As said in a previous post, I tried to make an ASUS N550 laptop (optimus) works with the proprietary nvidia driver, but failed.
But trying to revert to nouveau as more difficult than expected and finally the optirun option works worst than standard - glxsphere runs slower with optirun than without!!
Not easy to setup and understand.
Initially (yesterday :-), optirun glxspheres run at 160 frames / s approx, now at 32
Right now, I have 42.3 running in graphic mode but only in 1366x768 (I used to be 1920x1080) and optimus do not work, or only in software, so very slow.
I try to fix this (when I could reinstall the distrib), because it’s not the first time I have similar problem and I would like to solve it cleanly.
So there are two, may be unrelated problems: how to get again 1920x1080 and how to make bumblebee works. The later probably first.
Just at boot, I have

I still don’t find any solution and feel a bit desperate… So I will probably stop some days and come back later. Gladfully my work needing optirun is done for now.
Brief summary:
I buy second hand this ASUS N550 for a reasonable price two weeks ago
I replaced the windows 250 GB ssd by a 480Gb ssd with Leap 42.3 (fresh install)
I was a bit disappointed to see the screen couldn’t be set to full HD and noticed it was an optimus one
installed bumblebee, played some time with it
tested various external screens (TV set). One of them was a 24" screen I already know to be reluctant to display 1920x1080 but able to do, xrandr permitting and I could make it, I have it right now in front of me, full HD.
At some time during experiment, my laptop screen suddenly turned to work in full 1920x1080 with xrandr and nouveau. Good Surprise! optirun worked also to a bit more than twice the intel speed, so good. I could finish my video compiling work at full speed.
some days ago, some kind of update and I wanted to see if the proprietary driver could make a bit more speed. Deadly! Since then I can’t anymore make optirun work and my laptop screen is down to 1366x768.
One thing I noted and is curious. When it worked, my screen name was eDP-1. Now its eDP1 (without “-”). I even have this on my history:
> xrandr
Screen 0: minimum 8 x 8, current 3286 x 1080, maximum 32767 x 32767
eDP1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 340mm x 190mm
1366x768 60.06*+
(...)
so what is the update that Changed eDP-1 by eDP1 ?
Also, maybe you have something weird in your xorg.conf files (a remnant of previous tests?) since on a similar machine, but with 42.2, I see:
bruno@LT_B:~> xrandr
Screen 0: minimum 8 x 8, **current 1920 x 1080**, maximum 32767 x 32767
eDP1 connected primary **1920x1080**+0+0 (normal left inverted right x axis y axis) 350mm x 190mm
**1920x1080 60.02*+**
1400x1050 59.98
1600x900 60.00
1280x1024 60.02
1280x960 60.00
1368x768 60.00
...
As a last comment, please be aware that simply issuing:
optirun glxspheres
you actually get one screen per video refresh cycle, hence about 60 frames/sec (or about 67 Mpixels/sec on a 1920x1080 screen) as rendered by Intel Haswell mobile graphics.
To unleash the full potential of integrated graphics, as a benchmark, you should issue:
right now, to have it work, I have installed nouveau and nvidia driver, but with nouveau activated on bumblebee, nividia do not works. I still don’t have full HD.
the vblank_mode=0 trick is impressive (same result as yours). But for now I do not use optirun for display but with ffmpeg to convert videos. This give a 2x or 3x gain, but do not need a display.
My next use will be from kdenlive to display clips with effects, I didn’t test it yet
the problem is most certainly related to the kernel, my present system use the KOTD
linux-owxt.suse 4.14.0-rc1-3.g6627c5a-default
and then nouveau works but not nvidia, but this may be a driver problem, I will have to test rebuilding the nvidia driver with this kernel
Of course the Nvidia driver installed via the KMP is not going to work with a 4.14.x kernel and installing it “the hard way” is not guaranteed to work on a RC kernel either, as gogalthorp suggested.
But be aware that manual reclocking might be available with your GPU with the 4.14 nouveau driver, see this for a hint: https://forums.opensuse.org/showthread.php/522499-How-do-I-install-(nvidia-suse)-Prime-using-the-Nouveau-driver-on-my-Asus-Optimus-laptop?p=2810382#post2810382
If available, be careful to check temperatures and be prepared for occasional freezes (at least that was what I witnessed with kernels 4.9 and 4.10 at the time).
