--- Comment #10 from Alex Deucher alexdeucher@gmail.com --- (In reply to kristof from comment #9)
By checking my Xorg.0.log, I realized that "EXA" submodule is loaded instead "glamor" ... (noticed in my workaround firmware non-free installed + mesalib not patched) Since my gpu is a R300 (RV380-X600) family submodule should be "glamor", right or mistake from me due to misunderstanding something ?
All pre-SI cards use EXA by default. I'm not even sure the r300 cards are capable of using glamor anymore.
