这是一个有点深奥的查询，但我想将 X11 显示屏从我的 Raspberry Pi 导出到仅支持 256 色的旧 Mac。就目前而言，这还不错，但 Mac 显示器上的颜色非常混乱，导致应用程序无法使用且无法识别。
是否可以将 Gnome 配置为使用不超过 16 种颜色（只是为了安全起见）？ Gnome 是否有一个主题可以用来做我想做的事情？或者，更好的是，我可以卸载 Gnome 并使用 twm 之类的东西运行 Sylpheed 之类的电子邮件客户端吗？
我在 Xorg.0.log 中收到的错误（如下所示）是：
~ $ cat /var/log/Xorg.0.log

您可以要求 X 服务器仅使用 8 位深度。在你的/etc/X11/xorg.conf文件中：
Section "Screen"
Identifier "Screen0"
DefaultDepth 8
EndSection
