Fedora :: Unable To Open The Session

Feb 1, 2010

Just installed Fedora 12 on a P4 IBM. Everything installed fine. Then, I rebooted, installed updates, and installed a few simple programs (emacs, ssh server). I rebooted since some kernel updates had been made. I can't login anymore. I get a brief message at GDM that says "unable to open session" after I enter my password. Root also doesn't work, but I figured out that root logins are disabled. I found something that recommended disabling selinux, so I reboot with selinux=0 parameter. That still didn't fix the problem, but did initiate selinux to re-label everything on the next boot.

My next thought was that maybe my password got corrupted, so I went into single usermode. I ran passwd justin, so I know that my password is correct. I still can't login via GDM or on a tty.

EDIT: I was also thinking I might need to uninstall something that I did; however, networking is disabled in single usermode, and if I init 3, then I get a login prompt that I can't open. Is there a way that I can enable root login? That might be a starting point to see if it's my user account or a general login problem.

OpenSUSE Install :: Cannot Open ConsoleKit Session: Unable To Open Session

Apr 11, 2010

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.

Software :: Unable To Make Ptpcam Working - ERROR: Could Not Open Session

Jun 25, 2010

After finally getting libptp2 to compile I find that ptpcam does not work. This has worked perfectly fine before with the same camera using Slackware 12.0, I am now using Slackware 13.1 and ptpcam will simply not work. The error is as follows:

Code:

x86_1# ptpcam -l
Listing devices...
bus/dev vendorID/prodID device model
ERROR: Could not open session!
Try to reset the camera.

I have tried to reset with "ptpcam -r", I have also tried to disconnect and reconnect the camera to the USB system, I have tried to reboot the computer, I have tried to use different versions of libptp2 -- all to no avail. The strace shows the issue is apparently a failed ioctl(), although I have no idea why it fails:

Code:

open("/dev/bus/usb/002/004", O_RDWR) = 6
write(4, "1"..., 1) = 1
read(3, "1"..., 1) = 1

[code]....

I have verified that the camera is working in Windows 7 on the same physical computer and I can see the camera from lsusb and dmesg output when I connect it to the USB system. This system is Slackware 13.1, Linux x86_1 2.6.33.4-smp #2 SMP Wed May 12 22:47:36 CDT 2010 i686 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux.

Fedora :: Cannot Open ConsoleKit Session

Oct 31, 2010

My Fedora 12 box got that error after some updates on it.

I can login but it's prompting that error and everything will be a black space.

But still no good.

According to the log messages, the ConsoleKit session isn't initializing. I can't paste the logs here coz it's on another laptop.

I could think of just upgrading it to Fedora 13 but there's no way I can backup all of my files on it. Is it just safe to upgrade it?

Fedora :: Virtualbox Error 'Failed To Open Session For Virtual Machine Windows 7'

Jun 6, 2011

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

We are using Real VNC enterprise server. User will connect to the vnc server and do their work. We are facing one issue since from last week. When user is working on session, some times the session will get hung.He can't do anything on that. If he close the connection and try to connect from vnc viewer to the same vnc session it is not connecting. even it is not asking for the password. I have checked in the server the Xvnc process for the session is still running. When I tried to check the session is alive or not from telnet it is not showing that RFB 004.001.

xhdvnc2 ~]# telnet localhost 5902
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).

If users are running some important tasks on that session they are not able to access. We are using RHEL 4U7 .

why the 'at' command can't start screen in the background for me to attach to later?

Ubuntu Servers :: Keeping A Ssh Session Open Forever?

Mar 27, 2010

I stream my local police station dispatch on the web using an icecast/darkice configuration [URL]. The downside of using this software is that once you initiate darkice, a terminal has to be open - the process does not run in the background.

I tried placing a monitor on my server (ouch, that hurt) and keeping darkice alive that way, but my mail server kicks the process. Now, I set the KeepAlive variable to something outrageous and keep an ssh session open on my desktop box to keep the stream going. Screen does not work as Postfix boots that as well.

keeping the process going indefinately?

Fedora :: Unable To Open Https Websites On 10 & 11

Jul 24, 2009

I have installed Fedora 10 and centos 5.3 on 30 system in my home office. everything works fine except accessing https websites. the problem persists in both centos and fedora even after changing firefox versions. what's worse is the problem is not resolved after changing other browsers. so the problem is not browser-centric. i think it has something to do deeper in fedora and centos. also note that i have disabled firewall and selinux but in vain. the problem is still there across all the systems. it's really a show-stopper for me.

Fedora :: Unable To Open Login Screen

Oct 14, 2009

I clean-installed Fedora 11 and everything was running well. I wanted to try Bacula backup program and so I installed the Development package in other to compile Bacula. When I finished the installation, I discovered a bunch of foreign language supports had been installed. I just erased them. While doing so, I must have also erased some other files.

When I rebooted, the bootup process went well until just before the login screen. The screen showed the Fedora logo, f, and got stock there. I was able to login remotely from another local network computer via vncviewer. I found that GNOME dsktop was missing. I logged on to Fedora 11 text mode by issuing CTL+ATL+F3 and did 'yum groupinstall "GNOME Desktop Environment" By remote login from another computer, I determined that the GNOME Desktop had been restored. But the Fedora 11 still stil stuck just before the login screen. What do you think is missing? What do I need to reinstall?
