Hi,
I have a VX900 laptop that got broken twice between openchrome 0.5.0 and
0.6.0.
First breakage comes from the update of the panel resolution table with
the table from viafb. 0xA got changed from 1368x768 to 1024x768. I'm not
sure why the viafb table was assumed to be better than openchrome table,
but at least in this case, it proved to be wrong.
Faulty commit : d90a71c7146470162cb2bd1f76f9c5cfcec09101
Fix : attached patch.
Second breakage is unconditionally setting the flat panel to IGA2 for
the VX900. The VX900 is the only chipset which was allowed to be on
either IGA1 or IGA2, all older chipsets had the FP already fixed to
IGA2. For whatever reason, this doesn't work for this laptop, which then
only displays a garbled screen.
Faulty commit : 6b66a9ec3c0c3caf75e804f0abe19871df014c4b
Fix : revert the commit.
Happy to provide more testing or info if needed.
Regards,
Xavier
