Is it at all possibe?

Hey,

I thought about taking the plunge, and trying out KDE4.

Its kinda annoying switching back and forth KDE4 and KDE3.5 (I have to use KDE3.5 for
productive reasons), and I'd like to know if its at all possible to have KDE4 on one of my
four desktops, and KDE3.5 on another, allowing me to "switch" them simply by moving
to the other desktop.

I guess my question is simply if its possible to run 2 DE simoultanously under X.

Thanks
Fiod

My rather limited knowledge says "no".  You can't run two window managers simultaneously, and I think that you could run into trouble from duplicating some of the basic KDE services.

You can run xmonad or openbox intergrated to any desktop environment though

I don't use KDE (I just tried the kde4 release) but I had read you can use kde3 applications in kde4 (not sure it's ok on opposite way).
But if you use KDE for productive reasons, I think it's better to stick with the kde3 version for now. I don't understand why you switch from one to the other ?

Edit : wrong answer.

Re: Is it at all possibe?

Actually, you can.

Basically, you have to start two seperate X sessions.  I did this with KDE 3.5 and KDE 4.1 SVN before.

Graphically, start one (say KDE 3.5), and then select switch user and log in as the same user but this time select KDE 4.1 in KDM.

I don't remember how to do this in the terminal...

Anyway, once that's done, you can do Ctrl+Alt  F7 or F8 to switch between them...

There's no way to do that with virtual desktops as far as I know...  However, I have run kde3.5 on top of kde 4... it was... interesting...

But if you use KDE for productive reasons, I think it's better to stick with the kde3 version for now. I don't understand why you switch from one to the other ?

Well if you're like me, you might love experimenting with things...  I usually have a few desktop environments installed, and an assortment of applications I don't ever really need to use but they're fun to experiment with...

I didn't know that, I edited my last post to remove the "no you can't" and did some research and found this article explaining how to run two DE at the same time.

Nice article...  I never knew about making a program appear in another session... 

I wonder if that can be done over a network...

X can listen to TCP connections and you export the DISPLAY to an IP/hostname, you also want to read man xhost. Then there is SSH X11 forwarding, which does mostly everything for you... and so on (there are more ways to do it).

Since we're talking about these things you could also be interested in xpra, it can be described as "screen for X", and it can also run applications remotely...

Re: Is it at all possibe?

You can't do this currently with Arch because there is a conflict between the kde3mod packages and kde4 packages.
SuSe is supposed to have had to make massive changes in the packages to be able to accomplish this feat and our devs for kde4 didn't want to take the time.

At least that's my understanding

Re: Is it at all possibe?

If you wanted to with KDE4, you could download the ABS packages and change the PKGBUILDS so that they install into /opt/kde4 instead of /opt/kde, I plan to do this at some point so that I can test KDE4, it would also mean you could run KDE4 and KDE3 applications side by side. Of course it would take a little bit of testing to get right.

Re: Is it at all possibe?

Oh ok then. I decided to bite the bullet and upgraded to KDE4.

So far so good. Compiz still runs smoothly and aside a few sporadic crashes with Konqueror, the system seems to run as smoothly as it did with KDE3.5.

Though it's still early days, So far so good
