[Fluxbox-users] Dual head maximize and full screen spans across

[Jj]

I have had a dual screen set up in fluxbox for around 10 years, but I
always used two independent X sessions per monitor and I never had a
problem and never really missed the need to drag windows across screens.

Last night I just got a third monitor for the first time so I wanted to
configure it as 2 X sessions, one for the new big one and the other two
screens to share their own X session.
This means that I should now be able to drag stuff between them and
switching workspaces would link those two together.

My problem now is maximizing and full screen. It happens across both
monitors that share their own X session, Opening new windows many times
ends up with them being split in the middle and makes it annoying since now
I need to size stuff manually to adjust to the dimensions I want to match
one of the screens.

I have NOT enabled Xinerama enabled since that's a ServerLayout directive
and doing so would affect ALL screens linking them all three together.

I have used fluxbox for a decade but never on this configuration. I was
unable to find info online about how to handle this. Am I missing something?


Here is my Xorg.conf

# nvidia-settings: X configuration file generated by nvidia-settings

yep. but you have to xinerama/twinview the 2 monitors together to one "screen".

i would add this:

Option "TwinView" "1"
Option "TwinViewOrientation" "DFP-1 LeftOf DFP-0"
Option "MetaModes" "DFP-0: nvidia-auto-select,DFP-1:
nvidia-auto-select; DFP-0: nvidia-auto-select,DFP-1:NULL;
DFP-0:NULL,DFP-1:nvidia-auto-select;"

(or something that reflects your attached monitors). the idea is to
provide here "one" device that has multiple monitors connected to it.
but treat it as one device.

Post by Jj
Section "Screen"
Identifier "Screen0"
Device "Device0"

and this would pick the setting from above up. should work.

for fluxbox itself: you need the xinerama-option to be compiled in.

hope it helps,
cheers,

[Jj]

This is great, thanks a lot. But I think there's a line you missed right
under the "Screen" section?
I added the options to the Device section, but behavior is the same.

which one?

is your fluxbox compiled against xinerama and xrandr?

[Jj]

You mentioned this on your fisrt reply:

"""

which is how the current Screen0 is configured, so I thought you meant that
there was something to add to that screen's section other than the existing
conf.


This is my fluxbox info, it has Xinerama and RandR enabled. Do I need a
newer version?

nah, i was just refering to the place of your config which should then

XINERAMA

looks ok.

so, "xrandr -q" lists the correct amount of monitors for that screen
with the multiple monitors?

[Jj]

Yes it does:

[~] xrandr -q

Screen 0: minimum 8 x 8, current 3120 x 1050, maximum 16384 x 16384
VGA-0 connected primary 1680x1050+0+0 (normal left inverted right x axis y
axis) 474mm x 296mm

looks good. how about "xdpyinfo"?

if fluxbox maximizes windows across both monitors it has not detected
xinerama correctly. it should, since twinview is a flavor of xinerama.
you might also want to try to remove that xinerama-line from your
serverlayout-section, it should still use "real" screens.

cheers,

[Jj]

(Re sending with smaller attachment)

Removed the Xinerama 0 option from Xserver and restarted. Symptom remains.
Is there maybe a way to output what fluxbox is reading and recognizing as
it starts up?
The ~/.fluxbox/log file doesn't have much information right now.

If it is help at all, I'm running Ubuntu 14.10 and booting via LightDM, it
launches the a startfluxbox script which is clutter and `exec fluxbox`.

I made sure that the binary running under /proc/`pid`/ is the fluxbox
command I was looking at, its info shows xinerama enabled.

well, your xdpyinfo shows that your server is not running with
xinerama (the extension is not loaded). try to enable it somehow ..
your problems should go away :)
