Kernel 3.10.1 – Update your Linux kernel…

Standard

Linux Kernel 3.10 stable has been made available not more than a month ago and it has already reached it’s first update stage. Kernel 3.10 series has seen a bit of issues recently with its 3.10.2 release that supposedly interfered with a few previously-proper working nVIDIA graphics cards.

Kernel 3.10.1

We’ve tried it ourselves and not found any issues with it but we recommend you steer clear of 3.10.2. As of now Kernel 3.10.3 has not been extensively tested so we’re back to the latest stable release – Kernel 3.10.1. We’ve ourselves had 10 days to test it and you can rest assured it will work.

Issues Kernel 3.10.1 fixes

  1. cpufreq: Fixed CPU frequency regression after suspend/resume
  2. SCSI: sd: Fix parsing of ‘temporary ‘ cache mode prefix
  3. nfsd4: fix decoding of compounds across page boundaries
  4. libceph: Fix NULL pointer dereference in auth client code

The complete change-log for Kernel 3.10.1 can be found here, although why bother?

The tutorial here will help you install the latest working kernel, in our opinion, on your Debian based Linux systems including Ubuntu and Linux Mint. It will use a simple bash script that will facilitate the installation process, but if you want to install it manually and prefer to follow the entire procedure in manual steps you can go ahead here.

Installation of Kernel 3.10.1

  1. Open up the terminal. Do it however you like. We like [Ctrl][T].
  2. In the terminal enter the following commands one by one. Wait for each individual command to execute properly.

cd /tmp

wget http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.10.1 -O kernel-3.10.1

chmod +x kernel-3.10.1

sudo sh kernel-3.10.1

  1. Of course, for all of it to take effect you’ll need to restart your PC. If you’ve closed the terminal already, that’s a shame; restart it in whichever way you prefer. If you’re one of the cool guys or gals enter the following.

sudo reboot

And that’s it! Play around with your system and find out if it fixed any of your issues.

Removing Linux Kernel 3.10.1

There’s a chance you might not like the latest working Linux Kernel. Of course, we wouldn’t share the installation process unless we were sure it was working. If you’re discontented due to any reason, you can revert to an earlier state using the following command.

sudo apt-get purge linux-image-3.10.1*

Kernel 3.10 Stable for Linux: Install it on your system…

Standard

Update: Kernel 3.10.1 is out and you can get it here by following the steps on the tutorial here.

Linux has been, for quite a long time, the base to most open-source consumer operating systems like Debian, Ubuntu, Linux Mint, etc. The key is its kernel that like Linux itself is forever getting better. The Linux Kernel 3.10 has recently arrived, and this stable release has been made available, bringing more new features and improvements.

Kernel 3.10

Features of Kernel 3.10

  • The integration of BCache SSD/HDD caching framework
  • Native UVD video decoding support
  • Improved support for Intel Haswell micro-architecture for Linux
  • More improvements for power management, etc.

We’ve searched for an official change-log but didn’t find one. You could visit this link to see if a change-log arrives for kernel 3.10 if you feel skeptical of the process.

Here, we will see, as usual, how to upgrade to this new kernel using a simple bash script as shown below. The kernel is the official one and would work on every system based on Debian including Ubuntu and Linux Mint. Performance improvements may be seen depending on your system – it’ll get better if this update addresses any of your issues. However, we do need to remind you that installing a new kernel may render your operating system unusable, so install it at your own risk.

Linux Kernel 3.10 Installation

Make sure your system is either Ubuntu or Linux Mint or any distribution of Linux you’re sure that is based on Debian only.

1. Open up the terminal window.

You can do it any way you like. We like [Ctrl][T].

2. Enter the commands.

Enter these commands one after another, in the exact sequence. Wait for each of them to complete at their own pace. You’ll need a steady internet connection for this.

cd /tmp

wget http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.10 -O kernel-3.10

chmod +x kernel-3.10

sudo sh kernel-3.10

3. Do a system reboot.

It can be simply done by restarting in the traditional way. OR you could enter the following in your terminal window if it’s still open.

sudo reboot

Removing Kernel 3.10

There are times you might not like to continue using this kernel. It might end up hurting your system more than it improves it. You can revert to your stock kernel if you wish so.

To remove kernel 3.10 from your system, enter this command:

sudo apt-get purge linux-image-3.10*

That’s it for Kernel 3.10 Stable. Do let us know your experiences and tell us if you’ve managed to fix your issues if any. Ciao!

Kernel 3.9.7: Upgrade to the latest Linux Kernel…

Standard

Linux has been ever changing, ever evolving with its Kernel 3.9 series. Linux Kernel 3.9.7 brings in more updates and improvements.

Kernel 3.9.7

The following are what we could understand from the official change-log. If you wish to read the whole thing here it is.

  • USB: spcp8x5: fix device initialisation at open
  • powerpc: Fix missing/delayed calls to irq_work
  • x86: Fix typo in kexec register clearing
  • wl12xx: fix minimum required firmware version for wl127x multirole
  • cciss: fix broken mutex usage in ioctl
  • Bluetooth: Fix mgmt handling of power on failures

Linux Kernel 3.9.7 Installation

This kernel 3.9.7 can be installed in all of Debian based Linux distributions like Ubuntu and Linux Mint. As with any core level Linux stuff, we’d recommend using it only if you wish to rectify problems with your system. Follow the procedure at your own risk. If you find any of the steps difficult to comprehend, don’t do it.

Open up a terminal window and enter the following:

  1. Make the temporary folder your current focus.

cd /tmp

  1. Run these commands one after another in that order and be patient. Let each of them complete at their own pace.

wget http://dl.dropboxusercontent.com/u/47950494/upubuntu/kernel-3.9.7 -O kernel-3.9.7

chmod +x kernel-3.9.7

sudo sh kernel-3.9.7

  1. Reboot your system. If you closed your terminal window already, do it the traditional way. Our way is by entering the following commands.

sudo reboot

Removing Kernel 3.9.7

We totally understand the procedure above may create more problems than it solves. So if you’re one of those unfortunate ones – we aren’t – then you could use the following command to revert to your stock kernel.

sudo apt-get purge linux-image-3.9.7*

Do let us know if it fixed any of your issues. Actually, you can tell us anything you want. We’re all friends here…

nVIDIA drivers installation for Spherical Cow

Standard

This guide will help you in install nVIDIA drivers. The drivers are proprietary and officially supported ones. Installing these on Fedora 18 “Spherical Cow” disables the generic Nouveau driver. It works with nVIDIA GeForce 8/9/200/300/400/500 series graphic cards. It also supports nVIDIA GeForce 6/7. Newer drivers might appear in the future for GeForce 6/7 cards, which is when you’ll be able to upgrade them too.

Fedora 18’s installation for nVIDIA drivers is not much different from previous versions of Fedora. We have tested this guide with a couple computers. Do try it out and let us know, if you have any problems with this guide or the installation process on your system.

nVIDIA drivers

ON

Spherical Cow

1. Pre-requisites for nVIDIA Drivers installation

Just for your peace of mind…

1.1. Before nVIDIA drivers installation

Enter the following command in a terminal window, to know about the current video card.

lspci |grep -i VGA

The following is an example output. Abort this entire process if you find out that your system doesn’t have an nVidia.

01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce G210] (rev a2)

1.2. nVIDIA Optimus Technology

If your output looks like following,

00:02.0 VGA compatible controller: Intel Corporation 2n Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation GF106 [GeForce GT 555M SDDR3] (rev a1)```

You should know that your computer has nVidia Optimus Technology. If you can turn off the Intel graphics, do it by whatever method your system might support. If it is impossible to turn nVidia Optimus off in the BIOS, then pardon us, this guide won’t work for you.


## 2. Main process

#### 2.1. Change to your system’s root user

`su -`

`## OR ##`

sudo -i


#### 2.2. Run on your latest kernel

If you’re not currently running the latest kernel then use the following commands to upgrthen update kernel and reboot

yum update kernel* selinux-policy*
reboot“`

2.3. Add RPM Fusion Repositories (Free and Non-Free)

Works for both 32-bit and 64-bit.

You should run only one of them, not all. The commands below are those you can choose from

yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm

OR

yum localinstall --nogpgcheck http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-18.noarch.rpm

2.4. Install nVIDIA proprietary drivers for GeForce 8/9/200/300/400/500 (and currently GeForce 6/7) series cards

Select akmodkmod or kmod-PAE from following.

akmod-nvidia

yum install akmod-nvidia xorg-x11-drv-nvidia-libs

For the extra package for kernel-PAE users

yum install kernel-PAE-devel

OR

kmod-nvidia

yum install kmod-nvidia xorg-x11-drv-nvidia-libs

OR

kmod-nvidia-PAE and kernel-PAE-devel

yum install kernel-PAE-devel kmod-nvidia-PAE

2.4.1. akmod recommendation

We recommend akmod as it is very easy and avoids problems that might occur on kernel updates. It is the best option if you ever use any of the following in any combination:

  • Self-compiled kernel
  • Older Fedora kernel
  • Quickly changing kernels from updates-testing/rawhide

For the full specifications and difference between kmod and akmod, check this out.

2.5. Have a system reboot

Do it either the old fashioned way or our way – provided you haven’t closed the terminal window already.

reboot

2.6. VDPAU/VAAPI support

This is the ability to use video acceleration for OS tasks. To enable video acceleration support for your player (Note: you need Geforce 8 or later).

yum install vdpauinfo libva-vdpau-driver libva-utils

Congratulations, you now have nVIDIA Drivers installed on your system.

Uninstall proprietary nVIDIA drivers

We’re sure you’d be delighted to use the native nVIDIA drivers for Spherical Cow but would totally understand if you decide to revert to the Nouveau drivers. You can do that too. We assume that you’ve installed nVIDIA drivers using our guide above. Uninstallation happens as follows.

3.1 Change root user

su -

OR

sudo -i

3.2 Uninstall nVidia Driver Packages

yum remove xorg-x11-drv-nvidia\* nvidia-settings nvidia-xconfig

3.4 Then Reboot System

reboot

And that is all. Do leave us feedback – always appreciated.
