Hello
Recently I decided to install my first linux. I choose openSUSE. Installation went smooothly and everything seemed to work just fine. After few days i noticed that sometimes my screen blinks for some time. During this blinking everything is working very slow. Today when blinking started i decided to see CPU usage of specific processes and I noticed that during this strange behaviour Xorg CPU usage is about 40% or more, it seems odd to me because usually it is few %. I am wondering what is the cause of this behaviour and how can I do something about it…
I am using KDE, my graphics card is Intel GMA 4500.

You might give the kernel load option nomodeset a try and see if it helps. Basically, nomodeset is already part of the Failsafe openSUSE startup (which you can look at on how to add it in if it helps). When you boot your computer and the Grub Operating System selection menu comes up, you can just type in nomodeset and then press the enter key to see if this helps. You can later edit the file /boot/grub/menu.lst as root and add in the command (in KDE do a Alt-F2 and then enter: kdesu kwrite /boot/grub/menu.lst) OR you can run YaST / System / Boot Loader and edit the kernel load line from there. With Intel, doing a kernel update clear up to 3.0 can also be helpful, but try nomodeset first.
Ok, I added nomodeset to parameters, some graphics errors are now missing, I will work some time under those settings and see if everything works fine, only one thing bothers me. Now I can’t change my screen resolution, there is only 1024x768, and I should have 13xx something, I wonder if I can change it manually somewhere else (not in system configuration panel) or maybe I can’t when using nomodeset.

Open a terminal and type
xrandr
to display your display device name(s) and available display modes.
Create/edit a minimal xorg.conf with an editor like this for KDE:
kdesu kwrite /etc/X11/xorg.conf
For Gnome:
gnomesu gedit /etc/X11/xorg.conf
Create/adjust the monitor section like this for example:
You can see I’ve used my laptop display name LVDS. (You’ll need to use the
display name as per your xrandr output). When done, save the file, and restart
the X-server. Now your desktop should start up in your preferred display mode.
xrandr: Failed to get size of gamma for output default

default connected 1024x768+0+0 0mm x 0mm

so the display name of my device is default? If yes, then when I created xorg.conf and put
More info:
but when I run w/o nomodeset my xrandr looks like this

When not using nomodeset, it looks like the video is called LVDS1. I am certain I would attempt to upgrade your kernel to version 3.0 to see if that might be helpful. Here is a link for info on how to do that.
