I try with failsafe session but cannot get output from strace in file because straced gnome-session commnads never ends. So i get empty output file. I tried strace -ttt gnome-session > out.txt and strace -ttt gnome-session -o out.txt but in each case out.txt has 0 bytes length after CTRL+C. Tried to find option for breaking tracing in man strace, but cannot find one. Darek Borkowski
