I have got a laptop Lenovo Yoga 910. After i try hard to install Ubuntu with Win10, i find that the screen flickers in Ubuntu16.04. I also have tried Ubuntu14.04, the screen is normal.

The VGA controller is

VGA compatible controller: Intel Corporation Device 5916 (rev 02)

The graphics card is Intel graphics 620. I have tried COMMAND xrandr to change the resolution. it doesn't work. If I change the resolution to 1600*900, it's OK. If I change the resolution to 1920*1080, the screen will flicker.

Does anyone meet the same problem? And are there any effective solutions?

According to Mangled and flickering graphics on Yoga 910 with 1920x1080 resolution, you need to add i915.enable_rc6=0 to /etc/default/grub's line 11, or GRUB_CMDLINE_LINUX_DEFAULT.

  • That solution "works" to stop the screen flickering, but it causes the fan to be always on, with periods of excessively high fan noise. I'm going to post a question about the fan issue -- as I don't see one specific to that issue. – Rsync Aug 13 '17 at 16:41

same issue here, solved by rolling back the kernel. now I'm on 4.10.0-041000-generic and the issue is gone. Hope this helps!
