Installing 4.4 rc7 kernel yields i915 module not available
Solution 1
I could solve the error, by downloading the missing module here: https://01.org/linuxgraphics/downloads/sklgucver43
Unfortunately I am doubtfull this solves everything, play I play avideo in VLC with graphics acceleration (overlay mode), I can still not resize the video, but I will open a separate request for this.

Solution 2
I replaced curl with wget and this worked perfectly in regards to Possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module i915
curl -O http://de.archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157_all.deb
dpkg -i linux-firmware_1.157_all.deb
sudo update-initramfs -u -k all

Dears, I installed the 4.4 rc7 kernel on my ubuntu 15.10 following this page github.com/awesomebytes/ubuntu14_dell_xps13_9350 just replacing code for rc6 with code for rc7.
when installing I got an error message that i915 was not found, as this seems linked to 3D acceleration, I am a bit worried that I am loosing some performance. What could/should I do ?
according to first comment I now installed rc8, I still used the same install script as in the link above.
Here is the output

It seems that the i915 is at the end of the script on this part
sudo bash -c "echo 'i915 nvme' >> /etc/initramfs-tools/modules" sudo update-initramfs -u -k all
It also yields some more issues before as well, but which seems less of a worry (DKMS is driver for the usb wifi dongle which I don't need anymore).
Thx, Timothé

Doug Smythies over 8 yearsTry Kernel 4.4-rc8. Due to some issues there was a delay before they got posted on the mainline ppa. However, the successful rc8 builds just got posted about an hour ago.

Timothe Jahan over 8 yearsHi I did not mark down the error at the point I installed the kernel. I do have the i915.ko file and I get some results when doing modinfo i915.ko, but nothing that looks like a logfile. Note, this comment is with the rc7

Doug Smythies over 8 yearsI do not think the file
skl_guc_ver4.bin
is included in 15.10 linux-firmware. It is included in 16.04 linux-firmware. I do not know if this is your root issue or not. -
Timothe Jahan over 8 yearsI have been late (need of full reinstall due to windows). I now run the released 4.4 kernel and I still have the same issue. I noticed that in vlc I cannot use the "overlay" mode for video, very likely due to the same issue. I also have trouble in other video program, so any help would be appreciated. Regarding the skl... file I indeed only have the ver1, not the ver4, should I do something about it ?

David Foerster over 8 yearsI'm voting to close this question as off-topic because custom kernels are off topic.
-
James over 8 yearsHow is this off-topic? It is because lack of hardware support of current Ubuntu (not +1, not non-supported) that we have to go custom kernel. It could be tagged as not "official" kernel, but shouldn't be off-topic, should it?
