Hello again I haven't update this thread yet (it's my mistake, I have just move it on and on), but I will update it today . It is nice to see, this application has wake interest because I made it mostly for my own need, but I also try to make it usable to others too, of course. Like you probably have already notice, it is now in Extras-devel (and all those updates there are updates to get deb work correctly).

No, should work whitout hacks, just choose correct camera from settings dialog. PyKake uses mainly same lirc config files as is used in shutter widget (exception is Olympus, which uses different remote, to get more functions). All needed files (for Canon, Nikon, Olympus and Pentax) are included in package and you only need to choose correct manufacturer in Settings dialog, which will also be shown when you start the application at the first time). But because I only own Olympus DSLR, I have only tested with it, and there is no 100% proof that it will also work with others (and I already have get some feedback that there is errors with Nikon D90).

Have you set the camera itself in Bulb mode? Because in pyKake Bulb mode is only a front-end which includes shutter button (named as "Bulb on" and "Bulb off" depending the status of button press) and timer + Time add button. It will also play some nice little sounds (when counting up, it uses time interval selected in Settings dialog to play beeb sound and when counting down it will play alarm sound when time is up). Anyway the Bulb commands are just basic shutter commands (exception in the Olympus, which has own special commands), so you need to check from cameras own manual how to use bulb mode in it (example in Olympus e-420 you can take bulb photos only in M-mode, when you have set shutter speed in "BULB", the longest one) and this guideline works also for the normal use of remote, pyKake will not automatically set your camera in remote/bulb mode, you had to do that yourself (and best way to find how to do this is read the cameras manual).

There is no feedback system in current version of pyKake, but it will be added later, it is major "bug", because I didn't need those (all debug and testing is done in X term, so all warnings and messages comes in there too), so I forgot to add them, sorry.

I will update the first post of this thread with better instructions and small changelog as soon as possible (it will take 1-2 hours from the moment I post this one).

And because pyKake is in Extras-devel (and even it should be perfectly safe to install, use and remove it), I will put this warning message here :
The software hosted in extras-devel is not ready for normal users!PLEASE PLEASE PLEASE don't play with it unless you really know what you are doing. Be ready to file proper bug reports instead of posting complaints. Expected problems: crashes, battery drain, poor system performance, full disk space & more - SERIOUSLY!

Don't play with Extras-devel if you haven't backed up your data or aren't prepared to re-flash your device.
