[Bug 1198610] Re: Black screen while trying to disconnect from Bluetooth DUN connection
Muhammet Aklan, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc2
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
Black screen while trying to disconnect from Bluetooth DUN connection
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Hello.
The release of Ubuntu I am using: Ubuntu 13.04
The version of the package I am using: 0.9.8.0-0ubuntu6
I am using a Dell Inspiron 5520 laptop. And in order to connect to the
Internet, I use my Samsung SGH-L700 phone as a Bluetooth modem. When I
try to connect to the Internet via Bluetooth DUN connection using
Network Manager applet, there is usually no problem. But when I try to
disconnect,
What I expect to happen: The connection should be terminated and the
system should go on working normally.
What happens instead: Suddenly, a black screen with full of text comes
up. Sometimes (not always) a "panic occurred" message with a blinking
Caps Lock light can be seen.
Additionally, after establishing the connection, the name of the
connection isn't viewed on the applet's drop-down menu as it should
be. Sometimes there is a strange character, sometimes the text "Empty
tag", sometimes a text that is not about the connection's name such as
"org.freedesktop. ..." or "Connect to a Wi-Fi _network" is seen
instead of the name.
Before reporting this bug, I opened a topic on Ubuntu Turkey Forum. A
forum moderator recommended me to file a bug report about network-
manager package on Launchpad. So I filed a report here. This is my
first bug report.
Thanks for possible solutions in advance.
