[Bug 58721] Re: Edgy upgrade breaks multiple Matrox cards

[clubsoda]

Update: I have discovered that the flickering problems are associated
with the framebuffer.  (Perhaps because my AGP 1x interface is too
slow?)  The flickering is subtle but can easily be seen by clicking on
the "Quit" icon to exit Ubuntu while you still have a terminal window
open, or any other large black spaces on the screen.  These will go
crazy colours and dance around a bit...

However, if I disable the framebuffer in both xorg.conf and /etc/modules
and try what Thomas did in his original post, i.e. replace "mga" with
"vesa", it works!  Not only pristine 1280x1024 text but glxgears too.
(Ahem, please don't ask about the frame rate. :)  One small issue: if I
go into Display Settings and change the resolution, X crashes.

Someone please reassure me that when the mga driver is working properly
I won't need the framebuffer.
