Hi Rob, Thanks for your detailed explanation.
According to Bryce, we have high enough versions of Xorg stuff in hardy for everything to work; the only remaining issue according to Amit is that we might need a newer drm kernel module as Intel seems to target drm git HEAD instead of kernel.org git HEAD or Ubuntu's kernel HEAD (which causes lots of pain). So again, this is not an issue for hardy which is what we target for the release and should hopefully switch to. The issue only affects UME for the interim period where we work on gutsy + ubuntu-mobile's gutsy ppa because Intel folks want to work on GL related stuff -- correct me if I'm wrong!

Bryce was kind of enough to explain to me that updating libexa for gutsy to 2.2 would require updating some 6 or 12 modules as well which is an amount of backports we're not prepared to do for an interim situation. What /might/ be doable is backporting only specific patches identified by Intel to the libexa 2.1 tree, just enough to make Poulsbo work and as little as possible in general. If you can point out what small changes we could do to libexa 2.1, then we might get this reviewed and backported for the interim period. > Proposal 2: > ========== > Another idea is to live without 2D acceleration until we switch to Hardy > and we move the PSB Gfx driver to xorg 1.4.

This sounds like the sanest approach to me. Backporting a new libexa version seems very intrusive and painful to me. -- Loïc Minier -- Ubuntu-mobile mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-mobile
