fedora18频繁死机,尝试解解决

Fedora18 频繁死机,开一会就特别热,鼠标键盘都无响应。在WIN7下散热良好,极少出现死机情况。

现在删除firefox 更换Chrome  更换KDE

 yum groupinstall kde-desktop

    安装中文:

    yum install kde-i18n-Chinese.noarch

    yum install kde-l10n-Chinese.noarch

    然后注销,登陆的时候底下有选项,选择KDE,

    输入账号密码,登陆就切换到KDE了

看看能不能解决。


这个方法好了一些。用了一天没死。打开google浏览器的时候,同时开多个页面看视频,散热口很快变烫。尝试关闭独立显卡。命令如下

echo IGD > /sys/kernel/debug/vgaswitcheroo/switch

echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
关闭后查看关闭结果

cat /sys/kernel/debug/vgaswitcheroo/switch

如果显示如下:

0:IGD:+:Pwr:0000:00:02.0

1:DIS: :Off:0000:01:00.0

证明独显关闭成功。

将以下命令添加到/etc/bashrc结尾处,重启电脑

#todo: wulong close graphics card
echo IGD >/sys/kernel/debug/vgaswitcheroo/switch ;echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
#endif

再用一阵,看看效果。总是热得电脑死机. fedora的问题还真多。

重启运行提示没有运行权限,但是独立显卡确实关掉了。


刚才又死机了。正常上网,忽然风扇飞转,感觉不好赶快reboot,然后就死机,风扇仍然飞转,热得烫手,只能硬关机,心疼电脑。查看/var/log/message

上面就是错误

一.蓝牙问题

dbus[544]: [system] Activation via systemd failed for unit 'dbus-org.bluez.service'

老外说这样解决,参考https://bbs.archlinux.org/viewtopic.php?id=155714

1.首先查一下蓝牙状态

[root@localhost wulong]# systemctl status dbus-org.bluez.service
dbus-org.bluez.service
   Loaded: error (Reason: No such file or directory)
   Active: inactive (dead)

2.无法检测蓝牙状态,那么允许检测蓝牙状态

[root@localhost wulong]# systemctl enable bluetooth.service
Failed to issue method call: File exists


3.查看设置结果

[root@localhost wulong]# systemctl status dbus-org.bluez.service
bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled)
   Active: inactive (dead)

二.解决这个问题

May 27 23:53:59 localhost systemd[1]: Cannot add dependency job for unit mdmonitor-takeover.service, ignoring: Unit mdmonitor-takeover.service failed to load: No such file or directory. See system logs and 'systemctl status mdmonitor-takeover.service' for details.

参考这里

https://bugzilla.redhat.com/show_bug.cgi?id=901651

1.查看一下

[root@localhost log]# ls /etc/systemd/system/sysinit.target.wants/
lvm2-monitor.service  mdmonitor-takeover.service


[root@localhost log]# ls -l /etc/systemd/system/sysinit.target.wants/mdmonitor-takeover.service 
lrwxrwxrwx. 1 root root 46 May 23 05:23 /etc/systemd/system/sysinit.target.wants/mdmonitor-takeover.service -> /lib/systemd/system/mdmonitor-takeover.service


2.看到mdmonitor-takeover.service,把它移除

[root@localhost log]# rm /etc/systemd/system/sysinit.target.wants/mdmonitor-takeover.service

先这样。继续测试。把centos  和ubuntu都下载下来。fedora再这样就换系统。小白鼠不好当,太浪费时间了。
