Hey, I tried my camera logitech quickcam e2500 (046d:089d) with ekiga and its working. As i had read in a thread, i installed libv4l and then used the instruction: LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
However its still not working with gridflow , infact when i select and device #0 to#7 in #camera it causes PD to crash. Now what?

On running dmesg this is what i found: for the camera: [ 11.713178] gspca: main v2.3.0 registered [ 11.724021] gspca: probing 046d:089d [ 11.724024] zc3xx: Sensor MC501CB [ 11.729220] gspca: probe ok [ 11.729230] gspca: probing 046d:089d [ 11.729239] gspca: probing 046d:089d [ 11.729261] usbcore: registered new interface driver zc3xx [ 11.729264] zc3xx: registered [ 11.733789] synaptics was reset on resume, see synaptics_resume_reset if you have trouble on resume [ 11.798591] usbcore: registered new interface driver snd-usb-audio

This is probably related to the ATI driver conflict we just talked about, unfortunately. The quick fix is to make sure Gem is not loaded (nor any other OpenGL thing), but when you actually need Gem to be loaded, it's a bit complicated.
What the conflict does, is turn every error message of GridFlow into a crash. Therefore if you fix this, then you will see GridFlow's error messages correctly and will see what's wrong.
(You can actually see those messages using gdb too, but it's a lot less cumbersome to remove the conflict first.)
