- Subject: [PATCH 14/18] lenovo/x230: introduce FHD variant
- There is a modification for the x230 which uses the 2nd DP from the dock
- as the integrated panel's connection, which allows using a custom eDP
- panel instead of the stock LVDS display.
- There are several adapter boards present on the market and all of them
- uses the same method of enabling the custom eDP panel.
- To make this work with coreboot, the internal LVDS connector should be
- disabled in libgfxinit. The VBT has been modified as well, which allows
- brightness controls to work out of the box.
- The modifications done to the VBT are:
- - Remove the LVDS port entry.
- - Move the DP-3 (which is the 2nd DP on the dock) entry to the first
- position on the list.
- - Set the DP-3 as internally connected.
- This has been reported to work with the following panels:
- - LP125WF2-SPB4 (1920*1080, 12.5")
- - LQ125T1JW02 (2560*1440, 12.5")
- - LQ133M1JW21 (1920*1080, 13.3")
- - LTN133HL10-201 (1920*1080, 13.3")
- - B133HAN04.6 (1920*1080, 13.3")
- - B133QAN02.0 (2560*1600, 13.3")
- Other eDP panels not on this list should work as well.
