**严重问题:系统有时卡死,完全无响应 **
看kernel日志,错误信息如下:

kernel BUG at /build/linux-7LGLH_/linux-4.10.0/include/linux/swapops.h:129

看上去和swap有关系,17.04默认使用swap文件,非swap分区。
搜到的信息:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674838
** 解决方法(效果待观察): **
修改fstab,改为使用swap分区
更新(2017.5.10): 换用swap分区无效。看kernel日志,似乎发生了死锁,有Intel api的字样,搜到下面的帖子:
ubuntu-15-10-and-16-04-keep-freezing-randomly
给出的解决方法为

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"
sudo update-grub
sudo reboot

以下问题通过 journalctl -b 查看启动日志中失败项

  1. nvidia驱动问题:
    安装了nvidia-375, tested驱动,但启动日志里一堆失败:
[Failed] Failed to start NVIDIA Persistence Daemon. See 'systemctl status nvidia-persistenced.service' for details.
nvidia-persistenced.service: Failed at step EXEC spawning /usr/bin/nvidia-persistenced: No such file
nvidia-persistenced[12507]: Failed to open libnvidia-cfg.so.1: libnvidia-cfg.so.1: cannot open shared object file: No such file

都是文件找不到(安装包的问题?)。用 nvidia-smi 查看状态也提示找不到 libnvidia-ml.so
手动解决方法:

sudo ln -s /usr/lib/nvidia-375/libnvidia-ml.so.1 /usr/lib/
sudo ln -s /usr/lib/nvidia-375/libnvidia-cfg.so.1 /usr/lib/
sudo ln -s /usr/lib/nvidia-375/bin/nvidia-persistenced /usr/bin
  1. 错误信息: Could not parse desktop file orca-autostart.desktop or it reference
    **原因:**因为不用屏幕朗读,所以卸载了orca。
    解决方法:
sudo rm /usr/share/gdm/greeter/autostart/orca-autostart.desktop
  1. 错误信息: spice-vdagent[1434]: Cannot access vdagent virtio channel /dev/virtio-ports/com.redhat.spice
    **原因:**桌面机,非虚拟机
    解决方法:
sudo vim /usr/share/gdm/greeter/autostart/spice-vdagent.desktop
添加:X-GNOME-Autostart-enabled=false

未理会的错误:

  1. Apparmor Init Failed, Exit Code 123
    sudo apt install apparmor-easyprof-ubuntu
  2. AppArmor parser error for /etc/apparmor.d/usr.bin.firefox. line 23: Could not open 'abstractions/ubuntu-browsers.d/firefox'
    sudo systemctl status -l apparmor.service
