My current xorg.conf
This is my current xorg.conf file, with the Option AccelMethod added manually.
I forgot to mention that adding this line to xorg.conf made huge difference. The system now behaves as expected. The 500ms delay completely dissapeared. SNA has been enabled by default in upcoming Mageia 4 since August CC:

RPM Packages Will the upgrade from Mageia 3 to Mageia 4 also enable SNA? Yes I have just installed Mageia 4 on a clean system, and there is no option AccesMethod = SNA in xorg.conf. So it looks as if SNA is not enabled by default. It is enabled by default in the driver build, so there is no need for that line in xorg.conf CC:

RESOLVED |
Description of problem: After installing Mageia 3, the video performance is relatively poor on my Dell Latitude E5420 with a Core i5 processor and Intel HD 3000 graphics card. The most annoying behaviour is a slow response of applications to GUI user input. For example clicking on another tab in firefox to switch to it would have a delay close to 500 ms until the application started to responded to the click. Other applications behave similarly. The strage thing is that it does not look like slow rendering (I know how software rendering looks like, or otherwise slow rendering), but rather a general poor response to user input (I'm speaking of course only about GUI applications). Solution: I recently found a solution which worked very well. I added following line to the "Device" section in /etc/X11/xorg.conf: Option "AccelMethod" "sna" I think it would be nice if the installer or config tool would add this option to xorg.conf automatically when necessary. It applies to Sandy Bridge, and probably also newer generations of Intel Graphics. Reproducible: Steps to Reproduce:
