I have installed Suse 11.4 on my new laptop, an Acer Aspire 7551G.
According to Acer's product description the computer has a WSXGA Display
with 1600x900 pixels. My X runs well, but I have the impression that it
uses a smaller resolution than 1600x900.

What size is that screen?

The size of my screen is 17.3".

So I have two questions:

1. How can I determine the resolution used by my X?

1-Load in a web browser
http://fm.no-ip.com/Auth/dpi-screen-window.html and/or
2-Open KInfoCenter -> Xserver and/or
3-'xdpyinfo | grep dime'

2. In case it is lower, how can I force X to use 1600x900 px?

Really hard to answer that without knowing the output of
'lspci | grep vga' and/or output from 'hwinfo --gfxcard'.

"lspci | grep vga" produces no result, but "lspci | grep VGA" shows this line:
02:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour \
[AMD Radeon HD 6470M]

And here follows the response of "hwinfo --gfxcard"
