[fedora] darn abrtd reports Rhythmbox as 'crashed' on close/exit

I bet this is an ancient bug, as there have been posts on the internet about it for ages!

Solution (at least works for me now on F42/Gnome)

edit /etc/abrt/abrt-action-save-package-data.conf and append two lines:

Blacklist = rhythmbox 

BlackListedPaths = /usr/bin/rhythmbox*

This will blacklist rhythmbox from abrtd reporting.

[*] 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

Update

Same crap on Fedora (F42) Gnome ! This time fixed by adding : 

export GTK_THEME=HighContrastInverse 

on my aliases file under the  $HOME/.bashrc.d directory
HighContrastInverse a bit more 'compatible' with the HighContrast on Accessibility -if you like that.
btw you can use something else eg GTK_THEME=Adwaita:dark . still some apps may have broken interfaces because of this, eg style and accent colour are not working anymore (effing mess there ... )

[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.

[fedora] (some) videos on YT laggy under chromium

I've recently had the 'pleasant' experience of watching some videos on Faildora's Fedora's Chromium; they were laggy as hell, especially when viewed in SD resolution. However, you could play them using Google Chrome or Firefox. There wasn't much to find on their forum/Reddit.

After some tries, here is the darn solution: this is an issue because of a screwed-up "free" ffmpeg package (ffmpeg-free), replacing the 'free' one with the version from RMPFusion did the trick!

so:

a/ install RPMFusion

• sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

b/ replace the ffmpeg

• sudo dnf in ffmpeg --allowerasing
