[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.

[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

[BSD] all the BSDs seem to carry a 90s vibe...

 Just read that blog, 1000% with the reasons, issues not only with OpenBSD, FreeBSD as well - lets put aside NetBSD as IMHO is mainly retro-OS- suffer from various issues. Secure and stable OS . yes - but FFS please provide some good support for VM, USB, ACPI, video acceleration.

[debian] Notes on using OpenBSD under virt-manager

* CDROM must be SATA

* Remove the "tablet device" from the preferences, as I've encountered some issues with it.
I'm using CWM on both the host and guest, and I've noticed some strange behaviour with Virt-Manager. Specifically, when I use Alt + mouse to move a window, it affects the virtual window on the host instead of the guest.

[debian] nmtui error: settings plugin does not support modifying connections

Another 'cryptic' error from this goddamned OS, oh well... solution (as I read on various posts on web) :

edit  /etc/network/interfaces and remove any reference to the eg wired, reboot .

BTW keep the setting managed=true on /etc/NetworkManager/NetworkManager.conf in the case you use NetworkManager (nmcli etc )
