This is not true. While the plan is to get stop using device specific ddx drivers you do not need modesetting for "new intel processors" they works with the intel ddx as well. > plus accelerated compositing is known-broken > in WebKit; we unfortunately cannot support that combination.

Its not broken with Firefox or LibreOffice ... it can by design not work remotely. This issue has been fixed in xserver git by transparently fallback to DRI2 in that case -> https://bugs.freedesktop.org/show_bug.cgi?id=93261 Also XWayland only supports DRI3; and DRI3 on X is a requirement for Vulkan. It also helps compositors like mutter to avoid tearing and improves performance. So if there are issues with WebKit they should be fixed. "It can't work lets go back to DRI2" isn't really an option in the long run -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
