So I updated the kernel to 3.26 from the original 3.25 that was installed by default with my Ubuntu 12.04 x64 installation. Ever since I've updated the kernel, the mouse just stops working randomly. Unplugging and replugging it doesn't work I have no idea why this happens and how to fix it.

The system itself is fine, I can still alt+tab etc. Luckily, I've installed Gnome Do, so I just do a "sudo reboot" whenever that happens and after a reboot, everything is back to normal.

Please help me fix this erratic mouse issue

A bit of googling revealed this to be a known issue with 12.04, however there's no mention of a specific kernel, which is unfortunate because this issue only started for me after I updated the kernel.

How can I install the 3.25 kernel and keep it alongwith the new kernel? I basically want the 3.25 kernel to appear in the grub kernel list which I see on boot up and want to be able to boot using that one.

Just edit the Boot loader (grub) to show the prior kernel -- unless you used janitor it should still be there....
It hold onto the last 4 by default before it gets rid of them... just make the old one the default.

for gurb 2

I think it uses grub 2 --

You can also use the above to edit the boot order to default on the old kernel
There is no reason to reinstall the old-- it is still there--- It maintains the old for issues... such as a failed update in order to allow it to boot for a rescue or re-install.

Thank you!!

I followed one of the guides there and it turns out that the grub boot menu entry for the .25 kernel was listed under "Previous linux versions" in Grub. I had chosen to ignore it earlier as I wasn't expecting it in there.

I opened up the grub config file and that's how I got to know it's still there, as a submenu, under 'Previous Linux versions'. I'm back to booting with the .25 kernel... so far so good

Thanks again!
