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.

KDE/QT dialogs in GTK/Gnome, or, "that's a good question".

Well now Qt uses GTK dialogs in GNOME. Why can’t Gtk “repay the debt” and use KDE dialogs in KDE?

http://blog.qt.io/blog/2008/10/01/na...logs-in-gnome/
I didn't even know that KDE did that/allowed to do that (alongside with GTK2 theming, which again, doesn't work in the other direction).

How nice would it be if it was reciprocal.

I simply don't understand some UI developers philosophies. Like "lets...

Silent pulse audio output detection/indication, with bash + arecord

Posted 10-02-2016 at 03:16 AM by the dsc (linux-related notes)

You can "grep" something at /proc or whatever that tells whether there's some sound theoretically being played, but it will give a false positive when "silent sound" is being played.

A clumsy hack along these lines can detect "silent audio" as silence:

Code:
while true ; do 
arecord -d 1 -D pulse > /dev/shm/test-audio 2>&1 
cut -c 300- /dev/shm/test-audio | grep -a [[:alpha:]] > /dev/null && echo sound

Bash xdotool+wmctrl "daemon" that maximizes "almost maximized" windows

Tags openbox, wmctrl

I find annoying that, for whatever reason, it seems that some windows get "almost maximized" (I have the impression that some browsers do that by "design", even though I'm not sure), and then I end up clicking in a desktop pixel instead of the scroll bar or something. In my case that action is assigned to show the desktop/minimize all windows.

So here's what I just came up with so far, for a 1280x1024 resolution:

Code:
while true ; do sleep 3

Script to watch potentially misbehaving processes and kill them if needed

Posted 09-30-2016 at 10:09 AM by the dsc (linux-related notes)

Tags cpu, hang, kill

A second adaptation of an adaptation of this script:
http://searchenterpriselinux.techtar...sses-with-Bash

The original adaptation was supposed to put any misbehaving process under cpulimit leashes, I'm not sure it's working properly. I've made a more radical implementation intended for programs that are more likely to misbehave and probably hang with high cpu, when killing them after a while seems to be a good idea.

Autostart script method to fix the GTK3 scroll-warp feature-bug

Posted 09-27-2016 at 07:41 PM by the dsc (linux-related notes)
Updated 09-27-2016 at 07:44 PM by the dsc

I'm not aware of there being something like a "gtk-3.0-settings.d" to preserve settings.ini options between theme changes (including involuntary ones), so that's a work-around method, adding that to the session auto-start script:

Code:
! grep warps-slider $HOME/.config/gtk-3.0/settings.ini && echo "gtk-primary-button-warps-slider = false" >> $HOME/.config/gtk-3.0/settings.ini
But that of course only works after a new login (not mentioning...
