vbtracetool vBIOS dump
Starting X with git nouveau and Randr12 disabled works perfectly.
Enabling Randr12 gives a somewhat corrupted screen which is predominantly red.
My system is a Dell Inspiron 5150 with a 1600x1200 screen and an nv34m.
The corruption is only on the internal panel. Any external screen on the VGA
output seems to be fine.
Bug #14403 seemed to be the closest to my experience and so I messed around
with nv_bios.c.
In the function parse_lvds_manufacturer_table_init the section labeled:
/* adjust some things if straps are invalid (implies the panel has EDID) */
resets the lvdsmanufacturerindex from 3 to 0.
Putting in a line to set this back to 3 (or indeed 1 or 2) makes everything
seem to work fine.
I did a BIOS dump with vbtracetool. Does this help?
