I tried to add a raster layer to my QGiS dufour(memory size of the image was 52 MB) and the desktop freezed. It is not just QGIS,I have also tried to open this image via image viewer and it has also caused desktop to freeze.

Any ideas how to fix this?

Thanks in advance!!!

If it was RAM,then it would be a problem for windows too,but windows is working fine,so i think it's not RAM. –  Luka Dec 9 '13 at 13:04

I have the same problem with Ubuntu 13.10. The whole system freezes for anything from about 15 - 60 seconds after loading a large image in Firefox or using Google maps in satellite view. While it is frozen you cannot move the mouse or do anything. When it comes out of the freeze everything then works as normal... until the next freeze up! Very annoying. This problem started after upgrading to Ubuntu 13.10.

I found that if, when you boot up the computer, you select in GRUB the linux kernel which was used in ubuntu 13.04 ( 3.8.0-34-generic ) this problem does not occur.

Thanks for your response,but i figured out that ubuntu has a problem with opening images with jp2 extension. The image i tried to edit/open was big,so i assumed that ubuntu just won't open big images(which was stupid thinking). I converted that file into some other image format and it works perfectly fine. –  Luka Feb 10 at 21:59

Change your viewer from EOG to GPICVIEW .

I had the same problem. Large images (3000x3000, roughly 3-5M on a RAM set of over a gig), causing total desktop lockup (requiring shutdown and restart). I thought RAM was going bad so I did memtest and no. I thought my drive might be bad so I did Disk Utility check and no.

I hope this helps.
