Hello I've encountered the same problem since the update of the following packages yesterday : tart-Date: 2015-08-04 13:02:52 Commandline: apt-get upgrade Upgrade: kde-style-breeze-qt4:amd64 (5.3.2-3, 5.3.2-4), breeze-cursor-theme:amd64 (5.3.2-3, 5.3.2-4), kwin-style-breeze:amd64 (5.3.2-3, 5.3.2-4), gir1.2-packagekitglib-1.0:amd64 (1.0.6-1, 1.0.6-1+b1), kde-style-breeze:amd64 (5.3.2-3, 5.3.2-4), breeze:amd64 (5.3.2-3, 5.3.2-4), libseccomp2:amd64 (2.2.1-2, 2.2.3-1), breeze-icon-theme:amd64 (5.3.2-3, 5.3.2-4), qml-module-qtquick-controls-styles-breeze:amd64 (5.3.2-3, 5.3.2-4), python-reportbug:amd64 (6.6.3, 6.6.4), reportbug:amd64 (6.6.3, 6.6.4) End-Date: 2015-08-04 13:03:04 Symptom: Regularly, system freezes during session opening (i.e before desktop is available, during session loading). In this case a sudo reboot must be done. When, by chance, you can reach the desktop, screen freezes as soon as a window is open (Konsole, Kvirc,...). But cursor/mouse/keyboard is still working. --> Ctrl Alt F6 to switch to a consol : a ps -eaf |grep kwin shows one or several process(es) like : kwin-x11 --crashes 1, kwin-x11 --crashes 2, ... If all Kwin process are killed, you can partially get back the control of the system, but all windows are borderless. Hope this will help. regards Cédric -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org |
