有时候电脑挂起后没有登录界面, 只剩下一张蜥蜴的壁纸和鼠标. 可以开控制台.
我记得在 Ubuntu 里面可以通过
killall gnome-session
来重新登录.
KDE 肿么办? 或者有更高明的解决方案能解决这个问题吗?
不知道发在哪里, 只能发在水区了…
刚才吃饭去了, 又出现了这种情况 
之后我又重启了一次.tty1 上面有一堆文字, 但无法复制贴上来…
tty 中能登录不呢？不能复制就拍照试试
貌似挂起在很多电脑上都出现了问题。不知道你是挂起到内存还是挂起到磁盘？
最直接的方法是 kill 掉 Xorg。那样就会重现到登陆界面了。
这个问题我感觉不太好。
我从来不挂起。
看 /var/log/messages 卡在哪儿。
今天又出现了另外一个问题, 自从上次后我一般就直接注销了, 这次经过了一晚上的注销, 登录后卡在蜥蜴壁纸界面, 无法开 tty. 我装了 Bumblebee 跟这个可能有关系吗?
上次是挂起到内存
这是2月7日,我两次发帖时间中间的信息1:07-1:39

sudo cat /var/log/messages|grep 2014-02-0[789] > mess
大大们自行 grep
这次又出现了第一种情况,
killall Xorg
后解决问题!终于能够登录了.

这是说你的一个 ID 为 00:07 的 PNP （Plug & Play）设备没能成功 resume。你可以用：
$ dmidecode
$ lspci
$ lsusb
看看是哪个设备。然后拔下该设备（比如是个 USB 的鼠标、耳机、打印机什么的）再试。

这个据说是 ACPI 的一个 bug。具体看这里：https://bbs.archlinux.org/viewtopic.php?pid=1341777

可以试着先 sudo systemctl stop NetworkManager.service 后再挂起看看有没有效果。如果问题依旧，就不是 NetworkManager 的问题。我觉得是它的概率比较低。
我的硬盘今天好像挂掉了，导致无法启动系统。现在准备去换一块。为什么那个设备是可拔插的 PNP？我好像没有使用任何可拔插的设备，这几天都是裸机运行。有没有可能是硬盘的问题导致无法启动？
按照 czmmiao.iteye.com/blog/1058215 ，使用 SMART 检测硬盘：
# smartctl -H /dev/sda
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.11.6-4-desktop] (SUSE RPM)

目前开机无法启动，不过似乎有时候能进控制台，等我看看 00:07 是不是硬盘。
请问我的硬盘还有的救吗？如果没得救，准备这两天去换一块硬盘 
至于 su 姐所说 Network Manager 的问题，我家的路由器好像只提供 IPV4 不提供 IPV6 的连接，所以在图形界面看到 IPV6 就是未分配。我怀疑这个应该是不用担心的。
显卡是什么型号的？
我以前也出过这个问题，当时的显卡是 nvidia 的。
显卡是 NVIDIA GT630M
我还遇到过锁屏（出现登陆框和密码框）的时候……竟然鼠标晃一下就能开 完全不用输入账户、密码，竟被人嘲笑说：你这是故意 P 的一张图做待机背景么
因为那就是待机不是锁屏。不信你查查 KDE 设置绝对没有默认设置说多长时间没用就锁屏
电脑修好后重装好了系统以及 Bumblebee 后又有两次不出现登录界面的。
最新进展是，应该可以排除是 Bumblebee 的问题，也可以排除是硬件的问题。因为我有一个同学她的电脑是 AMD 的显卡，也出现了这个问题。她用的是开源驱动 Radeon 。所以这会不会是 openSUSE 的问题呢。
