20 (I realise your decision is made, but if this is the bug I think it is, this
21 has nothing to do with Gentoo in particular.)
23 I wonder which kernel version you use, because in 2.6.36/37 I was hit by a nasty
24 EDID parsing bug. Actually, IIRC the code for parsing EDIDs was updated to
25 understand more features or something, and that triggered errors that didn't
26 come up before because those parts of the response from the monitor were simply
27 ignored until then (or something like that). This lead to my own monitor not
28 responding for over a minute at a time (sometimes going blank in between) and
29 other people complained that it left theirs permanently blank.
31 I think this is the original bug:
35 which contains a workaround (with patch):
37 "The drm EDID checker is pretty strict about what EDIDs it will accept. Try
38 this patch and add drm.edid_strict=0 to your kernel command line."
40 For me, upgrading to 2.6.38 helped, I don't see the problem anymore (though
41 other people report otherwise).
43 *If* this is the bug, it makes me wonder why you don't see it under Ubuntu.
45 Good luck with Ubuntu!
