We have already talked with plaes on IRC yesterday, just now bringing it here. I have finally updated the http://linux-sunxi.org/LCD page to add LVDS panels data and now for Gemei_G9 we have the following settings there:
CONFIG_VIDEO_LCD_MODE="x:1024,y:768,depth:24,pclk_khz:100000,le:799,ri:260,up:15,lo:16,hs:1,vs:1,sync:3,vmode:0" CONFIG_VIDEO_LCD_PANEL_LVDS=y # warning: unsupported 'lcd_lvds_mode' : 1 CONFIG_VIDEO_LCD_POWER="PH8" CONFIG_VIDEO_LCD_BL_EN="PH7" CONFIG_VIDEO_LCD_BL_PWM="PB2"
It's good that lcd_lvds_mode=1 apparently works without problems, while this was not fully expected according to http://lists.denx.de/pipermail/u-boot/2015-January/200168.html
Also confirming whether 18-bit or 24-bit is the correct color depth would be a good idea. This tablet has 'lcd_frm = 1' and 'lcd_lvds_bitwidth = 0' in fex.
