Description Joshua Buysse 2001-02-07 18:50:12 UTC
The console can be restored by killing gflux from a remote login.

Comment 1 Bill Nottingham 2001-02-07 18:53:47 UTC
G200, G400, r128, i810 or Voodoo?

Comment 2 Joshua Buysse 2001-02-07 18:56:23 UTC
The system has a r128.  Will add this system to the profiles on the beta site

The problem can also be reproduced by running /usr/X11R6/lib/xscreensaver/gflux
from the command line.  None of the other screensavers seem to show this behavior.

Comment 3 Bill Nottingham 2001-02-07 18:59:01 UTC
None of the other OpenGL screensavers do this?  Odd.
I'd still wager it's a DRI problem; does it go away if you
a) run in something other than 16bpp?
b) comment out 'Load "dri"' from /etc/X11/XF86Config-4?

Comment 4 Joshua Buysse 2001-02-07 19:05:53 UTC
You're right.  I hadn't tried a opengl screensaver, just a sampling of the
others.  All the opengl screensavers show the behavior, so it is likely dri.

The system is in a 32-bit mode, however, not 16-bit. I'm trying it without dri
support right now.

Comment 5 Bill Nottingham 2001-02-07 19:11:31 UTC
<wanders over to test machine>

Oh, r128 supports DRI in 24bpp now. I did not know that.
In any case, reproduced here; it runs for a while and then it hangs.

Comment 6 Joshua Buysse 2001-02-07 19:13:39 UTC
Confirmed that it's a DRI issue by commenting out dri in the XF86Config-4 file,
posted bug against XFree86-Servers

Comment 7 Mike A. Harris 2001-02-09 03:06:24 UTC
I've also confirmed this bug to exist as well under similar conditions.

Solution right now is disable DRI.  XFree86 4.0.2 DRI blows goats.
From what it looks like, DRI is not supported on Radeon, broken on r128 and
Voodoo, and matrox cards don't work at all period (yet).  Unless there are
some quick fixups to XFree86 4.0.2 DRI, perhaps in 4.0.3, there's going
to be a lot of disabled DRI drivers.  I think the cause of this is that both
the XFree DRI code is incredibly new and untested, and also the 2.4.x kernel
code is mostly new and untested, especially in combination with XFree 4.0.2.

In order to get DRI working, one will have to go to dri CVS and play.
