Catch it too. U had too modern Intel chip :slight_smile: Use modesetting driver instead intel (look: https://wiki.gentoo.org/wiki/Intel#xorg.conf_2).

Before proceeding with the Intel DDX driver , note that this driver has been slowly deprecating for several years. This has caused other major[4][5] Linux distributions to begin to move toward the modesetting DDX driver (detailed in the section below). Although presently faster than modesetting driver , there has been no official package release from Intel upstream for their DDX driver for quite some time[6], and is therefore causing a maintenance burden on Gentooā€™s X11 package maintainers.

With this being stated, the Intel DDX driver has slight speed advantages over the generic modesetting driver as it is able to more closely interact with hardware acceleration present in chips utilizing SNA and DRI3.

So you need change section ā€œDeviceā€ in /etc/X11/xorg.conf similar way:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "DRI"            "3"
