This bug was fixed in the package ubuntu-drivers-common - 1:0.4.17.2 --------------- ubuntu-drivers-common (1:0.4.17.2) xenial-proposed; urgency=medium
[ Alberto Milone ] * gpu-manager.c: - Fix memory leak in get_alternatives(). Make sure to always free alternatives->current_core and alternatives->current_egl. - Partially drop the drm code, and get information about connectors from sysf. This fixes a long standing performance issue (LP: #1586933). - Disable persistence mode before powering down the dGPU. If persistence mode is not disabled, gpu-manager will not be able to unload the nvidia module (LP: #1619306). - Make sure to load and unload nvidia-drm. This fixes a problem that prevents the dGPU from being powered off in hybrid systems with recent nvidia drivers (LP: #1619306). [ Ying-Chun Liu (PaulLiu) ] * Quirks/quirkinfo.py: - Catch and ignore UnicodeDecodeErrors in dmi info, as some machines may report board_name as ffffffffffff0a to mean empty, and this causes an error in python 3 (LP: #1320868). -- Alberto Milone <alberto.mil...@canonical.com> Mon, 06 Jun 2016 12:49:19 +0200 ** Changed in: ubuntu-drivers-common (Ubuntu Xenial) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1320868 Title: "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte" when removing nvidia-current package Status in ubuntu-drivers-common package in Ubuntu: Fix Released Status in ubuntu-drivers-common source package in Xenial: Fix Released Bug description: $sudo apt-get remove nvidia-current Reading package lists...
