I just remembered "an excellent adventure" I had several months ago |
10 |
when setting up my HTPC (desktop Intel with onboard GPU). Do you get |
11 |
any hits when you run... |
12 |
|
13 |
grep 965 /var/log/Xorg.0.log |
14 |
|
15 |
Let me know if you do, because it would affect what I need to do. |
16 |
If you see complaints about not being able to find a driver, for a trial |
17 |
run, which doesn't make any permanent changes, try (one long line)... |
18 |
|
19 |
USE="-video_cards_i915 video_cards_i965 classic" emerge -pv --deep --changed-use @world |
20 |
|
21 |
The permanent equivalant would be changing to... |
22 |
|
23 |
VIDEO_CARDS="intel i965" |
24 |
|
25 |
...in your make.conf, adding the "classic" USE flag if you don't already |
26 |
have it, and running... |
27 |
|
28 |
emerge --deep --changed-use @world |
29 |
|
30 |
As near as I can tell... |
31 |
* the kernel uses an i915 driver |
32 |
* userspace programs (e.g. mesa) default to a userspace i915 driver. |
33 |
* but they can use the additional capacity of the newer Intel chips, |
34 |
hence the i965 userspace driver |
35 |
* result is faster acceleration |
36 |
|
37 |
You may need both "classic" and "gallium" USE flags. If you do make |
38 |
this change, can you do a video speedtest/benchmark before and after? |
