What value did you plug in for MaxLVMem?  

 

Keep in mind that you have several things working against you here:

Support for Multi-monitor was added to XA 4.5 R01.

You third monitor has different dimensions than the first two

30mb MaxLVBMem is 94% on your Session Pool Size.  Far exceeding the
recommended 35-40%

 

Try setting MaxLVMem to 17039360 and Session Pool size to 48 or 64.  Also
need to reboot once changed

Hi

Im still having some issues getting ICA Published Apps to work on
workstations that have 3 monitors.  The resolution on each monitor is 1440 x
900.  I have read the following Citrix documents in relation to overriding
the Citrix session memory defaults:

http://support.citrix.com/article/CTX113497
http://support.citrix.com/article/CTX115637

I tried to increase the Memory for Session Graphics to 30Mb by modifying the
MaxLVBMem registry key based on article CTX114497.  Since my server has 2Gb
RAM the SessionPoolSize setting should be set to 32Mb which should be
sufficient.  I did not create a key to override this default setting. I also
deselected the "Use Citrix Farm setting" on the Citrix server in question so
I can override the Citrix Default.  When I tried to start a Published App on
a 3 monitor client I get the following error:

"The following requested video mode was not available: 4160 x 1024 x 16 BPP.
The video mode has been set to the following mode: 3420 x 841 x 16 BPP.
Video mode restricted by system administrator.

Does anyone know how I can check the memory being used for SessionPoolSize?
This would then let me know if I need to add this key and set it to a number
larger than 32Mb.  The ICA session freezes as soon as the above error is
displayed.  Any assistance appreciated..

Angela

Beware that the article mentions to be applicable for PS 4.5 and higher. 

 

Nevertheless we used the settings as described to publish desktops with
5100*964*16 pixels from PS 4.0 to workstations with 4 screens. We noticed
however that the relevant setting tends to "reset itself" to 8192 on reboot,
which required us to implement a startup script to keep it active. All in
all our experience with large published desktops on PS 4.0 was less than
delectable and we're looking forward to deploy XenApp 5 for these
applications.

The max color depth for ICA is 24-bit so the multiplier is 3, not 4.

 

This article answers your multi-monitor questions. There is a reg key that
allows you to specify graphics memory beyond 8192.

I'm not sure how ICA handles multi-monitor with different resolutions on
each monitor.

Hi

Further to this, if I set all 3 monitors to 1024*768, all 3 monitors work
fine.  If I set all 3 monitors to 1440*900 the third monitor doesnt work.
It looks like there is a max resolution limit or the session is running out
of graphics memory.

How can I check to see how much Display memory is in use?.  I changed the
Farm setting "Maximum memory to use for each session's graphics" to the max
which is 8192 but I continue to have the issue when working on the max
resolution.

Thanks
Ang

Hi

We have some users that have 3 monitors.  When running Published
Applications, we find that 2 of the monitors work but the third does not.
You cannot drag a Published Application into the third monitor.  The first 2
monitors are fine but the third is ignored.  The monitor config is as
follows:

19" Monitor (1440 x 900 x 32)
19" Monitor (1440 x 900 x 32)
17" Monitor (1280 x 1024 x 32)

We have not changed the default ICA Display memory allocation.  Farm setting
"Maximum memory to use for each session's graphics" is set to 
5625 kilobytes.  

Im not sure if the ICA session is running out of memory.  Where can I see
the session memory usage?  Based on articles Ive seen, you can determine the
memory requirements by:

1440 x 900 x 4 = 5184000
1440 x 900 x 4 = 5184000
1280 x 1024 x 4 =  5242880

Based on this calculation these sessions would require 14Mb.  Am on the
right track with this?  Im currently running Citrix Presentation Server 4 on
Windows 2003.  ICA Web Client version is 10.150.  Can anyone suggest any
other changes apart from upping the graphics memory to 14Mb in trying to
resolve this issue where I cannot drag to the third screen?

Thanks
Ang
