Fedora18 crashes frequently and tries to solve the problem

Fedora18 crashes frequently and becomes very popular after a while, with no response from the mouse or keyboard. In win7, the heat is good and rarely crashes.

Now delete Firefox and change chrome to change KDE

Yum groupinstall KDE-Desktop

Installation instructions:

Yum install kde-i18n-Chinese.noarch

Yum install kde-l10n-Chinese.noarch

Then, log out. There is an option under login. Select KDE,

Enter the account password and log on to the KDE.

Check whether the problem can be solved.

This method is better. It took a day not to die. When you open the Google browser and open multiple pages to watch videos at the same time, the heat sink will soon become hot. Try to disable the independent video card. The command is as follows:

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

View the closing result after closing

CAT/sys/kernel/debug/vgaswitcheroo/switch: 0: IgD: +: PWR: 0000: 00: 02.01: DIS: off: 0000: 01: 00.0 proves that the Singleton is successfully disabled.

Add the following command to the end of/etc/bashrc and restart the computer.

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

Let's take a look at the effect. Computer crashes. There are many issues with fedora.

The system prompts that you do not have the permission to run the video, but the independent video card is disabled.

I just crashed again. Normal Internet access, suddenly fan flying, feel bad hurry to reboot, and then the machine will crash, the fan is still flying, hot, can only hard shutdown, distressed computer. View/var/log/message

The above is an error.

I. Bluetooth Problems

Usage [544]: [system] activation via systemd failed for unit 'memory-org. bluez. Service'

Foreigners said this solution, refer to https://bbs.archlinux.org/viewtopic.php? Id = 155714

1. First check the Bluetooth status

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

2. Unable to detect the Bluetooth status. Therefore, the Bluetooth status can be detected.

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

3. view the setting result

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

2. solve this problem

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.

1. Check

[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. See the mdmonitor-takeover.service and remove it

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

First. Continue the test. Download both centos and ubuntu. Fedora then changes the system. It's a waste of time.
