 games not worked because this was new driver, so not all will work.

>From wiki I found:
 "no screens found"  --> ... message telling you that something

 "No devices detected" --> ...xorg.conf file doesn't contain
the correct

http://www.x.org/wiki/FAQErrorMessages/

Why I'm ask, if I have good Nvidia driver ?
  - I wanted test games from Mesa for friend from forum
     (because mesa not provide 32bit and 64bit together, closed drivers have) 
    but this is not problem, 
     I have also Intel graphic card or I can use vesa driver
http://wiki.ghostbsd.org/index.php?title=How_to_resolve_the_%22fatal_server_error:_no_screen_found%22


I have a questions
- What do with this ? Forget, or report any bugs ?
- Is this a error or deliberately disabling ?
- Exist website for nouveau driver, which hardware it support ?

[   686.445] (EE) [drm] KMS not enabled

This implies that you don't have the nouveau kernel module loaded (or
you've
loaded it with modeset=0 which effectively disables it).

Perhaps if you provide a dmesg, it will become apparent why nouveau didn't
load. Can't really tell that from the xorg log... it's just obvious that
nouveau isn't loaded.

This is true, I don't see from lsmod command,
video have 0 , in intel was driver i915.

In next day I will try save lsmod output, 
from dmesg I have only ACPI errors, nothing more from :
     dmesg |  grep -i 'error\|warning\|fail|\segfault'

To be clear, what I'm looking for is the output of dmesg. Not the output of
"dmesg | grep something".

So dmesg added, you can watch all.

There isn't a single mention of nouveau. I don't know why nouveau's
not being
loaded, but there's not even an attempt of it. Please file a bug with your
distro.

BTW, I might note that vesa is being loaded... perhaps that's upsetting
things,
although I'm not sure if that would do it.

I will cast these distribution and look for error.
I will change linux distribution.
So you can close the topic.
  See you later!
