Bug#996417: xset: handle absence of DPMS support in the X server more gracefully
Package: x11-xserver-utils
Version: 7.7+8
Severity: normal
Tags: upstream
X-Debbugs-Cc: tg@mirbsd.de
My ~/.xsessionrc has:
xset dpms 0 0 0
With a regular X11 session, this works, but in an xrdp+xorgxrdp session,
it fails because the server lacks DPMS support. But then, once having
failed on the dpms keywords, it interprets the 0 as another argument,
instead of first parsing the "dpms [standby [suspend [off]]]" then exiting
as there are no further arguments:
server does not have extension for dpms option
xset: unknown option 0
usage: xset [-display host:dpy] option ...
To turn bell off:
-b b off b 0
[…]
This is, of course, both suboptimal and avoidable by moving the parsing
of the dpms-related options to before the check for its presence.
