VMD-L Mailing List

Dear Mikko, VMD-L,
  Yes, we've seen those problems as well. I just got an email from
NVidia suggesting that we send detailed bug reports to their people here:
  linux-bugs_at_nvidia.com

I'm sure they'll want as much detail as you can give them. I'm planning on
attaching the XFree86 config files we're using, machine config info, etc.

I recommend anyone else that's having similar problems also file bug
reports, be sure to give them as much info as you can. You could always
include config files as email attachments, so they can scan your brief
description, but will have the other info as well. If I get any response
from their people I'll let the VMD-L list know, since I know this affects
quite a lot of people out there right now. Likewise, if anyone else
has suggestions or experiences to add to this discussion, please speak up :-)

Thanks,
  John Stone
