Hi Marc

Can you attach your xorg.log, the link provided returns a 404

What is the output of
$ DRI_PRIME=1 glxinfo | grep render

Note that Optimus is a very "funny" case and your experience may vary
depending
on the connections between the GPUs and the outputs - special thanks goes to
your laptop manufacturer :)

For further information take a look at our wiki [1]

Hmm something unusual is happening here

* the var/messages does not indicate any writes to vgaswitcheroo/switch
* the Xorg.log still indicates that the intel card is setup and used as primary

So to get a better picture (including timeline) can you do the following

1. Toggle/switch to the nv card
$ cat /sys/kernel/debug/vgaswitcheroo/switch 
$ echo "0000:01:00.0" /sys/kernel/debug/vgaswitcheroo/switch

2. Confirm that the nv card is used (paste the output in your reply)
$ cat /sys/kernel/debug/vgaswitcheroo/switch 

3. Start X
$ init 5 #startx # systemd start {g,k,x}dm

and then attach the output of the following (plain text, please)

* dmesg
* Xorg.0.log
* LIBGL_DEBUG=verbose glxinfo
* LIBGL_DEBUG=verbose DRI_PRIME=1 glxinfo

Thanks

cat /sys/kernel/debug/vgaswitcheroo/switch 
0:DIS: :Pwr:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0

don't seem switched?

i tried
echo DIS > /sys/kernel/debug/vgaswitcheroo/switch

but the screen get completly black...

so i switched back with 
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch

With "screen" I believe that you're talking about the laptop LVDS?

In that case it seems like the nv card is not wired to that output, thus
you'll
need to do the following

* forget about vgaswitcheroo
* Follow the instructions on our wiki [1]

Is this still an issue with newer kernels? (e.g. 3.13.x or newer)

no answer for a long time plus offloading works fine with newer version of the
kernel today, so i assume this is fixed.

Feel free to reopen the bug if the problem persists...
