General :: CentOS - Safe To Remove The First Kernel In The Installed List To Save Having Two Kernels Being Updated Everytime?

May 8, 2011

When I run yum list installed command the output shows two kernels:


Would it therefore be safe to remove the first kernel in the installed list to save having two kernels being updated everytime I run yum update? Or is the PAE kernel dependant upon the original?

Fedora :: Save A List Of Installed Software?

Mar 31, 2011

Since Fedora isn't a rolling release distro like I'm used to, I was wondering if there was a way to save a list of installed packages to make the next upgrade easier. I'm eagerly waiting for FC15, but still on FC14, and I would like to know if there's a way to export a file that yum can reference to reinstall what program titles I already have installed.

CentOS 5 Server :: Updated Fresh 5.3 Xen Kernel And PAE Support Disappeared?

Aug 26, 2009

I have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)

General :: Safe To Delete Installed .tgz Packages?

Mar 8, 2011

i read somewhere (I think an article by AlienBob) that you needed to make sure .tgz packages where located in a safe place as opposed to the home directory so as to prevent accidental deletion.

I have a number of .tgz packages that I have already installed and moved to the /bin/ directory for safe keeping, but its not very orderly, ya' know?

Is it safe to delete/rm these .tgz files? Im assuming that the installpkg command extracts the creamy nougat inside and puts it somewhere useful.

Also, even if it is safe to delete, what is best practice in this case? keep them forever in some isolated directory?

I would like to get the output from 'yum list installed' from a standard CentOS 5.1 32bit installation on a Intel desktop PC.

General :: Kernel Mode Setting Sets Wrong Resolution On Console/Intel GL40/several Kernels

Feb 21, 2010

Basically, About 50% of the time, the system boots and sets the console resolution to something strange, and the console renders in a small box in the top-left hand corner of my screen. This causes problems not only with the display of the console, but with the display of X as well.

I have an Intel GL40 chipset on this laptop, with an integrated GMA4500 GPU. I am using the latest stable Intel video drivers (2.10.0-1), and have tried using the git drivers. In addition, the problem has been occuring since December, when I install Arch linux on this machine, I have just now had the time to address it. So basically, the issue has persisted with all driver versions since mid-December to the latest releases.

In addition, I have tried using several kernels, including:

But the problem persists with each.

I wish I could give you relevant diagnostic information for this issue, but if I had any idea where to start...

I will gladly post any information necessary. I was going to post a copy of everything.log for a successful and unsuccesful boot, but unfortunately they put me over the posing limit by about 100,000 characters each.

I guess, on second thought, that my Intel video driver really wouldn't have anything to do with my console, now would they?

Ubuntu :: Grub2 - Removing All Old Kernels From List

May 21, 2010

I'm simply trying to remove old kernels and second rename things that are on the list. It used to take me 10 seconds with grub1, but having some difficultly with grub2. So far I went into /boot/ and removed the old kernels and then did a sudo update-grub2 and it seemed to remove all the old kernels from the list. Is this the best way or doing it or any issues on doing it this way? Second I just want to rename what boots up like Ubuntu 2.6.32-22-generic to something else. I keep read not to modify the grub.cfg, but not sure what to do? I poked around the files in /etc/grub.d/, but not sure what to do?

Ubuntu Installation :: Only Partial List Of Kernels In Grub?

Aug 26, 2010

I have Ubuntu 8.04 (32-bits) installed on /dev/sda and Ubuntu 10.04 (64-bits) installed on /dev/sdc (this is an update from 8.04 64-bits originally installed on /dev/sdc).

Ubuntu :: Using Wget To Save A Frequently Updated Webpage?

Mar 3, 2010

I'm trying to figure out how to use wget to save a copy of a page that is frequently updated. Ideally, what I'd like it to do is save a copy of the page every minute or so. I don't need multiple copies; I just need to know what the most recent version was. Also, if the page disappears for whatever reason, I don't want it to save the error page, just wait until the page is up again.

OpenSUSE Install :: 11.2 From DVD - Load Kernel Operation Hangs At 97% (using Both Normal And Safe Kernel)

Feb 23, 2010

I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)

When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.

CentOS 5 :: Kernel Yum Update Installed But Not Working

Aug 17, 2009

I try to update my kernel to using
# yum update

After # yum update # rpm -qa kernel*|sort gives the following:
kernel-devel-2.6.18-128.1.14.el5 .....

This my grub.conf:
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img

yum update installed:
CentOS (2.6.18-128.4.1.el5.centos.plusxen) and
CentOS (

both are not working. I have to run the system using: 2.6.18-128.1.14.el5. Upon trying again #yum update it says that no packages are marked for update. Can I manually install the desired kernel? Do you know a reason why yum update is not automatically installing the proper kernel?

Ubuntu Installation :: How To Manually Remove Old Kernels

Oct 20, 2010

I did a "dirty install" of Maverick over my existing Lucid system. That went very well and I am having no problems with Maverick. However, this morning, I decided to clean off the old Lucid kernels. In the past, after installing a new kernel on the same Ubuntu release, I have done this by running "aptitude search 2.6.32-24", for example, then running "sudo aptitude purge" for the kernel and header files it found.

Now that I have changed releases, aptitude no longer finds the Lucid kernels installed on my system, even though they still reside in the file system and show up on the grub2 menu. So, how do I manually find everything necessary to delete for the old Lucid kernels?
