Solaris 9 system over KVMs

Hello all,

I am currently trying to setup 5 old sparc systems so that they work over old Compaq ps2 KVMs. Only one of the systems is working, and the other 4 do not. The monitor frequencies are getting messed up. On the system I have them set to 1280x1024x60 res. However, I noticed one difference from the one that works and the other four. On the Sun monitor locally (not through the KVM) it shows the correct KhzH and hzV but it also shows two letters. On the one that is working it displays a PP and on the other four a NN. While on the other side of the KVM it loses about 1hzV and up to halve of the horizontal. The only other consistent difference over the systems is the one that works has a prom version and asic version lower than the other four. I have tried changing the resolution and multitude of other things but still only that one system works.

I am told that I can/must get these systems to work over the KVMs.

Any ideas?

Try bypassing the kvm, run kdmconfig get the monitor working and then copy /etc/dt/config/Xconfig or /usr/dt/config/Xconfig to a backup file, try reconfiguring with the kvm and see if there are any differences.

The Problem is the KVM. I found that the one system that works has an older video prom revision and older asic revision. The newer systems are being under sampled at the KVM level. Over all, these devices will not work together. Thank you for your help.e

I went through the Xconfig files on the system that works and the ones that do not. The are identical. Most of the feed back i get is that it must be hardware but there has to be a way to fix it. If you have any other ideas or advice please let me know.

I left out one thing thoug, i have PCs working just fine over the same KVM so it has to be somthing with the sparc systems.

We use Sun Sparc and Sun X86/X64 boxes with blackbox servswitch KVMs in our lab here and I haven't seen the issue. I do see a similar issue with an older two position KVM and an Apple powerbook. In my case the KVM is confusing the hardware's multihead detection. I don't know if that is the case with your graphics adapter. I'll post here if I hear of a workaround.

Have you tried setting the SPARC boxes to 24-bit color?This is usually changed by editing /usr/dt/config/Xservers or copying this file to /etc/dt/config/Xservers and editing this version. Add a -depth 24 to the end of the line which looks like this:

:0Local local_uid@console root /usr/X11/bin/Xserver :0 -nobanner

So it will look like this.

:0Local local_uid@console root /usr/X11/bin/Xserver :0 -nobanner -depth 24

Hello,

I tried adding the -depth 24, it could not start the display. i got the following error: The x-server can not be started on display :0....

I also tried forcing the display to 24 by useing:

fbconfig -depth \24

but i get an error saying that here is not enough memory, to force use nocheck.

I could not figure out how to get nocheck to work.

Also, the system that works has depth not set and the Xservers file matches.

Hello,This will be my last post on this topic.Over all, i had to use a Belkin KVM instead of the old HP kvm. Thank you for all of your help. I was able to get the belkin to work.
