That's good news! I was beginning to think nobody uses ATI graphics cards
on FreeBSD. :)
I currently can't recall the card manufacturer but the chip is RV710.

That's what I'm thinking about next if this can't be figured out..

I also use the monitors (Benq G2110w) with my macbook, a raspi and had
them on two PCs of friends.
Never had a problem with them and they worked fine under Linux on the same
box.

> Try same card in Linux/Windows (card is bad)
I'm trying to adopt my dual head setup from a previous ArchLinux
installation, so I think I can rule out 'bad card'.

It feels like bad driver / bad timing. The driver on Linux was much more
recent and using KMS but i have the card for quite some time and also had
this setup before KMS was introduced, which makes this problem quite
unexpected and weird.

DRI enabled and it takes down the SSH connections with it.

I attached what is left from gdb's output to the mail. Sadly I don't have
a chance to input bt before it goes down..

Comparing your output to the one i get from gdb it looks like the next
line would be
[165240.091] Mode 1680x1050 - 2240 1089 6

I'm also intrigued by the "failed to set mtrr: Invalid argument" not sure
what to make of it.


kind regards,

Henry
