I'm having an issue with my Ubuntu machine that I can't seem to find the cause of.
After I login to Ubuntu with my password the screen goes black for 3 to 8 seconds or so before displaying the Ubuntu desktop. I can still see my cursor but that's it.
This started happening when I stopped using the IGP and put in a low end video card (Nvidia 310) and switched to using the proprietary drivers from the software and updates section of Ubuntu. The card had some issues so I removed it, and replaced it with a AMD 7770 I had. Again I instead the proprietary drivers for AMD but I still got the same issue. Black screen for a few seconds after log in. I decided to go back to using the IGP. I uninstalled all NVidia and AMD drivers by using "apt-get remove --purge" but the problem persisted.
I've tried uninstalling and reinstalling unity, and xserver-xorg, but the problem persists. I'm still a novice when it comes to Linux. Any help on how to fix this would be appreciated.
