185.19 colors flashing on shutdown?

I'm testing the 185.19 drivers (x64) on the Ubuntu Jaunty 9.04 RC (with all updates).
When I shut down, the machine begins shutdown as expected. The screen goes blank, the backlight goes out, but then a second later, the backlight comes back on. Then it cycles through a full screen red, green, blue and white screen before shutting down.
This behaviour did not happen before installing the nvidia drivers.

Anyone else seen something similar?

The Ubuntu Intrepid graphical shutdown thing has a bug where it doesn't draw the whole screen, resulting in flashing colors on the bottom half. I haven't tried Jaunty's graphical shutdown, but it wouldn't surprise me if it has a similar bug.

A workaround I found is to enable the graphical framebuffer using vesafb or uvesafb. If you google around on the Web, you can find a howto for this.

Ahah! Thanks for the tip.

I have vga=892 in my 8.04 install, so that was automagically loading vesafb.
Tried the same in 9.04 and no more flashing colors. The shutdown screen looks weird - all sorts of wrong colors, but I expect that's to do with 8 bits screen mode etc.

Yes, that is correct about the shutdown screen being corrupted. If you use a mode with 24-bit color, then that problem will not occur.
