Solving networked scanner issue on HP all-in-one printers

Looking and talking at Ask Fedora, it will be nice to share suggestion for proper networked scanner support on HP all-in-one printers. One of solution is to install hplip-gui via terminal.
sudo dnf install hplip-gui
Or
su -c "dnf install hplip-gui
Unfortunately, the frontend is not listed on Gnome Software due to appdata missing.

Another solution is to directly edit /etc/cups/printers.conf and change the device URI. To find the correct URI with HP protocol  of your networked HP all-in-one printer, use hp-setup -i or hp-setup hostname. The URI should be listed like
hp:/net/name_of_hp_printer?zc=hostname
Where hp:/net/ is the protocol replacing dnssd://, zc=hostname is the name of hostmane for the all-in-one printer sometime subsituted by ip=ipaddress

For example, the uri of Photosmart eStation C510 is 
hp:/net/Photosmart_eStn_C510_series?zc=HPFFBBC9
hp:/Photosmart_eStn_C510_series?ip=192.168.1.64
Save the change and restart either the system or simply type sudo systemctl restart cups.

You should be able to run a networked scanner with your favourite scanner application like simple-scan. The reason of the process is due to a bug from hplip that failed to assign the hp:/net protocol to their own printer. Hopefull HP will fix the problem in the incoming future.

Using AMD RX Vega driver OpenCL on Fedora 29

The Raven Ridge APU is very capable processor to handle OpenCL inside some applications like Blender, Darktable and Gimp. Unfortunately, the current implementation from Mesa, clover, stuck to 1.3, is not supported. AMD released their driver 18.40 with OpenCL2.0+ targeting only Red Hat Enterprise Linux/Cent OS 6.10 and 7.5 in addition of Ubuntu LTS. The good new is the former rpm format can be used on Fedora. The graphical part of Raven Ridge is Vega 8, basically a cut-down of Vega56 or Vega64 meaning choosing either driver for RX Vega . The instruction is provided for extracting the rpm files but here is  some requirements for OpenCL: kernel-devel (provided by Fedora repository) amdgpu-dkms dkms libopencl-amdgpu-pro opencl-amdgpu-pro-icd Once done, applications needing OpenCL will automatically detect the driver located on /opt/amdgpu/lib64 . Blender will list as unknown AMD GPU and Darktable will enable it. OpenCL from official AMD driver enabled on Darktable ...

Detailing the installation of AMD OpenCL rpm for Fedora

Revisiting the previous blog and freshly reinstalling Fedora Design Suite due to a busted boot, I look at the official guideline from AMD Driver for Red Hat Enterprise Linux 7.2 and write a way to improve the process of installing on Fedora 29 in this example. Extracting the tarball contains the following: amdgpu-install amdgpu-pro-install symlink to amdgpu doc folder repodata folder RPMS folder containing rpm package Executing the command ./amdgpu-install -opencl=pal --headless sadly failed on Fedora on that line: ./amdgpu-install -y --opencl=pal --headless Last metadata expiration check: 0:30:51 ago on Mon 19 Nov 2018 07:13:43 PM PST. No match for argument: amdgpu Upon closer look, the script failed to created a temporary repository on /var/opt/amdgpu-pro-local probably explaining why amdgpu metapackage name failed to display. Someone should investigate and provide a fix. At least, we find out Fedora support is available but unofficial. Due to its design, Gnome ...
