It would be great if someone figured out a way to make black background the default.

Warning: Changes in /flash are permanent! You can brick your device! Don't change anything there if you are not sure what you are doing. Before you do anything there, use tar to back up all files from /flash to the CF or PCMCIA card!
In my first post i mentioned that the power up settings are stored in /flash/egServer/registry/Powerup/ i think that you can't change the powerup configuration with the GUI, but you can configure the device, save the configuration to a profile an then use telnet to copy your profile to /flash/egServer/registry/Powerup/. All profiles are stored as supdirectories of /flash/egServer/registry/

I'm sorry, i can't see anything wrong from here, it's not easy to debug stuff like this without a way to reproduce the issue. I think the Linux on the E7495B isn't the issue here, It could be a hardware issue with your E7495B or some problem with your Network or Computer(s).

Sure you can. Just save your preset as "powerup" ;)
However this doesn't seem to help for the screen capture background setting, which still seems to revert to white.
I also couldn't find a parameter for it in the registry, but maybe I just didn't look hard enough or overlooked something.

In that case that is not stored on hwclock or there is no clock backup battery... because my unit was on GPS couple days ago.

Thank you for your kind efforts :-+
No rush... after all, with all this I am refreshing my Unix know how :)
With CF use can pick up necessary data for now... and remote is in to do list.
E7495B must be capable on VXI or USBTMC commands, that may be also god solution for my future remote...
Considering from last night one other way to bring E7485B version of egclient.jar
to Ubuntu PC... by simple copy on CF card, but
path ->
on /flash/mnt/cf/
>ls -al
.
..
empty folder! (some data like screns, xls and update files are on CF for sure....
Anyone, what is right path for my CF card?

I didn't check but without a charged battery in the battery bays or PSU power it will probably forget the date/time as I doubt it has a separate backup battery.

You *did* mount the card in the E7495 before you tried to access it, didn't you?

Now that's really easy. It says it right there (I highlighted the relevant part in bold):

It seems you're using a Transcend 8GB 133x Compact Flash card. But the error messages shouldn't be there.
Is the card formatted properly (FAT32)?

Easy:
--- Code: ---# mount /dev/hdc1 /mnt
--- End code ---
If you want to access the PCMCIA flash card (or a CF card in a PCMCIA adapter) then it's /dec/hda1 instead.

Some init script stores date and time at shutdown to a file in /flash, this date will be restored at the next boot.

I'm not sure if this is a critical error, some CF/PCMCIA cards will produce errors like this one, because they don't understand all command that the kernel sends to them while initializing the card.
