GT220 & Xorg delay at startup
Using latest drivers 270.41.06 (and previous ones from 270.x) the time it takes to startup Xorg 1.10 (and previous versions back to 1.7) is almost 7 full seconds (with no disk activity). This does not happen with other nvidia cards, as I tested it with my laptop which has a Geforce Go 7400 and Xorg (same driver and xorg versions) starts up in just 1 second.

Xorg.log produces no errors at all and it just shows a delay of 5 seconds in the point where the nvidia driver probes and initializes the GPU. This same point, in my laptop takes atmost 0.5 seconds only. I have tried almost all of the nvidia driver options in X Config and none seem to mitigate the delay.

Steps to reproduce:

1. First remove the nvidia kernel module

$ rmmod nvidia
2. Then start Xorg

$ Xorg -pogo

System details
OS: Arch Linux x64 2.6.38-ARCH, Xorg v1.10, Nvidia drivers v270.41.06
CPU: Core 2 duo E6400
GPU: Nvidia GT220
MB: Asus P5Q

How much time does your system takes to startup xorg (Use Xorg -pogo to do the benchmark)? Is this problem known and is there a solution?

Re: GT220 & Xorg delay at startup
We can confirm this with multiple setups using G210/ION2
OS is amd64 Natty, kernel 2.6.38-8
when looking at bootchart it takes 8-10s from Xorg start until the wm starts

I will try to get the data you are requesting later for these.

For my 32bit natty installation (E7400, G210, 4GB DDR3 mem) its:
real 0m3.057s

I will reinstall this weekend with 64bit and provide the time from there.

All times are GMT -5. The time now is 04:27 AM.
