Do you start just _one_ X server and notion handles the two screens
without mod_xrandr nor mod_xinerama loaded as two seperate workspaces?
That's something new to me. 

AFAIK, usage mod_xrandr is encouraged for static or dynamic multihead
setups. However you need a graphics card driver which has randr support.
I had no luck creating two seperate workspaces on two monitors with
proprietary nvidia driver, since it doesn't fully support randr.  I also
had no luck to make notion handle each monitor as a workspace with prop.
nvidia driver's twinview and mod_xinerama activated.

mod_xrandr works for me with nouveau driver on an nvidia machine and on
my mobile intel graphic chip (with dragging xclients from screen to
screen).  However, dragging with mouse will work only from tiled
workspace to any, but not the other way, from a floating workspace to
another (IIRC, there's an issue reported on notion issue tracker. But
you still can use tag/attach way to move frames between any workspaces.

You can get mod_xrandr here:

Hope it helps.

[Notion-general] mod_xinerama

[Michael K. <mic...@rw...>]

Hi,
I want to use notion in my multihead-setup but it does not what it is
supposed to do. If I deactive xinerama it behaves as expected with one
workspace for each screen. But I want to move windows from one screen to
another so I installed mod_xinerama (and activated xinerama of course),
but in fact it does nothing. It behaves just as is was not installed.
(or at least I cannot notice any difference), but it is for sure since I
get an error if I deativate it in the x-server. There is a area i cannot
access in the left monitor (since it's 26 pixels smaller) and also I
like the "fixed" as if the 2 monitors where 2 X-Screens.
Any clues/fixes, or have i missunderstood the usage of mod_xinerama?

Re: [Notion-general] There is no sound

[Thomas A. <t.d...@gm...>]

Seems like the problem of `muted`. But I can not be 100% sure because
previously the sound is not muted.

The way I get it worked again is

First check if it works in gdm3 by reinstalling gdm3 and choose gdm3
as the default display manager.

Second, after switching back to slim, launching alsamixer to check Master, PCM.

Third, in alsamixer screen press m to make sure the bar in Master and
PCM is not shown with MM, which indicates it is muted.

Thanks again for the help.

I appreciate it.

Re: [Notion-general] There is no sound

[Thomas A. <t.d...@gm...>]

Environment I am using is Debian with kernel 2.6.34.1. Notion version
is the latest one from git ( time stamp on Sat Mar 12 00:26:18 2011
+0100). The display manager is slim, version 1.3.1. Before posting
this sound problem, I'd almost removed everything about gnome library,
such as gnome-desktop-environment, gnome-session, and gdm3.

Now I try installing pulseaudio and executing command

    ps -ef | grep pulseaudio

returns process

    /usr/bin/pulseaudio --start --log-target=syslog

but I still have no sound. Checking alsamixer, it shows the Master and
PCM are at max (100<>100).

Playing video with mplayer in terminal (e.g. tty 2), sound is not
working. Also, after reinstalling gnome-session and rebooting the
system, sound is still not available.

I think my problem is that I do not know where to check e.g. logs,
etc; how to setup sound/ mixer in notion.

So generally what e.g. sound mixer is launched when you use notion?
And where (log files) to check if it is running or not?

Thanks for help.

[Etan R. <de...@un...>]

GNOME is a desktop environment, notion is a window manager.

GNOME runs all sorts of things in the background for you that notion does
not.

In this case GNOME was most likely running some sort of sound mixer/etc.
application which was controlling the volume of your system speakers
automatically.

You will need to find a similar application (or even just the GNOME one)
and see if you can get your speakers activated correctly (my guess is that
they are either muted or have their volume levels set to zero).

[Notion-general] There is no sound

[Thomas A. <t.d...@gm...>]

Previously when my desktop runs with gnome (dgm3), I can hear sound
without a problem. However, after switching to use notion, I notice
that I no longer able to hear any sound from media. For instance, go
to youtube, there is no sound. The same when I play video with
mplayer.

I am sure the hardware should work ok because when switching to
windows 7, I can hear sound played from media e.g youtube, etc. Also,
alsamixer shows that volume is shown up including Master, Headphone,
Speaker, PCM, Front, Front Mic, Front Mic Boos, Line, and Mic.

What files do I need to modify?

Thanks.

Re: [Notion-general] How to change default term and adding environment variable

[Thomas A. <t.d...@gm...>]

Thanks! I copy cfg_notion.lua from source ($NOTION_SRC/etc/).
Uncommenting and changing xterm to the one I previous use, and it
works.

At the top of cfg_notion.lua (if you don't have one in ~/.notion you
should copy it from the system location to there) there is a commented out
line:

--XTERM="xterm"

uncomment that (remove the --) and set it to whatever terminal you want it
to run.

That being said I'm not sure sure setting environment variables or running
more than one command is going to work well that way. What are you trying
to accomplish by doing that?

[Notion-general] How to change default term and adding environment variable

[Thomas A. <t.d...@gm...>]

I build the source and install notion on my laptop. But I have a
question. How can I change the default term for notion?

After searching on the internet, I come across a page at
https://wiki.archlinux.org/index.php/Ion3, which says editing
cfg_bindings.lua. But I notice that within .notion, there is not such
file; and the cfg_statusd.lua does not allow user editing its content.
How can I change the default terminal and adding environment variable
e.g. `export ...` or `program&`?

Thanks.
