New PC Build - Ubuntu Not Using Intel Video Driver

[Rich_S]

Just built a new PC yesterday.
8700K 32 GB RAM 1 TB Samsung 960 Evo
Still waiting on my 1080 Ti to come in, but put everything together and installed Ubuntu 16.04 on it.


It's crawling. Like 486 slow. Windows take forever to render, there's a huge lag when typing. Etc. I'm 99% sure it's a video card issue.


Installed Intel Graphics Update Tool. Added OIBAF repos. Updated all packages. Still running ridiculously slow.


Under Additional Drivers it says it's running the proprietary microcode for Intel CPUs but nothing about video drivers.

Reinstalled, then installed 17.10 and now running 17.04. Same issue every time.

lspci says "VGA compatible controller: Intel Corporation Device 3e92" Shouldn't it say Intel 915 or HD630 or something?


Any ideas?

[Rich_S]

Think I may have found something.
If I run:

env | egrep 'INTEL|GL|MESA'
I get:
LIBGL_ALWAYS_SOFTWARE=1
Where is this getting set and how do I fix it?

[Rich_S]

That wasn't it. Unset the env variable, problem remains.

Yep.

Here is the solution for anyone that wants to run Ubuntu on CoffeeLake integrated graphics:
Make sure you're running Ubuntu 17.10 and everything is updated.

Install the latest video drivers:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update

Update the kernel parameter. I used Grub Customizer to do it:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer 
sudo apt update 
sudo apt install grub-customizer

Launch grub customizer, go to the General tab, and enter i915.alpha_support=1 under Kernel Parameters.

Reboot.

I had the same issue, this worked. Thanks!!!

Thanks for the pointers.
My problem was that the only resolution available was 1024x768.

I didn't add the oibaf repository and have successfully got 4K output by just editing /etc/default/grub, changing the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1"

Then run 'sudo update-grub'
and reboot.

BTW
Should there be a 'sudo apt-get install <something>' or 'sudo apt-get upgrade' in the Install latest video drivers section?

I can relate to the very same problem with my i7-8700k.
I updated the graphics drivers from the PPA mentioned above and added the i915.alpha_support=1 kernel boot option and now everything works fine.

Thanks!

Thank you very much. This solved my problem too!

Yes! Using the PPA and the grub switch solved my issues of the monitor not being detected, the display settings not being available, and the sound not working through HDMI. Using 8th Gen i3-8100 on Asus Prime B360-Plus mobo. Using only the grub switch hung the pc during boot.

Thank you very much.
