I tried to install opensuse on a Acer Aspire 2920Z Notebook. the installing procedure seemed to be done correctly. But, after rebooting the system, the display seemed to be defect. All attempts to solve the problem were in vain. On an external Monitor it is ok! Today I tried again without success: the display is damaged…
Is it possible to damage the display card by installing opensuse 11.1 in some cases?

I suppose if one went and hand editted the configuration with a bunch of really weird settings, and then deliberately let the display sit for a long time with those bad settings, its possible. But overall, IMHO its unlikely . Did you try booting to a liveCD to see if it will display ok with your notebook display?
the configuration was done by yast. with all cd’s I tried it’s still the same error…

What graphics hardware does your notebook have?
While I am a big nVidia fan, unfortunately nVidia have a very bad reputation for poor quality in their graphic card GPUs (graphic processor units) and their have been massive returns by users with notebooks with nVidia graphic hardware (due to failures).
Now It’s absolutely true: the display is defect! It’s very strange: exact to the time I installed opensuse my display crshed. And it was the first time since several years I tried this again. The display unit is an onboard INTEL GRAPHICS MEDIA ACCELERATOR (GMA) X3100.
I’m very unsure if I try opensuse with another notebook of mine… I’m only a “normal” User…

No, you can’t break your lcd because they have built-in safety measures to PREVENT going above the allowed settings.
The old “OMG I can break my display!” hasn’t been valid for years because even the CRT manufacturers prevented it by forcing limits to their display settings and simply displaying "out of range " or “out of sync”.
So, it’s only fortune…
I Think, if my notebook will be repaired, I’ll try it again.
It’s a very simple reason: I don’t like to buy Windows 7 
Thanks for all the comments and sorry for my bad english.

How could you get a correct display on the external monitor while you claim the display adapter to be defective ? There is only one GPU inside your laptop and it feeds the LCD as well as the external connector (unless it’s a special model with a low power Intel chip and a high power NVidia chipset). If it were to be broken you would get anything, neither on the internal or external screen.
I guess your LCD broke down coincidently at the same time. Maybe the backlight is broken or the invertors.
If you shine a bright light on the LCD, do you see the screen contents on the LCD ? If yes, than it’s only the CCFL tubes or invertor which is broken.
