I have a desktop with an integrated Radeon HD 4200 (RS880), AMD Phenom II X4
965. Driver v6.14.2
I also have a laptop with an i915, Intel Core i3 M370. Driver v2.16.0
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?
