Yeah, that's completely impenetrable to someone who doesn't already know what it means. =) I guess we're talking about an xorg.conf with "Accel" "Off", right? (Does that disable 3D acceleration?) Remember we have xorg.conf.d snippets, now - can we provide some such snippets ready-made for use on the test day page? 'moving dri drivers out of the way' is referring to the files in libdir/dri . What I have there is: /usr/lib64/dri/i915_dri.so - early intel (rename this to test blacklisted intel chips) /usr/lib64/dri/i965_dri.so - late intel /usr/lib64/dri/nouveau_dri.so - late nouveau /usr/lib64/dri/nouveau_vieux_dri.so - early nouveau (rename this to test old nvidia chips) /usr/lib64/dri/r200_dri.so - early radeon (rename this to test blacklisted radeon chips) /usr/lib64/dri/r300_dri.so - mid radeon /usr/lib64/dri/r600_dri.so - late radeon /usr/lib64/dri/radeon_dri.so - is this really really old radeon? /usr/lib64/dri/swrast_dri.so - software rendering? /usr/lib64/dri/vmwgfx_dri.so - vmware passthrough? so specifically, if you have an old blacklisted Intel chip, you can move /usr/lib64/dri/i915_dri.so out of the way in order to try it with software rendering. If you have an old blacklisted Radeon chip, you can move /usr/lib64/dri/r200_dri.so or possibly /usr/lib64/dri/radeon_dri.so out of the way to test it. If you have an old (not blacklisted, we didn't blacklist them yet, but some of them are pretty wonky at running shell) NVIDIA chip, you can move /usr/lib64/dri/nouveau_vieux_dri.so out of the way to try it. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
