!!
