[Bug 472406] Re: xorg consumes up to 25% of CPU after upgrading to Ubuntu 9.10

[manolo]

SOOOOOOOOOOOOOOOOLVEEEEEEEEEEEEEEEEEEEEEEEEEDDDDDDDDDDD!!!!

Albert, thank you very much! The nightmare terminated, although the
solution has been not so immediate!!!

I've been trying to upgrade to kernel 2.6.31 as you suggested but after installing through Synaptic and rebooting, my surprise to find out that the new kernel did not appear into the Grub2 menu list !!!
Also, after installing the new kernel for the first time, I realised that neither Synaptic marked that kernel as "installed". Actually no kernel was marked as "installed". Actually, as far as I can remember, a couple of days ago Synaptic notified about that 2.6.31 kernel upgrade: I ran the upgrade but, AFAICS, it didn't installed it.

So, getting back to the point, after installing the 2.6.31 once more I decided to run 'sudo update-grub' which retrieved the new kernel but actually did not updated /boot/grub/grub.cfg
So I've been trying to "manually" add the 2.6.31 line into the grub2 menu. My first try was 'sudo gedit /boot/grub/grub.cfg' but it didn't saved my changes because of "read only file system" !??!?!?!
I also tried to open gedit as super user (I run the 'su' command first) but still no way to save changes for the same reasons.

So my last try was to modify grub.cfg using 'pico' from command line:
sudo pico /boot/grub/grub.cfg

and I did was able to save the f*ck|ng changes!!! In detail I added the lines related to 2.3.31 just copying the lines related to the old kernel and modifying a very little bit accordingly :)
My grub.cfg is attached to the present post.

Hope it helps Ride and all the others experiencing this problem too.
Albert, thank you one more :)
