Hi Ravi

will you try following ... and post the result here ??



  1. If you have Grub 2 set to boot without displaying the menu at all, 
hold the SHIFT key down until the menu displays. (In Grub it was the ESC 
key.)
  2. Press any key once the menu is displayed to 'freeze' it. Then 
arrow to the kernel you want to boot.

  3. Press "e"
  4. Scroll to the end of the "linux /boot/vmlinuz" line. If 
displayed, remove "quiet" and/or "splash". Add the word "single" to the 
end of the line.

  5. Press CTRL-X to boot to the Recovery menu.

Is it OK to skip/jump updates?

What I mean is if i have a package version 1 and a few days later 
version 2 is available, can i skip it and update directly when version 
3 or 4 is available? For packages that have many dependencies will 
this have a possibility of breakage or dependency issues?


This is only for updates thru Update Manager and does not imply 
complete distro updates.

almost yes ... ( dependencies will be added automatically  by 
apt/synaptic or  yum ( RHEL/Fedora )

Ravi

will you try following command

sudo grub-install --root-directory=/media/root /dev/sda

I'm not sure but invalid or unsupported executable format  is 
usually a result of a mapping error on grub , but you seem to have it 
mapped correctly. I can only guess that the device.map might be wrong, 
try checking /boot/grub/device.map and see if /dev/sda is actually (hd0) 
like grub thinks it is

Re: [ubuntu-in] facing pb on ubuntu 10.4

[sivakumar bharadhwaj]

Dear Sir,

I too had faced the same problem - the very first day I installed 10.04.

But, I went to the -> system -> Power Management Preferences :

- On AC Power  -> set display brightness : to the required level ( i did
0%)

and

- On Battery Power -> checked OK to the Reduce backlight Preferences

and
-> On AC Power -> Pressed 'Make Default'

>From then on the display brightness - remains the same - for the past 20 -
25 days, AS SET BY ME.

Hope this gives you - solution for atleast the Brightness Problem - which
generally irritates.

Forgive me, if this is not a solution,

Its a bug in Lucid [1]. You can confirm it by visiting the link below
and mark the bug as affecting you (Click on the link that says "Does
this bug affect you?" and then "Yes it affects me"). However, first read
through the description of the bug and check if it is the same problem as
you are facing. As of now, I don't think anyone has come up with a
solution or work-around. But if many people report the same problem, it
might be taken up on urgent basis.
