[updated]
hello,
running @ qt application on raspberry pi 2. after 5 6 hours, 1 of following symptoms occurs.
1. screen goes blank second , following login form appears. if try enter credentials, brings me same login screen. after displaying login screen amount of time screen goes blank , doesn't recover. have reboot system.
2. on occasions, system reboots after displaying blank screen time.
i'm continuously pinging pi pc , when screen blanks out, pi becomes unreachable.
here setup(borrowed https://narcisocerezo.wordpress.com/201 ... operation/)
raspberry pi 2 running qt application

have disabled swap using
$ sudo update-rc.d -f dphys-swapfile remove
$ sudo swapoff /var/swap
$ sudo rm /var/swap
following settings may not relevant issues im posting them anyway sake of completeness.
edit /etc/cron.hourly/fake-hwclock , put exit 0 command @ beginning.
modify /etc/cron.daily/logrotate, adding –state /var/log/logrotate.state command line, ends like: #!/bin/sh
test -x /usr/sbin/logrotate || exit 0
/usr/sbin/logrotate --state /var/log/logrotate.state /etc/logrotate.conf
disable man-db indexing , fake-hw clock.
there several posts lightdm not being able run on read file system(i have followed general advice mount /var/lib/lightdm tmpfs problem still occurs). believe display blanking out related stumps me why issue happens after @ least 5 hrs of time.
far have been unable @ logs see causing error because mounted /var/log on tmpfs. have since redirected logs usb drive. waiting failure occur. post logs have them.
if have seen issue before, please point me in right direction.
