Idea #3442: "Click-n-play" Multiseat support

Description
A feature that's possible but not intuitive in Ubuntu today is the setting up of one PC as "multiple workstations" - i.e. connecting two keyboards, two mice and two monitors to one PC and having two users log in and work independently.

I would love to see this feature made simpler to set up, as it would be great for a lot of home users (e.g. buying a one powerful computer instead of 2 or 3 computers for the kids), as well as in schools, internet cafes etc.

I have all the hardware sitting right here not being used, waiting for userful to work on Hardy. Even when it does, what Sceens and Graphics does not understand, it will destroy.

Voted up as far as I could (1).

Yes! I wanted sometimes so set up a multi seat Desktop.

The idea was that one Monitor (on one graphics card) is used for multimedia (watching tv and listening mp3) and its X is using sepcial devices for input like a remote control. And another Monitor (on an other graphics card) can be used for working. So that I could work mith my normal Mouce and Keyborad in a clean X session while an other clean X session is just listening to the remote control (in other words: my girlfried could listen mp3 without bothering me at work on the same station). But I was never able to get this run, since a new X only starts with its own keyboard defined and I was not able to get the kernel rebuild for supporting 2 keboards.

+1

Canonical needs to purchase or obsolete userful and integrate said function right into Screens and Graphics.

I'm running dual seat right now. It's not as transparent as I'd like, it involves proprietary software, it's not well integrated, not set up exactly how I need it to be, and so on and so forth.

The audio's good, cause I have PA running in system mode with two virtual mono sinks. Each user gets one speaker ^_^
...but the input device handling doesn't use product hex options, both seats are one one card, when i wanted to use two, etc.

OOTB multi-seat can add a /ton/ of value to Ubuntu in the enterprise and would be a clear demonstration of its superiority over competing platforms.

I've been trying to achieve this with my Ubuntu box for the past couple of weeks, in the end I just gave up. I have a couple of fairly powerful machines which would all make use of a multi-seat setup. Not only does it mean that some of the spare CPU power is put to some good use (I mean, who uses 4 cores of a CPU for basic web browsing, I haven't even managed to max out my quad core system with working on videos etc), it's also better for the environment (I dare say it's still going to use less energy adding another monitor, keyboard and mouse).

Practically every time I tried to setup a multi-seat configuration it just failed, either with it going into failsafe X mode or just not booting up X at all.

I registered to be able to vote for this idea. I keep it extremly important, and needed. Actually I expected some overwhelming feedback from the community...

snadrus, thanks for intentionally duplicating this idea and clarifying it. I've voted again; this really has a massive potential for Ubuntu (think schools, hospitals, internet cafes, even home users!)

Way better explained than the one I put( #7861 ),good job bro!

Are we looking for a multi-seat manager then.
I think this should be made default but optional.

andersja wrote on the 7 May 08 at 15:09
This is not an exotic request - many users are trying to achieve this (currently with lkittle success):

Worth keeping an eye on (but according to ubuntuforum hints by Corey Burger, open source Userful has been hinted at since 2005 = slow moving):

The school board I work for (5000+) students has been looking to do this for a while (and on Ubuntu as well).

They found some commercial software to support this, but it's for Ubuntu 5.04 only (yikes!)

This needs some serious thought and resources applied.

Trying to achieve this now and its impossibly difficult, apparently Fedora has better support for it. I don't see why Ubuntu can't fix this issue, it'd be a major advantage over the big boys.

For research purposes, here is a program with similar functionality for Windows:

I have seen this in action.

It is also useful to take a look at http://www.linuxtoys.org/multiubuntu/multiubuntu.html

I quite Userful in June of 2007. It is unlikely that they are going to open source their multi-seat stuff. When I left, they had also not ported it to xrandr.

Ok, I can type first thing in the morning. I should have said "quit" not "quite".

Multi Seat Display Manager is the newest development in this field and it looks very promising! They even provide a livecd based on Ubuntu to try it out:

This is the single most important addition.

Part of the issue is that the "haves" do not have a need for it, they just buy more computers. The "have nots" have zero or very little computer access so they cannot learn and let alone develop this capability.

So much toxic e-waste and general waste by the affluent "haves".

Eventually it will become necessary when the tables are turned - then it will become available in the blink of an eye.

Does anyone know whether MDM / Multi Seat Display Manager / Multiseat Display Manager (http://www.phoronix.com/scan.php?page=news_item&px=NjczMg ) is included in Intrepid? This is a HUGE step forward! I'm very interested!!

andersja wrote on the 30 Sep 08 at 13:55
Wow ! .deb Packages for Hardy available here! http://wiki.c3sl.ufpr.br/multiseat/index.php/Installing

bastafidli wrote on the 12 Oct 08 at 06:00
I completely agree, this is huge. MDM is exactly what was needed. It works perfectly on the live CD out of the box. The sooner it gets into official distro the better since whichever distro gets it integrated first will be probably the distro of choice for all the places where multiseat is must.

I REALLY would like to see this feature added to Ubuntu. I echo all the requests for MDM. According to Phronix the next release of Fedora (Fedora 11) will have MDM by default.

I hope Jaunty won't be left behind and will get this as well.

This is a really good idea. Although I do not really have a use for it, I can see the potential that this offers, especially where money is limited etc.
