To be explicit. We would like to obtain a system log with graphics debugging enabled, after reproducing the problem. We believe the following steps should achieve that:
1) reboot, interrupt grub, and add "drm.debug=6" to the kernel command line. There is a good guide on how to do this at the URL below, see the section "Temporarily Add a Kernel Boot Parameter for Testing": https://wiki.ubuntu.com/Kernel/KernelBootParameters 2) reproduce the issue 3) hit ctrl-alt-F1 to get the text login, and then hit the power button which should trigger a clean reboot. 4) boot normally, login and attach the files /var/log/dmesg, /var/log/dmesg.0 and /var/log/syslog. Hope that makes sense. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315369 Title: Log in not available after lock screen with multi-monitor To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1315369/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
