Thanks for your interest in the Intel® Realsense™ Platform.
I'm sorry to hear that you are having issues with SR300. Could you be so kind to provide me your system information file, this in order to check your computer hardware specifications. If you don't know how to generate it, please press on your keyboard WinLogo + r, then enter msinfo32, then click on File >> Export. This process might take some minutes, once you have generated that file, please send it to us in your next reply.
Have a nice day!
Sorry to be too late. Unfortunately, I do not have PC with windows OS. I am working on ubuntu 16.04 LTS.
It was working prefect but suddenly the problem happened and the depth camera does not work well anymore. No hardware damage happened to it at all. The RGB camera works.
Don't worry, we are here help. If you only have Ubuntu on your PC, is going to be hard to troubleshoot your issue, since all the guides are designed using Windows OS.
I would encourage you to use librealsense GitHub - IntelRealSense/librealsense: Cross-platform camera capture for Intel® RealSense™ F200, SR300 and R200 if you are going to stick with Ubuntu or the other option would be to partition your disk and install Windows alongside Ubuntu.
In case you install Windows here are the guides to troubleshoot your camera: (Be careful with the new Windows OS version (Windows* 10 Creators Update Build 15063 Is Not Compatible with Intel® RealSense™ SR300 Camera Driver ))
Have a great day!
