The error that you see in the log was caused by this code: if (is_disabled_in_cmdline()) { fprintf(log_handle, "Disabled by kernel parameter \"%s\"\n", KERN_PARAM); goto end; }
That simply parses /proc/cmdline. A few more things to try: 1) Maybe what you see is an old log. Try with: sudo rm /var/log/gpu-manager.log and reboot See if you can still see the same gpu-manager.log (with the same error about the nogpumanager parameter) 2) Try starting the upstart job: sudo rm /var/log/gpu-manager.log sudo start gpu-manager And see what /var/log/gpu-manager.log says 3) If 1) and 2) fail, try this: sudo rm /var/log/gpu-manager.log sudo gpu-manager --log /var/log/gpu-manager.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
