My hardware (i855gm on sony vaio x505vp) never worked with i810 driver
of any xorg release. The error is always the same with any
configuration option:
(WW) I810(1): Extended BIOS function 0x5f1c not supported.
Is the warning always present,
I've tried various configuration, starting with the external CRT
device attached, with CRT+LFP on pipe A, on pipe B, CRT on pipe A and
LFP on pipe B, CRT on pipe B and LFP on pipe A, configuring all the
possible combination of pipe and driver options.
The result is or an X crash (no attached device) or X fire up with
only CRT or only LFP.
I've never been able to start in real Dual Head with xinerama and the
best i can get is Clone mode working.
The most singificative logs are in the bug report, but if someone need
I'll make all the test again.
Greetings
