Bug#910631: lightdm: first login hangs waiting for user-generated entropy
Package: lightdm Version: 1.26.0-3 Severity: grave Justification: renders package unusable Dear Maintainer, On my buster/sid system, LightDM hangs indefinitely on first login until entropy is generated via mouse or keyboard input. The login process seems to be delayed by the kernel itself, until the following lines appear in journalctl: kernel: random: crng init done kernel: random: 7 urandom warning(s) missed due to ratelimiting Installing the haveged package fixes the issue, as mentioned in the following thread: https://unix.stackexchange.com/questions/442698/when-i-log-in-it-hangs-until- crng-init-done This issue also seems related to bug #897572 -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-2-amd64 (SMP w/2 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lightdm depends on: ii adduser3.118 ii dbus 1.12.10-1 ii debconf [debconf-2.0] 1.5.69 ii libaudit1 1:2.8.4-2 ii libc6 2.27-6 ii libgcrypt201.8.3-1 ii libglib2.0-0 2.58.1-2 ii libpam-systemd 239-10 ii libpam0g 1.1.8-3.8 ii libxcb11.13-3 ii libxdmcp6 1:1.1.2-3 ii lightdm-gtk-greeter [lightdm-greeter] 2.0.5-1 ii lsb-base 9.20170808 Versions of packages lightdm recommends: ii xserver-xorg 1:7.7+19 Versions of packages lightdm suggests: pn accountsservice ii upower 0.99.8-2 pn xserver-xephyr -- Configuration Files: /etc/lightdm/lightdm.conf changed [not included] -- debconf information: * shared/default-x-display-manager: lightdm lightdm/daemon_name: /usr/sbin/lightdm

Hi, here is the gdb session with libc6 debug symbols.
Starting program: /usr/bin/vlc -vvv -I dummy ~/dl/freebox-tv.m3u

Do you need set solib-search-path or set sysroot?

Bug#710190: vlc: Segfault when opening a playlist containing rtsp urls
Ok, so I updated libproxy0 to the latest version (0.3.1-6/stable,testing,unstable) and the bug is gone ! Currently the vlc-nox package depends on libproxy0 = 0.2.3 Maybe should it be updated to depend on libproxy0 = 0.3.1 ? Le 30/05/2013 17:20, Reinhard Tartler a écrit : On Thu, May 30, 2013 at 5:16 PM, Rémi Denis-Courmont r...@remlab.net wrote: I am not familiar with libproxy internals. Due to the swarm of crash reports, I have made VLC 2.1 execute /usr/bin/proxy from proxy-tools in a separate process instead of calling libproxy directly. (This also weakens the run-time dependency on libproxy.) At least, VLC will not crash anymore. Given the maturity consideration of libproxy, this seems reasonable. Thanks for this! Also, reading bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604934 makes me feel sad and wonder, if there was some way to disable the usage of libproxy in vlc altogether? For VLC 2.0, either `./configure --disable-libproxy' or build-time conflict with libproxy-dev ought to do. Then the plain old $http_proxy will be used. That makes sense to me. Benjamin, I suggest to do so in both Debian and Ubuntu. What do you think? -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
