Bug ID: 192462
Summary: vt has display issues when switching vty's
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: Normal
Component: kern
Assignee: [email protected]
Reporter: [email protected]
issues #2 and #4 from:
https://www.freebsd.org/cgi/[email protected]
Second, once one vty has the gallant font loaded, if you switch vty's,
it can occure that the new vty does not display ANY text.. The display
is mostly blank...
and:
Fourth, when switching screens, there is a brief flash of vertical
stripes before the new screen comes on... Can we do something to make
sure that this transition is clean? Either a completely blank screen,
or ideally, no blank screen, but the new text appearing?
There are issues w/ font loading and display switching w/ the vt_vga
display driver...
Environment:
System: FreeBSD carbon.funkthat.com 11.0-CURRENT FreeBSD 11.0-CURRENT #2: Tue
Aug 5 16:40:10 PDT 2014
[email protected]:/usr/home/jmg/freebsd.p4/opencrypto/sys/amd64/compile/GENERIC
amd64
kern.vty=vt
How-To-Repeat:
load a font (for #2) and then just randomly switch between vty's...
Very randomly (it may take 10 or 20 tries) the console will not display
anything.. If you switch away and back again, there will be text...
Also, looking closely when switching vty's, there is "junk", in my case,
vertical lines, that is displayed between the text of the two vty's...
Fix:
unknown..
