每天晚上下班时，我都会通过右上角面板上的 ubuntu“电源”按钮锁定屏幕。
早上上班时，我会看到登录屏幕。这种情况不是每天晚上都会发生，但大多数时候都会发生。
我在戴尔 Inspiron 上运行 ubuntu 10.04。我已添加了一些硬件规格以及 dmesg 输出。请告诉我还有哪些其他日志可能有用。
谢谢！Corey

答案1
@msw：这似乎不是同一个错误。我没有遇到冻结或锁定的情况。我不需要重新启动或关闭我的机器。
@Tim：我唯一可用的电源设置是“让显示器在 XX 分钟内进入睡眠状态”。我已将其完全禁用，并且它已经连续两个晚上没有让我退出。也许让显示器进入睡眠状态会导致 xorg 崩溃。如果我再次看到该错误出现，我会报告。
