Hi,
for the same laptop for which I just posted a full dmesg about the
battery problem, which reports this video card:
vga1 at pci1 dev 0 function 0 "NVIDIA GeForce 8400M GS" rev 0xa1
I get a super-slow X11. Dragging an xterm may take half a second, up to
the point where X11 looses track of the mouse move events. Scrolling
XTerm is unusably slwo too.
Using a larger editor like Emacs or Firefox... even worse. It looks
totally unacelercated.
Should the 8400 work? IN the Xorg log I see this:
[ 5902.005] (II) VESA: driver for VESA chipsets: vesa

so the "nv" driver loaded.. but then further below:

I suppose the "reverting to software rendering" is the final error and
clue to the problem: no kind of acceleration at all.
