As far as I remember we changed CONFIG_DRM_VMWGFX_FBCON to 'y ' now. Generally it is getting more complicated nowadays. Grub2 initializes some framebuffer graphics mode (unless console mode is enforced in /etc/default/grub), hands this fb over to plymouth and that hands things over to X. And somewhere between grub and plymouth starting, the kernel may start a gfx device specific modeset driver which may have its own fb driver. Many opportunities for things to go wrong. Btw, I think I mentioned it before but the vga= argument may be becoming more a problem than helping. Grub sets a gfx mode already and that is kept if no modeset driver is not changing it. And all newer modeset drivers use video= for specifying the preferred resolution. (like video=1280x800@32). But in theory that should not be necessary at all when the gfx mode is set ok by grub. Anyway, I tend to declare this bug as "fixed" and have people with other gfx cards/drivers open individual bug reports. Mixing things in one single report will only cause confusion.

Grub boots up with 800x600, switches back to 640x480 (setting GRUB_GFXPAYLOAD to "keep" it is the same) kernel doesn't switch back to 800x600. Adding deprecated "vga=768" back in: Grub boots up with 800x600, switches back to 640x480, kernel switches back to 800x600, but doesn't use this console. No output at all. Keys are accepted (you can login, but you'll have to guess what is going on on the screen). Exactly the same error is found with debian. Switching to a self compiled kernel solves this error. Looks a lot like some necessary stuff for console resolution switching is missing in the debian -/ubuntu-kernels.
