Description Kevin Verma 2008-08-22 10:28:22 UTC

Description of feature: 

Currently graphical console displays GuestOS is all available colors. This turns to be a productivity issue while accessing GuestOS remotely (on low bandwidth)

It looks to be desirable to configure graphical console to switch to low color modes. 

Current workaround is to configure VNC or similar remote desktop solutions and use client apps to switch to low color mode. Not suitable work around for situations where administrator is remotely located all time.

As far as I know, this isn't supported at the gtk-vnc level, so reassigning there. Once that is complete, it would be pretty easy for us to support it in virt-manager.

Comment 2 Daniel Berrangé 2009-12-13 17:49:42 UTC

Moving back to virt-manager, since this capabilities is present in gtk-vnc-0.3.10-1.fc12.i686.

*Before*  calling vnc_display_open(), you can call  vnc_display_set_depth() giving one of the constants

        VNC_DISPLAY_DEPTH_COLOR_DEFAULT = 0,
        VNC_DISPLAY_DEPTH_COLOR_FULL,
        VNC_DISPLAY_DEPTH_COLOR_MEDIUM,
        VNC_DISPLAY_DEPTH_COLOR_LOW,
        VNC_DISPLAY_DEPTH_COLOR_ULTRA_LOW


Default, uses whatever the server decides is its preferred. The other 4 correspond to forcing use of 32bpp, 16bpp, 8bpp, and 4bpp. Recommend leaving on the default setting unless explicitly needing an alternative.

Comment 3 Cole Robinson 2010-03-01 02:04:05 UTC

Moving to the upstream virt-manager tracker.

Comment 5 Cole Robinson 2014-02-01 00:53:40 UTC

Since spice exists nowadays, which has all sorts of smarts about limiting bandwidth, and which doesn't even support low color modes AFAICT.

If someone turned up tomorrow with a patch, I'd help it get in. But virt-manager devs are unlikely to ever implement this. So closing as WONTFIX
