Update (vljn): Meego and its netbook ux actually works on non SSE/SSSE3 supporting Pentium 4. The issue is that most non ssse3 chipset comes either with a too old intel gfx, or with an intel/amd graphic chipset. Both are not supported out of the box.

MeeGo on nonSSSE3 x86 Hardware

Update (vljn): Meego and its netbook ux actually works on non SSE/SSSE3 supporting Pentium 4. The issue is that most non ssse3 chipset comes either with a too old intel gfx, or with an intel/amd graphic chipset. Both are not supported out of the box.

This page was inspired by a discussion on #meego (log@21:17) regarding MeeGo support of nonSSSE3 based hardware.

lbt added to the discussions with a timely blog post he had been working on http://mer-l-in.blogspot.com/2010/08/are-intel-subverting-meegocom.html.
