從今天開始，我遇到了一個問題：我的滑鼠（僅）每分鐘凍結兩次或三次，持續 2-3 秒。我不確定這是否是巧合，但自從我安裝 VirtualBox 以來就已經開始了。之前我可以透過將滑鼠插入另一個USB連接埠來解決這個問題，但現在問題又出現了。每次當我的滑鼠掛起時，我都會得到一個新的 USB 識別 (dmesg)：

答案1
這很可能是 VirtualBox 整合模組為來賓作業系統提供主機 USB 端口，但無法正常工作。
試著告訴 VirtualBox 讓主機 USB 連接埠保持獨立。
答案2
同時我也不認為這是 VirtualBox 的問題。因為今天我切換到Ubuntu Maverick，問題仍然存在。當我換了一隻滑鼠後，這個問題突然消失了。即使我重新安裝 Virtualbox 並運行映像，也沒有出現任何滑鼠延遲現象。我會說這是一個滑鼠問題，但它並不能解釋為什麼瀏覽器在我執行時以恆定的間隔凍結（就像滑鼠指標一樣）qemu-img convert -O raw myfile.vhd myfile.bin。而且我還沒有重新安裝qemu，因為我現在不需要它，所以也許qemu仍然對系統做了一些「特殊」的事情。此外，它並沒有解釋為什麼舊滑鼠可以與我的 Ubuntu 筆記本一起使用。但好吧，我現在就這樣吧，因為目前它有效。
