Ubuntu stuck after log in

Question

I'm using Ubuntu 14.04 on Vmware.

After I put my password to log in, It just stuck like the screenshot below.

Any suggestions? or something to reference?

Solution

If you can access the console, then you have a problem with Xorg or your window manager (lightdm? gdm? kdm?...). Login, then from the console stop the graphic session,

  sudo service lightdm stop

(please correct for your WM). Now you have to troubleshoot the local problem. First, make a full system upgrade and reboot. Again from the console, start the WM and see which, if any, errors are reported.

  sudo service lightdm start

Alternatively look up the /var/log/Xorg.0.log* file, and see whether any error is reported. You can take it from here.

ram available to guest (the ubuntu vm)? graphics card? (again to the vm) --can the host OS support these settings ?

@linuxdev2013 vm settings might not a problem. I used it until yesterday, I think some updates cause this problem.

No screenshot below. Can you access one of the consoles? Host key + F1, the Host key is normally the right control key.

@MariusMatutiae Yes, I can access the console.

I found an error in /var/log/Xorg.0.log file. "(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)". Cuda toolkit, I installed caused a problem. I uninstalled it and can log in successfully.

@enc What exactly did you uninstall and how? can you write an answer? I have same exact problem on 16.04.3 LTS.

@Shayan Removing cuda toolkit helped as I mentioned above. this may help.

which nvcc returns nothing so I guess I don't have it installed!
