TwinView and Seamless mode don't play nice -> duplicate of #2720

[Alan Burlison]

Host OS: Solaris Nevada build 82
Guest OS: Windows XP SP2 + all current updates, Guest Additions installed

I have a TwinView setup with two monitors, using an Nvidia card. If I switch to seamless mode, any virtualbox windows on the second monitor disappear entirely - ones on the first monitor are fine. And if I drag a seamless-mode window so it straddles both the first and second monitors. the portion on the second monitor isn't shown.

Also, when I'm not in seamless mode, if I attempt to resize the virtualbox guest window so it straddles both monitors it won't resize any bigger than the size of an individual monitor.

+1 for TwinView Support please.

Having same problem with XP guest inside XP host.

Using version 1.6.4 and this problem still exists.

I tried increasing the video ram but this does not seem to fix the problem, any other ideas?

This issue is known and even the next version will not fix this problem, sorry. The main reason is that TwinView/Xinerama support is not fully supported by Qt3. All these problems (there are more such reports) will be fixed once the new Qt4 frontend is ready and stabilized.

Not fixed in version 3.
