Ubuntu

This is my third time having problem installing Nvidia drivers on Ubuntu (14.04). What’s worse is that I could not remember how I fixed them last time. Hope this blog post will prevent me from pulling my hair out for the 4th time. So, I installed Nvidia driver as usual: After it’s finished, I tried to load the module: Well, it turned out that I need to also install another linux-image package: linux-image-extra-3....

As of today, Code Composer Studio (ccs) 6 is only available for 32-bit Linux platform. The good news is that it can be installed on a 64-bit version of Ubuntu and Fedora. In this blog post, I’m going to show a few issues I came across and how to fix them on Ubuntu 14.10 64-bit. Issue 1: After the installation, when I ran the ccs, it produces some warning and error messages then quit....

On Ubuntu distro, if you see the error message in console as the following whenever you run a Gnome-based applications, chances are you had ‘overlay-scrollbar’ package previously installed but now removed. However, the configuration file which came with that package remained on your system. We can verify this with this command: rc : remove but config file still presents. On my Ubuntu desktop, this config file resides at /etc/X11/Xsession.d/81overlay-scrollbar. To correct this problem, we can purge ‘overlay-scrollbar’ package with this command:...

The real tag line for moserial is “a serial terminal for the GNOME desktop”. However, since it’s installed just fine on my KDE desktop, I titled this post as “moserial - a serial terminal for Linux”. (Well, it probably works on servers as well, not just desktop.) So what is this moserial? It’s a terminal which allows you to connect to view or send data to a serial port. For example, a lot of mbed device or micro controllers, such as Arduino, can be configured to send/receive data via serial port....

At my current work place, we use Puppet to manage desktop machines. Recently, I need to prepare an new image based on Ubuntu 14.04 LTS. To prepare an image, in brief, first thing is to install a fresh Ubuntu on a machine, compile and package lots of applications, and make change to configuration such as look and feels, etc. As mentioned earlier, I use Puppet to manage machine, so I store all customed configuration on the Puppet server....

When I tried to update an Ubuntu (12.04) machine with the usual apt-get command, this error message came up: Reading this post (http://ubuntuforums.org/showthread.php?t=2045321), one way to fix it is to download liapt-pkg4.12 and re-install it: This seems did the trick.

On Kubuntu 11.10, we have KsCD program installed to play audio CD. The problem I’m having is that some machines could play audio cd and some couldn’t. All machines run Kubuntu 11.10. To fix this issue, check that /dev/cdrom is a sym link to /dev/sr0 (credit [1]). In my case, machines which couldn’t play audio CD don’t have ‘/dev/cdrom’: # ls -l /dev/cd* ls: cannot access /dev/cd*: No such file or directory Let’s create one:...
