does VMware 4.5.1 requires DGA in Xfree86?

i've installed VMware from Gentoo portage. after final configuration it seems to work fine. the problem appearers when i start a Virtual Machine. it prompts me that:

DGA extension not present. Either your X server is build without this extension, or it is not configured to use it. XFree86 direct graphics (DGA extension) initialization failed
well there is such a line in my /etc/X11/XF86Config:

    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension
i've tried commenting those lines, but the same error appeared.

i guess that wouldn't be a problem, but when i'm trying to install Windows XP on VMware, my Xserver crashes during partition formatting, and system stops responding a moment later. i've got no idea what is wrong, but i guess it's somehow related with that DGA problem. could anyone help me?

To enable DGA, you should only comment out the middle line :
    SubSection  "extmod"
#      Option    "omit xfree86-dga"   # don't initialise the DGA extension
Leave the other two as they are.

However, I doubt if this is the reason for the crash. Look through /var/log/XFree86.0.log for clues.

DGA does not work with a framebuffer. Don't run a framebuffer (hi-res console).

If you want to run vmware without DGA and don't want it to complain:

put xinfo.noDGA = TRUE in the vmx file or in preferences.ini

i've figured out what the problem was. i've allowed VM to use all my memory. that's why system used to feeze. now i've decreased that amount by half and everything works fine

I get the same message when vmware starts, but I don't bother much about it. :-)
I don't think you need the DGA to run a vmware normally. I had also tried unsuccessfully to use vmware with XP (an older vmware version). Only I had the XP already installed on a hd partition & the problem was that XP always stopped my CPU after XP had booted! It used to complain that "the o.s. sensed something else had DIRECT access to the hard disk" - i.e. the vmware had direct access to the hd, & as a "security measure" it stopped the CPU. The only way to fix the problem was installing a different windows version on that partition - now I have win2000 & it works ok. I am convinced that the real bug you've got is that XP...
