Intel Graphics – Get Native Screen Resolution with Intel Z370 Express Chipset

17.10intel graphics

I assembled a new computer with the following configuration.

  • Intel i7 8700K
  • Gigabyte Z370M D3H motherboard (Intel Z370 express chipset)

When I boot windows, I am getting a native resolution of 1920X1080. But in ubuntu, I am getting only 1024X768. I am using an Acer monitor connected via VGA using a HDMI VGA converter.

I have tried all possible solutions discussed online, with xrandr etc. But no luck so far. xrandr is detecting the display as just default.

I am running Ubuntu 17.07 with kernel 4.13.0.

Any idea how to proceed with this?

According to a review by Phoronix of Intel UHD Graphics 630 on Linux a kernel 4.13 or newer and the kernel commandline switch i915.alpha_support=1 are required to enable the graphics drivers.

According to Phoronix: "That will change with the Linux 4.15 kernel where Coffeelake/UHD Graphics are enabled unconditionally."

However, on a PC with an ASUS ROG Strix Z370-E Gaming mainboard and Intel Core i5-8400 CPU Linux kernel 4.13 from linux-image-4.13.0-16-generic in conjunction with i915.alpha_support=1 did not help. Installing a Linux kernel 4.15 rc6 from http://kernel.ubuntu.com/~kernel-ppa/mainline/ provided the high screen resolutions.

(We haven't tried other kernels.)
