Software :: Multiple Concurrent Remote Desktop Sessions?
Feb 28, 2010I 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.

Jul 11, 2011I'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 Installation :: Shows Multiple CPU Overtemp Messages And Freezes With Totally Black Screen
Jan 20, 2010I burnt the Ubuntu 9.10 ISO to CD and installed on a freshly nuked Dell 2350. It is pentium 4 at 1.8 MHZ with 512 RAM. Just a spare machine I have sitting there. Install went fine, restarted box, boot from hard drive. I get the little white Ubuntu symbol on a black screen and then a black screen with un-occupied white tool bars at top and bottom of screen and a functional mouse pointer, then nothing. It freezes there.
If I restart by holding the power switch in it occasionally shows multiple CPU overtemp messages and freezes with totally black screen. I can run the CD live and everything works like a champ. I'm going to like Ubuntu once I have this sorted out. If I boot from CD and choose the run from first hard drive option, everything loads and works fine. I was able to remove CD, update and save preferences, etc..
On one occasion, I was able to restart and boot from hard drive and it worked fine but usually it freezes at previously mentioned black screen with white bars top and bottom with mouse pointer. Please excuse my ignorance as I have very little knowledge of the inside workings of computers. I didn't even know about burning ISO's or changing boot orders until reading online. For what it's worth, the computer worked fine with no known hardware problems when it was running XP. It also is completely stock with no mods or added/replaced hardware.
Ubuntu :: Black Screen (no Desktop) On 10.04 LTS
Jun 20, 2010The computer was working fine last night, when I woke up this morning (I leave it on) it was making strange noises through the speakers and I had a blank screen, restarted a few times had some page full of code and wouldn't move on from there, I went out came back started it up and it did everything normally except instead of a desktop I had a black screen, however strangely enough when I press the power button on the PC a shut down menu comes up, and the mouse works and I can select from the options. I am on an Nvidia ION tho. How do I boot into a safe mode as such? as at the moment I'm using a ubuntu live CD to read the forums!
On the GRUB menu, seclect "Ubuntu (recovery mode)" (not exact wording). You'll get scrolling boot messages until you get to a screen with a grey box and some options. Use the arrow keys to select "x failsafe graphics mode" or something of the like. Press enter and you'll probably get a message that your card can't be detected or something. Press okay and continue. Your screen will be messed up, but you'll be in. It probably isn't the same problem, as you don't have an ATI card and can see a shutdown menu, but good Luck!
How do you bring up the GRUB menu? My PC isnt dual booted so I never see any menus at all, I thought all I had to do was press F8 during boot up? No, F8 is Windows. Hold down shift when booting to see the menu. Downloaded & Installed the 10.6 driver and everything is working fine. Unminimizing apps works much faster with this driver . However, /usr/bin/aticonfig --initial results in
Code:
Found fglrx primary device section
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-2
/usr/bin/aticonfig: Writing to '/etc/X11/xorg.conf' failed. Bad file descriptor.
Right now I've tried what "jxtreme" suggested on quote nr2 however when I go into recovery mode I get a load of code scrolling through the screen as its supposed to but I never get any box with options as he says, it just gets to a point where there's a small white cursor flashing at me half way down the screen and it stays there...

Ubuntu :: Will It Be Possible To Maintain Multiple Sessions
Oct 4, 2010Will 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 Installation :: Black Screen - No Visible Desktop
May 20, 2010I have a problem after installing Debian and running it on my machine. Instead of taking me to a splash login screen, it instead remains a black screen like a console where I type in my username and password, and it remains in this black command line mode beginning ben@ben-desktop:~$. Like it does in a terminal. What can I do to resolve this? This is completely new to me and hasn't happened to me in Ubuntu or Mint. I am familiar with using the terminal for the odd task but obviously I can't use it like this without a visible desktop.

Sep 14, 2010Trying to install Ubuntu 10.04 desktop (amd64) on this brand new system:
I connected the Dell ST2410 24" Full HD Widescreen LCD to the HDMI port on the ATI card and Windows 7 boots up just fine.
So then I put in the "ubuntu-10.04-desktop-amd64.iso" CD in drive and reboot the system. I see the Ubuntu logo with the dots for a while and then the LCD goes black. The LCD reports that there is no signal from the system. The power light in front of the LCD goes from white to amber. The keyboard stops responding.
I power off everything, remove the Ubuntu CD and reboot the system and it works fine again with Windows 7.
The CD has no problems. At boot time, I checked it for defects and it reports no errors. At boot time, I used this same CD to check the system for memory errors. No memory errors. I used the same CD to install Ubuntu on other systems and had no problems.
The 16X DVDRW Drive has no problems. In Windows 7 it can play CDs and DVDs.

Debian :: Multiple Sessions With X Window

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.

View 2 Replies View RelatedUbuntu :: Multiple X Sessions - Auto Login 2 Different Users
Oct 11, 2010I 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, 2015I 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?

View 14 Replies View RelatedDebian :: Iceweasel - Secure Sessions On Multiple Profiles
May 18, 2010I'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, 2015Running 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, 2010Here'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.
