make a wrong initrd.img when installing

[fadying]

The last step of installing make a new initrd.img of wrong version which I've just deleted.
So it makes no different. What can I do about it?

I assume that you're talking about bbswitch. See the manual page of update-initramfs. To build it for a different kernel, use something like update-initramfs -u -k 3.2.8+

Thank you very much. Then I try to start bumblebee like
sudo bumblebee -d
"/usr/local/sbin/bumblebee: line 262: /var/run/bumblebee.pid: cannot overwrite existing file" appears, and stop with
"^C/usr/local/sbin/bumblebee: line 334: /var/run/bumblebee.fifo: Interrupted system call"

That's Bumblebee 2.4, the latest version we support is 3.0.

I thought it will auto install the latest version.
By the way, my kernel version was also too old. Then I installed the linux-3.2.9. It got stuck with
"$ sudo make install
sh /usr/src/linux-3.2.9/arch/x86/boot/install.sh 3.2.9 arch/x86/boot/bzImage
System.map "/boot"
run-parts: executing /etc/kernel/postinst.d/dkms 3.2.9 /boot/vmlinuz-3.2.9

• dkms: running auto installation service for kernel 3.2.9

•   nvidia-current (295.20)..."

bbswitch is a kernel module, Bumblebee is a program. The daemon is named bumblebeed in 3.0, bumblebee is old cruft from the 2.4 series. Try bumblebee-uninstall if it exists and reinstall Bumblebee 3.0

Is kernel version >= 3.1 necessary? I failed in it as I said above

[Lekensteyn]

Kernel version 3.1 is not necessary, but you must not mix up Bumblebee versions.
