I'm not sure. I know on my previous install, it spent many seconds |
| 8 |
sitting at the console, printing something about USB hubs losing power |
| 9 |
or getting reinitialized and then switching into X. From a totally |
| 10 |
naive standpoint, I could think of 3 areas to look into: |
| 11 |
|
| 12 |
- how long do common laptop bios configs take to hand off to the OS |
| 13 |
when waking up and if any fixups or BIOS configuration tips are |
| 14 |
possible to make it faster |
| 15 |
- how long does the kernel take to wake up the subsystems and |
| 16 |
processes - there is probably benchmarking data on this somewhere or |
| 17 |
it's possible to easily get it from kernel debug logs. Make a list of |
| 18 |
modules/options to avoid due to long wake times. Identify problematic |
| 19 |
modules which need work to speed up (USB?) or whose wake-up can be |
| 20 |
backgrounded while the kernel hands off to userland (one would need to |
| 21 |
be or know a kernel hacker to do this). |
| 22 |
- how long does X take to come up once it has control. e.g. kernel |
| 23 |
modesetting could possibly help here, but in general this would entail |
| 24 |
benchmarking what exactly X is doing. |
| 25 |
- how long does the display manager take to bring the screen or the |
| 26 |
unlock dialog back up. This gets into multiple possibilities but |
| 27 |
checking the default installs of Gnome and KDE for obvious delays |
| 28 |
could be worth it. |

I'd start with Donnie's suggestion. |
