I've got a new laptop with an i7-6700HQ, a nvidia gtx 960m and a 256gb pci ssd and everything works perfectly fine when I'm using the nvidia card. However when I'm using the intel card the system crashes constantly. Whenever I start steam, suspend the computer, reboot, shutdown, turn off the screen or close the lid the systems freezes and I am unable to do anything. I can't even access tty1.
I think this is due to the intel graphics card. I got the following error upon initramfs rebuilds (
sudo update-initramfs -u -k all)
update-initramfs: Generating /boot/initrd.img-4.4.0-38-generic W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1.bin for module i915_bpo W: Possible missing firmware /lib/firmware/i915/skl_guc_ver6.bin for module i915_bpo update-initramfs: Generating /boot/initrd.img-4.4.0-21-generic
I fixed that by installing the missing firmware from here but the problem persists.
Edit: I reinstalled my entire OS and replaced above error with the actual error I got. I reinstalled nvidia-367 and nvidia-prime. The problem persists.....
Does anyone have any suggestions on how to troubleshoot this problem??
Edit 2: I reinstalled again and I managed to fix it. I reinstalled without swap (it kept asking for a password for cryptswap and caused some of the freezes) I installed the nvidia drivers with gdm3 and added the usual nouveau.modeset=0 to grub all from tty1. I edited /etc/modprobe.d/blacklist.conf after a reboot to blacklist nouveau. I downloaded the i915 firmware packages and installed them.
After I did that last step everything started to work perfectly.
Edit 3: I executed all updates and it stopped working again...... At least I now know that its an update that caused it.....
It's the gnome session that crashes. it appears to be a know bug
I'm reinstalling AGAIN. Some update broke everything and I can't fix it...
Edit ∞: I think I finally managed to fix it....I hope.....
I started by installing ubuntu gnome 16.04 without swap. After installation I rebooted and had to shut down the system by holding alt+prtscn/sysRq+b.
After booting I enter tty1 (ctrlaltf1) and updated the kernel to version 4.7.2 (guide) and rebooted.
I installed nvidia-367 and prime with the lightdm desktop manager (rip nice looking login screen) and rebooted.
I switched to the intel gpu and rebooted.
I logged in and downloaded this. I executed the installation commands needed.
sudo dpkg -i intel-grapics-update-tool_2.0.2_amd64.deb sudo apt-get -f install wget -q0 - https://download.01.org/gfx/RPM-GPG-KEY-ilg-r | sudo apt-key add -
The last line adds the key so the update manager trusts the repository. I started the installed program (super, intel and clicking the intel logo) and let it do its thing. (This is the step that adds the repository that needs that key.)
sudo apt-get update | sudo apt-get upgrade and rebooted.
This was the step that always failed. logging in after installing the updates. This time however it worked.
I'll keep this edit here until i'm certain that the system is stable. If it is I'll add it as an answer.
Edit ∞+1: the system hangs on shutdown and reboot with intel graphics. I am attempting to fix this
Edit ∞²: I found the reason why my system hangs on shutdown. It's due to the intel graphics drivers.....So I decided to temporarily kill them with the
nomodeset parameter in grub (well...until X is loaded that is). Everything works fine now....except secondary displays (and steam (an X error occurred) but this can be fixed by editing this). I am even able to use the intel graphics card (2600 fps glxgears!!!whooo!!). I have since restored the beautiful gdm3 login and am currently adding an extra item to the grub2 list that allows me to quickly switch between intel and nvidia.
