I recently installed ubuntu 9.10 and a day later updated with all the suggested security and recommended updates. Now I notice that in my Grub there are two different kernel versions listed. Are they both necessary? Can I / should I get rid of the older one, and if so, how?
I ask because after all these updates I notice my computer runs much slower, so I don't want it overloaded with unnecessary software.
After I messed up badly with my netbook I have to reinstalll the OS, it is a government property netbook that came up with Edubuntu 7.04 insalled on it. I shouldn't mess with the filesystem but I did and now I have to install Edubuntu from the beginning, but I must be sure that everything will just like I have done no change, so I am afraid that I can make some mistakes at this pointThe first thing that I want to know is: Why there are multiple kernels listed at the GRUB (v 1.5)...this is the full list:
Ubuntu, kernel 2.6.28.9 Default
Ubuntu, kernel 2.6.28.9 Default (recovery mode)
Ubuntu, kernel 2.6.28.9
[code]....
I have a dual boot desktop with WinXP on C: and Ubuntu on D:. GRUB 2 handles the start-up. Having installed multiple updates to Ubuntu, my GRUB menu now lists:
2.5.31-19-generic
2.5.31-17-generic
2.5.31-16-generic
2.5.31-15-generic
2.5.31-14-generic
and (recovery mode) for each of the above, along with the mem test and WinXP.Is there any reason I need to list all these variants of Ubuntu? If not, can I simply edit them from the GRUB config file or must I do something else to actually uninstall them?
After I used Ubuntu Tweak to delete several kernels (versions) of Ubuntu under Package Cleaner, all these deleted kernels in Ubuntu still show up whenever I start my PC as if nothing was deleted.
View 9 Replies View RelatedI am using the latest Nvidia driver from their website on Ubuntu 9.10. I use 2 kernels, the standard kernel for everyday use and the realtime -rt kernel for my music work. On my desktop i have standard ubuntu and ubuntu studio installed but on my laptop its annoying having to have an external hard drive plugged in when i want to record so i just switch between kernels on a standard install. The problem is i have to reinstall the nvidia driver every time i switch between them or if the kernels get updated (which i don't mind so much). Is there any way i can install the driver so that it configures x.conf to work with both kernels without having to reinstall each time?

View 2 Replies View RelatedI can't find the place to set the system to keep multiple kernels. For the first time in a long time, updates are giving me grief. I've kept the last working nvidia driver in case I need it.
Now I would like to keep one old kernel when I update to the new one. I had a lab rat that never got rid of old kernels and that was too much. It is possible to keep the last working kernel when you update, isn't it?
I'm running Fedora 12 - Linux 2.6.32.21 with a boot partion on /dev/sdb3 of a hard disk.
I downloaded a vanilla kernel version 2.6.35.4 and have built it and run it successfully. I built this kernel to play with building device drivers.
My grub configuration uses the same root filesystem for my fedora installation as my vanilla 2.6.35.4 kernel; both use the LVM root filesystem. (/dev/sd4 /dev/sdb5 /dev/sdb6)
When I'm running fedora 12 (2.6.32.21) I can see the files in /boot which contains my kernel, system-map, initramfs, grub directory, etc. I also see my vanilla kernel 2.6.35.4 and it's associated support files (map, initramfs, etc.)
My question is when I boot into my vanilla 2.6.35.4 kernel and I look in /boot, I only see my vanilla kernel and it's associated support files. No grub, no fedora kernel. If I do a df -a, I see that /dev/sdb3 is not mounted like it is when I'm running my fedora kernel. I'm confused as to what is going on here. Can anyone shed some light on this?
Is it possible to remove multiple packages listed in a text file? Similar to "cat orphan.txt | zypper rm" or "zypper rm <orphan.txt." Neither worked.

However at start up Grub loads only 2.6.31-19 and below and there's no mentioning of 2.6.32 in grub.cfg while it is present in menu.lst. I tried to update grub with no success.
View 9 Replies View RelatedI have GRUB to allow me to boot windows and Ubuntu, i recently noticed that my list of kernels is getting clogged up with all the updates. So i went online to try and find out how to get rid of the unwanted partitions and also how to add new ones - i am going to attempt to hackintosh, and will need to know how to add kernels. What i found out was; the boot menu in GRUB had a file that is supposed to be called 'menu.lst' (Lst not ist), and that all i needed to do was edit this, that it wouldn't delete the kernels, but that i don't need to, i only need to add and remove links to kernels on the GRUB menu. The problem is that after looking, i don't have that menu.lst file, i have a file containing the image files for 'memtest', but not for my GRUB. I am using 10.04, i don't know what version of GRUB im using but i'm using whichever one comes with 10.04. Could someone please point me in the direction of the files i need to edit or what i need to do to add and remove kernels?

Graphic card is ATI Radeon HD 4570. BTW; I got no other problems what so ever. Everything works great really.
So today 2.6.31.17 came. to the b1tch of a cat sleeping on the keyboard, I was forced to a restart before I wanted.

How do I know which one I should use from the choice of 3 for the current kernelAnd if I understand which one to use, can I delete the others from the same imageAlso, in start-up manager I have choice of 4 from the drop down list?
Ubuntu disappeared from grub menu after I deleted the old kernels.
View 9 Replies View RelatedI ran grub-customiser to set default kernel, and saw the GFX mode setting, thinking "Hey, my monitor is native at 1440x900! I'll use that!" ...Didn't think about how the GFX card isn't initialized at that point, so my res is limited to 640x480... So the first problem was a system hang at the grub menu, with "Input Not Supported" displayed on the monitor.I changed the GFX mode back, and ran update-grub, and with a grin on my face, I rebooted. The grin went away fast, when I saw that none of the kernels showed in the grub menu, and I have only the two memtest entries. It appears that, while all the files are still intact, grub is not seeing the kernels. I had an idle partition of about 13 GB on hand, so after trying all sorts of things, I did a clean install on the little 13 GB partition. Still no dice, after doing an apt-get purge grub etc etc etc on my main Ubuntu partition, to make sure that the new grub was running. I still have only memtest, even though I can open the /boot directory and see the kernel files. I tried going into the grub command line and starting manually, but tab-complete does not suggest any of the kernel files, and tells me that the files do not exist, if I type in their full names.

I have at least 25 different Versions listed in my GRUB Screen but they are not in the menu.lst !?
I only use 2 of them.
I recently upgraded to 10.04, but it gave me a heap of problems, so I've reinstalled 9.10. Everything seems to be working again, but Grub seems to think that the 2.6.32-24 kernel is installed.When I try to boot it, it gives me a ton of errors that basically say it can't find what it's supposed to mount, so I'm assuming that it's left over from Lucid.Thing is, I can't find the kernel in synaptic to uninstall it, but when I update grub, it still lists it as being there.

There is a grub on each of these two disks. Both are the old grub (prior to version 2). Here is the top kernel listing from /dev/sda:

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.
However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.

Here is my current grub.cfg:
(How do I remove *.14 *.21 *.22 from my menu entries Ubuntu-tweak is not an option for me. I like it old-school or with the tools at hand.)
Code:
I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.
I have this strange problem on ubuntu 10.04 64 bit, that when running update-grub, it will only put the oldest kernel into the grub menu, despite the fact that I have recent kernels around as well.
in particular:
Code:
# update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst

I'd like to see the most recent kernels in the grub menu, with the most recent being on top.
I'm sure there is a thread on this somewhere, but after looking though the first 100+ search results, I can't seem to find it.
After a kernel update today, I noticed that new kernels are not being added to my grub menu.lst (so consequently, I was running an older kernel).
Any obvious reason why this would happen (kernels being installed normally, with yum update)? I thought the whole process was supposed to be automagic.
Would it have anything to do with the fact that I just kept my F11 menu.lst, and added a F12 kernel to it when I installed F12 (to a separate partition), then eventually (today, finally) removed the f11 kernels from it?
Here's my menu.lst, in case it's useful:

I have a extra OS listed in my grub menu. I'm dual booting Ubuntu 10.04 and Windows 7. I am able to boot into both Ubuntu and Windows. 30_os-prober has two menu entries for Windows though. The first one is Windows 7 (loader) (on /dev/sda1) and the second is Windows Vista (loader) (on /dev/sda2). My laptop came with Windows 7 and had 4 primary partitions (System, Windows, Recovery, HP_TOOLS). After making my recovery disks I removed the Recovery partition and shrunk the Windows partition to make space for Ubuntu. So Windows 7 (loader) (on /dev/sda1) is the System partition which I select to boot Windows. Windows Vista (loader) (on /dev/sda2) is where my Windows 7 is installed.

I have a grub menu with a ton of old kernel entries that I want to delete. I've scoured this forum, and haven't found anything that works. I've tried:
Code:"the easiest way to get rid of old kernels from grub is to uninstall the package, the post-install scripts will update grub
for example my current kernel is:
uname -a
Linux hemma 2.6.31-16-generic #53-Ubuntu SMP Tue Dec 8 04:02:15 UTC 2009 x86_64 GNU/Linux
then remove older kernels found in /boot like this:
sudo aptitude remove linux-image-2.6.31-15-generic" When I tried that, the output showed the package being removed, but nothing was removed from the grub menu. I tried running the kernel I supposedly removed, and it wouldn't start, which is promising, but how do I get it out of the grub menu? I've also tried using Synaptic, but that didn't work either.
I have two listing of windows 7 listed in Grub (I'm not sure why.) and I would like to know how to remove one if I can.
View 9 Replies View RelatedEver since the intro of Grub2, on the main Log-in screen, there is a "User" listed at the bottom of whoever is listed on the Users Log-in. Just what or who is this used for?. If it is 'clicked' on, then it asks for a password, as if 'it' is some kind of "user". But, as I don't know just what 'it' is for, therefore I also don't know 'its' password either.

View 14 Replies View RelatedI'll get directly to the point, I've installed Ubuntu, Linux on the same partition as Windows 7. Everything works just as it should be, no problems and I'm actually enjoying Ubuntu. It's a nice and clean OS.
Now, I'm having trouble with the GRUB, since I have updated Ubuntu a few times. It's not a large problem, but I don't like it around.
I attached a picture of my GRUB, it may take too many words to describe what's going on, so see for yourself.
(tangent to my other thread "Karmic -> Lucid not booting"). I have four hard drives on a Lucid box, and (as it happens) the fourth drive is the boot and root. Could I also install grub on the other three (ext4) hard drives, keeping the same root? Will this disturb the data there? How would the machine decide which copy to use, anyway?
