Setup

Screen

The Pocket 3’s display is designed for portrait devices and is rotated by 90 degrees counter-clockwise by default.
GPD Pocket 3 的屏幕总成用的是平板电脑的库存屏幕，默认的固件是竖屏模式,可以通过下面的命令修改屏幕的模式。

~# xrandr --rotate right

可以添加到配置文件 /etc/X11/xorg.conf.d/01-monitor.conf

+ Section "Monitor"
+   Identifier "DSI-1"
+   Option "Rotate" "right"
+ EndSection

Note: The Identifier may be different depending on your display driver of choice (either DSI-1 for modesetting or DSI1 for xf86-video-intel)

Install intel video drivers

~# pacman -S xf86-video-intel

/etc/X11/xorg.conf.d/20-intel.conf

安装后 Identifier 将 /etc/X11/xorg.conf.d/01-monitor.conf 中的 DSI-1 改为 DSI1

Section "Monitor"
-   Identifier "DSI-1"
+   Identifier "DSI1"
    Option "Rotate" "right"
EndSection

屏幕缩放

由于屏幕分辨率较高，所以 UI 元素较小，需要调整 DPI 来缩放屏幕。

~/.Xresources

Xft.dpi: 144

如果需要支持多显示器可以设置一下：

Section "Monitor"
    Identifier  "DSI1"
    Option      "Rotate"        "right"
    Option      "Primary"       "true"
