I didn't mention this before, because it's not directly relevant to
FreeBSD, but I've also had serious problems with the graphics chip in
my Inspiron 6000: I can't get it to drive a projector correctly. This
is a machine with 1920x1200 display and the following chip set (sorry
for the Linux):
01:00.0 VGA compatible controller: ATI Technologies Inc M22 [Radeon Mobility M300] (prog-if 00 [VGA])
Subsystem: Dell Unknown device 2003
Flags: bus master, fast devsel, latency 0, IRQ 11
Memory at d0000000 (32-bit, prefetchable) [size=128M]
I/O ports at de00 [size=256]
Memory at dfdf0000 (32-bit, non-prefetchable) [size=64K]
[virtual] Expansion ROM at dfd00000 [disabled] [size=128K]
Capabilities: [50] Power Management version 2
Capabilities: [58] Express Endpoint IRQ 0
Capabilities: [80] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-
Capabilities: [100] Advanced Error Reporting
The LCD display works perfectly with FreeBSD and also most versions of
Linux (some don't recognize the aspect ratio or the resolution of the
screen). But I can't get X to change the horizontal frequency, which
is set at 74.1 kHz, too high for most projectors. The driver just
ignores any attempts to set a mode line with a different frequency. I
assume this is a bug in the X driver.
FWIW, the chips with which I've had the fewest problems have been
nVidia, though all my experience with them has been in desktop class
machines.
