我有一台 HP Pavilion Power 15-CB030NL，運行 Debian 10，核心 4.19.0-9-amd64。
以下是我的 2 個 GPU：
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 630 (rev 04) (prog-if 00 [VGA controller])

即使安裝了 nvidia 驅動程式並使用 bumblebee 在整合英特爾和專用 nvidia 之間切換，我也不知道如何讓 HDMI 在這台筆記型電腦上運作。然而，我開始使用 type-c 連接埠（帶有 hdmi 適配器），一切都正常工作。有一天，當我使用外接顯示器時，筆記型電腦突然變黑，而且 type-c 連接埠也停止工作！
我將在這裡粘貼一些有趣的輸出：

在 # tail -f /var/log/kern.log 上，如果我從 type-c 連接埠插入或刪除任何內容，則不會發生任何情況。

我還使用了外部華碩 ZenScreen MB16ACM 顯示器，它工作正常（因此只需使用 type-c 到 type-c 電纜，無需任何適配器）。現在，當我將其連接到筆記型電腦時，電源燈亮起，但它沒有「看到」它。我還嘗試了一個 type-c 轉 USB 適配器（帶有一個簡單的 USB 外部驅動程式），但 debian 根本沒有檢測到它。
我想知道是否應該在內核中啟用 CONFIG_TYPEC_DP_ALTMODE（CONFIG_TYPEC_DP_ALTMODE=m），但我不知道如何做到這一點。
更新
我發現如果我打開網路攝影機或使用 VMWare 進行虛擬化，type-c 連接埠就會停止工作。它會在一段時間後發生，例如 10-15 分鐘。我開始認為這與“省電”問題有關，但我停用了所有有關省電的設置，並且電源線始終打開。所以電腦也沒有電池電量不足。
