Fedora 25 has Wayland enabled by default. However, if your computer has a (good) Nvidia graphic card and want to make use of it, you’ll need to switch to Xorg and install the Nvidia proprietary driver. Note that only the Nvidia driver with the version newer than 375.20 works on Fedora 25. Ref: How do I install the Nvidia driver on Fedora 25?
After I had my Fedora 24 upgraded to 25 on my desktop, ZFS no longer worked. I tried to remove zfs package and reinstalled; it didn’t work. Here’s how I got it working after trying many things. There could be a different way to fix it, though. Let’s check the version of the kernel: Check if spl, zfs are already installed: Manually install spl, dkms: Load zfs module: Voilla, I got ZFS working again....
I use ZFS as a storage driver for docker engine running on my machine. Today after my machine rebooted from a crash, yes Linux system crashes too, I notice that all my docker images and containers disappeared. First thing came to my mind was “did I accidentally destroy docker zfs data set last night?” It’s still there. At that point I suspected that Docker might no longer use ZFS as its data storage....
Every time there is a new release of Linux distro, I need to create a bootable USB. And, I forgot how I did it last time. So, I tried by using the “Startup Disk Creator” program installed on my Ubuntu workstation, only to find out that it didn’t even work. After a while I remember, it was just a matter of using dd command to copy the ISO image to the USB....
If you see a similar error message as the following when running Ansible on a Fedora 23 machines, there is an easy fix. It is very likely that a package “python2-dnf” is missing. This package is required for Python script to interact with DNF package manager. There is a good article available at fedoramagazine.org about running Ansible on Fedora 23. (I only found this later, and it’s very informative.)
After upgrading my VM running Fedora 23 beta to the release version, Gnome Desktop Manager (GDM) no longer started again. This is the same issue with newer version of xorg-x11-*, and it’s not yet supported by VirtualBox 5.0. I previously posted a quick fix by downgrading xorg-x11-* packages. To do that, I need to ssh into the VM. Here’s how we can find the IP address of running VMs. Let’s list the VMs available:...
I just finished upgrading Fedora 22 to Fedora 23 Beta and upon rebooting, gdm no longer started. I tried to reinstall the VirtualBox Guest Additions; unfortunately it still didn’t fix. To cut the story short, someone has given a working tip at this forum. The solution is to downgrade xorg-x11-server-Xorg package. After rebooting, I was able to login again.

While looking at the log file on my Raspberry Pi (running Fedora 20 Remix), I noticed that the date/time didn’t look right. EDT is a North American Eastern Daylight Time, which is 4 hours behind UTC. You can read more about it here. In my case, I prefer the time zone set to AEST (Australian Eastern Standard Time), which is 10 hour ahead of UTC. Here’s how it can be done....
This is just a quick note to remind myself how to enable or disable services using Systemd. In this example, I’m using denyhosts service. Check if a service is running. # systemctl status denyhosts denyhosts.service - SSH log watcher Loaded: loaded (/usr/lib/systemd/system/denyhosts.service; disabled) Active: inactive (dead) Start a service and verify its running status: # systemctl start denyhosts # systemctl status denyhosts denyhosts.service - SSH log watcher Loaded: loaded (/usr/lib/systemd/system/denyhosts.service; disabled) Active: active (running) since Thu 2014-07-17 01:44:29 EDT; 1min 25s ago Process: 15722 ExecStart=/usr/bin/denyhosts....
The Eclipse IDE that comes bundle with Android Development Tools (ADT) crashes when run on my laptop running Fedora. The error message which logged to console is: Fortunately, there’s a way to fix this problem by opening ‘eclipse.ini’ file, in my case: and added this line to the end of that file: Credit: Android – Solución Fatal Error del IDE Eclipse (ADT)
