Okay, this looks good. You are using the correct framebuffer driver (the |
| 60 |
ATI Radeon driver and not the OpenFirmware FB driver, which won't work |
| 61 |
for X) and it appears that your monitor is correctly responding with an |
| 62 |
EDID for autodetection. Can you try generating an X config file with xac |
| 63 |
and give that a try? If it doesn't work out of the box, try uncommenting |
| 64 |
the "UseFBDev" option and try both "true" and "false", sometimes the |
| 65 |
correct value is not autodetected by X. |
