Ubuntu :: Will It Be Possible To Maintain Multiple Sessions

Oct 4, 2010

Will it be possible to maintain multiple sessions from Ubuntu?Actually we are working on one open source application and we have setup this application on one of our Ubuntu machine and this would act as a server for other developer's windows machine. Is any utility available(preferable open source) using which we will be able to access the Ubuntu server from all 4-5 developer's Windows machines?

Our requirement will be to access the whole system including console and GUI (same like remotely access) by using different sessions so that all 4-5 developers can start work together on the same Ubuntu machine.

Debian :: Multiple Sessions With X Window

Jan 18, 2011

I have two Debian boxes, A and B. I would like that a window (for example vlc, or whatever) displays on both A and B. The process (i.e., the X11 client) runs on A. If I interact with the window from box A, it should affect the window on box B. And, if I interact with the window from box B, it should affect the window on box A.

Software :: Multiple Sessions With Different Resolutions

May 9, 2011

I just bought a tablet, I would like to VNC to my machine with a lower screen resolution to match my tablet. Right now I use x11vnc on Ubuntu 10.10, and I was thinking to start another session using "startx" but I see there are parameters for display depth but not resolution.

Ubuntu Networking :: Vnc4server Starts Multiple Sessions?

Jul 1, 2010

if i stop that session, and come back later, it will have me log on at the login screen, but start a new session, with multiple instances of things..now, with vino, i could just keep the same session running, and when i VNC in, it just resumes it.. This one starts a new one.. i even tried just locking the screen, and it still starts a new one...i know there is an easy fix.. lol.. i just cannot find one.. i REALLY like how it shows me the ubuntu login on my server.. that is slick, so id like to keep that, if possible.

Ubuntu :: Multiple X Sessions - Auto Login 2 Different Users

Oct 11, 2010

I have a small problem regarding multiple X sessions. I want 2 X sessions started automatically on boot with 2 different users auto logged in and 2 different sessions running.

On first X session I would like to have gnome running with user1
On second X session I would like to have xbmc running with user2
So far my computer logs user1 in to a gnome session via gdm on boot. But then I have to launch a tty, log in as user2 and then start xbmc in a new X session.

How to make it work? I would also love to have the second X session active after boot. I am running Ubuntu 10.04.

Debian Multimedia :: Using Startx For Multiple X Sessions

Sep 20, 2015

I have been able to log into a tty[1-6] as root or my user, and then startx -- :1, while logged in as myuser and running X on tty7, , but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?

Related 2nd question: When I did the above startx -- :1, it would start the X session in the same tty (e.g. tty2) where I was logged in when running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work?

Applications :: Writing Commands To Multiple Sessions?

Jul 12, 2010

I am using putty to connect to some servers. Is there a program that let you connect to say three servers and when you write your commands to server1, server2 & 3 also gets the command? So I don't have to log in to all three servers to do the exact same thing.

Debian :: Iceweasel - Secure Sessions On Multiple Profiles

May 18, 2010

I'm having problems establishing secure sessions with my bank's online banking service provider. I've already contacted their local tech and together we were unable to solve the problem. I've tried deleting my cookies, session store, cache, and none of it worked. He's currently forwarding our conversation to the service provider's tech support line, but who knows what will come of it. Or even if they will offer support for an iceweasel user. I'm using Iceweasel 3.6.4~build2-1 out of the experimental repo.

I'm able to login successfully to online banking site to view my list of accounts, however if I try going any further than that, I'm redirected to an error message page that tells me a security error has occurred - the online session has expired. I get this on browser profiles 1, 2, and 3, however I do not get the error message on profile '0' (default) or on newly created profiles. And as mentioned earlier, I've tried deleting all persistent data (cookies, session, cache) on a non-working profile and the problem still exists. Let me know if I can provide any more information.

Debian Multimedia :: Gdm3 / Gnome And Multiple X Sessions

Sep 11, 2015

Running Jessie (with a low-pinned Debian-based repositories added to my sources.list (e.g. Kali, kxstudio) for those packages not currently available on Debian (like the Kali menu of security tools). Running on a HP 15-r189nd (Energy Star) laptop.

First question: How do I get GDM3 to add root as an option during login? I can type the root user name in. I don't need it to show the root user in the user list (would actually prefer to need to type it in), but I do want to be able to start an X session as root, since some of the Kali tools (e.g. nmap) needs root to function fully. If I type in root and try to start, it just takes me back to the GDM3 login.

Second question: When I want to select my Desktop Enviroment/Window Manager in GDM3, the list appears below the little gear so I can only see half of the list (xfce not visible to select). How do I change the GDM3 appearance/settings that will change the position of the DE list?

Third question: How do I get multiple X sessions running simultaneously? What I have been able to do, while logged in as myuser and running X on tty7, is to log into a tty[1-6] as root, and then startx -- :1, but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?

Fourth question: When I did the above startx -- :1 as root, it would start the X session in the same tty (e.g. tty2) where I was logged in as root running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work? Or is there something wrong with my setup?

Question 5: Once I have started an LXDE session as root, how do I get it to show the full application menu that my regular user can see? Can I just copy the config files over? Which ones? Or is there a better way?

Question 6: Gnome used to start fine. Then I ran Gnome on Wayland once, and now regular Gnome (on X?) no longer runs, but give me a "Oops! Something went wrong" error and Alt-F4 just takes me back to GDM3. Classic Gnome and Gnome on Wayland still runs OK. Should I log a bug report?

Server :: Automating Multiple Minicom Sessions Simultaneously

Oct 5, 2010

Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.

Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.

Software :: Multiple Concurrent Remote Desktop Sessions?

Feb 28, 2010

I currently have a RHEL 5.4 software development server. A lot of my developers are using windows desktops and they need to run interactive sessions on the server. I need to support between 4-6 concurrent users on the server. I tried doing this with VNC but I was never able to set that up for more than one user at a time.

General :: Launch Multiple Screen Sessions From A Single Bash Script?

Jul 11, 2011

I've written a script (that doesn't work) that looks something like this:

#!/bin/sh
screen -dmS "somename" somecommand
for i in {0..5}; do
screen -dmS "name$i" anothercommand $i
done

For some reason, if I copy and paste this into a terminal, it creates 7 detached screen sessions as I expect. If I run it from within a script, however, I get only the first session, "somename," when I run screen -ls.

Edit: If the same can be accomplished another way (e.g. with multiple screen windows instead of sessions), I would be open those solutions as well.

Ubuntu :: Create / Maintain Many Folders?

Oct 8, 2010

I am building an application that would need to store data in many different folders (say, 5,000,000 folders). Obviously that is a big number of folders.

My project is flexible in terms of how to outline the folders (meaning, some folders can be sub-folders of others etc).

Given the Ubuntu file system, is there a rule-of-thumb on how many sub-folders should be in a folder? how many files should be in a folder? (I am asking strictly from a performance point of view).

I am running Ubuntu 10.04 on a Intel X25-M PostVille 160 Go SSD drive with ext4. How can I tell if there's something wrong ? What should/can I do to maintain its performance/health ? Should I use TRIM, is Linux recent support for TRIM reliable ?

This may look as a duplicate of this question, but I am more asking in term of good practices and learning how to use this new technology the right way...

Ubuntu :: Canonical Would Maintain Updates For Only Selected Packages?

May 1, 2010

After reading this announcement, I don't understand if Xubuntu 10.04, or others ubuntu 10.04 variants, will be also LTS. What I understand is that :

- Ubuntu 10.04 (Gnome) Desktop Edition is a LTS.
- Ubuntu 10.04 Server Edition is a LTS
- Ubuntu 10.04 Netbook Edition is NOT a LTS
- Kubuntu 10.04 seems to be a LTS
- Xubuntu 10.04
- Mythbuntu 10.04
- Ubuntu Studio 10.04

Obviously, I can't understand how some variant could be LTS and not some others : they are all using the same repositories. So, Canonical would maintain updates for only selected packages ?Does anyone knows more about that LTS attribution ?

Ubuntu :: Indexing Video File Collection To Maintain?

Nov 27, 2010

I have a large number of video files on a couple of high capacity HDDs. The files are reasonably clearly named. I've never bothered creating a database of the files because I am inherently lazy and believe the computer should be doing this for me.

Anyways, crunch time. Had a look at the stuff in the public repositories, but they all involve too much typing, too much work. So, what are others using/ doing to maintain their "collection" indexes?

Networking :: Unable To Maintain A Wpa Wireless Connection

Jan 5, 2011

I just installed suse 11.3 and everything seems to work perfectly out of the box, except for the network card. I am currently using the ath9k driver.

The problem is that if I connect to a WPA protected network, the connection will drop about every 20 seconds and ask for the network key again. Eventually, after about 15 minutes, it completely stops working and I have to reboot in order to be able to use it again. Unloading and reloading the ath9k module has no effect, a full reboot is needed. I have not yet tried to use ath5k or madwifi instead, but on ubuntu, the ath5k and madwifi drivers do not associate with my card.

below is one "cycle" in the nm log, from connected to the next connected:

Code:
Jan 6 23:37:59 linux-xyz NetworkManager: <info> (wlan0): supplicant connection state: completed -> group handshake
Jan 6 23:37:59 linux-xyz NetworkManager: <info> (wlan0): supplicant connection state: group handshake -> completed
Jan 6 23:38:30 linux-xyz NetworkManager: <info> (wlan0): supplicant connection state: completed -> group handshake
