blue stripes on text-VTs after DDC probing
Last modified: 2014-03-16 22:14:21 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.
This defect is considered MUST-FIX for Winston Beta-5

Is this a problem in beta 5?
Yes it is ( a problem in beta 5 ).
Sounds like a kudzu issue.
Can someone verify this in the test lab?
There in RC1 too
Can someone *please* verify this on a machine here? Without
that, we really have no chance of fixing it.
