A Fedora Core 5 i386 on Athlon64 3200+

Writing this blog on a brand new motherboard Gibabyte GA-K8NSC-939 with Athlon64 3200+ Venice. It is much snappier than the old Athlon XP2500+ Barton. That motherboard is not equipped with on-board which is not a big deal. That costs $310 CAN which is a bargain for its category. I am planning to get a SATA hard drive to install x86_64 rawhide version of Fedora Core this.

En passant, je salue la communauté de Fedora France.

Drawing hair with Inkscape

My very first online tutorial is an adaption from Chris Design Drawing Hairs article using both Path and Path Editor tools which requires Inkscape 0.47 or newer. Start-up Inkscape application which should open a new blank page and set the document into landscape. Create a path Select the bezier tool or press either Shift+F6 or B on the keyboard. Draw a line to approximately 800px or more. You can also use rectangle tool ( R or F4 as shortcut key) as a thin line illustrated in grey. While the line is selected, convert into path from the menu Path -> Stroke to Path or press Ctrl+Alt+C on the keyboard. For the rectangle, Path -> Object to Path or Ctrl+Shift+C . The result will show grey diamonds on each corner. Create a pattern On the menu, Extensions -> Modify Paths -> Add Nodes . Set the Max Segments Length to 5px. On the menu Extension -> Modify Paths -> Jitter Nodes . Leave the default settings and apply effects.

HP, Linux and ACPI

Majority of HP hardware running on Linux and even Microsoft reported an issue related to a non-standard compliant ACPI. Notable message below repeats at least three times on the boot: 4.876549] ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D128] at bit offset/length 128/1024 exceeds size of target Buffer (160 bits) (20190215/dsopcode-198) [ 4.876555] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529) [ 4.876562] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_BUFFER_LIMIT) (20190215/psparse-529) The bug is a known for years from which Linux kernel team are unable to fix without the help of vendor i.e. HP. Here is a compilation of reports: BIOS error: The BIOS in this system is not fully ACPI compliant. ACPI BIOS ERROR (blue screen) on startup ACPI bad works with Linux The good news is some errors seems harmless. Unfortunately, such errors displayed the quirks approach used by

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
