About fixing remaining LCD panels on 5345:<br/>
- 'polarity' is mentioned in coreboot log (cbmem
-c). compare output (with working and non-working panel). (and see the other
notes in docs/future/index.html)<br/>
- phcoder says: hint for T60: it might be that
failing panels are 8bpc<br/>
- fchmmr: what does 8bpc mean? And what do you
think the other (non-failing) panel are?<br/>
- phcoder: 6bpc. bits per colour. May also be
reffered as 18-bit vs 24-bit panels<br/>
- phcoder: just collect EDIDs from failing and
working panels<br/>
+ 'polarity' is mentioned in coreboot log (cbmem
-c). compare output (with working and non-working panel). (and see the other
notes in docs/future/index.html)</p>
+ <p>There was a theory that working panels are
+ 6bpc (bits per colour) and nonworking are
+ 8bpc, but all EDIDs that we have here are
+ for 6bpc panels.</p>
+ <p>We should compare coreboot logs
+ (from <code>cbmem -c</code> from systems with
+ working and nonworking panels.</p>
+ <p>How to dump EDID:</p>
# <b>apt-get install i2c-tools</b><br/>
# <b>modprobe i2c-dev</b><br/>
