Bug#544518: A way for --prop to not take half a second
Package: x11-xserver-utils
Version: 7.4+2
Severity: wishlist
File: /usr/bin/xrandr
Hi,
wouter@celtic:~$ time xrandr --prop
[...xrandr output snipped...]
real 0m0.444s
user 0m0.004s
sys 0m0.008s
I currently have a shell script that does the following:
BL=$(xrandr --prop|awk '/BACKLIGHT:/{print $2}')
with the intention of then being able to use that to compute stuff and
set the new value, and hook that to the XF86MonBrightnessDown and ...Up
keys as a hotkey.
However, due to the fact that xrandr spends almost half a second waiting
on the X server for information that I don't need, and combined with the
fact that I don't see any way for me to change the set of data that
xrandr requests from the X server, this script is nearly unusable.
There could be alternate solutions to this wishlist item; e.g., it would
help if I would be able to tell xrandr that the X server has to increase
the value of a property relative to its current value with a value
relative to its valid range, or some such (say, a command similar to
'increase the value of the BACKLIGHT property on the LVDS output by 10%
of the total range).
