Upgrade Fedora15 kernel to 3.0.4

The kernel version of Fedoar15 is 2.9.40. For some reason, the driver of the wireless Nic can work, but the wireless Internet access efficiency does not exceed 50 K/S. I tried to change the driver and the effect was not improved. Although some people say there is no substantial difference between the 2.9.40 kernel and the 3.0 kernel, they still tried to manually compile the linux3.0.4 kernel and install it successfully. After the installation is complete, the wireless Internet access speed is improved. The following are simple steps for upgrading. 1: Go to www.kernel.org to download the kernel source code 2:

If you have installed Fedoar 15 and the kernel version 2.9.40, the driver of the wireless Nic can work, but the wireless Internet access efficiency does not exceed 50 K/S, and you have to change the driver. The effect is not improved. Some people say that there is no substantial difference between the 2.9.40 kernel and the 3.0 kernel, but they still try to manually compile the linux 3.0.4 kernel and install it successfully. After the installation is complete, the wireless Internet access speed is improved.

The following are simple steps for upgrading.

1: Download the kernel source code at www.kernel.org.

2: Decompress the kernel to/usr/src/kernels/

3: ncurses is installed and ncurses-devel is not installed.

4: make menuconfig can be set by default. Because my current version cannot keep up with the trend of the times and the memory is 2 GB, I was planning to cut off the PAE option (supporting large memory) function in the kernel, to reduce unnecessary calculations, but can be removed. Khan ......

5: make all

6: make modules_install

7: make install

8: select the newly compiled kernel at startup

The graphic interface cannot be started because of the video card.

1. Enter the grub option when starting the system, modify the newly compiled kernel startup parameters, and add the number 3 at the end to indicate that the startup level is 3 (runlevel 3 ).

2. reinstall the graphics card driver (NVIDIA)

3. reboot troubleshooting
