Description Stefan Bund 2004-01-30 15:31:23 UTC

Version:            (using KDE KDE 3.1.4)
Installed from:    Debian testing/unstable Packages
OS:          Linux

When trying to use krfb to share a non-local X display, the client (krdc) only receives a black screen.

Reading the source, I found, that krfb semms to use MIT-SHM *whenever* it is availible, even for
remote displays. After forcibly disabling SHM in kdenetwork/krfb/krfb/xupdatescanner.cc, remote X
displays work.

I don't know anything about lolevel X programming, so I cannot offer a patch. The only thing necessary
is to add a check for non-local displays to the if clause at xupdatescanner.cc:79

Still doesn't seem to be fixed in all cases.  This exact problem is occurring on Fedore Core 2 stock install.  Any attempt to use krfb/krdc results in a black screen on the krdc side (although a brief 8-bit picture appears).  All other functionality seems to be working fine; ie - I can move the mouse, bring up menus and start apps on the distant (krfb) end, I just can't see what I am doing on the local (krdc) side.
