Subject: i915/DRM bug

I can't run properly the X client(xorg as well as modular-xorg

Here's an excerpt of interesting lines of Xorg.0.log
No one outside could help me. I am new with BSD systems, and wasn't neither a power user before.

I think I had a similar problem w/ an i915-based system. There were several things buggy
at the time:

- using a PS2 keyboard caused very slow Xorg startup => installed a USB keyboard
- DRM was failing => disabled DRI/acceleration in /etc/X11/xorg.conf
- PCI bus probed incorrectly => make explicit in /etc/X11/xorg.conf

I find creating a xorg.conf.new file using 'Xorg -configure' then tweaking one thing at a time
and loading it with 'Xorg -config xorg.conf.new' helps with chasing down Xorg issues.

Good luck!

Sorry but ... How did you do this ?
How do you desactivate material accceleration ? put a diese before each
line containing "dri", and it said that my graphical card is located at
PCI:0:2:0 ... Is it an accurate pci location ?
I already use usb mouse and keyboard.

I broadcast this message for wider help.
I changed xorg.conf.new like that :
Option "NoAccel" "True"
and nothing else then a screen appeared, but only the cursor will peep out.
Then I tried xdm -config xorg.conf.new,
and xdm appear, but do not accept a connection with a regular user nor root.
My usb mouse acceleration also was wrong.
Something elses in someone's sleeve ? How to know, once and for good, if my
graphical card
has driver available for itself or not ?

What did you start ? If you started only the X server, that's normal.

What is the error message (or what happens) ?

this is something that can be fixed in xorg.conf, or with xset.

If you did see xdm's window, then your graphic card is working.
The other problems are unrelated to graphic card drivers.
