-===== Ribbon/flex cable terminology ===== +
-[[https://www.youtube.com/watch?v=TH4EtRm-Xvs&lc=UgwLrl8ttuvnvD0yW7l4AaABAg]] +

-FYI, that is called a “flat flex cable” (not “ribbon cable”, because that term refers to the thicker, lots-of-round-wires-stuck-together cables like the gray one for the hard drive), or FFC for short. Orange ones like this are made of Kapton (polyimide), not Mylar (metalized biaxially-oriented PET, like in Mylar birthday balloons). The reason people sometimes confuse them is that the metalized Kapton films used on the lunar module and such were often mistakenly referred to as Mylar, even though they weren’t! People often thought one side of those was gold-plated, but the gold color actually came from the Kapton. +

-As for the tear: if you can solder decently, you can use a fiberglass brush to carefully expose the broken metal conductor and then solder a bodge wire to fix it. Alternatively, if the ends of the FFC are standard, which they probably are, you might be able to buy an off-the-shelf replacement and then make a few 45 degree folds in it to make it lay properly. This isn’t a weird hack, it’s actually a common way FFCs are routed in commercial products instead of costly custom FFCs. +

-===== Scrolling adjustment ===== +
-==== Firefox ==== +
-In ''about.config'', change ''apz.gtk.pangesture.delta_mode'' to ''1'' and adjust ''page_delta_mode_multiplier'' or ''2'' and adjust ''pixel_delta_mode_multiplier''. Using ''2'' and ''55'' seems good. +
-==== Libinput ==== +
-In ''/etc/Xorg/xorg.conf.d/30-touchpad.conf''...: +
-  Section "InputClass" +
-          Identifier "DELL09A0:00 0488:121F Touchpad" +
-          Driver "libinput" +
