Default [195.36.08][GT 330M] 3D performance / TTY switching / monitor detection - all broken

Hello everyone,

I just acquired a new laptop, a Sony Vaio CW (VPCCW27FX). Unfortunately, 3D performance suffers in a very unusual manner.

Playing games will be very jerky and framerate can juggle from 20 fps to 120 fps unpredictably. Opening the nvidia control panel on a cold boot freezes the computer for 10 seconds and setting the PixmapCacheRoundSizeKB option will cause the entire system freeze for another 2 or 3 seconds.

Monitor detection is also broken. I'm using a downloaded EDID file from another user since the nvidia driver cannot detect the laptop screen.

And last, I can't use any tty once I have entered X because the main screen simply goes blank.

Please look into this! My laptop is pretty embarrassing to show off with all these problems.

Some interesting new system information

Default Re: [195.36.08][GT 330M] TTY switching / laptop monitor detection - bro

Ok, I uploaded the bug report.

For some reason after rebooting into different kernels and back, I no longer suffer from the strange system freezes and poor performance - but I still can't view any of my tty's after entering X.

In fact, all the problems I have remaining are what's in an existing thread - so this one can be closed unless anyone is curious.

I haven't seen any of the performance issues you mention, but I can definitely acknowledge the issues with monitor detection and TTY switching.

In addition, the TTY issue also causes Sleep/Hibernate to break.

I'm currently forced to use an EDID file in order for my display to work, and attaching an external monitor does not get detected by nvidia-control.
