Touchscreen and stylus now working on HP Envy x360

The Fedora version on kernel 4.19.3 includes a patch allowing both stylus and touchscreen to properly run on AMD processor based HP touchscreen thanks to the combined effort from Hans, Lukas and Marc for finding the root cause and testing the fix.

A few scary moment on HP Envy x360 15-cp0xxx Ryzen 2500U was a conflicting IRQ handling due to possibly booting on Windows 10 used to get all feature parity to Linx counterpart i.e. Fedora 29 in this case. Fortunately, power off somewhat did the trick. Since then, both stylus and touchscreen run without a hitch.

A minor issue was the Gnome Settings does not display information of both devices due to the missing data from Elan driver thus meaning no configuration possible like assigning buttons and no possible way to test touchscreen. Additionally, Gnome Shell assumed the battery still at 1% capacity and the bug is filed for that reason.

Detected Stylus displayed with incorrect battery status

Nevertheless, the stylus with some configurating runs smooth on applications like Gimp and Inkscape. For the touchscreen, Firefox for Linux lack proper onscreen keyboard. That will be continued...

Getting ready for Vanlug

Busy weekend. I just took a break for making a presentation of Fedora Core 6 and Fedora Project for Vancouver Linux Users Group which will debut on November 20, 2006. A local computer store was kind enough to give me a laptop for the demonstration of Fedora Core 6 (Zod) live spin and Sugar interface from OLPC Project. Should you be interested to view that event and live near Vancouver, here is the address .

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
