Note: When the console resolution is changed using the
methods outlined in Appendix A, the output will default to Monitor
0 unless the “tsi-default-head” variable is set as described
below:
This behavior can be overridden by the tsi-default-head
variable as in the following nvramrc setting.
For example, to set the default console to Monitor 1:
ok nvedit
0: 1 value tsi-default-head
1:
ok nvstore
ok setenv use-nvramrc? true
ok reset-all
NOTE: Head 0 is the DVI connector and head 1 is the DB15
connector.
If the GFX 450 is not the console device, the driver will still use
the same rule described above to determine which head should
be the default head.
To override this behavior, you can set the “tsi-default-
head”
variable in the
mko.conf
file under
/platform/sun4u/kernel/drv
.
