Device
Suggested
action
Remote
control
does
not
work
with
default
SuSE
Linux
version
8.0
display
settings.
The
remote
console
requires
a
display
setting
of
1024x768@60Hz
in
the
blade
server
operating
system.
The
default
resolution
in
SuSE
is
1024x768,
but
the
default
refresh
rate
falls
somewhere
between
50Hz
and
60Hz.
The
remote
console
does
not
work
for
a
blade
server
running
SuSE
with
a
display
refresh
rate
other
than
exactly
60Hz.
The
message
“eServer/No
video
available”
displays.
Other
operating
systems
do
not
exhibit
the
problem.
Set
the
refresh
rate
in
the
XF86Config
file
to
exactly
60Hz.
There
are
two
methods.
v
Method
1
(unattended
network
install,
prevent
the
problem):
Modify
the
AutoYaST
control
file
to
specify
1024x768@60Hz.
1.
Run
the
graphical
interface
to
the
AutoYaST
control
file
to
set
the
VESA
video
mode
to
1040x768@60Hz.
The
graphical
interface
creates
the
AutoYaST
control
file.
2.
Edit
the
resulting
AutoYaST
control
file
to
set
the
value
for
min_vsync
to
60
.
During
an
unattended
network
install,
the
YaST
program
uses
the
AutoYaST
control
file
to
modify
the
XF86Config
file
(/etc/X11/XF86Config);
these
changes
will
cause
XF86Config
to
set
the
display
resolution
to
1040x768
with
a
refresh
rate
of
60Hz.
--
OR
--
v
Method
2
(situation
has
already
occurred):
Modify
the
xF86Config
file.
1.
In
the
Monitor
section
of
/etc/X11/XF86Config
,
change
the
value
of
VertRefresh
to
60
,
as
shown
in
these
sample
lines.

If
the

operating
system
is

remotely
onto
a
blade
server
that
is
not
the
current

SuSE
sees
the

establish
a

follows:
1.
Enter
the
following
command:
rm
