LCD compatibility on GM45 laptops

+ +

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

+ +

+ Back to previous index. +

+ +

The problem

+ In some cases, backlight turns on during boot, sometimes not. In all cases, + no display is shown in GRUB, nor in GNU/Linux. +

+ Current workaround: +

+ T500/R400 are clones of the T400. See coreboot/src/mainboard/lenovo/t400/devicetree.cb in libreboot, + and note that register "gfx.lvds_dual_channel" = "0" - in other words, single channel LVDS mode is + enforced. This works on the lower resolution panels (1280x800), but not on the higher ones. +

+ For the high-res panels, re-compiling with register "gfx.lvds_dual_channel" = "1" partially solves + the problem for those displays; there is still no display in GRUB, but once the kernel takes over, there + is a display. +

+ 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. +

+ +

EDID

+ +

+ One T500 had a screen (1920x1200) that is currently incompatible. Working to fix it. EDID: +
