I’m using Ubuntu 10.10 Maverick Meerkat and I had been having a problem related to sound. Every time I started the computer, the volume was muted and I had to un-mute it as well as increase the volume. When I searched for a solution, it was brought to my attention that Ubuntu 9.10 Karmic Koala and 10.04 Lucid Lynx also had this problem. I solved it by simply removing the buggy package alsa-utils which was responsible for this. Removing also-utils also removes ubuntu-desktop meta-package, but it does not matter since it is just a meta-package. To those who do not want to remove alsa-utils or ubuntu-desktop, some people in the Bug report have said that removing the line Continue Reading

I had posted about flash plugin controls not working in Ubuntu 9.10 Karmic Koala 64 bit here. I had moved to Ubuntu 32 bit for quite sometime and recently made a move back to Ubuntu 64 bit. I found the same problem with flash plugin controls in Ubuntu 64 bit. Sometimes it works, and sometimes it doesn’t. I haven’t found any specific patterns to when it does and when it doesn’t. If someone has, please do share.

GIMP 2.7.1 added Single Window Mode and GIMP 2.7.x can now be installed via PPA. It is available here for Jaunty, Karmic and Lucid. I have Ubuntu 10.04 Lucid Lynx installed and I installed GIMP 2.7.3 unstable. Here is how you can do it, but if you use it for production, you might want to wait for final stable release.

I was wondering if we could downgrade from Ubuntu 10.04 Lucid Lynx Alpha to Ubuntu 9.10 Karmic Koala. So I decided to put it upon test and I succeed. So, I am sharing this with those who wish to keep using stable Karmic Koala till the final version of Lucid is out.

Please note however, that all the installed applications will be lost, however the settings and files in your home directory will be preserved. So, for example if you have a huge list of saved sites on your Filezilla client, Filezilla will be gone, but when you install Filezilla on your Karmic, the settings should work. Also, your Firefox browsing history, preferences and other settings will also be preserved. Continue Reading

I am using globalmenu 0.7.9 (Mac OS X like Global menu for Gnome) from the globalmenu-team PPA (Karmic as Lucid is not available now) in my Ubuntu 10.04 Lucid Lynx. I get the following error on terminal when I try to launch any gtk applications from the terminal:

I am using balazan theme in Ubuntu 10.04 Lucid Lynx Alpha 4 from breathe ppa for Karmic Koala since Lucid PPA was not available when I started using Lucid. I saw this message when I launched gedit from terminal (gnome-terminal):

I am using Ubuntu 10.04 Lucid Lynx Alpha on a system with Gigabyte GA-G31M-S2L with Intel GMA 3100 onboard graphics. I upgraded to Lucid from Karmic Koala (9.10) and it was always showing these errors on boot:
“error: mountall Could not Connect to Plymouth”
“mountall main process (x) terminated with status 1″
Also, I could not experience Plymouth. I thought it was a problem with Plymouth and believed updates will fix it, but that did not happen till date. Today, I decided to fix it and went looking around for a fix and got it working.

As you know, Linuxmint is based on Ubuntu. So I thought, it might be possible to take Ubuntu as a base and turn it to Linuxmint with available Linuxmint software. Thats what I did.

I used Ubuntu Karmic Koala and turned it into Linuxmint Helena. You might use other Ubuntu base and turn it to respective Linuxmint distro, but you may need to follow different (yet similar) steps. Here is how I did it. Continue Reading
