Review of freshly installed Fedora 29 KDE Plasma Desktop (KDE GUI)

After the tutorial of Install Fedora 29 KDE Plasma Desktop this tutorial is mainly to see what to expect from a freshly installed Fedora 29 KDE Plasma Desktop – the look and feel of the new KDE GUI (version 5.13.5 of KDE Plasma).
Here you can find how to Install Fedora 29 KDE Plasma Desktop. Here it worth mentioning the included versions of KDE software for Fedora 29:
The Fedora 29 KDE Plasma Desktop comes with

  • KDE Plasma version: 5.13.5
  • KDE Frameworks version: 5.50.0
  • QT version: 5.11.1

The idea of this tutorial is just to see what to expect from Fedora 29 KDE Plasma – the look and feel of the GUI, the default installed programs and their look and how to do some basic steps with them, it is included also screenshots of the KDE settings program. Here you’ll find more than 140 screenshots and not so many text we do not want to turn this review of many text and version information and 3 meaningless screenshot, which you cannot see anything for the user interface, which these days is the primary goal of a Desktop system. You can expect more of this kind reviews in the future…

SCREENSHOT 1) Grub2 – Fedora 29 is selected by default.

The other Operating systems are Windows 10 and Ubuntu 16.04 LTS.

Install Fedora 29 KDE Plasma Desktop (KDE GUI)

This tutorial will show you the simple steps of installing a modern Linux Distribution Fedora 29 KDE Plasma Desktop with KDE for the user graphical interface. First we present the basic steps for installing the Operating system in addition to your present operating systems (here we have two: Windows 10 and Ubuntu 16) and then you can see some screenshots of the installed system and the look and feel of it. We have another tutorials showing more screenshots of the installed and working Fedora 29 (Gnome and KDE plasma) – so you can decide which of them to try first – coming soon.

The Fedora 29 KDE Plasma Desktop comes with

  • Xorg X server – 1.20.1
  • linux kernel – 4.18.16
  • KDE Plasma version: 5.13.5
  • KDE Frameworks version: 5.50.0
  • QT version: 5.11.1

The installation process is very similar to the old Install Fedora 27 KDE Plasma Desktop. Our system was pretty new – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 TI and the setup loaded successfully and there were no problems till the end.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/29/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-29-1.2.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

SCREENSHOT 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora KDE 29 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without beeing in UEFI mode.

How to compile xmr-stak (2.4.5) under Fedora 28 for CPU mining cryptocurrencies

Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability under Fedora 28, not all setups have a good video GPU, but you can have a decent CPU, which could be used to mine! For example AMD Ryzen Threadripper 1950X has a good performance on my crypto algorithms, even a better performance than the GPU mining.
Here we use AMD Ryzen Threadripper 1950X, which has 12 cores and 32 threads. Our setup is ASUS ROG ZENITH EXTREME (X399 Chipset) motherboard with 32G (4x8G CROSSHAIR VI HERO) DIMM DDR4 Synchronous Unbuffered (Unregistered) 2133 MHz (0.5 ns) and AMD Ryzen Threadripper 1950X. It can do 1253.5 cryptonight_v7 hashes per second.
Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:

Install NVIDIA official drivers on Fedora 28 (x86_64)

Fedora 28 comes with open source driver for NVIDIA cards, so you’ll get a decent and stable driver for your video, but without hardware acceleration and a machine not good for gaming like Steam, not good for scientific usage or crypt mining! In fact in recent open source versions (called nouveau) of the NVIDIA driver some cards got partial hardware acceleration, but most of the latest cards out there still need the proprietary driver!
Our test system is equipped with ASUS ROG Poseidon GeForce® GTX 1080 TI 11GB Platinum Edition by default here is the linux kernel output:

Here are the steps to install NVIDIA proprietary driver on Fedora 28:

STEP 1) Disable UEFI Secure Boot

Check in your BIOS if this feature is enabled. You should disabled it or after a successful installation of the kernel module you must sign it, which is not the goal of this howto. It is probably disabled if you use Linux, but it could be enabled if you use signed kernel, so it is good to check this settings because your driver won’t run if this feature is enabled.

STEP 2) Update your system and reboot. Then install the dependencies for the NVIDIA driver

DKMS is used for building the NVIDIA kernel module when a new kernel is installed. So you do not have to worry if you update your kernel. At first best way is to become root with sudo.

[myuser@localhost ~]$ sudo su
[root@localhost ~]$ dnf -y update
[root@localhost ~]$ reboot
[root@localhost ~]$ dnf -y install kernel-devel kernel-headers gcc dkms acpid libglvnd-glx libglvnd-opengl libglvnd-devel pkgconfig

STEP 3) Download the official NVIDIA installer application

Here is the NVIDIA search driver page – https://www.nvidia.com/Download/Find.aspx, just find the card you own and download the driver. Here are the steps we’d past:
So at the end you get a file NVIDIA-Linux-x86_64-390.67.run

[myuser@localhost ~]$ ls -al NVIDIA-Linux-x86_64-390.67.run 
-rw-r--r--. 1 myuser myuser 82272406  2 Jul  2,37 NVIDIA-Linux-x86_64-390.67.run

Select your video card and click on “Search”, we selected GeForce GTX 1080 Ti.

main menu
Select your video card

Click on the top driver, which is not “beta”.
main menu
Click on the driver to download

Infromation for the NVIDIA display driver. The most recent is version 390.67. Click on “Download”.
main menu
Click on download

Click on download again to begin downloading the installation file. You can download NVIDIA End User License Agreement, too.
main menu
Click on download again to begin downloading the installation file.

STEP 4) Disable the open source nouveau.

The driver must be blacklisted on two places, when the initramfs loads and during the fedora 28 systemd booting. So first put the following in

/etc/modprobe.d/blacklist.conf

[root@localhost ~]$ echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

and in file

/etc/sysconfig/grub

add at the end of the line starting with GRUB_CMDLINE_LINUX the following:

rd.driver.blacklist=nouveau

so in our case we have:

GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora_localhost--live-swap rd.lvm.lv=fedora_localhost-live/root rd.lvm.lv=fedora_localhost-live/swap rhgb quiet rd.driver.blacklist=nouveau"

This is just an example, do not copy the whole line, just add at the end before the ending quotes rd.driver.blacklist=nouveau

STEP 5) Update grub configuration and remove the open source driver from x11 and initram

[root@localhost ~]# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

As you can see the grub configuration tool found two more operating systems Microsoft Windows 10 and Ubuntu 16 and they are saved in the new configuration, so it is safe to make the new configuration it will preserve the other grub configuration and you’ll be able to boot them if you choose it from the grub menu.
We removed the unnecessary package xorg-x11-drv-nouveau.x86_64, regenerated the initramfs for our kernel and instructed the system to set the default console login – you do not need GUI and you won’t have it (you’ve just removed the GPU driver!) the next time you boot your machine.

STEP 6) Run the NVIDIA installation file from root user

After the restart your system won’t boot in GUI, there will be the login console prompt:

main menu
Console login

Login with your user and then become root, the installation need to be executed by the root user. Then execute NVIDIA-Linux-x86_64-390.67.run, but before you must change the permissions to executable.

[myuser@localhost myuser]# chmod 755 ./NVIDIA-Linux-x86_64-390.67.run
[myuser@localhost myuser]# sudo su
[root@localhost myuser]# ./NVIDIA-Linux-x86_64-390.67.run

vainfo – VA-API driver, the video acceleration API driver

Here is the nouveau – as you can see no acceleration supported:

[myuser@localhost ~]$ vainfo 
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/nouveau_drv_video.so
libva info: Found init function __vaDriverInit_1_1
libva info: va_openDriver() returns 0

vainfo: Driver version: mesa gallium vaapi
vainfo: Supported profile and entrypoints
      VAProfileNone                   : VAEntrypointVideoProc

And here is after installing the NVIDIA proprietary driver, you get video acceleration for your video player!

Review of freshly installed Fedora 27 Cinnamon Desktop

After the tutorial of Install Fedora 27 Cinnamon Desktop this tutorial is mainly to see what to expect from a freshly installed Fedora 27 Cinnamon – the look and feel of the Cinnamon GUI – http://developer.linuxmint.com/projects/cinnamon-projects.html
The idea of this tutorial is just to see what to expect from Fedora 27 Cinnamonthe look and feel of the GUI, the default installed programs and their look and how to do some basic steps with them, it is included also screenshots of the Cinnamon settings programs. Here you’ll find more than 100 screenshots and not so many text we do not want to turn this review of many text and version information and 3 meaningless screenshot, which you cannot see anything for the user interface, which these days is the primary goal of a Desktop system. You can expect more of this kind reviews in the future…
Cinnamon derives from GNOME 3 and it follows the traditional desktop conventions. After the release of GNOME 3 and GNOME Shell (and abandoning GNOME 2) a fork of GNOME 3 was made and Cinnamon was born to follow traditional desktop not the “shell” interface of GNOME 3. At present Cinnamon is not a front-end on top of the GNOME any more despite it still uses GTK+. If you search for a GTK+ based GNOME 2 or xfce similar linux desktop GUI you might reach a good option with Cinnamon. Its look and feel is more like KDE than MATE, which follows more strictly GNOME 2 layout.
Cinnamon is developed by Linux Mint team, which is yet another Linux distro.You can check it here – https://linuxmint.com/ As you may see from the screenshots below the main idea is to have a taskbar situated bottom of the screen with a “start” button and all programs arranged in different categories – the traditional Desktop behavior. The desktop feels fast, but there are reports of using greater memory footprint.

Install Fedora 27 Cinnamon Desktop

This tutorial will show you the simple steps of installing a modern Linux Distribution like Fedora 27 Cinnamon for the user graphical interface. Cinnamon derives from GNOME 3 and it follows the traditional desktop conventions. After the release of GNOME 3 and GNOME Shell (and abandoning GNOME 2) a fork of GNOME 3 was made and Cinnamon was born to follow traditional desktop not the “shell” interface of GNOME 3. At present Cinnamon is not a front-end on top of the GNOME any more despite it still uses GTK+. If you search for a GTK+ based GNOME 2 or xfce similar linux desktop GUI you might reach a good option with Cinnamon. Its look and feel is more like KDE than MATE, which follows more strictly GNOME 2 layout.
First we present the basic steps for installing the Operating system in addition to your present operating systems (here we have two: Windows 10 and Ubuntu) and then you can see some screenshots of the installed system and the look and feel of it. We have another tutorials showing more screenshots of the installed and working Fedora 27 Cinnamon (Gnome and KDE plasma) – so you can decide which of them to try first – coming soon. All of the installation setups are very similar for all GUIs of Fedora 27 it loads a live edition of the version of Fedora 27 you install and then the setup is launched by the user, the setup almost identical in all editions, but we do not want to give you a tutorials with “spaghetti” and unstructured flow of steps to follow.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/27/Spins/x86_64/iso/Fedora-Cinnamon-Live-x86_64-27-1.6.iso

It is a LIVE image so you can try it before installing. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

STEP 1) If you booted from the DVD you would get this first screen – select “Start Fedora-Cinnamon-Live 27” and hit Enter

Start Fedora-Cinnamon-Live 27
