Cc'ing drm. I conclude further tests. * Linux 2.6.35-rc2 - fbcon:radeondrmfb using "modprobe radeon modeset=1" - sound ok - Xorg (7.4) with 'radeonhd' - fbcon ok, no sound in Xorg - I figure radeonhd is obsolete - Xorg with 'radeon' - fbcon ok, xorg ok. There is a small breakdown when switching between fbcon and xorg * Linux 2.6.33.5 - like 2.6.35-rc2, but had a bug that prevented radeon.ko to go into graphics mode when initially loaded; workaround: modprobe fglrx; rmmod fglrx; modprobe radeon modeset=1 - or fglrx, also makes sound work - fglrx bug aside: switching from Xorg to console (either 80x25 or radeondrmfb) makes a fugly "pop" noise, and if the target is radeomdrmfb, display is garbled. So I'm happy. Conclusive questions however: * Why is it that I am only allowed to have sound in graphics mode? * The radeon.ko module does not have any PCI IDs defined, thus does not get autoloaded like i915.ko. Is this intentional? It also seems to default to modeset=0. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
