我正在尝试在不同的 tty 上启动 2 个 Xorg 实例。我想在 tty1 上运行 LXDE，分辨率为 1280x800，在 tty2 上的单独 Xorg 服务器上运行 minecraft，分辨率为 640x400。这样我就可以使用 Ctrl+Alt+F1 和 Ctrl+Alt+F2 在桌面（例如互联网浏览器）和 minecraft 之间切换。这将自动切换我的屏幕分辨率。我需要以较低的分辨率运行 minecraft 以获得更好的 FPS（差异非常明显）。编辑：此方法不适用于 minecraft，当它最小化或不显示 Xorg 时它会冻结
有一个问题：当我以 rootless 方式运行 Xorg 时，我一次只能运行一个。第二个 Xorg 失败Fatal server error: (EE) no screens found(EE)。在 ~/.local/share/xorg/Xorg.1.log 中有错误：(EE) intel(0): [drm] failed to set drm interface version: Permission denied [13].这是完整日志：

我能否以某种方式在不授予 Xorg 根权限的情况下授予用户对失败的 set drm interface version 命令的权限？（例如将其添加到视频和输入组）
我的笔记本电脑是联想 G530，配备英特尔奔腾双核 T3400 1.0 至 2.16 GHz、英特尔 GM 45 集成显卡。我使用的是 Linux Void x86_64 glibc。
如果有人好奇：是的，我有一台更好的电脑，但让旧电脑正常工作对我来说很酷。
