again,
<br>
<br>
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.
<br>
<br>
This laptop has an intel i5-6200U with integrated HD Graphics 520.
It also has an nvidia GeForce GTX 950M.
<br>
Installing kmod-nvidia and bumblebee as explained [1] 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.
<br>
<br>
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:
<br>
OpenGL vendor string: Intel Open Source Technology Center
<br>
OpenGL renderer string: Mesa DRI Intel(R) Skylake ULT GT2
<br>
<br>
Question 1: does this mean the intel 520 works fully under
kernel-lt? If not, what should I look at?
<br>
<br>
<br>
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...).
<br>
Question 2: any caveats here?
<br>
<br>
Finally I would need to get bumblebee working, otherwise the
nvidia stuff is useless. However, bumblebee requires
kmod-bbswitch...
<br>
Question 3: I guess I would have to rebuild bbswitch [2] for
kernel-lt, but could I still use the elrepo-provided bumblebee ?
<br>
<br>
<br>
Thanks for any advice anyone can provide.
<br>
Regards,
<br>
Nicolas
