Well, I suppose, but this is all automatic. To my knowledge, I haven't
specified it anywhere. One thing bothers me a little --- this is an AGP card,
why is the bus id a PCI specification? Is that part normal?
There is a series of lines in the XFree86.0.log file which appears to show the
autodetection process:
"""
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (Unknown error 999)
drmOpenDevice: open result is -1, (Unknown error 999)
drmOpenDevice: Open failed
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (Unknown error 999)
drmOpenDevice: open result is -1, (Unknown error 999)
drmOpenDevice: Open failed
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 5, (OK)
drmOpenDevice: minor is 1
drmOpenDevice: node name is /dev/dri/card1
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
"""
(I've included some failures for context -- there's a dozen or so failed
combinations, and only the one device at /dev/dri/card0 found. One
odd thing -- what is the difference between the first 3 attempts? They
all look like they are using the same parameters to reach /dev/dri/card0,
but only the last one fails. Is that normal? Why "Unknown error"
instead of "No such device"?)
> Did you check it against lspci?
I have done so now. ;-)
Here's the relevant lines:
"""
0000:01:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 9200] (rev 01)
0000:01:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200] (Secondary) (rev 01)
"""
I'm a little uncertain about how to read the bus ids here, but they look plausible. Maybe
it should read PCI:1:0:1 or PCI:0:1:0? Even if I want to change this, though, where do I
put the information? Is there a line in XF86Config-4 for this? I suppose I can try to
set these with "dpkg-reconfigure xserver-xfree86" -- I'm pretty sure there is an option to
specify the bus. But what should I tell it, if this isn't right?
> Or maybe just the syntax of that line wrong?
Um, which line? Again, I don't know where this would be specified. A syntax error
sounds promising, but I don't know where to look for it. ISTM, whatever syntax is
being used is being created by the driver software?
I'm willing to go to a new driver or whatever if that's required, but this looks like a
very minor problem --- it seems like there *ought* to be something I can specify
somewhere to make this behave.
I'm also looking at the Gatos project and the Debugging DRI page:
http://gatos.sourceforge.net/dri-debug.php
but it appears to me that this would involve compiling and installing new drivers,
which means getting kernel-headers and so on. I'd like to avoid that if there's a
simple configuration solution (which I'd likely have to solve anyway, even for new
drivers).
