Bug#455225: /usr/bin/xrandr: please consider possibility to disable hardware detection

[Marc Haber <mh+debian-bugs@zugschlus.de>]

Package: x11-xserver-utils
Version: 7.3+2
Severity: wishlist
File: /usr/bin/xrandr

Hi,

when invoked, xrandr does detection of hardware capabilities and
connected monitors. This takes a few seconds to complete.

I have a script, xrandrauto, which invokes xrandr multiple times to
create the screen layout that I want to have. However, this script
takes like 30 seconds since xrandr repeats the detection process over
and over.

Please consider adding an option to disable the hardware detection and
to use whatever was detected the last time.

Greetings
Marc

  xrandr --output $output --auto
  OUTPUTLIST="$OUTPUTLIST $output"
done
for output in $(xrandr | sed -n '/[^[:space:]]\+ disconnected/{s/\([^[:space:]]\+\).*/\1/;p;}'); do
  xrandr --output $output --auto
done

if [ "$OUTPUTLIST" = " VGA-0 LVDS" ]; then
  xrandr --output VGA-0 --left-of LVDS
elif [ "$OUTPUTLIST" = " LVDS" ]; then
  xrandr --output LVDS --pos 0x0
