Ubuntu Graphics Session Fix after botched Kernel Upgrade

Overview
This post is about restoring graphics to your Linux Desktop session if you install some kernel updates that dont go so well. Particularly, ones that fail with your graphics drivers.

Quick Steps
If you get error message (when trying to upgrade kernel packages or kernel drivers): "Skipping (driver build) at this time because kernel-source is missing." Try the following steps:

Note: `uname -r` is a commandline option which will auto-substitute your kernel version and architecture into the install command. If installing via a GUI, just use the info output from running the console command `uname -r`.

sudo apt-get install linux-source-`uname -r` linux-headers-`uname -r`

If this does not automatically cause your nvidia drivers to compile, cause a manual install with:

sudo apt-get install nvidia-current

If that still doesnt work, try uninstalling and reinstalling nvidia-current.

Background
Today I noticed there were some kernel updates in Ubuntu, but they had been kept back. So I decided to manually install them, since they did not appear to be causing any package conflicts. I do updates from command line with apt-get (because Im awesome that way *wink*). While installing the held-back packages, being kernel updates, it tried to accommodate my Nvidia graphics drivers.

Apparently, this failed. I noticed the error on the console, and immediately downgraded my kernel back to the previous versions. But alas, it did no good. I rebooted and was confronted with a text-only machine. Now, Im fine with this, since I spend a lot of time on console. (Screen, vim, ssh, and elinks are usually all I need for most rescue operations. Sometimes rtorrent, wget, and curl are handy too.)

After trying to get the packages to jive well together, I gave up trying to juggle the kernel packages and instead focused on the Nvidia drivers. I tried installing the nvidia-current package provided by the Ubuntu repositories. (I was running a later version from a PPA.). This failed, but triggered the same error.

"Skipping (driver build) at this time because kernel-source is missing." Now, Ive seen this error before. So I quickly installed the linux-source-`uname -r` package. This did not quite do the trick, and I have been around long enough to know that the source-packages often require the header packages as well. So I install linux-headers-`uname -r` package.

Once installed that, I didnt even have to do anything. The system automatically compiled the missing nvidia drivers and installed them for me. A quick reboot later, and now I am blogging about this simple solution.

Ubuntu 11 04 Upgrade Linux Kernel to 2 6 39 0

Its been quite some time since Ubuntu released its 11.04 OS, even long before its stable release Natty Narwhals Alpha release had gone through some intense debates regarding its unity interface.
Despite the fact that Ubuntu is the most stable and user-friendly OS in the Linux family, its latest release of Natty Narwhal has left many Ubuntuans skeptical about upgrading from Ubuntu 10.10 , due to the fear of new unity interface and some known bugs.

I recently had some issues with Natty too, while using Gimp and Blender the screen just froze on me for no reason, it was very weird and was nothing like the Ubuntu Ive known form its 8.04 release.

When I spent some time on Natty Narwhals release notes I found that it has a lot of known issues, one line under Graphics and display says:
On certain systems, a bad interaction between Unity, the GL driver and the kernel may cause the system to hang. (740126)

This is a frequent screen frozen issue, and it�s believed to have something to do with the kernel. In Ubuntu 11.04, the default Linux kernel version is 2.6.38-8. Considering the release notes bugs and the suggestions I received from users on launchpad.net I upgraded my Ubuntu kernel to 2.6.39-0, and that seems to have done the trick, all my applications now are stable and never freeze or hang.

If you consider upgrading your kernel to 2.6.39-0, here�s how you could do it.

Run these following commands in the terminal(Ctrl+Alt+T)

1.) Add the kernel ppa and update your system:

sudo add-apt-repository ppa:kernel-ppa/ppa

sudo apt-get update

2.) Check available kernels with the command:

apt-cache showpkg linux-headers

  kernel 2.6.39.0 should be in list.

3.) Run the command to install kernel 2.6.39.0:

sudo apt-get install linux-headers-2.6.39-0 linux-headers-2.6.39-0-generic linux-image-2.6.39-0-generic --fix-missing

And finally restart your computer, goto system monitor and check your systems kernel version.

------------------------------------------------------------------------------------------------------------------------------------------------------
Note: If you are doing this on virtual-box, after system restart you will be thrown back into Ubuntu Classic interface.To restore your system back into Unity interface you will have to reinstall guest additions and kill the gnome-settings-daemon, here are some commands that will help you do this.

(Only for Users upgrading on Virtual-box)

sudo apt-get update

sudo apt-get install virtualbox-ose-guest-utils

killall -9 gnome-settings-daemon && gnome-settings-daemon

and restart your guest OS.

Ubuntu 12 04 Upgrade SVN 1 7 9

Today I rolled back my distro from Ubuntu 13.04 to 12.04. This is because I was sick of all the stability/general-problems with Compiz, and I know they worked perfectly in 12.04. However this meant that my svn version was incompatible with all the code I had previously checked out. Rather than re-check out all the repos again, it is better to just upgrade svn as no doubt it has some new features/fixes as well.

If you are using Ubuntu 14.04, then ignore this tutorial.

Steps

Install this SVN PPA and upgrade (assuming you have already installed the subversion package).

sudo apt-add-repository ppa:svn/ppa -y
sudo apt-get update && sudo apt-get dist-upgrade -y

For those running RabbitVCS. I highly recommend that you reboot at this point as the nautilus extension would not work for me until I did this (even after performing a killall nautilus). If it still does not work, try performing these:

sudo ln -s /usr/lib/x86_64-linux-gnu/libsvn_client-1.so.1.0.0 /usr/lib/
sudo ln -s /usr/lib/x86_64-linux-gnu/libsvn_client-1.so.1 /usr/lib/
sudo ln -sf /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 /usr/lib/
sudo ln -sf /usr/lib/x86_64-linux-gnu/libpython2.7.so.1 /usr/lib/

It is working for me now after performing these, but as I did not try rebooting until afterwards, I am not sure if all/any of them are actually necessary.

Ubuntu 14 04 is a solid upgrade

I installed the latest Ubuntu 14.04 and its variants (Gnome, Xubuntu, Lubuntu) and have chosen the regular desktop as the best new solution to my preference for a traditional Gnome look and feel. Using the GNOME Flashback Session with Compiz, gets you back to this desktop with little trouble. From there I installed Synaptic, the Nemo File Manager (better than Nautilus), Pidgin, Chrome, Docky, Deluge, Audacious, Yarock, Gnome Tweak Tool, Ubuntu Tweak, Unity Tweak Tool (needed to move buttons to the right), Screenlets, and Greybird and Elementary icon themes. I tried a number of music players including Banshee, gmusicBrowser, Deadbeef, Clementine, Rythmbox, Yarock, and Audacious. It is very snappy and has a faster boot time than my old Ubuntu 12.10 build. The Ubuntu Gnome version was also good, but did not allow me to edit the top & bottom toolbars. Overall a very good news for us all. Below are my screen shots and a link where to get the files. Enjoy.
