Ubuntu :: Can't Switch Session Type
May 12, 2010
So, I thought I'd try Gnome as the default session. Using System...Administration...Login Screen, I selected Gnome as the default session.
When I rebooted, I see an ititial login screen, but when I click on anything, all I get is a black screen and a mouse pointer.
So now I am trying to switch back to the default. So I reboot, hit esc and drop into a root shell, type startx, and I get back to the default environment.
Now, however, When I try to use System...Administration...Login Screen, unlock does not work. I also tried by using su to change from root to my regular ID, but still, when I click on unlock in the login screen settings dialog, nothing happens.
How can I correct this? Is there a text file I can edit as root that will alow me to change things back to default?

Is it the way to switch language during the session (probably will reload session)?

I've seen the screenshots and I thought I'd give it a try. I got it off the repos and restarted my system after the installation. But I cannot find it in the Session Type menu in KDM.

I have xdm as my login manager, but I wanted to give some other window managers a try. I currently use Xfce, but I'm wanting to give WindowMaker a try. How would I choose this on login?

I am unable to change session type when not requiring passord on login.
How requiring password was changed:
System/Administration/Users and Groups
Clicked on my User
Clicked "Change" next to "Password: Asked on login"
Checked the checkbox for "Don't ask for password on login"
OK'd, everything
Please try this yourself as it might be hard to understand. But the option to change session type (ie: Gnome failsafe instead of reguar Gnome) is only visable along side with the password field.
Is it possible to make the session type setting visable without requiering password on login?

I installed goblin by run GoblinUI.ymp and logged out.
After I logged out, I chose meego as session type and tried to login again.
I entered correct password, but when I press enter after type password , display change to black and got some message and backed to login session again.
On the other hand, I succeed in running MeeGo Live CD(1.0.1 build 1.4).
I wrote MeeGo Live CD image on USB Flash Driver by using Win32 Disk Imager, and boot that one successfully, although it has some flaw.
Network Settings Window is stuck in workspace and can't move or close, so it cover other appication's window. Internet on toolbar is broken, so I have to run FireFox in application toolbar to use internet.
I'm using Netbook based on Atom CPU and GMA.OpenSUSE installed in my netbook is installed by KDE Live CD image.
Should I Use Gnome to use Goblin, because MeeGo is using Gnome? Or.... what is problem make Goblin doesn't work?

1. I am currently using a basic fedora 14. I had a fedora 8 DVD that contained many packages including its installation (I mean it was bootable and had its iso image. Now my question is that is there any way by which I can install the packages(like OpenOffice.org) from that DVD to fedora 14? I have a slow internet connection and its not possible for me to download large files.
2. I installed some packages via yum. My friend also has fedora 14 but unfortunately he doesnt have a internet connection to download the files via yum and install them. Are the .rpm files downloaded via yum stored in some specific folder, so that I can transfer those files via a flash drive to his computer and install them directly there?
3. Is there a way to autologin my account so that I dont have to type my password everytime I switch on my PC?
4. Everytime and every session I try to access a ntfs partition, it asks for my root password. Any tricks to bypass this?

In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive

I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.
octave:2> test1.m
error: can't perform indexing operations for <unknown type> type
sh: gnuplot: not found
Just to double check my work, I ran the following code:
y=[1 2 3];
plot(y);

Is there a session manager I can use with 10.10? I would like to try Openbox but am not sure how to select it as a startup session. I would like to be able to choose between kde, gnome and openbox.

I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

Can the fibre channel switch in the centOS5.3 cluster edition be switched for a regular router or hub?
If so how would one do this? If not why does the switch have to be fibre channel?

I am putting together some new systems for my customer and I'm having some trouble with a script that we use to back up files to a DVD R. The problem is that I can't write a 2nd session to the DVD unless I eject the disk and reload it. The drives are slimline type drives, Sony BD-5730S and Teac DV-W28S-V93, so they won't reload without human intervention. Opsys is CentOS 5.4 or RHEL 5.4. I've tried both AMD and Intel based mother boards. If i try this on Fedora 11 or 12 it works fine. This works on IDE attached drives but not a SATA attached drives. Fedora appears to use something called genisoimage instead of mkisofs. I can't get genisoimage to run on CentOS or RHEL.
Here's the code to setup the test files:
rm -f /tmp/BDtest/*
mkdir /tmp/BDtest
dd if=/dev/zero of=/tmp/BDtest/blank.iso bs=10M count=1
for NUM in {1..160}

I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.

I am using a Fling KVM switch (by Belkin), to connect 2 computers to my monitor One computer is running XP and the other is running Linux. My wireless switching mechanism has just gone the way of the saints but Belkin has supplied a software solution for this occurrence. There is a small app called Fling (surprising) that allows me to switch from the XP machine to the Linux machine but nothing to switch back to the XP. What I need to know is there a similar app for the Linux computer. (NB I have tried Synergy but have no idea how to set it up - I've been told that synergy might work).

The following message comes up when I boot up: Logging in user Warning: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0. When I press OK, the system completes the start up and everything looks normal. But when I try to connect to internet, I get the following message:
KNetworkManager cannot start because the installation is misconfigured. System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution. KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.
Don't know what info is of interest. I'm using
Opensuse 11.2
KDE 4.4.2 (Factory)
After upgrade from 4.4.1 to 4.4.2 it worked fine for a week or so.

Info about session timeout.
I use tmout = 15 min in my /etc/profile (along with readonly tmout). i have some issues i need to address, looking for ideas.
1. what is considered a idle "session" ?
2. if i & a process to the background and do nothing is this a idle session?
3. if user uses su to a higher level, are there now two sessions? is the tmout for user suspended until su user time outs or leaves su session?
4. i have some users who will run long sql queries. is there a workaround to have the session remain active until process has finished?

Whenever I try to "Switch from [username]..." I get locked screen with the options to "Leave Message", "Switch User" or "Unlock".If I click to "Switch User" the password box just disappears (as if one tried to unlock with an incorrect password). The only thing I can do is unlock the screensaver and resume my login session.I can not seem to switch users.Does anyone know why "Switch User" is not working?

While rearranging my keyboard shortcuts in the control center, I noticed that in the Desktop Switching subcategory, there are "Switch to [Next/Previous/Left/Right] Desktop" and "Switch to Next Screen." What is the difference between switching to another desktop and switching to another screen?

So last night after I got home from the bar I got on my laptop with ubuntu 10.04.
I think I held down the shift key for a while and a message popped up like 'sticky keys' for winbloze.
I hit cancel on the box, but then couldn't type anything after. Not in Gedit, not in firefox, not in openoffice.
I tried holding shift to bring the box back, and no luck.
What to do?

after an update yesterday, I cannot log into my X session ...
The first time I tried, my screen showed a KDE background, and I got the error:
could not start ksmserver check your installation then I had to click ok, and it put me back to the log in screen.
I opened a shell (ctrl-alt-F1), logged in and typed:
sudo apt-get remove ksmserver, and it told me there was nothing to remove, but said I had a bunch of stale packages and to apt-get autoremove them, and I did
Now, when I go to the log in screen (X), under sessions, it only has xterm (no gnome, no kde) ...
[edit]
I forgot to add, I have always used Gnome, and not kde ... I have no idea why it originally tried to throw me into a KDE session
How can I get my gnome desktop environment back so I can log in again? I have no idea what I did, nor how to get back to normalcy!
