We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from cdimage. This bug was reported a while ago and there hasn't been any activity in it recently. Vishal Ravishankar, thank you for reporting this and helping make Ubuntu better. Unfortunately it has no way to automate this (no command line interface) and the settings are lost on reboot. It is a desktop app, with a GUI that allows you to tweak all the parameters of a v4l2 device. One such tool is v4l2ucp () which is in Debian unstable but not in Intrepid, I'm afraid. I'm not a C programmer so I can't really take this any further, but it would be a great idea if someone more skilled would expand this into a command line tool that can list all valid parameters for a v4l2 device (plus valid ranges if applicable) and allow setting them, like sound mixers do. Usage example: set_cam_exp /dev/video0 2000 It is thus suitable to be called from startup scripts. To address the specific issue of image too dark I've written and attached a small C program that will set the exposure on a v4l2 device to whatever you want. net) which is in Debian unstable but not in Intrepid, I'm afraid. So it may be that parameters have been removed from the module by choice (I'm suspect), and from now on we should look for userland tools to tweak such devices. V4L2 devices can be fully controlled from the userland. Steps have been taken for a while now to move everything to V4L version 2. On the downside, the "new" kernel drivers lack the module parameters of the "old" driver, and the default parameters make the image very very dark. This is IMHO a good thing, since it guarantees that future kernel releases will carry the driver. AFAIK, Intrepid switched from the "external" gspca drivers to the new drivers that were recently added to the vanilla kernel.
