As you know, when you're upgrading your Linux Kernel and restart, your nvidia driver need to be compile for the new kernel ( This is only apply to manual installed Nvidia driver, if you installed your driver from Hardware Drivers, so you don't have to recompile it )

In this post, I'll show you how to automatically compile nvidia driver when you installed a new kernel.

Firstly, you'll need the driver, you can get it from nvidia.com, or as you manually installed nvidia drivers, it should be downloaded already. Move this file to /usr/src/ folder and rename it make a symbolic link named nvidia-driver. For example, when you have the beta driver 185.19:

sudo install NVIDIA-Linux-185.pkg.run /usr/src
sudo ln -s /usr/src/NVIDIA-Linux-185.pkg.run /usr/src/nvidia-driver

So you had the property driver, each time you upgrade your driver, remember to edit the symbolic link to the new file. And now, open your favorite editor and copy those code.

#!/bin/bash
#
 
# Set this to the exact path of the nvidia driver you plan to use
# It is recommended to use a symlink here so that this script doesn't
# have to be modified when you change driver versions.
DRIVER=/usr/src/nvidia-driver
 
# Build new driver if it doesn't exist
if [ -e /lib/modules/$1/kernel/drivers/video/nvidia.ko ] ; then
    echo "NVIDIA driver already exists for this kernel." >&2
else
    echo "Building NVIDIA driver for kernel $1" >&2
    sh $DRIVER -K -k $1 -s -n 2>1 > /dev/null
 
    if [ -e /lib/modules/$1/kernel/drivers/video/nvidia.ko ] ; then
        echo "   SUCCESS: Driver installed for kernel $1" >&2
    else
        echo "   FAILURE: See /var/log/nvidia-installer.log" >&2
    fi
fi
 
exit 0

Save it as update-nvidia and then

sudo mkdir -p /etc/kernel/postinst.d
sudo install update-nvidia /etc/kernel/postinst.d

And now, each time you upgraded a new kernel version, your nvidia driver will recompile.

But what if you've upgraded a new kernel and the driver stopped working. I know that whenever you restart your PC, the driver will not get compile ( because the kernel will not call postinst anymore ). So the solution is: Run update-nvidia manually

sudo sh update-nvidia `uname -r`

Remember that `uname -r` is required for the script.
That's all, restart your computer and enjoy with nvidia

My Laptop died today, just when I press power on, the monitor shows many lines (colorful ^^) on it and the system stop booting. Read more...

Ko bằng lòng với số điểm thấp tè ở bài trước, đặt ra plan cho mình là đạt 5k 3DMark05 và 2k 3DMark06, ko biết là có thể có khả năng đạt được ko nữa.
Nhất quyết muốn điểm cao thì phải OC, ko dám oc mạnh tay lắm . Tạm thời Oc ở mức spec là 500/650 (DF là 400/500). Test Stable có vẻ quá ngon lành, thế là ra tay Bench luôn.

Từ trước đến nay tớ vẫn giữ quan điểm là driver stock của hãng sản xuất là xịn nhất, mấy bản mod driver hiệu năng ko bằng nó được...và tớ cài Dell OEM driver 101.43 cho con VGA 8400M GS thân yêu của mình.
