Description Wolfgang Rupprecht 2008-05-14 20:05:22 EDT
Description of problem:

My Matrox MGA 400 framebuffer has severe artifacts under F9.  It worked
perfectly under F8 just before the "upgrade".

Version-Release number of selected component (if applicable):

xorg-x11-drv-mga.i386                    1.4.8-1.fc9 

How reproducible:

Steps to Reproduce:
1. boot
2. notice the mangled screen.  The effect is a bit similar to 
   a TV with screwed up interlace.  Alternate lines are over by approx.
   an inch (at ~100dpi)
Actual results:
mangled screen output

Expected results:
clean screen output

Additional info:
strangely the ascii terminals on alt-ctl-Fn also have a bug (perhaps related?)
Every other letter is missing.  This is also a new bug since fedora-8.

I forgot to mention, the garbled graphics also exists in the fedora-9 installer.
 It is possible to install anyway, which I did, hoping it was just an installer

this has been fixed for a while in the current fedora.  Feel free to close.
