Install/Upgrade to Linux Kernel 3.18 in Ubuntu 14.04/14.10

Last updated: February 28, 2015

The stable release of Linux Kernel 3.18 has been released this weekend. Linus Torvalds wrote on the Linux Kernel Mailing List (lkml.org):

It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.

I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday
break.

So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with
Dave (and to make my life easier too ;) let’s try to avoid introducing any _new_ nasty issues, ok?

Linus

What’s New in the Linux Kernel 3.18:

The Linux 3.18 Kernel brings many great changes, here’s some of the highlights for end-users:

  • Unified Video Decoder (UVD) support for old ATI/AMD GPUs of the Radeon HD 3000 series.
  • Re-clocking improvements for AMD’s Radeon driver.
  • Userptr support for AMD Radeon GPUs.
  • Razer Sabertooth support and other hardware input devices improvements for gamers.
  • Faster suspend and resume for large Linux servers.
  • Btrfs and F2FS improvements.
  • Para-virtualized SCSI (pvSCSI) support for Xen virtualization.
  • DisplayPort audio support, fan control improvements and various other enhancements for open-source NVIDIA driver.
  • OverlayFS was finally merged into Linux Kernel 3.18
Install / Upgrade to Linux Kernel 3.18 in Ubuntu:

The Ubuntu Kernel Team has made the binary packages of this kernel release, available for download at the link below:

How to Install / Upgrade to Nvidia Driver 343.36 in Ubuntu 14.04

Last updated: December 6, 2014

While Nvidia’s Linux Graphics Driver 346 series is still in beta, the latest 343.36 stable driver has been released this Friday, which brings support for the latest Linux kernels (up through Linux 3.18), various bug fixes (including an Unreal Engine 4 fix), support for disabling indirect GLX, and more.

Release Highlight in Nvidia Graphics Driver 343.36:

  • Added support for X.Org xserver ABI 19 (xorg-server 1.17).
  • Improved compatibility with recent Linux kernels.
  • Fixed a bug that rendered very bright garbage data onto some textures in UnrealEngine 4 applications. This issue is known as the “disco bug” by the UnrealEngine 4 Linux community.
  • Added option UseSysmemPixmapAccel to control the use of GPU acceleration for X drawing operations on pixmaps allocated in system memory.
  • Fixed a regression that prevented the NVIDIA X driver from recognizing Base Mosaic layouts generated by the nvidia-settings control panel.
  • Fixed a bug that could cause VT-switching to fail following a suspend, resume, and driver reload sequence.
  • Fixed a bug that caused incorrect colors to be displayed on X screens running at depth 8 on some GPUs.
  • Fixed a bug that prevented GPUs from being correctly recognized in MetaMode strings when identified by UUID.
  • Implemented support for disabling indirect GLX context creation using the -iglx option available on X.Org server release 1.16 and newer. Note that future X.Org server releases may make the -iglx option the default. To re-enable support for indirect GLX on such servers, use the +iglx option.
  • Added the “AllowIndirectGLXProtocol” X config option. This option can be used to disallow use of GLX protocol. See “Appendix B. X Config Options” in the README for more details.
  • Fixed a crash with UnrealEngine 4 when the application was started with the -opengl4 commandline switch.
  • Fixed an OpenGL issue that could cause glReadPixels() operations to be improperly clipped when resizing composited application windows, potentially leading to momentary X freezes.
  • Fixed a bug that could prevent the GLSL compiler from correctly evaluating some expressions when compiling shaders.
  • Fixed a bug that could cause nvidia-installer to crash while attempting to run nvidia-xconfig on systems where that utility is missing.
  • Fixed a bug that could prevent 32-bit GPU-based applications from running correctly on 64-bit systems when using GPUs with very large memory-mapped I/O regions.
  • Fixed a bug that could cause the CUDA debugger to fail after exiting X on systems with persistence mode enabled.
  • Fixed a bug that could cause silent and intermittent failures when a CUDA application writes to a peer device’s memory with GPUDirect.
  • Updated nvidia-installer to avoid writing to non-zero offsets of sysctl files in /proc/sys/kernel.

How to Install / Upgrade to Nvidia 343.36 Driver in Ubuntu:

To make the installation easy, you can install/upgrade the driver from PPA. But at the moment of writing this tutorial, the PPA does not yet update with the 346.36 binaries.

Check out the package version of “nvidia-graphics-drivers-343” from the PPA page below:

xorg-edgers fresh X crack PPA

Once the PPA updated, run the commands below one by one in terminal to add the PPA and install the 346.36 driver:

sudo add-apt-repository -y ppa:xorg-edgers/ppa

sudo apt-get update

sudo apt-get install nvidia-343

(Optional) To uninstall the driver as well as the PPA, run:

sudo add-apt-repository -r ppa:xorg-edgers/ppa && sudo apt-get remove nvidia-343 && sudo apt-get update

If you don’t want to add the PPA, follow the steps below to install the 346.36 driver via the official package from Nvidia website.

1. Select download the 346.36 driver that matches your OS type:

64-bit Linux | 32-bit Linux | 32-bit Linux ARM

2. IMPORTANT: You have to switch to the black & white text console (press Ctrl+Alt+F1 ~ F6), then log in with current username & password.

3. When you’re in the text console, run the command below to stop the graphics session (The graphics session is still there, and you can press Ctrl+Alt+F7 to switch back).

sudo service lightdm stop

Replace lightdm with gdm or mdm in the code if you’re running with Gnome GDM or Linux Mint’s MDM display manager.

4. Once the graphics session is closed, you are able to run the downloaded package by running the commands below:

cd ~/Downloads/

chmod +x NVIDIA-Linux-*-343.36.run

sudo sh NVIDIA-Linux-*-343.36.run

Above commands will navigate current directory to /Downloads/, then give executable permission to the 346.36 driver package, and finally run the installer.

5. After the last command, follow the onscreen prompt until done. Finally restart your computer.

(Optional) To uninstall the 346.36 driver, get into the text console and run:

sudo sh ~/Downloads/NVIDIA-Linux-*-343.36.run --uninstall

How to Install The Real Ubuntu System on USB Flash Drive

Last updated: November 29, 2014

This is a step by step tutorial shows you how to install the real Ubuntu OS on USB stick to create a ‘Windows To Go’ style USB drive. Tested with Ubuntu 14.04

Requirements:

Before getting started, you need to prepare something:

  1. A 8GB+ USB Drive.
  2. A Ubuntu Live CD/DVD/USB. In the case below, I created a bootable Ubuntu Live USB from the .iso image.
  3. A computer with an operating system installed.

And always backup your data on the USB flash drive!

To get started:

In my case I have a newly bought 16GB USB stick, a 4GB old USB stick, and a laptop multi-boot with Ubuntu based systems.

1. I don’t have a Ubuntu CD/DVD, so I decided to burn the Ubuntu .iso image into the old USB stick. To do so:

  1. Download Ubuntu image: releases.ubuntu.com
  2. Download UNetbootin: unetbootin.sourceforge.net. For Ubuntu, install it from Software Center.
  3. Plug in the USB stick.
  4. Start UNetbootin, and burn the .iso image into USB

2. Plug in the bootable USB drive to your computer and boot into the Live Ubuntu system.

IMPORTANT: For Windows 8 pre-installed machine, you have to disable “fast startup” and “secure boot” features.

To disable “fast startup”, go to Control Panel > Hardware and Sound > Power Options > System Settings > Choose what the power buttons do and uncheck the Turn on fast startup box.

To disable “secure boot”, follow this screenshot tutorial.

3. Now you’re in the Ubuntu Live system. Plug in the 8GB+ USB stick. Then launch Gparted from the Unity Dash.

In the top-right drop-down box select the USB drive (16GB in my case), and you should see something like below:

I have two USB flash drives plugged in the computer, the Hard Disk is /dev/sda, 4GB Live USB is /dev/sdb, and the 16GB USB drive is /dev/sdc.

4. From the right-click context menu, un-mount partitions on the USB drive and then delete them.

Click the green check mark button to apply changes, finally you have an unallocated flash drive, like:

When done, close Gparted partition manager.

5. Click the desktop shortcut “Install Ubuntu” to bring up the Ubuntu installation wizard.

Follow the wizard until it asks you to choose where to install Ubuntu. Select the last option “Something else” and click Continue to bring up partition table.

6. In the partition table, scroll down and highlight the “free space” under the USB drive (/dev/sdc in the case) and click the plus sign to create below partitions one by one:

  • a FAT32 (or fat16) partition (required)
    • must be /dev/sdc1 (or sdX1)
    • mount point /NAME_HERE (/UDISK in the case)
    • set the memory size by yourself, it can be used for normal data storage.
    • leave others default.
  • a EXT4 partition for Ubuntu (required)
    • mount point “/” (without quotes)
    • memory size 5G+
    • leave others default.
  • a swap partition (optional).
    • You can skip this if RAM is large enough and you don’t need hibernation feature.

And very important is select install boot-loader to the USB flash drive (/dev/sdc in the case).

7. When everything’s done, click Install Now and confirm to format the partitions (Pay attention on which partitions to be formatted).

Click continue and finish the wizard. Once the installation complete, restart your computer and boot with the ‘Ubuntu To Go’ USB drive and enjoy!

Start your machine and when you’re at the Grub boot loader, select boot with the entry says something below. You may find it under “Advanced Options for Ubuntu” option:

Ubuntu, with Linux 3.x.x … (recovery mode)

If you don’t see the grub menu, press and hold the Shift key after you pressed the Power button to boot the computer.

2. In the Recovery Mode options list, select “root Drop to root shell prompt” and hit Enter. You should see the black and white command prompt at the end of the screen:

3. Now run below commands one by one:

  • First remount the file system with read & write permission: 
    mount -o rw,remount /
  • If you don’t remember the username, below command will show you: 
    ls /home
  • To change user password: 
    passwd USER_NAME_HERE

    Replace USER_NAME_HERE with your username. When it prompts, type in a new password and confirm.

The output “passwd: password updated successfully” means user password has been successfully reset.

Finally run command exit to back to menu (picture in step 2) and select “resume Resume normal boot” to exit Recovery Mode.
