Without changing the image_size, it especially got much better when I downgraded QT 4.6 to QT 4.5 which does not work well with KDE 4.3 (seems to cause memleaks). However, image_size is already set to your recommended value (well, approximately): # cat /sys/power/image_size 951431086 My RAM size is 2 GB (however, I have intel graohics with shared mem, so some part is reserved), my swap size is a little bit more than 2 GB. I don't know what value image_size was set to when I tried first. Note that when I reported the issue first I used Debian kernel 2.6.32-1, (probably plain 2.6.32), while I'm now using Debian kernel 2.6.32-2 (according to the changelog 2.6.32.1) WM _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
