I'm running kdm as my display manager on an HP pavilion laptop with a VIA |
| 2 |
Ultrachrom (TwisterK) video chipset. |
| 3 |
On that I'm running monolithic kde 3.5.2 on xorg-x11 7.1 |

|

On the initial startup everything comes up fine. I see these messages in |
| 6 |
/var/log/Xorg.0.log |

I've googled for drmSetBusid and "Permission denied" and the consensus seems |
| 59 |
to be a gcc version mismatch between the kernel and the drm module. I know |
| 60 |
that's not the case, because I've re-emerged my entire system using |
| 61 |
gcc-4.1.1 There's also the fact that it worked the first time. |
| 62 |
|
| 63 |
Another puzzle is that the first time through the savage drm reported "DRM |
| 64 |
interface version 1.2", but the second time it reported "DRM interface |
| 65 |
version 1.0", then failed calling drmSetBusid. I've gone through my |
| 66 |
installation and I don't see any dups of kernel modules or shared objects. |
| 67 |
Any ideas as to the source of the conflicting version? |
| 68 |
|
| 69 |
And, why does this cause a segfault in the ramdac library? |
