Re: Intel GM45 agp support


I have a GM45 integrated grahics. And I can run X without agp support
(but in 16bits only du to small memory problem). This is Xorg from
current pkgsrc.

I had the same broken display when returning to console but I resolve
this with the followings options for the intel Xorg driver:

Option          "DRI"           "Off"
Option          "SWCursor"      "On"
Option          "Tiling"        "On"
Option          "DDC"           "On"
Option          "XVideo"        "On"
Option          "PageFlip"      "On"
Option          "TripleBuffer"  "Off"
Option          "AccelMethod"   "XAA"
Option          "XvMC"          "On"
Option          "MTRR"          "On"

Returning to console works fine. And not problem to stop and
restart X. 

I will try your patch as soon as possible.
