system freeze on boot with proprietary nvidia drivers 185

the nvidia V173 driver works with recent updates but v185 still freeze my computer.

I have the same issue. 173 also doesn't work in my case.

I have the same problem with this card.

The problem appeared after a recent update. It, how ever, does not freeze the whole computer but simply the user interface. I'm not able to do anything locally, but I can open an ssh connection to the computer. Restarting gdm or executing chvt from the remote shell does not help. Moving /etc/X11/xorg.conf to /etc/X11/xorg.conf.foo seemed to fix the issue after a reboot, by defaulting to another driver.

After last update I don't have this issue. Works great.

lucky you.Mine got worse after last update .not it freezes like every 10 sec...I cant even find anything in logs.

Version 173 works fine, but a little bit slow. Version 185 was really fast, but it freezes Ubuntu during boot for me too.

It seems it has been fixed with the latest nvidia updates.

I installed Kubuntu 9.10 on my system (AMD64 / 2 x GeForce 9600) and installed the suggested nvidia-driver 185.

Got the same problem (after reboot Kubuntu-Logo and then black screen (my monitor even switches to sleeping mode)).

This problem seems to exist in the 3rd generation now:

Hope this issue will be solved soon...
