I have been playing a bit with xgamma and I think it can be useful as a
graphical
notification for important alerts like low battery or so.
The usage is quite simple. and we can 'flash' the screen in red for a
fraction of a second with:
What happens if you're not looking at the screen?
I modified `slock' some time ago to display a fullscreen red window
that closes on any button press. I use it to notify about low battery.
The code is attached.
Example usage:
$ ./redscr
a red windows appears
$ ./redscr 336699
a baby blue window appears

That reminds me, I used to use xrefresh for something similar. xrefresh -solid red If you have a fancypants graphics card it might not last long enough to notice.

Re: [dwm] xgamma notify
urxvt seems to ignore xgamma. So although it's a great idea, it isn't much help if you only have some terminals open.

Re: [dwm] xgamma notify
I use xterm and it is affected by xgamma, the grey letters become darker for a while. Sounds strange that urxvt isnt :? Alan Busby wrote: urxvt seems to ignore xgamma.

Re: [dwm] xgamma notify
xgamma just changes the gamma, which may not be noticeable on things that are predominantly black and white. Here are a few suggestions that will set actual brightness: xbacklight =[some-value] xvattr -a XV_BRIGHTNESS -v [some-value] These may not work on all systems, but will probably work on most laptops. See man pages for further information on these commands.

It has the nice advantage that if I'm not looking at the screen that instant, it'll be around when I come back to it. And also the screen doesn't explode.
