Slack 12.1 KBluetooth crashes - BlueZ comms one-way only

bogzab · 05-20-2008, 04:19 AM

I had Bluetooth working fine on my laptop with Slack 12.0. After upgrading to 12.1 (everything else seems to be fine), KBluetooth crashes on startup and my laptop seems to be undiscoverable to most other BT devices (but not to my phone which finds it OK!). I cannot send files to the laptop even from the phone that can find it - when I try I get a "sending failed" message. I can send files from the laptop to other devices - the KDE OBEX push client seems to work fine and discovers other devices fine. "hcitool scan" also finds other devices.

The KBluetooth crash is described in various postings (not just Slackware by any means) but I have not found a fix for it anyplace. The non-discovery of my laptop by other devices may be unrelated and requires a fix in the hcid.conf file but I cannot see what that fix might be after looking at the man files.

I will post to KDE forums too, but have any Slackers had a similar problem? Found a solution?

Thanks

I ran into exactly the same problem. The fix for me was to recompile KBluetooth with the Slackbuild script from Slackbuilds.org. I don't know what changed between 12.0 and 12.1, but it sure did hose KBluetooth.

Thanks - solved it. I was about to re-build KdeBluetooth anyway, but you reminded me to do the proper way - with a SlackBuild. All done and bluetooth file transfer working both into and out of the laptop. I did not realise that the KdeBluetooth package actually supplies the obex client.

I've got a big fail on this one - KDE Bluetooth with both the Slackbuild and a package from Slacky.eu. They crash big:

Code:

Still, it gives me a Bluetooth system tray icon, but with the apps greyed out. When I run Kbluemon, I get something similar:

Code:

$ kbluemon 
mainDEBUG

kbluemon: [KBluetooth::DBusSignal::DBusSignal(const QString&, const QString&, const QString&, DBusConnection*)] : org.bluez path:  interface: org.bluez.Adapter conn: 0x8107298
kbluemon: Adding match failed: org.freedesktop.DBus.Error.MatchRuleInvalid: Path '' is invalid

This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace

This also yields a crash dialog.
Any ideas?

You might want to start a new thread on this one to get more exposure. I haven't upgraded to 12.2 yet so I'm not going to be much use. However, it sort of looks that those errors are being caused by HAL. If you recently upgraded, you may want to make sure you re-read the CHANGES AND HINTS.txt and UPGRADE.txt because I think there were some special precautions you had to take with HAL.

I agree with Hangdog that you might start a new thread. For the record I have never got KBluetooth working 100% with Slack 12.1 (despite a posting in this thread which says it was OK once I got the Slackbuild installed. I have now failed to get it working on two PCs with Slack 12.1 - a laptop and a desktop, the latter after a 100% clean install following complete re-build of the PC. On both my machines KBluetooth starts but shows no bluetooth contacts in its main konqueror window. If I send a file to either of these PCs via Bluetooth a KDE window pops up just fine and allows me to save the file - so BT contacts are made - it is just the display of devices in the KBluetooth window that fails.

I was hoping that an upgrade to 12.1 might fix it and it still might for me I guess.

Uh? What? Bluetooth working on Slackware? What are on Earth these people talking about?
