Grant - Here's where I got to today: |
32 |
|
33 |
1) My machines use the ATI 9100 IGP chipset. No 3D accel. The machines |
34 |
have both composite video and S-Video outputs. |
35 |
|
36 |
2) Back under 2.6.16 I used ati-drivers-8.14.x. I had to patch the |
37 |
drivers by hand. That was painful but well documented on one of the |
38 |
online forums. |
39 |
|
40 |
3) The 8.14 driver is no longer in portage and apparently doesn't work |
41 |
with the 2.6.17 kernels. |
42 |
|
43 |
4) I got 8.28.8 working today using the following extra line in the |
44 |
aticonfig-Device[0] section created by aticonfig: |
45 |
|
46 |
Option "ForceMonitors" "nocrt1,nocrt2,tv" |
47 |
|
48 |
5) What I found was that during the boot I get text on both the |
49 |
composite video and S-Video outputs. However, when X starts the |
50 |
graphic output is only on the S-Video output. This is different than |
51 |
the older driver where X was available on both. |
52 |
|
53 |
6) All of that said I've now got both Pundit-R's working. However the |
54 |
video quality is far worse than the previous driver. It appears that |
55 |
I'm getting just a few frames of video every second. Video from MythTV |
56 |
is very jerky and seems to 'tear' a bit. |
57 |
|
58 |
7) Note that this doesn't seem to be nearly as bad when I configure |
59 |
the machines to use the CRT output. I'm going to investigatge buying |
60 |
some sort of VGA->S-Video or Composite video converter. That may work |
61 |
better and not require all this crazy work. |
62 |
|
63 |
All in all, very disappointing. I understand the Gentoo devs had |
64 |
their hands tied on a lot of this stuff but it's disappointing to have |
65 |
working drivers get dropped from portage or the driver developers at |
66 |
ATI not continue to move features forward. Or maybe it's still me and |
67 |
my lack of real configuration knowledge. |
68 |
|
69 |
Hope this helps, |
70 |
