[Touch-packages] [Bug 1535714] Re: Xorg freeze
using std wily kernel "4.2.0-25-generic" my system will freeze over night. Happened 2 nights in a row. Leave the laptop plugged in and turned on, in the morning system is unresponsive. capslock light doesn't change. Cannot be pinged or ssh'ed into across network (wifi) When booting usual spach screen doesn't appear. Need to gues it's at encryption dialog entry, and type passwords to boot. so have removed "quiet splash" boot options. Initial bug report above was done while ssh'ed in, as keyboard not working, screen blank. Seemed like a video card driver issue as i was unable to get the screen to appear after attempting to restart lightdm service. have installed and have been running "4.4.0-997-generic" from ubuntu mainline intel driver kernel. (linux-image-4.4.0-997-generic_4.4.0-997.201601242100_amd64.deb) (after 4.2 kernel) Has been stable and wakes from suspend mode happily. Will continue to report back if chagnes in behaviour. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1535714 Title: Xorg freeze Status in xorg package in Ubuntu: Incomplete Bug description: randomly system will freeze.
