CentOS 5 :: Starting VirtualBox Causes User Session To Logout?
Feb 17, 2011
I have installed VirtualBox as per the instructions on this site, and the kernel module compiled without problem, however when I start it, it causes the user to logout!
I am using the nvidia module from the ATrpms repo if that has any bearing on the problem.
Has anyone else seen this issue?
Details:
CentOS 5.5 x86_64 running on a Dell Studio XPS 435MT with i7 920 and 6GB of RAM
VirtualBox 4.0.2 from virtualbox repo.
nvidia driver 260.

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 Fedora 11 + kde 4.3.1 + compiz. for several times now my session ended unexpected, I can't reproduce that behavior and so I am looking for a log or someplace to look after such logout to find out what caused or triggered it.
I saw another thread about unexpected logout while browsing, its not the same although it happens to me so far while using firefox / mplayer / Kontact (kmail) .

I sshed into a Linux machine (bash shell) from a public Windows machine (in our lab) and forgot to log out. I'm now back at my seat in another room and I am too lazy to walk back and log out that session; I can ssh into the Linux machine from my current PC though. Can I force-logout the other session from a new SSH session?
When I ssh to the Linux box from my current PC and type users command, I can see that I'm still logged in there; my name is listed twice - one for the current session and another for the session from lab PC.
I don't have root privileges on the said machine, but I guess that shouldn't matter as I'm just trying to log out myself.

I would love to auto-start tomboy at startup. How can I do this ? [Moderator edit: fixed Subject so nobody would expect an automatic Lunch. Is that the same as a free one? ]

Where has the possibility to auto-save session on logout gone in 11.04? Or even just save a session at any point?It has been filed as a bug on URL... but I fear it has been (re)moved on purpose..

I'm trying to run Slackware 13.37 64-bit in a VirtualBox virtual machine. My VirtualBox version is 3.2.12. I had to disable compositing to keep the X-Server from reporting a segfault.Now the problem is that on logout from KDE I get a completely black screen. I can switch to a console session and type commands to get the login screen again.
telinit 3
telinit 4
I tried editing "kdmrc" to add the line "TerminateServer=true" but it had no effect on the problem.I had this working with Slackware 13.1 at one time, but I can't seem to get it working properly now even without desktop effects.I'm trying to avoid changing my VirtualBox software since each version seems to just introduce new and different bugs. The 4.X versions are not yet very stable.

For some reason the shutdown/hibernate/logout options has disappeared from the Indicator session. I can still set my status in EmpathyI have tried reverting to gnome panel defaults (gconftool --recursive-unset /apps/panel && killall gnome-panel), removing and readding and I've checked synaptics and it seems I have everything indicator-related installed.

So after a series of uninstalling and reinstalling VirtualBox to get the updated version, I was able to get it installed and working but it seemed to be crashing my computer as everytime i walked away for 10 minutes and came back, it would be at the login screen. It never did it while I was on it though so I never saw any errors. Now after a couple days of that... Whenever I start it I get an error:
Failed to create VirtualBox COM object
The application will now terminate.
Could not load the settings file '/home/user/.VirtualBox/VirtualBox.xml'

On a fresh install of the Meerkat release candidate, I've installed the latest VirtualBox (3.2.8-64453, not open source version). When I run it, I get a user-agreement notice box as expected.
But, (1) sometimes immediately thereafter, or if not, then (2) as soon as I move the mouse pointer or (3) after I use the PageDown key to get to the bottom of the agreement text and use a key combination for "I agree," my Ubuntu user session crashes and I have to log in again.
The only other weird symptom I'm having is that I cannot set visual effects to anything but "None" (if I attempt to, I get an alert "The Composite extension is not available").
Perhaps there's a video-related problem underlying both issues, i.e., the X server is failing in both cases?

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}
[Code].....

My normal day to day user can't shutdown, restart, logout, etc...It just doesn't do anything at all when I try. This wasn't the case three days ago, just fresh installed and seeing the same problem (so it must be some setting saved in my home folder which wasn't wiped).

First off I'm running Ubuntu 10.10 64bit, if you would like a complete discription of my hardware you can find my lshw > [URL]I seem to have broken my VirtualBox installation, I went from VirtualBox OSE to VirtualBox 3.2 (again 64bit version downloaded from virtualbox.org the about says version 3.2.10 r66523) I tried apt-get purging 3.2 and going back to OSE but it gives me the same error I started getting when I tried installing 3.2 so I have decided to install that again and try and trouble shoot the problem.I get two error windows that pop up when I try and start my windows xp virtualbox, the first says:

If I start my VirtualBox on Ubuntu 11.04 it crashes 50% of the time... The whole system hangs, even the music keeps playing the last 2 seconds over and over... I can't find useful information in the Log File Viewer. I'm using seperate X screens, maybe it has something to do with that?

If, as root, I 'Leave' --> 'Logout', I get the KDE login screen.If, as user rob, I 'Leave' --> 'Logout', I get a black screen from which I must power off to recover, and I use the term very loosely. User rob is a member of the 'power' group.

I'am using gentoo linux. After some system's updates VirtualBox stoped loading any virtual machine with error:
Code: Failed to open a session for the virtual machine. Virtual machine has terminated unexpectedly during startup.
Details:
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Machine
Interface: IMachine {99404f50-dd10-40d3-889b-dd2f79f1e95e} Kernel log
Code:
So, i've rebuilded all VirtualBox dependencies with safe flags, then i've recompiled most of the sys-* packages also with safe flags. However VirtualBox still doesn't work.
UPD: virtualbox-bin-3.1.4
UPD2: 3.1.6 and ose-versions crashes with same errors

Slack 13.0 X sometimes fails to start after boot about 50% of the time. linux says "starting X11 session" then I get a blank screen with a flashing cursor and absolutely nothing else. I can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. After that, I can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. I have reinstalled X and KDE twice now as well as deleting my .kde folder. This condition started when I inadvertently ran out of disk space on my /home drive. Since then I have migrated /home to a larger drive and watch it's disk space very carefully.

I download "VirtualBox-3.1.2-56127-Linux_amd64.run" and installed it, and got a messages like this " virtualbox have been installed successfully in my system", but when I run virtualbox, I've been told "/etc/init.d/vboxdrv setup" something like that. And I run virtualbox in terminal, got this:
Warning: The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (2.6.29.6) or it failed to load. Please recompile the kernel module and install it by
sudo /etc/init.d/vboxdrv setup
You will not be able to start VMs until this problem is fixed.
I run "/etc/rc.d/rc.vboxdrv start" as a root, got messages like this :
Starting VirtualBox kernel module ...failed!
(modprobe vboxdrv failed.)

I downloaded the ADT bundle for android development and whenever I try to boot an Android Device Emulator either from the eclipse version included in the bundle or from the command line, everything freezes for 1 minute and then a logout from my current Debian user session occurs. In other words, the Debian login screen appears again and all my previously opened applications get lost.
Not even when I run from the command line I manage to fetch any error notification.
I use:
- Debian Wheezy
- kernel 3.2.0-4-686-pae
- jdk1.7.0_09
I tried
./emulator @mydevname -no-boot-anim -show-kernel -shell
but I get the same result: the debian user session restarts

I have Lucid setup for multi user. Whenever 2 users are logged in and one logs off, it freezes on a black screen. It looks like it logs off OK and is on its way to the main login screen but never gets there. I found some older posts describing this problem but no solution. I tried to post to that thread but got a message saying I was not permitted. I am new to Linux and am struggling to figure out how to problem solve issues in Ubuntu.

I have a strange problem with some applications in 10.10. This applies so far to virtualbox and skype. When I try to start them, nothing happens. Virtualbox just flickers the edge of the screen. Virtualbox has worked before, and i'm reluctant to delete it as I have another machine installed. Skype has never worked, and even when I have reinstalled, the same happens.

When i try to create a virtual machine using the Windows 7 Enterprise Evaluation iso file, everything goes as planned untill i click on the start button. when i click on it i get two error messages. the first: Failed to open a session for the virtual machine Windows 7. The virtual machine 'Windows 7' has terminated unexpectedly during startup with exit code 1. Kernel driver not installed (rc=-1908). The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. reinstall the kernel module by executing
'/etc/init.d/vboxdrv setup'
as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. i have installed the DKMS package, but when i try to run the command stated in the error message, i get another error message in the terminal:

i have to install the driver that is specified (vboxdrv) but i do not know where to find it.

As a normal user I have activated the functions of the Quit applet, i.e. Logout, Shutdown and Restart are active buttons. I am able to restart or shutdown, no problems. But when I use the Logout button I don't get logged out, just returned to the login shell & I am still logged in as my user. I don't have a display manager installed and I do NOT want to use a display manager such as XDM or GDM. How do I get the Logout button to actually logout the user? It appears I am only getting logged out of the x-session, but I want complete logout.

My ISP offers the service of native IPv6. So my ADSL router provides me with a local and global IPv6 address. However after a reboot it takes minutes to finally see the global address when using "ifconfog eth0". During that time I can't do a ping6 to an external server, which seems logical. So I waited several minutes, but no global address. After that I started a KDE session, went back to the console(<Ctrl>+<Alt>+F1) and now the global address was there. Is this normal behavior or should I file bug report?

I managed to install Centos x86 for the first time, together with VncServer, SSH access, mySQL and Apache. Everything worked greater until I logged in remotely to the server from my Windows 7 machine using RealVnc. I manage to connect successfully and able to use the GUI remotely. However, when I press logout from the menu, the screen gets stuck on the funky blue and white curly background. It does not close automatically.
If I close it using the 'X' button and reconnect, I get in to same stuck screen. My only workaround is to login with Putty and type 'service vncserver restart'. Then I am able to connect again. But same thing happens when I do a logout.
