Unable to run on ubuntu 18.04

[Neil-HD]

I have installed this on ubuntu 18.04 and it did not work. Looking at the log files, this was most likely becuase of several module paths being wrong. As i corrected module paths , gradualy, more and more code ran but the system never functioned. I have attached log files, of the initial unchanged path run, the second run, where i changed the first two paths, and the final run that ive done so far first.log second.log thrid.log

here is the current edited path files that I have been using.

`Section "Files"

ModulePath "/usr/lib/x86_64-linux-gnu"

ModulePath "/usr/lib/i386-linux-gnu"

ModulePath "/usr/lib/xorg/modules/drivers"

ModulePath "/usr/lib/xorg/modules"

ModulePath "/usr/lib64/nvidia/xorg/modules"

ModulePath "/usr/lib64/nvidia/xorg"

ModulePath "/usr/lib64/xorg/modules"

EndSection ` Incidentally, is there any documentation on what each path is supposed to point to?

i have just added ModulePath "/usr/lib/nvidia/xorg/modules"

ModulePath "/usr/lib/nvidia/xorg"

ModulePath "/usr/lib/xorg/modules" and it works (debian but should work on ubuntu too

Yeah, there is no /usr/lib64 in my Ubuntu 18.04 installation. I assume all of those are in /usr/lib considering it's a 64-bit installation and there's a separate /usr/lib32 for 32-bit libraries.

For Ubuntu, it seems NVIDIA's proprietary driver will install to /usr/lib/x86_64-linux-gnu/nvidia instead. After changing the paths in /etc/X11/nvidia-xorg.conf and /etc/X11/xinit/nvidia-xinitrc accordingly, unfortunately I'm still unable to get it to work. For the latter file, I had to edit the path in this line specifically: https://github.com/Witko/nvidia-xrun/blob/b8bd592d4727852dfd2cca8c23fe7e2312a93dc1/nvidia-xinitrc#L26 Basically from /usr/lib64/nvidia/ to /usr/lib/x86_64-linux-gnu/nvidia/.

Here's a gist of my latest Xorg log file: https://gist.github.com/BobbyWibowo/d8a5db1c6ead2bafdd8587ce5d7c30bb.

Another thing to note, after it fails to do its thing once (the log is above), all tty's will be spammed with these errors roughly every second: https://i.fiery.me/yfZC.mp4 (~7s video).

Ok, purged out bumblebee and reinstalled nvidia driver. Now I got it to only output:

[ 99.407] xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)

when failing. Here's the full log: https://gist.github.com/BobbyWibowo/9bfb6c91d6e17ee3f3054445862ea5e5. There were no other (EE) lines, so I legit have no idea what else to attempt to fix. Something that got me concerned are these lines:

[ 99.399] (**) OutputClass "Nvidia Prime" ModulePath extended to "/x86_64-linux-gnu/nvidia/xorg,/usr/lib/x86_64-linux-gnu/xorg,/usr/lib/x86_64-linux-gnu/nvidia,/usr/lib/x86_64-linux-gnu/nvidia/xorg/modules,/usr/lib/x86_64-linux-gnu/nvidia/xorg,/usr/lib/xorg/modules"
[ 99.399] (**) OutputClass "Nvidia Prime" setting /dev/dri/card1 as PrimaryGPU

They sound as if there were some leftover configurations from PRIME that sorta screwed the whole things up, but I was sure I already purged out nvidia-prime package.

-- edit -- Was not from nvidia-prime package, but instead an auto config from gpu-manager. Harmless.

Oh thanks lord the almighty, I've finally got this working very well. The issues/speculations in my previous reply doesn't appear to be any breaking issues (or perhaps were not issues in the first place). I still see them on my X log despite everything working great. As for the issue in my reply before it, it was probably just due to me having quite dirty configurations. I also still had bumblebee installed back then (yes, I've purged out bumblebee, don't need it).

-- edit -- Forgot to mention that I ended up using 0.3 stable release. Latest git commit, https://github.com/Witko/nvidia-xrun/commit/b8bd592d4727852dfd2cca8c23fe7e2312a93dc1, is no longer using bbswitch, and the alternative in it appears to be somewhat quirky on my machine. Stable is still using bbswitch, but hey, it works.

@BobbyWibowo could you please upload your /etc/X11/nvidia-xorg.conf and /etc/X11/xinit/nvidia-xinitrc files? I'm getting xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted) in my log as well

[BobbyWibowo]

@Quintasan Here you go: nvidia-xorg.conf: https://gist.github.com/BobbyWibowo/a10ac8fb77e9521987f1bf543e7d580f nvidia-xinitrc: https://gist.github.com/BobbyWibowo/ab6ccb09a305eb6f3f488d065be4bae1

Also, you may want to consider using these combination of nvidia-xrun + nvidia-toggle scripts: nvidia-xrun: https://gist.github.com/BobbyWibowo/09de27597520bb4bb1d816c15f40f9f5 nvidia-toggle: https://gist.github.com/BobbyWibowo/c7f97bca11e37502be350733b2236e94 /etc/default/nvidia-toggle: https://gist.github.com/BobbyWibowo/b5ac9339b0e9b81bb00d3debedf71f7b I split the parts that needed sudo into nvidia-toggle so that I can add that script only into sudoers file, to avoid entering sudo password every single time.

These will use bbswitch instead of writing to the system file interface kinda thing (the current method in this repo). I can't remember why, but for some reason I couldn't get the card to turn off when not in use without using bbswitch.

I also stopped using modeset=1 flag due to some issues back then, but by now I can't recall a single thing what the issues were, lmao. One thing I know for sure, without the flag I'll get screen tearing, but I convinced myself that it was a better trade-off than the issues that I'd get with the flag on; not that I can recall what the issues were..

@BobbyWibowo unfortunately bbswitch doesn't seem to like my device, I get no such device when trying to insmod bbswitch :(.
