Hi , Let’s say I want to uninstall a package in centos. I used yum remove command and it shows the package are removed . However, I still see the files are there. So I understand that uninstalling does not remove the package and files together the way we uninstall in windows. Is that correct?
Sorry if my question is too naive, I am a newbie.

First off hello forum, I have not installed Linux so I’m newer than a newbie.

Even though I would love to break free from the shackles of Windows I just can’t see a way forward with linux. The biggest issue I have is I use ableton 10 suite (DAW) which is not supported in Linux. Also as far as I can see…

I’m a 15 year old male with Asperger’s Syndrome. I have been interested in computers/tech since I was 5 years old.

Mine was 8 or 9 years ago when Ubuntu 10.10 was still a fresh new release. Back then I was a member of the Bill Gates’ satanic sect. A forum admin suggested that I tried Linux. And I did, starting with Ubuntu 10.10. Tried many different distros but almost all of them had one major problem – showing my main drive (where my music and files are located) as a “Picture CD” and thus I was unable to write on that drive. No possible solutions seemed to help, so I returned to Ubuntu. Sadly, it took…

For quite some time I have this problem with all movies and all video players – when the characters of a movie speak, the sound is often so quiet that I can hardly hear what they say and I have to increase the sound volume.

So basically, I shrank my Windows partition to try and expand the Ubuntu partition. However, in spite of my Ubuntu partition not being mounted, it just won’t let me give it any of the unallocated space. It clearly says it is unmounted (I launched GParted from an Ubuntu LiveUSB), it will let me shrink it, but not expand it. It is just as though the unallocated space didn’t exist and the maximum size of the partition was fixed.

Any ideas?

Thank you very much.

This is a simple instruction for newbies about how to fix problem with the sound on Linux, like missing sound from any application, weird static noise from the speakers, or even noise from the microphone when the environment around it is perfectly quiet. I’ve done this in Mint but as far as I know it should work with all distros.

1. Open terminal.
2. Type

and press enter. This will kill the audio service and the icon from the bottom right corner will disappear….
