當我進入 Ubuntu 12.04 的開始功能表時，我無法使用自己的帳戶啟動，也沒有看到任何錯誤訊息。
我嘗試使用我的帳戶，然後返回原來的開始功能表。我可以以訪客帳戶啟動，但隨後我無法使用我自己的文件。另外，在訪客帳戶中，我沒有任何權利更改自己的帳戶。
我該如何修復它？
Ctrl我可以使用+ Alt+進入終端F1。
我在更新管理器程式中安裝更新後開始出現問題，但我不記得更新了哪些更新。
在此之前，我也遇到過啟動終端的問題。我看到終端機視窗在螢幕上閃爍，然後消失了。無論我嘗試使用哪個終端。
我有一台Dell Inspiron N7010，Intel(R) HD 顯示卡，基於x64 的PC，Intel Pentium CPU P6100，2.00 GHz，1999 MHz，2 核2 邏輯處理器BIOS Dell A11 2011 年3 月31 日，SMIOSB 2.6 Mem Gb，全虛擬記憶體 7.6 GB
我在啟動畫面中看到的 Ubuntu / Linux 版本是：
GNU-GRUB version 1.99-21ubuntu3
在右下角寫著：
debian The Universal Operating System.
版本是：
- Ubuntu，使用 Linux 3.2.0-24-generic-pae Ubuntu，使用 Linux 3.2.0-24-generic-pae（復原模式）
- 記憶體測試（memtest 86+）
- 記憶體測試（memtest 86+，序列控制台115200）
- Windows 7（載入程式）（位於 /dev/sda2）
- Ubuntu，使用 Linux 2.6.38-10-generic（在 /dev/sda5 上）
- Ubuntu，使用 Linux 2.6.38-10-generic（復原模式）（位於 /dev/sda5）
- Ubuntu，搭配 Linux 2.6.38-8-generic（位於 /dev/sda5）
- Ubuntu，使用 Linux 2.6.38-8-generic（復原模式）（位於 /dev/sda5）
2.6.38-10 和 2.6.38-8 版本都可以工作，但在這些版本中我無法存取我自己的檔案。

剛才我從 Ubuntu 收到了很多新軟體，因此（我認為）我現在能夠在 Ubuntu 12.04 中使用我的用戶帳戶。
我就放心了！
唯一仍然無法正常運作的是啟動 GUI 終端，例如 Byobu 或其他終端。我只看到螢幕上快速閃爍，然後就消失了。
為了回答您嘗試該less etc.命令的建議，我收到以下訊息：
/usr/sbin/lightdm-session: 27: .:Can't open /usr/bin/byobu-launch
/home/rita/.xsession-errors (END)
僅此而已。
也許我丟失了一些文件或包或其他。我在整個文件系統中搜尋了該文件，但不幸的是，它不在那裡。不知道為什麼。

希望我的網路連線能夠保持足夠長的時間以獲取新資訊：我再次執行該less etc.命令並獲得以下資訊：

/home/rita/.xsession-errors
答案1
嘗試看看您是否可以/home/replacethiswithyourusername/.xsession-errors從文字控制台讀取（您似乎稱之為“終端模式”）。您可以使用該less應用程式讀取該檔案：
less /home/replacethiswithyourusername/.xsession-errors
PageUp使用遊標鍵和/或、PageDown、Home、瀏覽文件文字End。按Q退出“less”應用程式並返回 shell 提示字元。
它可能包含有關 GUI 會話無法啟動的原因的相關資訊。
此外，在「圖形問候語」（您通常使用使用者名稱和密碼進行身份驗證以進入 GUI 會話的圖形介面）中，應該有一個選項可以選擇不同的「登入工作階段」。
它可以列出諸如“Ubuntu Classic”或名稱中帶有“Unity”的選項之類的內容。
在使用您的使用者名稱和密碼進行身份驗證之前，請嘗試選擇不同的選項。其中之一可能會起作用......
