as posted a short while ago, I have a new Acer Aspire E5-575G-55DE
laptop and am trying to get C7 running on it.
This laptop has an intel i5-6200U with integrated HD Graphics 520. It
also has an nvidia GeForce GTX 950M.
Installing kmod-nvidia and bumblebee as explained  results in the "Oh
no! Something has gone wrong" screen. I suspect that's because the
regular C7 kernel and xorg-x11-drv-intel don't support the intel 520.
Booting into kernel-lt, it seems the intel 520 works...? This is
surprising because Farkas Levente's recent post to this list suggested
that a newer xorg-x11-drv-intel should be needed, in addition to the
newer kernel. But I have a bunch of OK-looking intel messages in
/var/log/Xorg.0.log , and glxinfo says:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Skylake ULT GT2
Question 1: does this mean the intel 520 works fully under kernel-lt? If
not, what should I look at?
Assuming the intel GPU works under kernel-lt, I could then hope to get
nvidia and bumblebee working. I've been using the elrepo nvidia drivers
for ages, but I could use the nvidia-provided installer and hope it
doesn't clobber anything (which I doubt...).
Question 2: any caveats here?
Finally I would need to get bumblebee working, otherwise the nvidia
stuff is useless. However, bumblebee requires kmod-bbswitch...
Question 3: I guess I would have to rebuild bbswitch  for kernel-lt,
but could I still use the elrepo-provided bumblebee ?
Thanks for any advice anyone can provide.
