Lately my boot time is becoming very slow. I suspect that it has something to do with the nvidia drivers. It is stuck in a loop for 45 minutes trying to detect GPU:
here is the tail of the boot log:
===========================================================
(2 of 2) A start job is running for Detect the available GPUs and deal with any system changes.

=====================
not sure if relevant, lspci shows nvidia 3D controller (and other things):
3D controller: NVIDIA Corporation GK208M [GeForce GT 740M] (rev a1)
again, not sure if relevent. systemctl status gpu-manager.service shows:
gpu-manager.service - Detect the available GPUs and deal with any system changes.
Loaded: loaded (/lib/systemd/system/gpu-manager.service; enabled; vendor preset: enabled)
Active: inactive (dead) since ד' 2015-11-11 00:07:08 IST; 13h ago
Main PID: 840 (code=exited, status=0/SUCCESS)
Warning: Journal has been rotated since unit was started. Log output is incomplete or unavailable.
Update: I rebooted and again it took 45 minutes. What does this mean? I understand that some process is looking for the GPU and it cannot start the desktop until it finds it or gives up, and it seems like it gives up after 45 minutes. Is there some place where a time interval for "give up" is defined?
Please help me understand whats going on and how to fix it.
