Even that is strange. I just tried. Processus that are not mine are not shown anymore by ps, but even some of mine disappeared! (mostly urxvt ones) See this example (the [] in the grep command are here to avoid to find the grep command itself): $ ps axfu | grep 321[6]1 vdanjean 32161 0.0 0.0 104796 2244 ? S févr.24 0:01 /usr/bin/urxvt $ sudo mount -o remount,hidepid=1 /proc $ ps axfu | grep 321[6]1 $ sudo mount -o remount,hidepid=0 /proc $ ps axfu | grep 321[6]1 vdanjean 32161 0.0 0.0 104796 2244 ? S févr.24 0:01 /usr/bin/urxvt $ logname vdanjean $ sudo mount -o remount,hidepid=2 /proc $ ps axfu | grep 321[6]1 $ sudo ps axfu | grep 321[6]1 vdanjean 32161 0.0 0.0 104796 2244 ?
