X server already running error on bootup

[jabrown65]

I using mythbuntu Intredip with all updates install.

Since the last update mythubuntu stopped booting up properly. Instead of mythtv frontend, I get the desktop with a message saying that the last session lasted less than 10 seconds etc. with the option of "Viewing Details". If I don't view details then it quickly drops out to a login screen. If I do view the details can use the desktop, for as long as I leave the details displayed. Once I close the details it quickly drops out to the login screen.

The 'details' are:

I tried reinstalling networkmanager and nm-applet, but the problem remains. Similarly, I have tried updating again to no avail

I have been searching using google and can't find anything on the problem

Have others experienced this?

As I said, it was working fine before the my last update.

Ideas?

In a Mythtv forum, someone else had the same problem with the Mythtv backend, as did I. I note that Mythtv uses OpenGL, and if I try to compile a trivial OpenGL program, I get a segmentation fault. I suspect that the problem is with the Nvidia driver. I am using an Nvidia Geforce 6200, and the generic nv driver.

Thanks, but my hardware is an EPIA EN12000 motherboard using the onboard VIA video and hardware accelerator, so no Nvidia or OpenGL involved. Also, it is a fanless mythtv frontend which accesses the backend via a wired gigabyte ethernet network. The backend is working fine, as is a Ubuntu frontend running on the same EPIA frontend in a different dual boot partition which hasn't been updated.

(I always have two installations on the frontend to make sure that at least one is always working. This means that whatever happens I can always watch recordings! One installation is Mythbuntu and the other is Ubuntu. Currently the Mythbuntu partition is not working, and the Ubuntu partition is not being updated or changed until I get Mythbuntu working again. I highly recommend this strategy! The rest of the people in the household greatly appreciate it!)

Same issue here; it seems to be specific to compiz for me. I tried uninstalling NetworkManager & got segfaults from compiz anyway. There is a workaround I found somewhere (don't click on the "OK" button in the dialog box), so it's merely an annoyance.

Here's my .xsession-errors. Note I suspect the segfault message at the end is from compiz, but can't say for sure:

Solved. I did a little more digging & found this in dmsg:

[27856.597170] xfce4-session[16168]: segfault at b72932f8 ip b72932f8 sp bf9c03c0 error 4 in LC_CTYPE[b7299000+3f000]

Then I found this:

http://ubuntuforums.org/showthread.php?p=6330684

and tried getting rid of the old xfce4-session.rc as described:

[18:33:54 curtis ~]$ mv ~/.config/xfce4-session/xfce4-session.rc ~/.config/xfce4-session/xfce4-session.rc.old

Logged out & back in again; everything's fine & dandy. HTH.

Yep, getting rid of the old xfce4-session.rc as described worked for me too! Thanks!
