Login start problem

Question

After years of no problems with my Ubuntu 12.04, today my laptop began experiencing the following problem. When I get to the login screen, it apparently freezes. Regardless, I type my password and hit Enter. Nothing happens. I wait like a minute or a minute and a half and suddenly the password shows in the box (I mean, the dots representing the password) and the machine resumes the login process and operates normally. How do I troubleshoot this problem? Your help is appreciated.

Here's some info about my machine:

My experience seems similar except my system is running UbuntuStudio on a HP Pavilion g6, Core i7, Radeon GPU....

I've tried xstart and reinstalled from a fresh dl of 12.04.4. It has worked for about one day then ends up with tty1 each time.

Answer 2

The same for me. I use Xubuntu 12.04.4 LTS x64, and I never had a problem until I upgraded the kernel to 3.2.0-61. I use a NVIDIA GTX 660 that worked perfectly with proprietary drivers (CUDA included). I am trying to downgrade the kernel, but I don't know yet if that is the final solution. Other solutions like start with nomodeset or with acpi_osi=Linux didn't work for me. I think we should wait for a new revision of the kernel.
