I have a desktop with an integrated Radeon HD 4200 (RS880), AMD Phenom II

Both are on linux 3.0.4. Both are running gnome 3 in fallback mode. Both
have identical 1920x1080 monitors connected through HDMI ports (The
laptop's
LVDS is disabled).
Presumably the desktop is a stronger system with a faster CPU and
comparable
GPU (don't know much about the differences).
When I drag a window via the title bar on the laptop, everything is
smooth;
the window stays with the mouse cursor.
When I drag a window via the title bar on the desktop, it's sluggish; the
window lags behind the cursor.
Is it likely that something is configured incorrectly, or is there
something
implemented in the intel driver that is missing from radeon?
You might be running is sw mode if you do not have the radeon
microcode packages installed. Check your dmesg output and xorg log.

Thanks Alex. I have listed the firmwares I have installed. I do not see
anything explicitly for RS880, but I do see R600. There is a line in dmesg
indicating the RS780 microcode is loaded. Is this the wrong one? This is my
gpu:
It uses RS780*.bin and R600_rlc.bin. Note that you need to include
the ucode in your initrd if you are using one with the radeon kernel
module or build it into your kernel if you built radeon into your
kernel. Check your dmesg output and Xorg log to make sure the ucode
was available when the module loaded and that acceleration is actually
enabled.
Alex
The firmware is included in my initrd. I don't see any dmesg stating that it's
missing at any point. In xorg log:
RADEON(0): Acceleration enabled
