Problems and Solutions for sudden failure of the left mouse button of centos

Environment: CentOS 6.5, Kernel Linux 2.6.39-400.214.4.el6uek.x86 _ 64, GNOME 2.28.2

Background: Installation of python-psutil-0.6.1-1.el6.X86_64 and glances-1.7.4-1.el6.noarch in April 10

One day later, the system found that the left mouse button would change to the right mouse from time to time. After a second or two, the left mouse button failed (right-click and scroll wheel are normal), and no GNOME Panel component could be clicked.

When the problem was found, I tried to fix it. When the problem occurred, I used Ctrl + Alt + F2 to enter the TTF2 interface and log on as the root user. I found that the terminal had output several error statements, similar: iwlagn :05:00. 0: Aggregation not enabled for tid 0 because load = 7

A solution http://xiaoxia.org/2012/04/07/linux-intel-1000-bgn-n-mode-bug/ found online

After the instruction is completed, the problem persists and is not resolved. At the same time, due to possible wireless problems, the hardware wireless switch is disabled and problems still occur.

I had to look for other solutions, because I/O read and write temporarily occurred when the problem occurred, so I used the top tool to monitor the system.

Top-B

No exceptions were found, so I had to find a solution.

If you suspect the GNOME problem, switch to KDE and find that there is no similar problem in KDE. Therefore, reinstall GNOME.

Yum reinstall gnome *
