Hi, I tested the latest Daily Live CD with the new DRM with two different ATI GPUs. With the first one, a HD3200 IGP, the display turned off during boot. Once X started the display turned back on and there were no further issues. Note that this was also happening with a Live CD with the old DRM. I suspect this issue is caused by Plymouth as more people have reported problems with Plymouth. With the second one, a HD5750, things were exactly the reverse. All went fine during boot, but at the end of the boot the display turned off and there was nothing I could do but reset the computer. There's no support for this GPU in the 2.6.33 DRM, there's in drm-next git. On a side note: Dave Airlie recently fixed a bug in Mesa that made Blender practically unusable with R600+ GPUs. Since Blender is quite a popular application it would be nice if we can have this bug fix in before Lucid is released. http://cgit.freedesktop.org/mesa/mesa/commit/?h=mesa_7_7_branch&id=cf8af9bcf127e170b64112bd548d5d4e79c8e894 -- Ubuntu-x mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-x
