Ubuntu
登錄桌面時黑屏
在Kubuntu 15.10上，我通過顯示管理器登錄時收到黑屏。我可以使用 Ctrl-Alt-F6 登錄到文本控制台並查看我的文件，但即使在那種環境中，當我鍵入時
startx螢幕也只是一片空白，沒有任何進一步的反應。我已將~/.kde目錄重命名為，~/.kde-old但問題仍然存在。顯示管理器有一個設置“故障安全”，當我嘗試使用它設置登錄時，我只是在幾秒鐘後再次啟動回到顯示管理器螢幕。
這是 dmesg，我在下面粘貼了我認為的相關行，但點擊連結會將您帶到儲存整個日誌的 Pastebin。

**編輯：**我剛剛創建了一個新使用者
test，它也會從假定的故障安全登錄模式中啟動。但是，該使用者可以正常登錄其桌面。因此問題似乎出在我使用者的配置文件中。我現在正在將它們一分為二，但我仍然對想法持開放態度。謝謝你。
問題似乎出在
