Sadly, I can not contribute to testing, since terminals, and so bash, are how I do most of my actions on my system, and having it that slow makes the system almost unusable. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

very slow Xorg and/or bash
Hello. Since few days, say 4 or 5, my netbook is *really* slow when a terminal starts. After taking a look with top, it seems that it's bash itself which is the problem: it makes the terminal freezing for at least 15s on login, and almost the same when using auto-completion. There is also xorg, which uses constantly at least 10% of the CPU, if I trust top ( at least, means that it is the minimal value ). I have no idea about how to find the origin of the problem, this is why I am not giving any real hint or suppositions. I do not remember having updated anything particular ( but no doubt that I did, otherwise I could not have such kind of constant slowness ). I am using a testing/unstable/experimental debian, no DE. wheezy's packages have priority 900, unstable ones only 200, except for compilers ( Package: clang* gcc* g++* cpp* libgfortran* ) Running services are currently: # service --status-all [ + ] acpi-fakekey [ - ] acpi-support [ + ] acpid [ ? ] alsa-utils [ ? ] binfmt-support [ - ] bootlogs [ ? ] bootmisc.sh [ ? ] checkfs.sh [ ? ] checkroot-bootclean.sh [ - ] checkroot.sh [ - ] console-setup [ - ] cups [ + ] dbus [ ? ] hdparm [ - ] hostname.sh [ ? ] hwclock.sh [ - ] kbd [ - ] keyboard-setup [ ? ] killprocs [ ? ] kmod [ - ] motd [ ? ] mountall-bootclean.sh [ ? ] mountall.sh [ ? ] mountdevsubfs.sh [ ? ] mountkernfs.sh [ ? ] mountnfs-bootclean.sh [ ? ] mountnfs.sh [ + ] mpd [ ? ] networking [ - ] procps [ ? ] rc.local [ - ] rmnologin [ - ] rsync [ ? ] sendsigs [ - ] ssh [ - ] sudo [ + ] tor [ + ] udev [ ? ] umountfs [ ? ] umountnfs.sh [ ? ] umountroot [ - ] urandom [ + ] wicd [ - ] x11-common Any idea about the problem? Or at least any idea about what to look for to have one? I suspect some bash script, but the slowness is also with root, and I did not changed anything by hand that could affect root since at least 2 weeks. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
