Default Display gamma.

Hi.
I would like to use OpenBSD on a daily basis, almost all soft I need presents in repos. But there is a stoppable moment: I did not find xgamma package (or something like) for increase brightness of my ancient CRT monitor (yes, such life, for now).
https://cloudflare.cdn.openbsd.org/p...ackages/amd64/ Would you please advise what to do? Thank you.

Hi,

You can search for packages on this site http://openports.se/

Here are the answers I get:
- x11/gnome/color-manager
- x11/kde4/kgamma
- x11/gammapage (the package name is GAMMApage)

I'd try the latter first. The two other ones should only be used if you already have Gnome or KDE installed.

Not OpenBSD user, but since xgamma is a native Xorg app, it should be included in Xenocara with xbase${version}.tgz binary set and already present on your system if you followed a guided installation from a live CD. In fact, see OpenBSD's xgamma(1) man page. Remember you have also xbacklight(1). I don't think xbrightness has been ported to OpenBSD too instead.

Anyway, usually on BSDs, the best way of adjusting brightness is through sysctl or wsconsctl tunable values handled by a dedicated ACPI display driver, which is acpi_video(4) in FreeBSD, acpiout(4) in NetBSD and seems to be acpivout(4) on OpenBSD.

Adjusting brightness at hardware level even outside Xenocara should be as easy as:
Code:
wsconsctl display.brightness=$BRIGHTNESS
To set the wscons brightness value permanently at boot, this should work, assuming wscons.conf here has a similar vars to other BSDs:
Code:
echo "setvar  wsdisplay   display.brightness         $BRIGHTESS"  >> /etc/wscons.conf
Hope this helps
