Re: Re: Can't see the Panel after installation of Redhat 7 on 5000e. Help!!
- For what it's worth, I was seeing similar freeze-ups and funky screen
colors on my CPx H500GT running Mandrake 7.1 with XF86 4.0. The
problem went away when I ``disabled'' screen-blanking by setting a
long BlankTime (2880 minutes) in XF86Config.
[Actually the long BlankTime is a ``temporary fix'' until I figure out
something better, but it did resolve the problem for me. YMMV....]
