VirtualBox changing graphics mode flickers screen on dual head

Description (last modified by aeichner) (diff)

Ubuntu 8.10 with an ATI Radeon graphics card with two monitors, using proprietary driver shipped with Ubuntu.

Whenever a graphics mode switch occurs (e.g. from Bios screen to text mode Windows startup status bar, or changing the desktop resolution in Windows), the second (right) monitor blackens for about two seconds and then reappears.

Further questions welcome. Thank you for working on VirtualBox!

Note: To clarify, whenever a graphics mode switch in the *guest* system occurs, the right monitor on the *host* system flickers. Confirmed for XP and Vista guests on said Ubuntu Intrepid host.

Try if starting a VM manually with

VirtualBox -startvm VM_NAME -rmode image

makes any difference for you.

Cool! When starting from the command line, the flickering does not occur. Thanks a lot for the workaround!

Multi-monitor is now supported since VBox 3.2.x.

Please retry with 3.2.6.
