I am not sure what's happening to you folks. I have the 'xrandr'
package in my home profile [1] and it runs fine.

Well, Guix is a bit different. What does it mean for 'xrandr' to be
installed? It's obviously in each of your /gnu/stores because XFCE
probably uses it under the hood, but it's not available in your

Whatever aggregates the manual pages may be more zealous than the
infrastructure that builds executable profiles. I am too new to Guix.

You can find the manual page by running (in Bash):

  $ find `echo $MANPATH | tr : ' '` -name 'xrandr*'

Sorry about the shell scripting. That should really be in Guile.

Then you can run 'ls -al' on the resulting path. For me, it looks like

  $ ls -al ~/.guix-profile/share/man/man1/xrandr.1.gz

which produces

  lrwxrwxrwx 1 root root 83 Dec 31  1969
/home/lechner/.guix-profile/share/man/man1/xrandr.1.gz ->

You can probably find the xrandr executable nearby. Locally, I can run

  $ /gnu/store/hhdalqvr3dgsapmh8n6wkha6gm6wklrx-xrandr-1.5.1/bin/xrandr

which produces the customary (and lengthy) xrandr output.

Sorry, I didn't mean to take a position of any kind. You are right.
Xrandr is actually pretty decent.

I have used X since it was called Xfree86 and when backing store had
to be enabled manually due to the AT&T patent. [2] It's not a great
code base by any means. I thought that was universally acknowledged
but cannot find a reference right now. My comment was meant to
encourage the use of Wayland whenever possible.

I didn't mean to reflect poorly on XFCE, either. Personally, I am
still on X just like you and Gottfried, because EXWM supports only
that. My three monitors flicker every time xrandr sets them up, and
every so often some do not turn on. I have relatively old equipment,

I am glad it's working for you! Will you please help Gottfried?


Kind regards
