Dears, Eu instalei o kernel 4.4 rc7 no meu Ubuntu 15.10 seguindo esta página github.com/awesomebytes/ubuntu14_dell_xps13_9350 apenas substituindo o código para o rc6 pelo código do rc7.
ao instalar recebi uma mensagem de erro de que o i915 não foi encontrado, pois parece estar ligado à aceleração 3D, estou um pouco preocupado que estou perdendo algum desempenho. O que posso / devo fazer?
de acordo com o primeiro comentário Eu instalei o rc8, eu ainda usei o mesmo script de instalação como no link acima.
Aqui está a saída

now you can reboot (maybe you'll need to do it twice).
Parece que o i915 está no final do script nesta parte
sudo bash -c "echo 'i915
nvme' >> /etc/initramfs-tools/modules"
sudo update-initramfs -u -k all
Também produz alguns problemas antes, mas o que parece ser menos preocupante (o DKMS é o driver para o dongle usb wifi que eu não preciso mais).
Thx, Timothé
Eu poderia resolver o erro, baixando o módulo ausente aqui: link
Infelizmente, duvido que isso resolva tudo, reproduza o vídeo no VLC com aceleração gráfica (modo de sobreposição), ainda não consigo redimensionar o vídeo, mas vou abrir uma solicitação separada para isso.

Substitui o curl pelo wget e isso funcionou perfeitamente em relação a 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
