Not able to launch X.

[brian_31]

Team:

We are running xemulator on nclass server with 11.0 and we are trying to export a display from a remote server running NCR Unix? we are able to launch the window from a 10.20 box running HPVUE but not the emulator( we are still getting the basic screen but when we click on an icon we get error) the error is
Function: xvt_dwin_get_font_metrics xvt_app_create
File: ./kfont.c line: 845
my question would be..
1. Why would it work on VUE and not on xemulator on 11.0 or on CDE.
2. i found on the NCR box there is xdm running.

Any clues?
Please advice.

Thanks
Brian.

Brian: a little more info would help, I am not quite sure what the xemulator does for you.

The N-class server should be able to run X itself (CDE), indeed, it should have CDE running and waiting for incoming X-connect requests (unless you turned CDE off, but it is there from the factory or default OS load).

If you have, say, Exceed on your PC, running an X session from your N4000, is that what you are talking about as an xemulator? I'm doing that as we speak, and I often telnet to other boxes (Sun), export their displays to my exceed session, and then run an X-based utility which pops up as a window in my exceed session. I could do the same thing from a native CDE session on an HP workstation, for instance, and have the remote window open there.

I suspect that you are trying to do something else entirely, but I'm afraid it isn't clear just what it is. Do you have a graphics card in the N4000? Unusual, but supported. If you don't, you must have an X display somewhere, maybe that is the confusing part.

If you could clarify this a little, hopefully we could get you some help.

I Think it might be xfonts related problem. Please refer to the link mentioned below.

Hi:
Thanks. on the n-class we run the Citrix metaframe and we access all the apps from the PC. In this case what we do is from the PC we connect to the nclass(thru citrix) and from there we launch a script(which exports the display from a NCR box and executes an application on the remote NCR server). So this application does not run on nclass but on the remote NCR server. Instaed of a PC if i use a hp-ux workstation with vue then i am able to lauch the app successfully. I hope i am clear.

Thanks
Brian.

Brian: OK, that is clearer, but there is still one hazy part: is the HP workstation running VUE also running Citrix? Meaning, is this an apples-to-apples analysis, which all works on VUE, but the identical setup (but with CDE) doesn't work on the N4000?

If that is the case, it could be fonts, as suggested. Does CDE launch OK from a standard X-session (exceed, or whatever)? I know that networking issues can keep CDE from coming up right, it relys on networking protocols even if the monitor is local. Unplugged CAT5 cable will cause HP workstations to never come up, since CDE can't launch. Other things like a subnet mask or duplicate IP address can render CDE inoperative too, even when the network allows some connectivity.

I don't know enough about Citrix to suggest anything helpful on that side, except that Citrix has to launch an app to capture its bitmaps, etc, so the start command it uses for CDE may be wrong. If you can find that startup string (in a Citrix config file or someplace?), and run it manually to see if CDE starts up right, you could narrow this down somewhat.

Best of Luck!! --bmr

Hi Again:

Thanks. But to answer your question the HPVUE box we are not running citrix.

Thanks
Brian.

Well I've read this several times and I'm still a bit confused wrt the exact problem detail

Main differences between CDE & VUE : I'd say fonts ! it maybe worth your while configuring xfs (1) since CDE normal gripes about dt-inferface fonts being missing on remote displays.

What else ? Perhaps this is an Xserver issue : I'm sure citrix has had issues in the past wrt colors : are your workstations or PC's running all in pseudocolor ?

[brian_31]

Hi Alex:

Thanks. That may be a good point. But how do i configure xfs to match that of HPVUE?

Thanks
Brian.

[Alex Glennie]

setup xfs on the vue system : there's loads of docs detailinf this in previous forum posts : on the server or PC not running VUE you'd add it (the fontserver) to the current font path by using xset +fp tcp/:7000 : see man xset(1) or if on a pc they general have a config section for fonts add the fontservers address there ?

As to color : default Xserver = 256 pseudocolor, you may want to set your pc similarly but I'm not convinced this is the problem ....

have you spoke to citrix or the vendor of the application it maybe a more generic error ?

[brian_31]

Hi:

I just found one more difference bteween the two. On the hp-ux box i found the difference...
The message is ....
DPMS has not been enabled for this X Server.

Any thoughts on what this would be?

Thanks
Brian.

[Alex Glennie]

Display Power Management Signalling : see man DPMS ...... I don't think this will be the cause as only the hpux servers would have it enabled ...it's an Xserver xtension and can be enabled via sam ... probably dependant upon the graphics card .... have you looked in the Xserver and Pc color settings yet or spoke to thevendor of the application giving out the xvt_dwin_get_font_metrics xvt_app_create
File: ./kfont.c line: 845 errors ?
