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

It looks like an output can only be mentioned once, so xrandr --output VGA-0 --auto --output LVDS --auto --output VGA-0 --left-of LVDS won't work. So, a little more command line processing is necessary. Right, I fixed this in the upstream xrandr git. It will work in the next release. I also clarified the manpage about the ability to manage multiple outputs at the same time with a single command line. As said by Michel on IRC, the original problem is in the server. It should cache output infos and let xrandr retrieve them without querying the hardware again. It would be much better than trying to cache things in xrandr or so. I am reassigning the bug report accordingly. Brice -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

It looks like an output can only be mentioned once, so
xrandr --output VGA-0 --auto --output LVDS --auto --output VGA-0 --left-of LVDS
won't work. So, a little more command line processing is necessary.
For the record, here my current script:
$ cat .my/bin/xrandrauto
#!/bin/bash
if ! TMPFILE=$(tempfile --prefix xrandr); then
echo 2 ERR: cannot create tempfile
exit 1
fi
xrandr $TMPFILE
CONOUTPUTLIST=
OUTPUTLIST=
OPTIONS=
for output in $( $TMPFILE sed -n '/[^[:space:]]\+
connected/{s/\([^[:space:]]\+\).*/\1/;p;}'); do
CONOUTPUTLIST=$CONOUTPUTLIST $output
OUTPUTLIST=$OUTPUTLIST $output
OPTIONS=$OPTIONS --output $output --auto
done
for output in $(xrandr | sed -n '/[^[:space:]]\+
disconnected/{s/\([^[:space:]]\+\).*/\1/;p;}'); do
OUTPUTLIST=$OUTPUTLIST $output
OPTIONS=$OPTIONS --output $output --auto
done
if [ $CONOUTPUTLIST = VGA-0 LVDS ]; then
OPTIONS=$(echo $OPTIONS | sed s/\(--output VGA-0\)/\1 --left-of LVDS/)
elif [ $OUTPUTLIST = LVDS ]; then
OPTIONS=$(echo $OPTIONS | sed s/\(--output LVDS\)/\1 --pos 0x0/)
fi
xrandr $OPTIONS
rm -f $TMPFILE

How would that call look like? xrandr --output VGA-0 --auto --left-of LVDS --output LVDS --auto? Yes you can probably do something like that. At least, I know that xrandr --output LVDS --off --output TMDS-1 --rotate left --auto does what I want on Intel (disable LVDS and set TMDS to preferred mode rotated to left) Also, --auto seems to work with and without a --output specified earlier. So you should be able to do xrandr --auto --output VGA-0 --left-of LVDS If so, this possibility should be mentioned in the manual page. Right, it is not really explicitly explained in the manpage, I'll try to improve it. Brice -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

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

Right, it would be nice, especially when calling xrandr blanks the screen
during a second or so.
Of course, patches would be wellcome :)

You should be able to call xrandr only twice here. One to get the output
and save it (and apply sed multiple times to compute OUTPUTLIST), and
one to pass --auto for all outputs and set their position.
