Hello,

I've a (small) problem with my brand new thinkpad X31 (type 2672-C8G), and
a small question about powersave mode.
First, let me introduce myself... I'm using SuSE 9.1 (KDE3.3) without any 
problem, wifi & wep included. The screen resolution is 1024x768. 

If I connect a LCD projector, the image of the screen projected on the wall is 
only a region of the total screen, and the image scrolls when I move the 
mouse (just like a virtual desktop). It seems that the LCD projector doesn't 
understand that the screen resolution is 1024x768 and uses the default 
resolution of 640x480 (or 800x600, I don't know)... It is not very 
comfortable for making presentations...
At each startup of KDE 3.3, I get the following message :
-------------------- [ snip ] ------------------------
Your monitor didn't report it's X- and Y-size, this might cause display 
problems like unreadable fonts. Do you want to configure your monitor 
geometry manually ?
-------------------- [ snip ] ------------------------
(I had this message with KDE 3.2 too).

I think this would maybe fix the LCD projector problem.
Under window$ XP Pro, the screen is correctly (totally) projected on the wall 
thus it's not a lcd projector problem.

I wrote to IBM technical Support to ask the exact X- and Y-sizes of the screen 
but got no answer (they say that they can't get this information !!!). I know 
that the screen is 12" but I want to know exactly its width and its height, 
in millimeters. Does someone has these lengths in its version of Linux (you 
can get them in SaX2, screen properties, expert tab) ??


Another question... I have the powersaved daemon running and I can activate 
the standby mode and the suspend mode. But what's exactly the difference 
between those two modes ???
And what can I do to get the computer off this sleeping mode ? Pressing the 
"poweron" button at the top of the keyboard, is it correct ?? (remember that 
I've a dual boot SuSE-XP Pro)


How can I do to get the Thinkpad automatically going to suspend mode when I 
close the LCD ?



Thank you very much for your help !!
