[ubuntu] darn GTK4 apps don't follow dark theme

Fresh install of Ubuntu Unity , smooth transition, just few fixes, alas some darn GTK4 apps - eg the half-baked file-roller - don't give an F about the dark theme I have (yaru-dark), they also don't obey anymore the  ' dconf write /org/gnome/desktop/interface/color-scheme "'prefer-dark'" ' that works nicely with GTK3 apps.. (FFS really) , took a while to find the solution, put this 

export GTK_THEME=Yaru:dark

into your .profile

[fix] HP stream 11 repair

Dead HP Stream 11 - there was no power LED (a.k.a. charging LED).

Strangely, it powered up briefly -just for a few minutes- so I assumed something was wrong with the battery charging circuit. A quick test (alas, no schematic of this rubbish - not mine, by the way... I wouldn't touch HP with a barge pole, with the exception of the 12c :-) ) revealed the culprit: continuity between the gate and source of a MOSFET!


bad MOSFET. Note the capacitor (top right); it's a bit burned but works (checked, lol)


IC ordered from AliExpress (EMB02N03HR) and all is well! Some more life for that rubbish... weirdly, it died just a few months after the warranty period expired. HP "quality", I assume.
