I often confuse krdc / krfb but the server uses vnc and the client uses rdp and vnc.

[Bug 792251] Re: krdc vnc becomes extremely slow after a few seconds
Wanted to say I screwed up and miss-read the topic. I'm not connecting using VNC. I'm connecting to an XP instance using RDP. That said however, the symptoms are exactly the same as described in the original bug report. This may mean we are dealing with two different issues, however identical symptoms indicate they are the same underlying problem bubbling up into two different protocols. I am able to use Remmina for an RDP connection without experiencing this bug, so the problem seems isolated to krdc. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdenetwork in Ubuntu. https://bugs.launchpad.net/bugs/792251 Title: krdc vnc becomes extremely slow after a few seconds To manage notifications about this bug go to: https://bugs.launchpad.net/kdenetwork/+bug/792251/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

I see the same behaviour in Kubuntu 12.04 after switching over from Ubuntu 11.04 in an attempt to get away from Unity. The only additional information I can provide is that my session appears to work fine until I launch IE on the remote machine. At this point, the only workable solution is to disconnect the session, re-connect and immediately close IE. After that, the session is fine again. There may be other applications that cause this behavior but I have not stumbled upon any yet. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdenetwork in Ubuntu. https://bugs.launchpad.net/bugs/792251 Title: krdc vnc becomes extremely slow after a few seconds To manage notifications about this bug go to: https://bugs.launchpad.net/kdenetwork/+bug/792251/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
