syslog messages standy and resume - working
Hello,
I use Kubuntu 14.04.x together with a nvidia graphics card NVC1 (GF108) GT 430
passive and driver nouveau.
Standby and resume works with the nouveau driver, but hibernate and resume
don't.
There is a black screen after resume, then the monitor goes off (no signal) and
no keyboard input is possible => Only a hard reset helps.
*** Package versions
Kubuntu 14.04.1 64bit
nouveau version 1.0.11-1-ubuntu2~trusty
Mesa 10.3.2, Xserver 1.16.0 (Utopic (14.10) Xstack)
kernel 3.16.x (also tested kernel 3.18.5 and 3.19rc7)
I have attached the following logs; with kernel parameter nouveau.debug=trace
--- syslog and xorg.log for the working standby
syslog_standby_resume.txt
standby_resume_Xorg.0.log.old_working.txt
--- syslog and xorg.log for the (hibernate) and resume problem
syslog_hibernate_resume_NOT_working.txt
hibernate_resume_Xorg.0.log.old_NOT_working.txt
--- lspci.txt
There is a crash at the xserver;
