[SOLVED] Need help with optimus laptop

I have an msi ge62 6qd apache pro laptop with a hybrid intel/ nvidia gtx960m
now i have tried linux mint on it (17.3 rosa) and it does work well so i know
it is possible to do make this work. I am just trying it with slackware because
i like more of a source based distro i find it is more powerful (and challenging)
Right now i am using slackware current as of this posts date and have already installed the current bumblebee according to the automated script on this site
here: http://docs.slackware.com/howtos:har...nvidia_optimus
the install was easy enough although functionality was a bit of an issue. All but
the option "none" for PMMethod in bumblebee.conf locked up my laptop. And when i used "none" for PMMethod using startx to start x-windows crashed it with this Xorg.0.log output:

this is after i modprobed nvidia without an error and when i do an lsmod i do not
see the module.

Sorry if this is too much information, i am just hoping some one has some advice
on this one.

Did you tried without any xorg.conf file ?

Could you post the lsmod output ?

Yes i did try without an xorg.conf and did not get a working xorg, the server crashed out. As for the lsmod question:

now that is from my laptop as of now with linux mint 17.3 rosa running on it and is an ideal lsmod for my setup.
here is my other thread for more info on this:
http://www.linuxquestions.org/questi...un-4175562867/

sorry for the confusion i had to post there first

I finally managed to get xorg to work with the optimus on slackware current but it was unstable and needs a lot more work.
An up to date kernel and a sufficiently updated x11 software stack will work even without an xorg.conf file however it is
possible to get nvidia to work with a properly made xorg.conf but bumblebees power management had to be shut off. Glxinfo
when activated by optirun does show nvidia is working but glxgears is slower for some reason then intel as well as the mouse
wheel being really sluggish in firefox and opera but not in konqueror. In any case i went back to linux mint 17.3 rosa for now
because i have better support for my msi laptop, but i still love slackware.

The error when you tried to start X was due to missing nvidia module. Did you build and install the proprietary nvidia driver and kernel module?

Oh yeah i did have nvidia built and installed not a problem there, if you look at my last post i even indicate that i managed to get it
working just not very well. software stack needs tweaking. In time i am sure this will happen and my hardware will be fully supported.
Yeah xorg log files can be informing but misleading by themselves, you gotta see the bigger picture.

Success!! well mostly anyway. I did an install of slackware and updated to current (14.2) with a linux-4.4 kernel.
I can tell you there is a definite speed up on the skylake chipset, but in order to boot it up i had to add "intel_idle.max_cstate=1"
to the boot options in grub to get it to not lock up and intel preliminary hardware support for the intel graphics driver has to be
enabled as well. Bumblebee had to be used to control optimus and power management for bumblebee had to be set to none or
a lock up occurred. 3-d performance was there just not very consistent. Glxgears with vsync to blank set to off gave a higher frame rate with unaccelerated glxgears than it did with either primusrun or optirun glxgears!. An accelerated wine run windows game like
Diablo II ran Awesomely in unaccelerated mesa, better than it ever did for me but crapped out on primusrun even though primusrun glxinfo indicated that nvidia was working. Still potential is seen here even if work still is in progress . Pulseaudio working out of the box was also nice as well with the update. Perhaps a port of the nvidia-prime/applet from linux mint/ubuntu would be a more
effective and convenient way of contolling optimus in this case. A few more tweaks is all that may be needed.

Sigh. Well it looks like i much cracked this one. Pretty much stable now. First i tried bumblebee and that works, no horizontal tearing but it is a bit kludgy and
i like some thing a little simpler in implementation like prime sync. Well simpler it was not and it took a bit of doing. First i had to update xorg and for that i downloaded xorg source from slackware current fulfilled its' dependencies and installed it. Then i installed linux-4.10.13 along with the nvidia-drivers from nvidia
(which had to be patched to compile, ubuntu has a patch for it) the 375.59 version. So software stack and kernel are newer and it should work. Not just right yet but almost.
With out a correct .xinitrc and xorg.conf you get a black screen, which is what i had until i corrected these oversights.
.xinitrc is in effect:

# try this in a seperate terminal when xorg is started
#xrandr --output eDP-1-1 --set 'PRIME Synchronization' '1' # is prime sync on !
#xrandr --output eDP-1-1 --set 'PRIME Synchronization' '0' # is prime sync off
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
xrandr --dpi 96
ck-launch-session dbus-launch --exit-with-session startkde

and i used the xorg.conf from :
https://askubuntu.com/questions/9002...ing-screentear

And finally i got screen! and with prime sync too when i used:
"xrandr --output eDP-1-1 --set 'PRIME Synchronization' '1' "

"xrandr --verbose" will tell you what you have and i had what i was looking for.

No more primusrun or f%$^& optirun either.
But i had to set the desktop effects compositing type to xrender and the qt graphics system to native to because for some reason kwin doesn't deal
so well with prime sync and you get GL errors when the laptop sleeps and an unstable desktop if you don't change these things. Still this is worlds better
and i have not had much of a problem since i mad these changes and my opengl games like in steam and wine seem to be pretty stable so far. So i am anticipating
eventual stable prime sync out of the box for most if not all optimus laptops with slackware. Now try this with multilib and see how you like it.
No this has not been without its problems but i like to experiment and as i said already i think this will be stable out of the box eventually.
