#290 fixed CentOS 6.8 package directory is missing "winswitch" package (maybe others) badpens

The directory is missing the "winswitch-0.12....." package.

The directory does have packages like winswitch-0.12.22-1.x86_64.rpm

Do I need to hardcode my /etc/yum.repos.d/winswitch.repo to use 6.7 instead of $releasever ?

#286 invalid question about 8bit pseudocolor support by xpra Ward Braspenning


I need 8 bit pseudocolor for some x apps who use it (don't have code of these apps to change it) to get blinking colors. But I don't get xpra working with depth = 8 bit.

When I (on a Red Hat 7.2) test 'xpra start' (v0.16.2-r11889) as root with DefaultDepth and Depth 8 in /root/.xpra/xorg.conf.d/Screen, I get following error in file ':0.log':

  File "window_bindings.pyx", line 604, in xpra.x11.bindings.window_bindings.X11WindowBindings.ensure_XComposite_support (xpra/x11/bindings/window_bindings.c:5406):
  File "window_bindings.pyx", line 426, in xpra.x11.bindings.window_bindings.X11WindowBindings.ensure_extension_support (xpra/x11/bindings/window_bindings.c:2342)
  ValueError: X11 extension Composite not available

See attachments for the necessary files.

I'm pretty sure it is a restriction in the x(dummy) server:

From source code package xorg-x11-server-Xorg, v 1.17.2, file composite/compext.c, fu CompositeExtensionInit:

  //Composite on 8bpp pseudocolor root windows appears to fail, so
  //just disable it on anything pseudocolor for safety.
          for (vis = pScreen->visuals; vis->vid != pScreen->rootVisual; vis++);
          if ((vis->class | DynamicClass) == PseudoColor)

Xvnc, on the other hand, does support 8-bit pseudocolor. My questions are:

  • Is there a way to get 8 bit pseudocolor working with xpra that i overlook?
    • And do have the 'xpra'-developers an idea of what is necessary to get the 'composite' extension working with 8 bit pseudocolor. Or better to ask this on the Xorg team?

I don't know enough of it, but if Xvnc gets 8 bit pseudolor working, the I think it should also be possible to implement this for X + Composite extension. Xvnc must also use something Composite like, no?

Thanks in advance if you have the time and effort to look into these questions.

#285 fixed connecting with ssh to winswitch server is failing. Kundan Kumar Kundan Kumar

While winswitch client is trying to connect to some other winswitch server through m_DNS. It is failing to connect through ssh. Through Direct connection it succeeds. But, opening a remote application, doesn't shows on the requesting host.

I am running latest winswitch version 0.12.21, with xpra version 0.16.1. My both host system where connection is expected, is Ubuntu 15.04. I have also seen this issue in Ubuntu 15.10.

I tried to run the winswitch_applet in debug mode. Attaching a screenshot for the same.
