Description David Balažic 2000-06-19 13:25:56 EDT
During GUI install, if I switch to VT1 after the DDC monitor probing, then 
I get a black screen with vertical blue lines. Switching thru other text 
consoles has no visible effect. Switch to VT7 ( the X server ) is OK. After 
that I can switch to text VTs and the problem is gone.
To reproduce it run /mnt/runtime/usr/sbin/ddcprobe while the X server is 
displayed ( switch to VT7 ).

gfx card : Diamond Viper 550AGP ( 16 MB RAM, rivaTNT )
monitor  : Hyundai 7695

Still there in beta2.
I also noticed that when I press ctrl-alt-f1 it on the monitor
selection screen , it doesn't work at first. The second press gives
a screen with blue stripes.

Please verify in test lab.
Comment 3 Glen Foster 2000-07-18 14:54:01 EDT
This defect is considered MUST-FIX for Winston Beta-5
Comment 4 Glen Foster 2000-07-21 14:40:14 EDT
Does this defect still exist with (on) Winston beta-4?
Comment 5 Michael Fulbright 2000-07-27 14:35:03 EDT
Is this a problem in beta 5?
Comment 6 David Balažic 2000-08-16 05:11:52 EDT
Yes it is ( a problem in beta 5 ).
Comment 7 Michael Fulbright 2000-08-17 17:12:37 EDT
Sounds like a kudzu issue.
Comment 8 Bill Nottingham 2000-08-17 17:17:38 EDT
Can someone verify this in the test lab?
Comment 9 David Balažic 2000-08-22 08:06:46 EDT
There in RC1 too
Comment 10 Bill Nottingham 2001-02-01 17:16:36 EST
Can someone *please* verify this on a machine here? Without
that, we really have no chance of fixing it.

I've gotten reports that XFree86 4.0.2 fixes this after release 9 or so.
Please try out XFree86 4.0.3-1 and Mesa 3.4-13 from:


It should solve this problem for you.  Does it?
Comment 15 Bill Nottingham 2001-03-21 01:57:39 EST
The DDC probe isn't even by default in kudzu anymore (it is called by
Xconfigurator, though.)
Comment 16 Bill Nottingham 2005-02-04 17:44:02 EST
Closing out bugs on older, no longer supported releases. Apologies for any lack
