I'm guessing that this computer does not actually have a HDMI connector
- is that correct?
If so, there is a kernel patch upstream which should fix the issue:
drivers/gpu/drm/radeon/radeon_connectors.c
/* TOSHIBA Satellite L300D with ATI Mobility Radeon x1100
+ * (RS690M) sends data to i2c bus for a HDMI connector that
+ * is not implemented */
+ if ((dev->pdev->device == 0x791f) &&
+ (dev->pdev->subsystem_vendor == 0x1179) &&
+ (dev->pdev->subsystem_device == 0xff68)) {
+ if ((connector_type == DRM_MODE_CONNECTOR_HDMIA) &&
+ (supported_device == ATOM_DEVICE_DFP2_SUPPORT))
+ return true;
+ }
This patch should be included in kernel 3.1-rc4. A PPA of this kernel
will be available at http://kernel.ubuntu.com/~kernel-ppa/mainline/
