Unhappy Error : After Installing linux-kernel-pae and Binaries


I read in some website and thought of giving a shot at the pae enabled kernel as i was having 6GB of RAM available in my system. I couldn't use 64bit system because i have a lot of applications that are not available in 64bit. I use a few customised software (From my office corporate) they are 32bit too.
Here is what i did..

sudo install linux-generic-pae
It installed a few headers and packages additionally required.
and i did a reboot.

Bingo...

Now i'm stuck in a terminal mode linux...
It asks for logging in in terminal.

I tried logging in and thought of starting xWindows System manually but all failed..

I have A Nvidia Driver that has some issues with the kernel.

Ok now I'm done experimenting... Please help me to recover from the problem...


I need to revert back my system to a prior state where everything was fine with the linux-kernel-generic..

I use the latest ubuntu 10.10 with complete updates
I use the latest kernel from ubuntu.. ie 2.6.36...

Please help me to recover to the old state where i was happy to use just 3GB of RAM..

I cannot open GRUB during startup by pressing [SHIFT] or [Esc].
I don't have any other OS installed.


I am gonna remove my 2GB +1GB RAM and going to use remaining 3GB happily,,

Thanks..


An alternate solution to use all the 6GB is also welcome... using the current pae enabled kernel.. do i need to install any additiona drivers..

While i try to load Xwindows.. I get the following error..

A long error report is generated and at the end "No Xwindows system installed.."

I would log in and then
Code:
sudo nano /etc/default/grub
and comment the following line
Code:
#GRUB_HIDDEN_TIMEOUT=0
this should enable you to have the grub menu displayed when you boot.
Secondly, since it seems that you are using nVidia's proprietary drivers, I believe that you need to reinstall the nvidia drivers each time you install a new kernel. I really don't know since I have an AMD card.

Thanks Mate that solved the issue.
Here is what i Did..
  1. Logged into Ububtu 10.10 (the PAE kernel)
  2. Typed the command
    Code:
    sudo nano /etc/default/grub
  3. Commented the line
    Code:
    #GRUB_HIDDEN_TIMEOUT=0
  4. Saved the file and updated grub.
  5. Rebooted the system
  6. Thats all

Now i Unistalled the pae kernel and rebooted.
I set the grub to the previous default(removed the comment)
Now my system looks as nothing happened..


Really thanks for a truly FAST reply...

That is correct.

I don't know how the OP originally installed the nVidia driver, so I can't give detailed instructions on how to reinstall (I don't know Ubuntu very well anyway) but ...

I'm pretty sure that is not correct. The Nvidia driver works just as well with the PAE driver as with the non PAE driver.

The problem is the Nvidia driver does not work across any change in the kernel unless you reinstall the Nvidia driver after changing the kernel.

Even if you stay with the non PAE kernel, there will probably be some kernel update sent out that will cause the same problem.

I don't recall/understand the details of the following and I've seen it sometime work and sometimes fail, but there is a package manager wrapper for the Nvidia proprietary driver that (when things work right) causes subsequent kernel updates to coordinate with the Nvidial driver so that you don't need a manual reinstall of the driver after each kernel change. I think Ubuntu has instructions for installing the Nvidia driver so that all works.

Also for current Ubuntu, you might not even want the Nvidia driver. The old open source nv driver was usually so bad that using the proprietary driver from Nvidia was a clearly better choice. The new open source driver (nouveau) is much better.
