So, this is going to be a very elementary question, but it's honestly because |
| 6 |
I don't know. |
| 7 |
|
| 8 |
I have major problems with Firefox (and even Eclipse) acting very sluggishly. |
| 9 |
It's understandably annoying, but after using Windows for ten years, I've |
| 10 |
learned to just swallow a lot of garbage and forget about it. However, now |
| 11 |
that there's (possibly) a way to fix all this... |
| 12 |
|
| 13 |
I don't know about USE flags. I think I get that they're special compile-time |
| 14 |
preprocessor macros to enable/disable certain things, but I don't know how to |
| 15 |
use them, as in change them. |
| 16 |
|
| 17 |
If my apps all are compiled with debug extensions... that would explain why |
| 18 |
Gentoo is working (speed-wise) like Kubuntu and other Debian-based distros |
| 19 |
did. |

Well, I tried this: |

This part I'm worried about, but am not trying to fix right now. Any |
| 36 |
suggestions, though OT, would be nice. |

I see here that I've got it compiled with the debug pointers (which I'm told |
| 46 |
slow things down) and it has no KDE/Qt support, either. This... could be a |
| 47 |
problem. |
| 48 |
|
| 49 |
First: |
| 50 |
|
| 51 |
I'd like to know where I can change the USE flags globally, such that all new |
| 52 |
activity will have no debug support, which I don't need. I'd also like to |
| 53 |
add KDE/Qt functionality, if that's possible on the global level as well. I |
| 54 |
know this is probably something I should have caught when I installed, but |
| 55 |
that was a while ago, and I didn't know what a USE flag was, so I left it at |
| 56 |
the default settings, not wanting to incur the Wrath of the Malconfigured OS. |
| 57 |
|
| 58 |
Second: |
| 59 |
|
| 60 |
How can I specifically re-build a package with changed USE flags? In other |
| 61 |
words, I'd like to rebuild a few things I use often and am having speed |
| 62 |
issues with, but not the whole system (just yet - I'll want a distcc network |
| 63 |
up before I attempt the whole system all at once, esp. on this little IBM |
| 64 |
X40...) |
| 65 |
|
| 66 |
Thanks for your time! Hope I'm not too annoying! And if there's any part of |
| 67 |
my Netiquette that isn't correct, tell me. I've only been an active mailing |
| 68 |
list user for about a year and a half now, so I'm still learning! |
