After (checks watch) a little over two years I finally investigated the boot warning on my Thinkpad X13s and it was caused by the conservative timings warning in panel-edp.c . The X13s was sold with a variety of different panel versions; I have the 300 nit multi-touch variant.
I have been unable to secure panel documentation so the I copied the timings from NV133WUM-N63. The raw EDID is: 00 ff ff ff ff ff ff 00 09 e5 84 0a 00 00 00 00 1e 1f 01 04 a5 1d 12 78 03 5c 70 a6 51 4c 9c 26 0e 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 74 3c 80 a0 70 b0 28 40 30 20 36 00 1e b3 10 00 00 1a 00 00 00 fd 00 28 3c 4b 4b 10 01 0a 20 20 20 20 20 20 00 00 00 fe 00 42 4f 45 20 48 46 0a 20 20 20 20 20 20 00 00 00 fe 00 4e 56 31 33 33 57 55 4d 2d 54 30 31 0a 00 51 Signed-off-by: Daniel Thompson <[email protected]> --- Changes in v2: - 0 1 2 3 4 5 6 7 8 9 a b c d e f ... yes, it's coming back to me now!
