  • Nice! Thank you for this.

  • Sir, I have problem with fedora 27 ; how to communicate with you ???

  • hello , what abouts using vmware on fedora and the typically problems with new kernels .

  • i got the Acpi error after installing a new kernel is there any solution?

  • Hi there. Updating the kernel on my linuxmint ruined my movie watching experience. Video quality became poor. What do I do?

  • can you help with vm setup with linux

  • Caveat about using Gnome Software to install updates: Gnome Software is a graphic user interface to see what software is available and already installed. I sometimes use it on my Fedora system. Soon after Fedora 27 was released, I decided to use it to install updates it notified me about. It has three tabs at the top, Available, Installed, and Updates. I have my /etc/dnf/dnf.conf number of kernels to keep set to 8, but I noticed that when I happened to once decide to install updates through gnome-software, instead of through dnf, after rebooting, it put removed all my old kernels I had saved and just had 3 in the list again. It ignored and overwrote my /etc/dnf/dnf.conf settings and put back the default 3 kernels, so I recommend always using dnf alone to update software.

  • Very useful. Major kernel updates is one of the best features in Fedora that I didn't find in any other distro (at least not as simple as in Fedora). Being an "above novice" Fedora user, the points shown in this video are exactly what I was looking for in order to have basic control over that feature. Thank you.

  • Nice. I think I want to save my pre-meltdown kennel. Lots of good info in here.

  • I was running into a problem with a few of my LInux boxes when the /boot partition basically filled up and it couldn't unpack and install the latest kernel. (I had gotten a bit lazy and wasn't cleaning up after myself). Here's a little Terminal routine I found to remove all but the latest kernels if you're running Ubuntu 16.04 or thereabouts:

    sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")

  • That's neat, but it's for Fedora; could you perhaps edit the title to reflect this, to save confusing newbies?

  • Ahh Mark you forgot point 9 – Switch the distro! Just kidding 🙂 Nice vid.
