Has any man-made satellite or space vehicle ever been hit by a natural meteoroid?

For precision I'm excluding artificial meteoroids and satellite debris (which is discussed in another question) of all kinds. I'm also considering collisions large enough to produce a noticeable impact or scar (not truly microscopic dust that can only be detected from wear of the surfaces). Say something carrying at least 1J of kinetic energy.

A History of Micrometeoroid and Orbital Debris Impacts On The Space Shuttle lists the "top 20" strikes on space shuttle windows and radiators from 1992 to 2000; most of them are from debris but 4 appear to be from meteoroids. The biggest meteoroid hit appears to be a 5mm hole in a radiator from an 0.7mm meteoroid.

    Hypervelocity impacts on the space shuttle Orbiters were analyzed over the years to determine their origin.




    After the post-flight inspection is completed, JSC
    personnel analyze samples extracted from the impact
    sites using a scanning electron microscope (SEM) equipped
    with energy dispersive X-ray spectrometers (EDXA). Such techniques
    allow engineers to determine whether the impactor was a naturally
    occurring meteoroid or man-made orbital debris.




    The paper ANALYSIS OF THE NASA SHUTTLE HYPERVELOCITY IMPACT DATABASE breaks down the source of the impacts for various regions of the Orbiter.



    The majority of the hits are from debris, but some are attributed to meteoroids. Here's an example, a chart showing the results from the Reinforced Carbon-Carbon areas of the Orbiters (mostly the wing leading edges and nosecap).

                      ASUS Zenbook UX433/UX333 — Configure Touchpad-embedded numpad on Linux

                      Image
                      0 1 I have an ASUS Zenbook UX433,on which ASUS decided to innovate by embedding a Numpad inside the touchpad (see picture 1). Toggling between classic touchpad mode and numpad (also turns the touchpad LEDs on) can be done through the golden button in the top-right corner of the touchpad. However, on my Manjaro arch Linux config, this behavior does not work by default and I can only use the touchpad, no numpad. Has anyone been able to configure the numpad to work on Linux, or have any idea how this could be achieved? EDIT1: I have had a look at the official Windows drivers for the UX433FA TouchPad, but was not able to make anything of it. I tried installing them on Linux using tools like NDISWrapper, but they do not detect the TouchPad/Numpad hardware, and my understanding of drivers is too limited.
