Solved Bad video performance in FreeBSD 13.2 with Intel graphics and X11

[sukamu]

Hello,
I am having bad performance in my laptop's FreeBSD installation, after installing `drm-kmod`, xorg works but it's lagged, like it has high CPU usage (the CPU usage is normal) and the RAM usage is also normal.
Here's my Xorg.0.log http://ss.suragu.net/f/ymoi7/xorglog.txt and my the only thing in /usr/local/etc/X11/xorg.conf.d is this http://ss.suragu.net/f/8qdly/20-intel.conf

The laptop is a thinkpad x260 with a Skylake GT2 [HD Graphics 520]

What can be done to solve this issue? thanks

Is your xorg user member of the video group?

Change your driver from Intel to modesetting in your configuration file. This fixed similar issues to me on my Dell Latitude e5570.

This solved my issue, thanks!

What's "modesetting" anyways?

Checkout the man page for modesetting(). In short, instead of using the x.org Intel driver for acceleration, it uses the KMS driver exclusively (/graphics/drm-kmod)
