When i close the xterm window powertop is still running and the cpu-usage is increased. I just checked it again and it is reproducable. I also checked it with the gnome and kde terminal emulators, but there is no problem. Maybe it's a problem with xterm? Did you use xterm? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I start a two xterm instances: one running su and then powertop, one with top -p `pidof powertop`. Once I close the xterm with powertop it dies. What does $ strace -p `pidof powertop` say at the moment you're killing its xterm? For reference this is how it looks on my system: write(3, "1\n", 2) = 2 close(3) = 0 munmap(0x7fd5601c6000, 4096) = 0 select(1, [0], NULL, NULL, {15, 0}) = ?

Before I dig deeper: Does this only happen with powertop? Or does this also apply for other ncurses applications (e.g. iptraf, mc, htop)? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Then I used "su" and there was the problem again. Then I started xterm as root, nothing happened. Seems only to happen if I use "su". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But since - powertop is a developer tool and - can easily be terminated with 'q' this is neither urgent nor severe. This is something that should be handled upstream. We package powertop completely without patches. Ingo, please send a mail to the powertop mailing list: http://www.bughost.org/mailman/listinfo/power This needs to be discussed there if it is powertop which has to recognize that is was detached from terminal. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
