我在 2017 年 Dell XPS 13 上运行 EndeavourOS (Arch)。内核 5.7.2-arch1-1 [硬件名称：Dell Inc. XPS 13 9360/02PG84，BIOS 2.13.0 11/14/2019]
我的办公桌上有一个多显示器设置，工作时有以下配置：
兰德尔：
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 290mm x 170mm
1920x1080 59.93*+ 59.93
DP1 disconnected (normal left inverted right x axis y axis)
DP1-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm
3840x2160 60.00 + 30.00 25.00 24.00* 29.97 23.98 29.98
DP1-2 connected 1440x2560+5760+0 left (normal left inverted right x axis y axis) 520mm x 300mm
2560x1440 59.95*+
我已经删除了不活动的行以保持简短（呃）。
DP1-1 和 DP 1-2 通过无源 Thunderbolt 连接至双显示端口适配器。
重新启动时（不是短暂重新启动），不会检测到显示器，我发现操作系统检测它们的唯一方法是在显示器或适配器上的显示端口插座上拔下它们，然后将它们重新插入逐个。在 Thunderbolt/USBC 端口拔出适配器不会导致显示器工作，甚至不会出现在 xrandr 输出中（在 Thunderbolt 端口拔出并重新添加适配器后的日志输出）。
有没有办法让这些监视器在重新启动时始终被检测到，或者失败 - 有一种方法“震动”操作系统来检测它们？
lspic以下是重新journalctl插入每个显示器后的输出。
我从启动时检查了日志，没有发现任何看起来（在我看来）像系统在尝试检测监视器时失败的东西。
任何帮助表示赞赏。
