Ubuntu :: Guest Session: How To Configure And Available From Login Screen
Jan 8, 2010
I like very much the Guest Session feature of Karmic, it comes very handy when someone needs to use your computer. However, it's only available if I'm already logged in, it won't show this option at login screen. Is there any way to make this possible? Also, I once tried the guest session and configured its appearance to my taste. The next time I entered, though, the default desktop reappeared. I know this happens because no setting is permanently stored for this session, so the only solution I can think of is to change the default configuration it is loaded from.

I learned how to do this on the 'net somewhere. This HowTo will help you create an account on the login screen that will log in the same guest-session seen in the user menu. The advantage of this is that it will be an easily accessible guest account, while not preserving any files or changes on logout, and a higher security model for the account. Confirmed to work on 10.04 - 10.10, but the directions are for 10.10
1. Under an existing administrator account, go to the menu entry System --> administration --> Users and Groups.
2. Click Add. you may need to provide a password at this point. Name your new user anything you would like, except guest. The account cannot be called guest, but visitor does nicely. encryption of the account is not needed. This account will be a "booster" account to guest-session.
3. On the next screen, enter a password, and make sure that you click the check box "Don't ask for password on login", Click OK to finish.
4. As an extra precaution, click Advanced settings, when back on the Users and Groups screen, and on the User Privileges tab, uncheck Monitor System Logs.
5. Exit the Users and groups menu, and then log out and into your new account.
6. Once there, make a folder called GuestManager, and in that folder, make a plain text file called Guestmanager.sh, with this code in it :
Code:
#!/bin/bash
# Launches the guest session
/usr/share/gdm/guest-session/guest-session-launch
# Logs the user when done
/usr/bin/gnome-session-save --logout
7. Save that and then right click on it, go to properties, and then go to the permissions tab. On this tab, click "allow executing file as program", and then close that window.
8. Open the menu entry System --> Preferences --> Startup Applications, and once there, turn off all the startup applications, and then click add. Fill in the name and comment as GustManager, and for the command, enter /home/visitor/GuestManager/GuestManager.sh, where visitor would be the name you picked for the account in step 2. click add, then close
9. Delete all applets and extra toolbars (might want to leave the main gnome menu), and set the background to black or something else bland, and log out. Since this account is just a "booster" none of these toolbars and such will be needed, so removing them saves memory and load time.

i am wondering if it is possible to do this all i can find with google is idea proposals and brainstorms i know i could make a separate account and call it guest user bu that user would get to keep data/settings where as a guest session places a temporary account in the /tmp folder which combined with a ram disk for /tmp would result in some really fast performance since i use a ssd for / which would make the traditional hdd only used for /var also since /tmp would be a ram disk it would be like the guest is using a live cd with security restrictions and performance enhancements on top of this there would be no trace of the guest on my computer after shutdown

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

Adding Firefox add-ons to Guest Session?I wanted to include Add-on to Ubuntu Guest Session Firefox.Is there a proper or better way to do this? Procedure I used was as follows
1. Login to Ubuntu to a user account with sudo privileges (later sudoer account).
1. Switch to Guest Session
2. Install relevant Add-ons
3. Check what the home folder of the Guest Session is. It should be something like /tmp/guest-home.xxxxxx where xxxxxx = six random characters.
4. Switch to sudoer account
5. Open terminal and type
Code:
gksudo nautilus
[code]....
I tested this with Flashblock and it seemed to work. I also admit that since I did the thing for the first time it was not that straight forward for me, but above procedure should work. With quick Googling I was unable to find straight forward method. There is a way to install Add-ons to all users from command line using -install-global-extension but this was not what I wanted to do. I wanted the Add-on just for the temporary guest account.

At work, we have a linux machine which is shared among the members of my team. Each of us runs an XServer on our desktop, which allows us to launch XClients (xterm, debuggers, etc) on the linux machine.We all are using X11 forwarding feature with SSH. I personally run all shell sessions behind screen because I like to be able to detach if needed. We've seen issues when the $DISPLAY variable gets crossed between different users. Let me outline a series of events:
1. user1 logs in and $DISPLAY = localhost:10.0
2. user1 launches a screen
3. user1 loses connection to linux machine (eg. desktop reboot)
4. user2 logs in and $DISPLAY = localhost:10.0
5. user1 logs in and $DISPLAY = localhost:11.0
6. user1 resumes screen from previous login, but in this screen $DISPLAY=localhost:10.0.
7. user1's X apps get displayed on user2's desktop!
I assume someone must of encountered this before. Are there any known solutions? Is there a way to configure screen, so that when a session is resumed it inherits the $DISPLAY?

After upgrading my netbook (Eee 1005HA) from Ubuntu Lucid to Maverick, I can log in okay, but it crashes back to the login screen a couple of minutes after logging in, after the desktop has loaded. I haven't been able to find anything in syslog/dmesg/etc. about why this is happening, but it isn't happening on my other laptop which I just upgraded to Maverick as well.
Edit: memtest86+ showed no errors and the live USB desktop works fine.

I'm going to start with Gen'l Help then maybe slide over to security. Twice recently, when shutting down for the night, I've noticed a Guest Session has been activated on my system. Since I'm the only one using this machine, I'm naturally curious. Can anyone out there explain how Guest Session works and if it can be activated remotely... or otherwise explain how the check mark next to "Guest Session" might be activated?

Ubuntu 10.10 x64.It's been a little over a week since I *rebuilt my system after a gdm or gnome issue and now I'm having an issue with the guest session not working and I'm unable to add a new user. It says "incorrect data" or something like that. This is more than annoying. Why is my system decaying so rapidly? I'm not adding anything to the system that isn't approved by Ubuntu. it's virtually a stock build, minus some changes to the look and feel category. Is this possibly a security issue? My routers up and running and I turned on UFW.
.1) Can't add new users
.2) Guest session will not start.
.3) Should I be concerned about my security?

I noticed (the hard way) that enabling a guest session under 9.04 does not lock the source user. I enabled a guest session for someone and came back to find them rooting through my files. By quitting the guest session, it goes back to the source user's desktop without requiring a password. Shouldnt it go to gnome-screensaver automatically? Can this be changed? Is it a bug?
to replicate: log into source user's account use the menu to start a guest session quit the guest session root through files un-opposed.

I am posting this in the "Desktop Environments" section on the theory that the VirtualBox is indeed a desktop environment.
Bottom lines first - maybe it will make the whole essay below superfluous. Do I need to use the Windows-7 installation disk to install the "guest" OS into this virtual box? (This is the main question.) I suspect it is, after the prompts I get trying to run my guest OS for the first time. Since I have a dual-boot anyway - with Win-7 as the main OS on the machine - is there any way I can configure Virtualbox to use the existing Win-7 installation as a guest OS, without damaging the Windows partitions?
Now the rest of the story:
I just deleted about 100 lines of torturous details, realizing nobody will want to read through all that. 1. Question 2 is optional - I have a 400GB mounted file system on a huge Seagate drive for my guest "hard drive".

My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.

I just downloaded the latest version of Ubuntu and went to install it on a Pentium 4 desktop that previously had XP on it. I get the main setup screen where it allows you several options including installation. Once I select installation, it appears to be installing but then comes up with a message that includes the following: "removing gdm-guest-session" It will not do anything else and the machine appears to go into sleep mode. When I try to shut it down, it appears that the kernel had loaded. Any ideas why the normal installation isn't continuing?

I spill my soda on my keyboard and ended up in a 4 day war with my pc.Now my tab, capslock, left shift, and down vol no longer works. I'm going to take it into the shop in the next couple of days to probably replace the keyboard. (If only lenovo kept the easy access keyboards like ibm had on the thinkpads). Something tells me that they will want to log in and test out the keyboard. So I created a guest account with a simple password. I changed my normal user home dir to 770 permissions and changed guest's shell to /bin/rbash. (both found in other posts.) Is there anything else I should do to secure the computer while it is in the shop?[I use su, sudo isn't configured to work (its a dependency so I can't uninstall)]. I have a pretty decent root password.

i need to build a pc, that allow to everyone to use it, and that does not "save" nothing (a guest volatile session)
i see the xguest package, looks good, but has 2 big problems:
1) seems not possible to customize the session (eg: modifying the home), and this one is not so a big one
2) is impossible to choose a localization: with the fedora login screen it is possible to choose the localization only after clicking on thje usernname, but using xguest, if i click on the username starts promptly the session
so i'd like to ask if is there any workaround for have that "volatile" and better if customizable home i thinked , IF possible to copy an home folder to /tmp (if possible and use the /tmp instead the home during the session, obv with enough available ram) OR copy a home from a user to the"GUEST" one at the start (boot, or login), then delete it at logout or turning off the pc

I have installed VirtualBox and setup a Windows Vista host, initially with a .vdi of 10gb. That filled up quickly, so I added another 20gb secondary partition, after first trying to allocate a .vdi to a SCSI controller. Configured the drive in Windows (Computer Management), and all seemed ok. I shutdown VB, and rebooted my Linux host (openSuse 11.3). Now I keep bouncing back to the login screen, and can't login to Linux KDE, but can login to a console.I do have the following info:
/etc/fstab:
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part5 swap swap defaults 0 0
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part6 / ext4 acl,user_xattr 1 1
[code]....
I did see a message before, that I don't see anymore, that said it could not start NFS services due to missing entry in fstab. Another I'm seeing now is it couldn't start the avahi-daemon, no space left on device. This is odd, since I have a 200GB drive, with half of it left, only max 30GB set to VB. Here's my df -k output:
/dev/sda6 Use% is 100%
devtmpfs Use% is 1%
tmpfs Use% is 1%
/dev/sda7 Use% is 46%
So root "/" is mounted on /dev/sda6, which looks like it could be a problem, but why would this suddenly be a problem after working with VirtualBox? Could this be a matter of just freeing up space on /dev/sda6? Like the /tmp folder that's under "/"?

I need some help install and configure my vnc session at my Opensuse.
Right now I have installed nx client which works fine and is listening on port 5901.
I also want vnc to use when I want to check exactly what is going on my work's computer (when I go home)
I am reading the tutorial here:
And I would like to ask you the following
1.
Code:
For VNC client connection remember to open ports 5901-> in the firewall. (1 port/Xsession.) nxserver is listening to 5901. How to configure vnc to listen to 5902.
2. The guide also refers that
Code:
Here we "Prestart" vnc sessions for specific users, therefore no login screen is presented. This uses more resources as the VNC Session is running even when no client is connected to the session watching it. But there in lies it's advantage, "watching a session" and "using a session" are not the same thing! This method is very usefull for starting long running programs before going home. Once home you can re-connect to the session and see how things are going.

I have a desktop running Hardy and till friday it was running good. Today is monday and I guess it has got monday blues like I get every monday at work.Today I tried to start it as usual but it just refused to go further than login screen. I just can not login. It just hangs it there. I do not know what has gone wrong. I did not change anything since friday and no one else uses it. Theres nothing in logs that could give any idea. It just hangs without any reason and is still on the login screen for ever. It does ask my username and password but then it does not go further.But to my surprise I tried logging in with root and it gave me expected error that system administrator is not allowed to login from gnome.

I'm trying to get samba working on a debian/xebian box to use as a fileserver. I have a HTPC which is win 7 and a laptop which is OS X. I've installed SWAT and Samba to manage the whole settings. I'm trying to get it setup so that there's a user which has access to my ~/ and a guest user which just has read access to ~/Media/ so that the Media centre can read all the files from it without having to login.
The problem is when I have map to guest set as NEVER I can access the samba ~/ and I'm asked for a username and password which I login with fine and can access the files on both share ~/ and ~/Media. However when I set the map to guest to bad user or bad password I can access the share for ~/Media. But when I try and access the share ~/ I don't get any login box and I immediately get the error "Can't access share permission denied" or an error along those lines.
Here's my /etc/samba/smb.conf
# Samba config file created using SWAT
# from 192.168.1.65 (192.168.1.65)
# Date: 2010/07/10 20:39:16
# Global parameters
[global]
workgroup = MS_HOME
server string = %h server (Samba %v)
obey pam restrictions = Yes
passdb backend = tdbsam, guest
passwd program = /usr/bin/passwd %u
passwd chat = *EntersnewsUNIXspassword:* %n .....
How to get it working so I can have a guest share for my HTPC and a logged in user for my private files?
