First, as I said in my other mail, the only relevant package that needs to |
| 20 |
be rebuilt is xorg-server, nothing else. The drivers you add will be built |
| 21 |
afresh as well as dependencies for xorg-server. |
| 22 |
|
| 23 |
Second, xorg-x11 is *nothing*. It's just a meta package that pulls |
| 24 |
dependencies, it doesn't actually install a single file on your hard disk, |
| 25 |
and it doesn't compile anything at all. So, re-emerging it will do nothing. |

-N flag is not triggered based on time stamps. Each time a package is |
| 31 |
merged, the USE flags you used the last time you merged it are stored under |
| 32 |
/var/db/pkg. All -N does is to check if these flags that are stored match |
| 33 |
the current ones, and if not, the offending package is re-emerged. |

As long as you didn't emerge any single X package by hand, yes. But it |
| 42 |
will do nothing to help you, it will not solve your problem. And it's not |
| 43 |
related to your problem either. You'd just be wasting time. |
