Installing Google Chrome 64bit on Ubuntu Quantal Quetzal

Installing Google Chrome on the 64bit Quantal Quetzal is pretty simple.

When you navigate to google.com from the installed Firefox browser, on the right is an "Install google Chrome" link.

Click on it and it goes to a downloads page. Click the "Download Chrome" link, it automatically detects "For Linux (Debian/Ubuntu/Fedora/openSUSE)".

At the next page, select 64 bit .deb (For Debian/Ubuntu) and click the button to proceed.

It will prompt to download google-chrome-stable_current_amd64.deb .

When the download is complete, find it in your downloads folder using the file browser and launch it.

The Ubuntu Software Centre starts and will bring up the Google Chrome page.

Select the "install" button, authenticate with your password and Google Chrome is installed.

Installing The Latest Nvidia Drivers on a W520

The Nouveau drivers installed by default for Quantal Quetzal on the ThinkPad W520 are not good enough. Most significantly, the display would be garbage when opening the lid after sleeping. The only solution would be to Ctrl+Alt+F1 to get a console, log in and reboot.

A source to Install and Configure Latest Nvidia Drivers in Ubuntu 12.10 Quantal indicates to simply run the following:

% sudo apt-get install linux-source
% sudo apt-get install linux
% sudo apt-add-repository ppa:noobslab/nvidia-quantal
% sudo apt-get update
% sudo apt-get install nvidia-current


After a reboot, closing to sleep and opening again correctly restores the system to a screen saver.

Brightness Adjustment hangs the W520

During debugging this afternoon, doing a Fn+Home or Fn+End to adjust the display brightness caused the ThinkPad W520 to hang. I had to power cycle to resolve.

One of the notes I found [SOLVED] Brightness Adjust Does Not Work says to add the nvidia-specific EnableBrightnessControl=1 option in xorg.conf .

I have found that once I updated the BIOS on my W520, the problem is not occurring right now on my Quantal Quetzal install.

Cannot Boot Quantal Quetzal on W520 solved by noapic

One of the reasons I never updated to Precise Pangolin was because I could not boot off the Live CD. A fix was supposed to forthcoming from what I read but I never tested anything newer.

When Quantal Quetzal came out the 64Bit Live CD has the exact same problem. When booting from the CD, the screen goes blank and after a minute or so the screen shows some error messages but Ubuntu does not boot.

Seems like this is a common problem with RedHat and previous Ubuntu releases .

The latest BIOS update installed today also did no good.

From reading Tech Notes about the graphics settings, running Discrete Graphics with Nvidia Optimus Mode disabled continues to be the correct option, as I had set with Oneiric Ocelot.

I also have all virtualization settings enabled in BIOS.

The best (only) way to boot from the Live CD is to enable the "noapic" option. You need to boot from the CD and hit a key are the purple screen when the keyboard shows up. After selecting the language, you can hit F6 to select the "noapic" option.

After installing Quantal Quetzal 12.10 64Bit, I needed to add the 'noapic' option to the kernel boot line.

To do this:

1) edit the /etc/default/grub file and change the GRUB_CMDLINE_LINUX line to add
GRUB_CMDLINE_LINUX="noapic"
2) run sudo update-grub to update the grub configuration.

Once doing that the issue is solved.


First Post: Why a Ubuntu Blog?

I have been a UNIX user since 1985 and a Ubuntu user since Edgy Eft in 2006. I am a Microsoft Windows hater so have run Linux on my various ThinkPads as long as it has been possible.

Once of the "problems" with Linux is that it takes quite a bit of "hands on" maintenance to get things working just right. Rather than using system update, I have found it also works better to do a fresh install with each new Ubuntu release.

I have been running Oneiric Ocelot for quite some time and I skipped a release waiting to install a 64bit Ubuntu on my Lenovo ThinkPad W520. Now that it has been more than a year running on 11.10, I have found it difficult to remember all the things I did to get the release running the way I wanted.

So now that I am installing Quantal Quetzal, I thought it a good idea to actually record all the little tweaks I need to do to get the system running. It will be a good reference when moving to the next release.
