With Hans' help, an old bug related to ACPI impacting majority of HP laptops running on any Linux distribution is finally resolved on both kernel 5.4.2 and 5.3.15. Some models may have an odd issue on boot like hp_wmi: query 0xd returned error 0x5 due to a too small buffer passing in for HPWMI_FEATURE2_QUERY. A fix is on the way for the next update and a test kernel from scratch-build is available (make sure to download first as the scratch build gets erased in a few days).

A year passed since owning HP Envy x360 15 2500u now running mainly on Fedora Design Suite now on its 31 release. The Design Suite is based on Fedora Workstation running on Gnome Wayland by default. The touchscreen works as intended and feel more responsive. Tweaking Firefox 70.0 However, due to a bug related to the GTK toolkit , using a stylus can cause crash on some applications. The fix is available and will be a matter of the time of an update . Sometimes, the touchscreen failed to work due to an issue related to ACPI only HP can address. The current workaround is to reboot the laptop. The LED Mute button works as intended with the help of a veteran SuSE developer. The quality of audio is adequate with seemly minimal loss  for a laptop once over-amplification is applied via Tweak application. At the time of writing, the majority of Ryzen APU powered laptop has yet to get the gyroscope function needed to auto-rotate the screen and other features like disabling keyboard o...

 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 displaye...

Thanks to the tips from Peter Hutterer , the author of libinput and libwacom , enabling the configuration of the stylus for the HP Envy x360 Convertible is very simple. Create a table file i.e. elan-264c.tablet in this example using this template and look at the dmesg output like: [    3.014612] input: ELAN0732:00 04F3:264C Pen as /devices/platform/AMDI0010:00/i2c-0/i2c-ELAN0732:00/0018:04F3:264C.0001/input/input15  Now the name is found as an ELAN device, include the following information # ELAN touchscreen/pen sensor present in the HP Envy x360 Convertible 15-cp0XXX  [Device]  Name=ELAN 264C  DeviceMatch=i2c:04f3:264c  Class=ISDV4  Width=14  Height=8  IntegratedIn=Display;System  [Features]  Stylus=true  Touch=true  Buttons=0 Copy the new created file to /usr/share/libwacom/ path. Gnome Shell will automatically detect the new tablet file and display the new information. Below is the...

Nearly one month later, HP Envy x360 Convertible 15  powered by Ryzen 2500U is running smoother on kernel 4.19.0 with someissues: The LED for the mute button failed to work suggesting a possible ACPI issue. An unfortunate oversight from HP for not including a led for Num Lock button.  The touchscreen function failed due to ACPI bug related to a mis-configuration of tables . Sadly, it affects all HP Envy touchscreen series equipped with AMD processors. Workaround made by an Arch user exists and no upstream Linux maintainers has picked up yet for clean up and improvment. The side effect would be an unfortunate false impression HP touchscreen with AMD processors is horrible. The gyroscope needed to automatically rotate the screen depending of the position is broken possibly due to ACPI bug. On the positive side, I was impressed by the modular adaptability  of HP Envy x360 upgrade wise thanks to the excellent HP documentation . The board can be replaced with the pow...

My ASUS X550ZE reached its end of life due to hardware power issue after getting a lot of abuse. From that experience, I have learned a lot about dual Radeon graphic processors working in the open source world and I followed AMD graphic development since then. Enter HP Envy x360 Convertible 15-cp0xxx Ryzen 5 marking the return to tablet PC. I originally intended to buy the Ryzen 7 version for more performance but the specification is very similar with only a sightly more powerful graphic processor as the difference on Ryzen 5. The model uses a 1 TB hard disk drive with 8 GB DDR4 RAM and I plan to upgrade to a 1TB solid state drive ( Samsung Evo version looks suitable). Installation  Installing Fedora 29 Beta Design Suite was very smooth after shrinking the partition of Windows 10 and keeping Secure Boot enabled by default. Post installation  Some revealing issues: Touchscreen and stylus mode is broken due to acpi bug preventing proper detection. AMD Raven, the...

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 ...
