Some 3D works in Kubuntu 12.04 but isn't accelerated. x1250 + xserver-xorg-video-radeon 1:6.14.99~git20111219.aacbd629-0ubuntu2

Maybe there is a pattern here...
The only problem I can recall having is that I've never been able to get video acceleration to work. Neither with Ironlake or SNB.

Nothing was dropped from X. 2D accel is provided by UXA or SNA. And like I said, SNA explicitly supports 8xx. But it's not default yet, so make extra sure your xf86-video-intel is compiled with it. And use the latest version of course, which is 2.19
Edit: When I talk about 8xx above, I mean Gen2 hardware. I mention this because there's also i810, which is Gen1.Last edited by Gusar; 10 May 2012, 07:52 AM.

The graphs on phoronix tend to have similar colours which makes then often really difficult to interpret.

Sorry your right it was of cause mesa and not Xorg that doped the DRI1 drivers. However not enabled by default and in -dev doesn't count as working in my book, but its good to see that it is being worked on

- concerning modesetting, there's no KMS, but X should have the correct resolution. no idea about dual-screen, probably not supported
- concerning 2D, there's only XAA, which is useless nowadays, so you're basically without acceleration. you do get Xv for video playback, at least that
- concerning 3D, there is a kernel DRM module and a DRI1 driver. the intel manpage says only 16bit is supported, but no idea if even that still worksLast edited by Gusar; 10 May 2012, 12:21 PM.
