The current xf86-video-ati package 6.7.195 doesn't want to work on my MacMini, it errors with: (WW) ****INVALID IO ALLOCATION**** b: 0xf0000400 e: 0xf00004ff correcting (EE) end of block range 0xefffffff < begin 0xf0000000 (II) Module "ddc" already built-in (II) Module "i2c" already built-in finished output detect: 0 finished output detect: 1 finished output detect: 2 finished all detect before xf86InitialConfiguration (EE) RADEON(0): No valid modes. (EE) Screen(s) found, but none have a usable configuration. Fatal server error: no screens found Rebuilding xf86-video-ati version 6.6.3 seems to fix it though it still has the following: (WW) ****INVALID IO ALLOCATION**** b: 0xf0000400 e: 0xf00004ff correcting (EE) end of block range 0xefffffff < begin 0xf0000000 (**) RADEON(0): RADEONPreInit (II) Module "ddc" already built-in (II) Module "i2c" already built-in (II) Module "ramdac" already built-in (**) RADEON(0): RADEONScreenInit 98000000 0 But at least this one works. Any suggestions on what the problem might be? I'll go ahead and attach the full error from the current driver and also my xorg.conf.
