No. The driver from unstable is fine with EXA and the one from experimental works fine with UXA. It's fine with me if you close the bug. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 713 440 7475 | http://crustytoothpaste.ath.cx/~bmc | My opinion only OpenPGP: RSA v4 4096b 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187 signature.asc Description: Digital signature

Everything is working now, using driver from unstable, with or without UXA. Cheers, Julien -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

And from unstable or experimental where UXA replaces/improves EXA? Brice -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

It seems it's already present in > libgl1-mesa-dri. At the very least, you need libdrm and the i915 kernel module from the drm Git branch i915tex-compat. I'm not sure it'll work without rebuilding Mesa and/or xf86-video-intel (2.1; 2.2 is incompatible with i915tex, it requires the i915 driver from mesa Git master for this) though. Then you'll need Option "Legacy3D" "off" to make it use i915tex instead of i915. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer

XaaNoOffscreenPixmaps just happens to make it usable, at the cost of basically disabling 2D acceleration. While the same workaround could be implemented for EXA, there's little point in using it (or XAA, for that matter) at all in that case. So there's really no point in implementing such an option for EXA, compared to just switching to XAA. With the i915tex Mesa driver (or the i915 driver from upstream Git, but that also requires xserver Git), EXA allows for more efficient GLX_EXT_texture_from_pixmap together with 2D acceleration, but unfortunately this is difficult to set up. It's all kind of messy at the moment, but work is going on upstream to make it all work nicely out of the box in the hopefully not too distant future. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer

I am not sure it is related, but the shadows around the windows are not smooth with the new xserver-xorg-video-intel They look like oblong gradient around the windows.

Bug#451571: xserver-xorg-video-intel: uses lots of CPU with Compiz and (new default) EXA
Package: xserver-xorg-video-intel Version: 2:2.2.0-1 Severity: important The intel video driver now uses EXA by default. When using Compiz as my window manager, Xorg consistently uses >50% of the CPU when scrolling in Firefox or doing other simple (and formerly efficient) operations. This did not occur with XAA, because I used XAANoOffscreenPixmaps, which is recommended with Compiz. Now, using EXA, offscreen memory is allocated, which I believe to be the cause of the CPU waste.
