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

randr 1.3 introduces the GetScreenResourcesCurrent request, which
doesn't call back into the driver.  This fixes at least the xserver part
of this bug.
