Fedora 26 - test kernel .

You can test the kernel with your Fedora distro and get a funny badge of science:
Science (Kernel Tester I).
$ git clone https://git.fedorahosted.org/git/kernel-tests.git
$ cd kernel-tests
$ sh runtests.sh

This is my tests of Fedora 26 logs :
  • 4.14.0-0.rc1.git2.1.fc28.x86_64  FAIL logs
  • 4.13.0-0.rc7.git0.1.fc28.i686+PAE PASS logs
  • 4.14.0-0.rc1.git3.1.fc28.i686 PASS logs
  • 4.13.3-300.fc27.x86_64 FAIL logs
  • 4.13.3-300.fc27.i686+PAE PASS logs
  • 4.12.14-300.fc26.x86_64 PASS logs
  • 4.12.14-300.fc26.i686+PAE PASS logs

Fedora 26 : using Huion Giano WH1409 graphic tablet .

If you want to use your Huion Giano WH1409 graphic tablet with Fedora 26 then you need to use DKMS kernel.
Let's start. First you need to have a github account to download this kernel.
Use this commands to install the DKMS kernel from digimend.
$su 
#dnf install dkms git-core 
#git clone https://github.com/DIGImend/digimend-kernel-drivers.git /usr/src/digimend-6
#dkms build digimend/6
#dkms install digimend/6
Now connect the wireless USB dongle and reboot your computer. Take a look at dkms status:
dkms status
If you use VirtualBox then I tested with last version of VirtualBox and works without any settings.
If you want to set your tablet keys then you make custom X11 rules .
First is need to go to this folder: /usr/share/X11/xorg.conf.d/.
Now create 50-huion.conf file and use the configuration tool xsetwacom.
I don't make this settings because the tablet work's good with inkscape software.

Fedora 26 : Firefox Test Pilot send large files.

This tool from the Firefox team let you send you to upload and encrypt large files (up to 1GB) to share online.
This creates a link to pass along to whoever you want.
Each link created by Send will expire after 1 download or 24 hours, and all sent files will be automatically deleted from the Send server.
Also, the Firefox Test Pilot send does not require an add-on, and can be used in any modern browser.
See the next video from the official youtube channel.

Fedora 26 : Install Google Chrome.

Today I try to install Google Chrome on Fedora 26.
As you know this is one of the fastest and most well liked browsers available.
First I download of the rpm file into my Downloads folder and the I used dnf command to install into Fedora 26:
$ cd ~/Downloads
$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
$ su 
# dnf install google-chrome-stable_current_x86_64.rpm
The result, the Google Chrome browser is installed and run well.

Fedora 26 : reset root password .

Although most believe that they know the answer to this question then in Fedora 26 you have to adopt a method other than the classic one.
Start with select the boot line and press e key to edit.
Find the line with linux16 and add this on the end of this row:

rd.break
Press Ctr+x or F10 keys to reboot.
#mount | grep root
#mount -o remount,rw /sysroot
#mount | grep root
#chroot /sysroot/
#passwd root
...
#touch /.autorelabel
#exit
#reboot

Now you can use the new password for user root to login the system.
I try the old way with init=/bin/bash but I got a panic kernel ( maybe is the SELinux performs a complete file system relabel).
Anyway this solve my problem with reset the root password on Fedora 26 Server.

About rd.break, this interrupt the boot process before control is passed from initramfs to systemd.
The disadvantage of this method is that it requires more steps, includes having to edit the GRUB menu, and involves choosing between a possibly time consuming SELinux file relabel or changing the SELinux enforcing mode and then restoring the SELinux security context for /etc/shadow/ when the boot completes.

Fedora 26 server 64bit - tested VM.

I install Fedora 26 into simple way with the Netinstall Image (64-bit 484MB ) from here.
I used the last VirtualBox to test this Fedora 26 net image.
It took some time because the hardware used is without the dedicated video card and an I5 processor. The basic idea of this test was to see how to install it.
It's interesting to watch: the number of packages installed per time unit, the startup steps for the base installation and the work environment.
The other steps are more complex because it matters what you want to do with this linux. It depends on how much you want to adapt it to your hardware machine or whether you will make it a web server, ftp, sftp or a graphics rendering or video rendering station.
The total installation time in VirtualBox was one hour and seven minutes. The resulting video was modified by changing the number of frames for a faster viewing, (from 72 to 172).
The reason was the first steps to install Fedora not to set a specific linux server.
I use linux command under root account to install and set Fedora 26:
#dnf update 
#dnf upgrade 
#dnf grouplist 
#dnf grouplist -v
#dnf install @cinnamon-desktop
#dnf -y group install "Fedora Workstation"
#dnf install setroubleshoot
#sestatus
#sestatus -v
#getenforce
#dnf install clamtk
#echo "exec /usr/bin/cinnamon-session" >> ~/.xinitrc
#startx
Let's see the record video of this test install :
