Hi!
I’m testing linux terminal server.
If take screenshot on a remote machine and then look at it, it looks like this
But, if take screenshot on local computer – it look like this:
Display setting set to maximum quality. Used X11 vector graphics.
How to fix it?
Hi!
If you want to keep using the X11 vector graphics mode, you can change the codec used for compression of images to a lossless one. On the server, edit the ‘/usr/NX/etc/node.cfg’ file by adding the following line:
ProxyExtraOptions pack=16m-png
or, if you have enough bandwidth:
ProxyExtraOptions pack=rgb
As I understand, another way is switch to H264 encoding?
BTW, pack=none crashes nxnode.bin like
[ 2355.810759] traps: nxnode.bin[9475] general protection ip:7f88b46692f0 sp:726a8a7186908967 error:0 in libc-2.23.so[7f88b4634000+1c0000]
Thoughts out loud: I wonder why the program launched through ssh -X (firefox in this case) drawing more faster (scrolling, as example) than in the NoMachine with X11 vector graphics. Over 1G link.
P.S. Thanx, your solution work.
Thanks for reporting, ufm. That crash obviously has to be fixed by developers. If you had a core dump or (even better) a stack trace it would be great.
About performance, on top of a gigabit link with low latency ssh -X should run quite fast. NoMachine makes optimizations to reduce bandwidth and latency basing on the perfomance of the link, so you shouldn’t see difference on a fast, low-latency link, but with lower quality links you would see NoMachine still running quite well and ssh -X getting unusable. Thanks for reporting this, too.
