VB guest window no longer resizes on virtual display mode change => Fixed in SVN

[dimitris]

Host is Debian sid, guest is CentOS 5.2 with 2.1.0 guest additions installed, both x386.

Steps:

• Start the guest.
• Boot sequence switches the virtual display to graphical mode.
• VB window doesn't resize, instead it displays the CentOS graphical boot screen cropped to the size the VB window had originally.
• Boot sequence now starts X, same cropping present.
• Machine->Adjust Window Size has no effect.
• Resizing the VB window manually through the host WM decorations also has no effect.
• I can "force" the VB window to resize by selecting Machine->Close..., then canceling.

This is a regression from 2.0.6. Also, when I first booted the guest under 2.1.0, still running 2.0.6 guest additions, this problem was not present.

Just to be clear, this is not about auto-resizing, which isn't possible on this guest due to the X/RandR version it runs. This is about the VB guest window not resizing during the boot process, something that worked on different guests since 1.6.x.

Please could you attach a VBox.log file of a session when the resizing fails?

VBox.log of CentOS boot and Machine->Close... "workaround".

[dimitris]

In the attached VBox.log, the Machine->Close... menu selection which "works around" this problem happened at 00:02:42.084.

Forgot to mention that before Machine->Close... I tried Machine->Adjust Window Size, but nothing changed in the VM window and no entries showed up in the log (tail -f).

Thanks for this report. In the meantime we were able to reproduce this problem and we think we fixed it. This problem does not occur with every Linux guest, therefore this bug was not recognized during the final testing. And no, installing the old additions wouldn't help fixing that bug.
