Package: gnome Version: 1:3.14+3 Severity: critical Justification: causes serious data loss
*** Scenario *** Non-classic gnome logged as a regular user and some root windows open. e.g. synaptic, nautilus-as-root, root-terminal, etc. *** Causing the problem *** Hitting the upper left corner of the screen with mouse cursor - or - clicking over Activities. *** Problem *** Screen freezes (no usual shrink) cursor moves. No reaction to clicks. *** Observation *** top, running on a <ctrl><alt><F1-6> text window shows gnome-settings-daemon busy (50%). Logs like syslog, messages, etc. get huge filled with several messages like below: <<< gnome-session[1367]: (gnome-settings-daemon:1434): dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user': Access denied. dconf will not work properly. >>> ls -l /run/user/1000/dconf/user --> -rw------- 1 root root 2 Dec 13 21:42 /run/user/1000/dconf/user !!! rebooting: ls -l /run/user/1000/dconf/user --> -rw------- 1 user user 2 Dec 13 21:54 /run/user/1000/dconf/user *** My conclusion *** For some reason the owner of the file referred above turns from user to root. >From this moment on gnome system is desperately trying to access it as user, overloading the machine, filling logs with same message, and no escape. *** My comments *** 1) As I don't know which part of software is responsible for /run/user/1000/dconf/user writing and creation I blame gnome. 2) It can be harmful to the system because when one doesn't what to do, he/she will press reset button and get corrupted files. 3) A workaround for the crash is to hit <ctrl><alt><F1-6> and <ctrl><alt><del>. 4) By now, when I need work as root, I hit <ctrl><alt><F1-6> and startx. Some say it might lead to safety problems ... Thanks for your patience, anyway, I believe solution is closer. -- System Information: Debian Release: 8.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: i386 (i686) Kernel: Linux 3.16.0-4-686-pae (SMP w/2 CPU cores) Locale: LANG=pt_BR.utf8, LC_CTYPE=pt_BR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gnome depends on: ii alacarte 3.11.91-2 ii avahi-daemon 0.6.31-5 ii bijiben 3.14.2-1+b1 ii brasero 3.11.4-1.1 ii cheese 3.14.1-2 ii cups-pk-helper 0.2.5-2+b1 ii desktop-base 8.0.2 ii evolution 3.12.9~git20141130.241663-1+b1 ii evolution-plugins 3.12.9~git20141130.241663-1+b1 ii file-roller 3.14.1-1 ii gedit 3.14.0-3 ii gedit-plugins 3.14.0-2 ii gimp 2.8.14-1+b1 ii gnome-clocks 3.14.1-1 ii gnome-color-manager 3.14.1-1 ii gnome-core 1:3.14+3 ii gnome-documents 3.14.2-1 ii gnome-games 1:3.14+3 ii gnome-getting-started-docs 3.14.1-1 ii gnome-logs 3.14.2-1 ii gnome-maps 3.14.1.2-1 ii gnome-music 3.14.1-1 ii gnome-nettool 3.8.1-1 ii gnome-orca 3.14.0-4 ii gnome-photos 3.14.2-1 ii gnome-shell-extension-weather 0~20140924.git7e28508-1 ii gnome-sound-recorder 3.14.0.1-1 ii gnome-tweak-tool 3.14.2-2 ii goobox 3.3.1-6 ii gstreamer1.0-libav 1.4.4-2 ii gstreamer1.0-plugins-ugly 1.4.4-2+b1 ii hamster-applet 2.91.3+git20120514.b9fec3e1-1 ii inkscape 0.48.5-3 ii libgtk2-perl 2:1.2492-4 ii libreoffice-calc 1:4.3.3-2+deb8u2 ii libreoffice-evolution 1:4.3.3-2+deb8u2 ii libreoffice-gnome 1:4.3.3-2+deb8u2 ii libreoffice-impress 1:4.3.3-2+deb8u2 ii libreoffice-writer 1:4.3.3-2+deb8u2 ii nautilus-sendto 3.8.2-1 ii network-manager-gnome 0.9.10.0-2 ii polari 3.14.1-1 ii rhythmbox 3.1-1 ii rhythmbox-plugin-cdrecorder 3.1-1 ii rhythmbox-plugins 3.1-1 ii rygel-playbin 0.24.2-1+b1 ii rygel-tracker 0.24.2-1+b1 ii seahorse 3.14.0-2 ii simple-scan 3.14.0-1 ii telepathy-gabble 0.18.3-1+b1 ii telepathy-rakia 0.8.0-3 ii telepathy-salut 0.8.1-4 ii totem-plugins 3.14.0-2 ii transmission-gtk 2.84-0.2 ii vinagre 3.14.1-1 ii xdg-user-dirs-gtk 0.10-1 Versions of packages gnome recommends: pn gnome-software <none> Versions of packages gnome suggests: pn iceweasel-l10n-all <none> pn xul-ext-adblock-plus <none> pn xul-ext-gnome-keyring <none> Versions of packages gnome-core depends on: ii adwaita-icon-theme 3.14.0-2 ii at-spi2-core 2.14.0-1 ii baobab 3.14.1-1 ii caribou 0.4.15-1 ii caribou-antler 0.4.15-1 ii dconf-gsettings-backend 0.22.0-1 ii dconf-tools 0.22.0-1 ii empathy 3.12.7-1 ii eog 3.14.1-1 ii evince 3.14.1-2 ii evolution-data-server 3.12.9~git20141128.5242b0-2+deb8u2 ii fonts-cantarell 0.0.16-1 ii gdm3 3.14.1-7 ii gkbd-capplet 3.6.0-1 ii glib-networking 2.42.0-2 ii gnome-backgrounds 3.14.1-1 ii gnome-bluetooth 3.14.0-2 ii gnome-calculator 3.14.1-1 ii gnome-contacts 3.14.1-1 ii gnome-control-center 1:3.14.2-3 ii gnome-dictionary 3.14.1-1 ii gnome-disk-utility 3.12.1-1+b1 ii gnome-font-viewer 3.14.0-2 ii gnome-keyring 3.14.0-1+b1 ii gnome-menus 3.13.3-6 ii gnome-online-accounts 3.14.2-1 ii gnome-online-miners 3.14.0-2 ii gnome-packagekit 3.14.0-1 ii gnome-screenshot 3.14.0-1 ii gnome-session 3.14.0-2 ii gnome-settings-daemon 3.14.2-3 ii gnome-shell 3.14.4-1~deb8u1 ii gnome-shell-extensions 3.14.2-1 ii gnome-sushi 3.12.0-2+b1 ii gnome-system-log 3.9.90-2 ii gnome-system-monitor 3.14.1-1 ii gnome-terminal 3.14.1-1+deb8u1 ii gnome-themes-standard 3.14.2.2-1 ii gnome-user-guide 3.14.1-1 ii gnome-user-share 3.14.0-2 ii gsettings-desktop-schemas 3.14.1-1 ii gstreamer1.0-plugins-base 1.4.4-2 ii gstreamer1.0-plugins-good 1.4.4-2 ii gstreamer1.0-pulseaudio 1.4.4-2 ii gtk2-engines 1:2.20.2-3 ii gucharmap 1:3.14.1-1 ii gvfs-backends 1.22.2-1 ii gvfs-bin 1.22.2-1 ii gvfs-fuse 1.22.2-1 ii iceweasel 38.4.0esr-1~deb8u1 ii libatk-adaptor 2.14.0-2 ii libcanberra-pulse 0.30-2.1 ii libcaribou-gtk-module 0.4.15-1 ii libcaribou-gtk3-module 0.4.15-1 ii libgtk-3-common 3.14.5-1+deb8u1 ii libpam-gnome-keyring 3.14.0-1+b1 ii metacity 1:3.14.3-1 ii mousetweaks 3.12.0-1 ii nautilus 3.14.1-2 ii policykit-1-gnome 0.105-2 ii pulseaudio 5.0-13 ii sound-theme-freedesktop 0.8-1 ii totem 3.14.0-2 ii tracker-gui 1.2.4-2 ii vino 3.14.0-2+b1 ii yelp 3.14.1-1 ii zenity 3.14.0-1 Versions of packages gnome-core recommends: ii anacron 2.3-23 ii network-manager-gnome 0.9.10.0-2 gnome-core suggests no packages. -- no debconf information
