Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.
Sometimes you move the folder to which lots of symlinks were pointing, or something to that effect, and you want to simply "edit" these symlinks rather than recreating them pointing the correct new location. That's how it can be done with one line:
Code:
find /place-where-the-null-symlinks are/ -type l | while read nullsymlink ;
do wrongpath=$(readlink "$nullsymlink") ;
right=$(echo "$wrongpath" | sed s'|/whatever/is/the/old-wrong/path|/correct-new/path|')
There had been a weird problem with sound on Arch. Whenever there was a flash item being displayed (or perhaps flash using sound, I suppose), there would be no sound elsewhere. And if there were sound elsewhere, whenever you play something on flash, it would conversely be mute.

By "work" I mean having "hovering" and "keepshape" mode, not just a worthless slow "pen-mouse". My thinking is that it wasn't working due to concurrent configuration files. There isn't only xorg.conf, but on /etc/X11 there is a xorg.conf.d folder, and there there was a ##-wacom.conf or something, with different settings than the ones I had set manually on xorg.conf.
HAL is deprecated, or something like that, and I don't have any .fdi file for...
Apparently I got it working. It did do a preview scan, with color, on xsane, as a normal user, so it's almost 100% sure it is OK. The only thing I think I may have had to do different from Debian was to set a udev rule and change user permissions/ownership on /var/lock/sane. Some people said that just udev or permissions alone would do it, but I had the impression I needed both, but that's possibly wrong. I don't see anything wrong in having both, so I'll just leave it as it is, as it is working....
