I have the same issue and have been trying to fix it for hours. I can set the resolution for the GRUB2 menu using gfxmode=1024x768x16 I can also set the initial resolution for the kernel boot using gfxpayload=keep or gfxpayload=1024x768x16 I even see the resolution change to the desired mode for a while, however the screen remains blank until the kernel switches back to text only 80x30 mode!
After doing dmesg I see this line: [ 12.831560] Console: switching to colour frame buffer device 80x30 I guess this is where the kernel switched back to text mode (Which is good since the gfx mode just remains blank!)
