Ubuntu 的稳定性远不及主流操作系统。我的系统挂起主要是因为 Firefox 打开 Issuu 或 html5 网站等页面时出现这种情况，但并非唯一原因。安装它时，我没想到我的电脑会如此频繁地挂起。我的问题是，Ubuntu 一直不稳定吗？普通用户多久会遇到一次系统挂起，完全无法从Ctrl+ Alt+{ Backspace/ F2/ F7/ T} 中获得任何东西？
我的视频驱动程序u@laptop:~$ lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller:
Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
Subsystem: Acer Incorporated [ALI] Device 0573
Kernel driver in use: i915
再举一个例子，重启后，当我展开反汇编项目时，“错误报告”本身的用户界面就冻结了。幸运的是，这并没有冻结操作系统。
另一个导致操作系统冻结的原因是当我连接 iPhone 时。任务栏上会弹出两个或三个黑色电话图标（显然它会自动连接两次）。如果我没有在两次连接上都按取消键，操作系统就会挂起。当我离开其中一个弹出窗口并稍后返回时（只需将鼠标悬停在任务栏上），操作系统就会冻结。这相当戏剧性。我几乎会认为一些 MS 破坏者加入了 Ubuntu 开发团队。
这是崩溃的部分系统日志。我没有记录内存使用情况。也许有帮助？这个问题已经关闭，没有人可以回答了吗？我认为末尾的 \00 是我对计算机的硬重置。还是真的？
