Ubuntu
Ubuntu 14.04.1、14.10 基本發行版需要 30 分鐘以上才能進入啟動畫面
更新：我找到了一個臨時的解決方法，但我仍然想找到一個更永久的解決方案。
解決方法：
- 我在卸下筆記型電腦電池的情況下開始啟動過程。如果我這樣做，它會在正常的時間內啟動到加密密碼提示（我不是指使用者登錄螢幕）——大約 5 秒（相對於 30 分鐘以上）。
- 接下來，我必須在輸入加密密碼解鎖分區之前重新連接電池，否則它將無法啟動其餘的方式。（它將進入命令提示符，我將不得不重新啟動。）
因此，目前，除了每次啟動筆記型電腦時都必須忍受上述情況之外，它工作得很好。
我的筆記型電腦大約有 6-7 年的歷史，電池也是如此。電池僅可容納大約 2% 的“充滿電”。那麼，也許電池在初始啟動過程中導致錯誤？
Update2： 我能找到的唯一與這個問題有關的是這個論壇主題： http ://www.tomsguide.com/forum/49975-35-typing-keyboard-slow
使用者正在執行 windows，但它仍然非常相似。在使用 Linux 的作業系統中，壞電池的表現似乎有所不同。
原帖：
我將非常冗長並提供我所知道的所有資訊，如果我需要提供其他任何資訊，請告訴我。
過去兩天我一直在Google上搜尋，但我找不到任何與此類問題完全相同的幫助論壇文章，更不用說補救措施了。
症狀/問題：
- 引導過程將需要正常的時間才能進入 grub 菜單。
- 然後，一旦選擇了 Linux 發行版（任何發行版，請參閱下面我嘗試過的所有發行版的文本），它會載入一個黑屏，除了閃爍的下劃線游標外，它是空白的。
- 它在上面的螢幕上停留了 30 多分鐘，完全沒有變化。在這個螢幕上，任何時候都不會列印任何資訊。
- 接下來，它突然顯示發行版啟動畫面，從這一點開始，一切都正常執行。
簡短的硬體描述：
- 底部提供更詳細的資訊
- 網關筆記型電腦
- M系列
- 型號：M-7327u
- 處理器：英特爾奔騰
- 記憶體：3GB
- 1 個硬碟 250 GB
發行版：
都顯示相同的啟動問題
- 我嘗試從 USB 啟動到實時會話的發行版：
- 魯邦圖 14.04.1 amd64
- xubuntu 14.04.1 amd64
- ubuntu 伴侶 14.04.1 amd64
- ubuntu 伴侶 14.10 amd64
- Linux Mint 17.1 amd64
- Elementary OS Luna amd64 - 我用來設置原始（預發行）安裝的相同版本/iso
- Gparted - 現場直播
- 我安裝的發行版（全部 64 位）：
- ubuntu 伴侶 14.04.1
- Linux Mint 17.1
歷史（問題開始之前）：
我安裝了 Windows 7 和 Elementary OS Luna Duel。在過去的 3 個月裡，這一切都很好。我決定刪除 Windows 並從基本作業系統切換到更易於定制的發行版。
此外，在我安裝新發行版的前幾天，elementary 在暫停後開始需要很長時間才能恢復。雖然我沒有任何問題啟動。啟動大約需要 1 分鐘或更短的時間。
到目前為止我嘗試過的 - 事件序列：
注意：每次我嘗試從此時啟動到 linux 發行版時，啟動都會顯示上述症狀。
- 首先，我嘗試在側窗 7 上安裝 ubuntu-mate 14.04.1。啟動到實時會話大約需要 30 分鐘，但我還是安裝了。安裝按預期進行，並且在正常時間。引導到新安裝需要 30 多分鐘。我嘗試重新啟動以查看這是否只是初始啟動的問題，不。第二次啟動也花了 30 多分鐘。
- 接下來，我從這個論壇（http://bit.ly/1yhcSEM）嘗試了這些技巧，但都沒有幫助：
- 移除所有 USB 設備
- 在 BIOS 中禁用 USB 遺留（我沒有嘗試更新我的 BIOS，考慮到目前版本與原始基本安裝配合得很好，我認為不值得冒險。）
- 接下來，我嘗試啟動以下發行版的實時會話，都顯示相同的啟動問題：我嘗試的發行版（全部 64 位）從 USB 啟動到實時會話：
- 魯邦圖 14.04.1
- 會員 14.04.1
- ubuntu 伴侶 14.04.1
- Ubuntu 伴侶 14.10
- Linux Mint 17.1
- Elementary OS Luna - 我用來設置原始（預發行）安裝的相同版本/iso。
- 接下來，我想我會完全從頭開始，所以，從現場會話（從 USB 啟動）我用以下命令將硬碟歸零：
$ sudo dd if=/dev/zero of=/dev/sda bs=512然後使用 gparted 我給了它一個新的 msdos 分區表（預設） 5. 接下來，我通過從 USB 引導的實時會話安裝了 Linux Mint 17.1。實時會話有同樣的啟動問題，耗時 30 多分鐘。
安裝過程很順利，花費了正常的時間。不到30分鐘。重新啟動後，重新啟動到新安裝時顯示相同的問題。我嘗試重新啟動，這次在 bios 菜單中關閉了 USB legacy。同樣的啟動問題。 6. 接下來，我從 USB 啟動 gparted live os。起初它正常啟動，並且在合理的時間內啟動，但是在設置了初始設置（鍵盤資訊、語言等）之後，當它實際啟動到作業系統時，它也遇到了同樣的問題。
在現場執行 gparted 時，我嘗試了以下操作：
從終端我嘗試在所有分區上使用 fsck $ sudo fsck /dev/sda 但它似乎沒有做任何事情。它給出了以下輸出：來自 util-linux 2.25.1 的 fsck
7-接下來，我嘗試使用引導圖。最終導致 bootchart gui 生成圖像的數據過多。其中一個日誌文件是 68MB。如果有人可以推荐一種我可以共享 bootchart tarball 或解壓縮文本文件的方法，我會分享它們。但是，它們太大了，我無法想像有人會想看透它們。

根據實驗和一些資訊，我能夠收集到：如果您遇到上述症狀，並且您使用的舊筆記型電腦的電池接近耗盡，那麼基本上您的電池已經達到了對您的系統實際上有毒的程度。
我在 update1 中發布的解決方法可能對您有用。但是，如果你有硬幣，你應該繼續更換電池。或者，如果你真的很潮，就買一台新的筆記型電腦，用舊的筆記型電腦作為學習/測試伺服器，直到它最終死掉。
