Fedora 36 : Fill out this survey for a badge.

I've always liked Fedora distro because it applies a concept of interactivity between developers and users.
Even if not everything works, you can see the progress made from the older versions.
Today I completed my feedback in a survey requested by them and I also got a small badget for my effort.
You can find it on this webpage.

Fedora 36 : Inkscape 1.2 with Huion WH 1409 graphic tablet.

In this tutorial I will show you how to install and use the Huion WH 1409 graphics tablet with the new release of Inkscape 1.2 software.
You will need to use the DKMS feature of the kernel and the tablet-specific drivers.
Let's start with the following command to get the driver and show the files:
[root@fedora mythcat]# git clone
Cloning into 'digimend-kernel-drivers'...

[root@fedora mythcat]# cd digimend-kernel-drivers/
[root@fedora digimend-kernel-drivers]# dir
compat.h    dracut.conf        hid-uclogic-params.c
COPYING        hid-ids.h        hid-uclogic-params.h  udev.rules
debian        hid-kye.c        hid-uclogic-rdesc.c   usbhid
depmod.conf    hid-polostar.c        hid-uclogic-rdesc.h   xorg.conf
digimend-debug    hid-rebind        hid-viewsonic.c
dkms.conf    hid-uclogic-core.c  Makefile
Let's create it using the command
[root@fedora digimend-kernel-drivers]# make dkms_install

dkms add .
Creating symlink /var/lib/dkms/digimend/11/source -> /usr/src/digimend-11
dkms build digimend/11

Building module:
cleaning build area...
make -j1 KERNELRELEASE=5.17.9-300.fc36.x86_64 KVERSION=5.17.9-300.fc36.x86_64...
Let's check and reboot.
[root@fedora digimend-kernel-drivers]# dkms status
digimend/11, 5.17.9-300.fc36.x86_64, x86_64: installed (original_module exists)
[root@fedora digimend-kernel-drivers]# reboot
After rebooting the diver must be activated and you will see that Linux responds to the movement of the tablet pen.
[root@fedora mythcat]# modprobe -r hid-kye hid-uclogic hid-viewsonic
Install the latest version of inkscape 1.2 using the DNF utility.
Start the inkscape software:
[mythcat@fedora ~]$ inkscape
static bool Inkscape::UI::Dialog::DialogContainer::recreate_dialogs_from_state(InkscapeWindow*, const Glib::KeyFile*): Key
file does not have group “Windows”
Gdk-Message: 15:09:10.534: Error flushing display: Broken pipe
It seems that inkscape does not detect and set the tablet if you use the settings of this software, but you can use the tablet with this software even if you do not set it.

News: Fedora 36 beta released.

Fedora 36 beta was released and I tested it today.
First of all, Fedora 36 is still in pre-release mode and you should be careful to back up your data before upgrading it has a rollback option just in case.
I haven't seen any significant differences in browsing, and overall it seems faster.
The upgrade commands are the same but the installation process seems more complex.
# dnf upgrade --refresh
# dnf autoremove
# dnf install dnf-plugin-system-upgrade -y
# dnf system-upgrade download --releasever=36 --allowerasing
# dnf system-upgrade reboot
# cat /etc/os-release 
Let's fix the install process:
# dnf system-upgrade clean
# symlinks -r -d /usr 
This is ascreenshot take on my HP Compaq 6710b laptop, you can see the Workstation Edition Prerelease.
