Awesome, the simple change dmesg | grep, to grep syslog saves me about 1 second in gpu-manager, and possibly 2 in total boot time (from 7 seconds to 5). If the changes are proportional for a rotational HDD this will be a major speed improvement there..
I was thinking about using the journalctl instead, but that didn't work - seems to take longer. Find seems to be the other big time culprit: - "find /lib/modules/$(uname -r) -name '%s*.ko' -print", + "find /lib/modules/$(uname -r)/updates/dkms -name '%s*.ko' -print", Do we always know that the modules will be under updates/dkms or could they be elsewhere? With that, it's far under 500ms for me (with strace on). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1307069 Title: gpu-manager causing long startup delays Status in ubuntu-drivers-common package in Ubuntu: In Progress Bug description: I have installing ubuntu 14.04 beta2 and i have update it to latest.
