Linux/KDE Plasma: 
(available in About System)

ADDITIONAL INFORMATION
older versions of Krita seem to be the only ones to support the pen eraser feature. Please fix it since many of us rely on this feature since it feel natural to artist that switched from traditional to digital.
Comment 1 Phil 2022-01-03 09:34:34 UTC 
Same with good old Cintiq13HD on macOS 11.2
Comment 2 Know Zero 2022-01-24 08:07:46 UTC 
I can confirm this bug on my old Wacom Graphics with both KDE OpenSuse and Linux Mint. 

Krita 4.4.8 appimage works, but 5.0.2 does not.
Comment 3 Alvin Wong 2022-01-27 09:39:00 UTC 
Can reproduce with SP2017 on Windows 10 but only when using WinTab. Tablet log shows both pen tip and eraser tip as "Stylus".

Using WinInk, tablet log correctly shows "Eraser" for the eraser tip.
Comment 4 Ahab Greybeard 2022-02-08 11:27:20 UTC 
With my old Wacom Graphire 2 tablet on Linux, Debian 10, using the 4.4.8 appimage or the 5.0.2 appimage, I have no problems using the 'eraser end' or the 'pen end' of the stylus then selecting different brush presets with each of them.
I can't test this on Windows because there is no Windows 10 driver for it and the modern Wacom Control Centre refuses to recognise it as a valid graphics tablet.

With my Wacom Intuos Draw tablet on Linux, I can't test it because I don't have the facilities to change the Linux driver configuration.

With my Wacom Intuous Draw tablet on Windows 10, 4.4.8 and 5.0.2 recognise and use the 'eraser' setting if I configure the second button to 'Erase' with the Wacom utility and also use Windows Ink.
This does not work with Wintab.
That Erase setting is not a toggle, the button has to be held down to use the 'eraser mode' preset.

Fix name of default eraser preset

In commit 90afcc73f065610e32610325fd89ce03d4272f72, Halla removed the
eraser name lookup and fallback. However, the default name lacks the
"a)_" and thus doesn't match any default resource.

Fix default preset names (master branch only)

Commit 88e48c58ed576b946dbc49ce0fa00e2dcb24afbd causes default
preset lookups to fail, since we replace all underscores in preset
names.

This commits completes dd368ef73f3bf8972a16fa0b0c4fd5f193ba6fa1
by applying the replacement to the hardcoded default names.
