VGA output is wavy on a dell vostro laptop (core i5 + intel hd graĥics). I try all modelines i could, but the display is always more or less garbled with some sort of waves all over the screen. I have the same problem with another laptop and latest xf86-video-ati. Internel LVDS display work fine. I can reproduce this strange behaviour on ubuntu 10.04, and on a gentoo with latest components (xorg 1.7.6, 1.8, xf86-video-intel 2.6.11, kernel 2.6.33 2.6.34 and 2.6.35-pre). Windows work fine on this hardware. I find reports for a similar bug, but it affect ati hardware. It seems this commit fixed ati cards. 267364ac17f6474c69b03034340f769b22f46105 drm/radeon/kms: further spread spectrum fixes. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/539350 https://bugzilla.redhat.com/show_bug.cgi?id=571874
The problem is also visible during boot process when kms is started, perhaps should i fill a kernel bug ? a drm bug ?
(In reply to comment #1) > The problem is also visible during boot process when kms is started, perhaps > should i fill a kernel bug ? a drm bug ? It's fine to stay under DRM component in this bugzilla.
