Hi Tarek,
I think you have proved now that the network is good.
You are loosing single packets acording to the utcapture results
Collumn 6 " Percentage Packets lost" is blank so you should be good.
Your problem is not the network.
Can you describe the "blinking pixels" more in detail ? when do
they appear ?
Is the SUN 24.1" screen connected to the SR3 using VGA or DVI
cables ?
Are you using the top DVI connector on the SR3+ for the first ( or
only) Display unit ?
Are you using short ( less than 3 meters ) DVI cables ?
Are you using KVM - switches between the Display and the Sun-Ray ?

Thank you Lars, I contacted the help desk of the department to see
how I can change that setting (I am a student and I am maintaining
the servers in our group as the IT guys of our department do not
support Sun Ray servers since only our group uses them).
The urtcapture command returns this:

Does this confirm your explanation? and if I can change the
configuration myself please let me know, I only have access to the
server and DTUs.
Best Regards,
Tarek

Hi,
The "blinking pixels " could be explained by a
misconfigured network. Sun Rays use a protocol loaded into UDP
frames and it runs into problems if you have Switch-ports
which are hard configured to FULL DUPLEX or configured
to HALF DUPLEX You need to have you switch ports configured
to NEGOTIATE the line speed and duplex type.
There is also switches with no bufferhandleing when
switching from Gigabit to Fast ethernet. Here UDP frames
are also lost. Make sure UDP frames are propagated correctly
through your network.
The blue "smurf-like" Flash-videos with the Linux flash10
player is a well known problem
Download the Flash 9 player as documented here.

Hi everyone,
I am new to this mailing list. I am trying to setup new
terminals that we just received but I am having problems with
the graphics.
The problems are mainly with the Sun Ray 3 plus units. The
monitors are the Sun 24.1 LCD v4.
I get blinking/flashing pixels especially for the resolution
1920x1200 (If I select a lower resolution, there are fewer
blinking pixels but the display is smaller with black edges).
When I connect the same monitor directly to the Sun Ray
server, I don't have any problem.
The blinking problems does not appear in the Sun Ray 270
units but when I try a youtube video, the picture is bluish...
SSRS 4.2
SLES 10 SP2
Nvidia GT220, 1GB RAM
Dell with 16GB RAM
Your help is really appreciated,
Thanks,
Tarek
