+
+ <p>
+ On the T400 and T500 (maybe others), some of the higher resolution panels
+ (e.g. 1440x900, 1680x1050, 1920x1200) fail in libreboot.

+ <h1>The problem</h1>
+ <p>
+ In some cases, backlight turns on during boot, sometimes not. In all cases,
+ no display is shown in GRUB, nor in GNU/Linux.
+ </p>
+ <h1>
+ Current workaround:
+ </h1>
+ <p>
+ T500/R400 are clones of the T400. See <b>coreboot/src/mainboard/lenovo/t400/devicetree.cb</b> in libreboot,
+ and note that <b>register "gfx.lvds_dual_channel" = "0"</b> - in other words, single channel LVDS mode is
+ enforced. This works on the lower resolution panels (1280x800), but not on the higher ones.
+ </p>
+ <p>
+ For the high-res panels, re-compiling with <b>register "gfx.lvds_dual_channel" = "1"</b> partially solves
+ the problem for those displays; there is still no display in GRUB, but once the kernel takes over, there
+ is a display.
+ </p>
+ <p>
+ Linux (kernel) has its own init code (including EDID parsing). The current suspicion is that coreboot's
+ own initialization code has buggy EDID parsing in some way, such that the proper settings for the panel
+ are not used, leading to the failure. The actual graphics initialization does work.
