Notebook installation centos6.4 What toss

Landlord since the installation of Linux last year, the notebook will ring up.

Landlord Analysis reasons:

1. The first installation is completely installed, the landlord thought the system installed too much software, insufficient resources. Ignore, continue to think, continue to fever. (This time the landlord did not know the top command)

2. Then the landlord installed to the minimum desktop installation, thought this will not ring, will not heat. The result is still. Looking for Niang said: graphics problems. There are power management issues, fan issues, hard drive problems.

Landlord began to toss, first said video card problem:

The landlord with the ATI graphics card, hd5650, downloaded from the official website after installation, the notebook resolution changed, the brightness changed to the brightest. Different dimming. Do not know how to solve, so uninstall. Restored to the original.

Landlord then toss:

Notebook Laptop-mode-tool Power Management

Install Laptop-mode-tool separately

This is not configured well, and the failure ends.

Fancontrol http://ubuntuforums.org/showthread.php?t=42737

This is not configured well, and the failure ends.

Hddtemp Yum install hddtemp view hard drive temperature

Hddtemp view hard drive temperature about 40, normal, exclude.

Top command view, memory and CPU resources. The result is normal.

Sensors check the hardware temperature. Results The CPU temperature is normal.

Graphics card temperature 93 degrees, not normal. And then the landlord all kinds of toss finally with a sentence command

Echo Low>/sys/class/drm/card0/device/power_profile

As a result, the graphics temperature decreased by nearly 30 degrees. The notebook is not hot, but the fan is still in a crazy turn.

The internet said that the temperature is more than 60 degrees, the fan will turn wildly.

Finally, the landlord compromised. Finally, the problem with graphics card, the fundamental problem is that Linux for high-performance graphics driver support is not very good. Causes the graphics card to always run at high performance.

The Echo Low>/sys/class/drm/card0/device/power_profile is executed under root to minimize power to the video card. For Linux developers, the chances of using a high-performance graphics card are still relatively small.

Summary: Although the results are not satisfactory, it is better than replacing a notebook or automatically downtime. Life does not toss, where is life. Toss in progress, toss in learning.

Read a lot of English materials, very good. Come on.
