Any specific AGP settings you had, such as "AGPMode" or "AGPSize" will be deactivated though. This is not a solution but hopefully a way to avoid the lock ups and still have _some_ 3D acceleration until the problem gets fixed properly. Please remember to provide feedback as to whether it eliminates the lock ups or not. > -------Original Message------- > From: Glenn Johnson > Sent: 08/26/03 02:54 PM > To: Sean_Welch@alum.wofford.org > Subject: Re: Radeon 7500 w/ DRI locking on restart of X > > > > On Tue, Aug 26, 2003 at 12:21:56PM -0500, Sean Welch wrote: > > > Is anyone else seeing this issue? > > Yes, I have a Radeon 9100 that does the same thing.
