I'll have to double check, but I don't recall having any problems with mode switching in tuxracer last time I played with it. Steve, what chip are you running on? bios or non-bios mode setting? it also might be an issue with the backbuffer overwriting the front buffer. see below. > > I don't know why drawpix to the backbuffer works for me but not for > you. > I'll look into this some time.

One of these days, maybe this weekend, I'll put a quick check in the buffer allocation code in savage_accel.c to make sure there is enough memory for 3D in the current mode/depth. <OT> I haven't really been testing the trunk to much lately, as I've been messing around with duoview support. I've just about got it working. I can set up the second controller and dot clock, I just can't get it to produce a signal. it's driving me nuts...</OT> Alex > > Regards, > Felix > > Begin forwarded message: > > Date: Fri, 27 Feb 2004 11:59:22 -0600 > From: Steve Holland <[EMAIL PROTECTED]> > To: Felix Kühling <[EMAIL PROTECTED]> > Subject: Re: [Dri-devel] savage-2-0-0 test notes > > > I tested it with a fresh copy from the trunk (effective tuesday), and > have the same problems. > > Here are some PNG's of the results from drawpix: > 16 bit display, drawing to back buffer: > http://69.5.151.193/~sdh4/drawpix16bit.png > drawing to front buffer: > http://69.5.151.193/~sdh4/drawpix16bitfrontbuffer.png > 24 bit display drawing to back buffer: > http://69.5.151.193/~sdh4/drawpix24bit.png > (24 bit display drawing to front buffer was similar to 16->front > buffer) > > I also noticed problems when switching video modes on a 24 bit > display. > For example, running tuxracer would get the display parameters wrong, > > leading to an incomprehensible display (even after quitting). > > Thanks, > Steve > > > > On Tue, 2004-02-24 at 07:13, Felix Kühling wrote: > > On Mon, 23 Feb 2004 14:18:53 -0600 > > Steve Holland <[EMAIL PROTECTED]> wrote: > [snip] > > __________________________________ Do you Yahoo!?
