1024*768*4 = 3145728 bytes or just over 3mb. That's at 1024x768. So, 4mb is enough to support this resolution. The graphics mode comes up, it works fine. It's always worked fine in Windows, with 8mb. Additionally, I'm not doing any animation, where'd I'd need more than 1 buffer, I'm just running Gnome. I really don't think the RAM is the issue. I'd say it must be something to do with how the refresh is set up. But the configuration files for specifying these things is very technical, and while I'm technically inclined, I really don't have time to dig into how all the parameters work, plus there's always the possibility of damaging the monitor. Thanks for looking at this for me! --Steven PS. The reason I didn't want to trim is that I didn't know what information would be useful. I didn't want to trim something important out. >-----Original Message----- >From: fedora-list-bounces@xxxxxxxxxx >[mailto:fedora-list-bounces@xxxxxxxxxx] On Behalf Of ne... >Sent: Wednesday, August 04, 2004 4:51 AM >To: For users of Fedora Core releases >Subject: RE: Graphics Card or Monitor problem, how to fix? > >On Aug 3, 2004 at 17:08, Steven Hodgen in a soothing rage wrote: > >[TOP POSTING REARRANGED] > >>Then I replied >>>On Aug 3, 2004 at 10:55, Steven Hodgen in a soothing rage wrote: >>> >>>>Hello, >>>> >>>>I've installed Fedora on an old Dell Dimension L566cx.
