auto-resize guest display is greyed out

[medigeek]

Host O/S: Ubuntu hardy heron 8.04 amd64
Virtualbox: Ubuntu 8.04 64-bit package from virtualbox.org (not from the repositories)
Version: 1.6.0-30421_Ubuntu_hardy
Guest O/S: CentOS 5.1 (updated)

Problem:
1) The auto-resize guest display is greyed out
2) The fullscreen mode sticks to 800x600@32

I have restarted the guest o/s after installation several times (even shut it down and booted it back up), also tried to reinstall the linux additions .run package several times.

The mouse integration works. The display is currently at 800x600@32 (before installing vbox additions, it was 640x480)

By "The auto-resize guest display is greyed out" I mean that I can't use the autoresize function, it's disabled, although the rest of the additions seem installed ok.

Xorg 7.1 does not support xrandr 1.2 yet which is required for dynmaic resizing of the guest screen resolution. This feature requires at least Xorg server 1.3 or later (check with Xorg -version).

I am using Ubuntu 8.10 Alpha 5 which uses Xorg server 1.5.0 and I am having this issue as well.

I should also mention that I'm using VirtualBox 2.0.2 on a Hardy 64-bit host. The guest is Ubuntu Intrepid 32-bit. I will attach my vboxadd-install.log.

deejross, I assume you installed the 2.0.2 guest additions? Did they install successfully or were there any warnings during the installation? I would appreciate if you could attach the /var/log/vboxadd-install.log file to this ticket. And please post the output of X -version from your guest.

frank, my first post mentions X version 1.5.0, and my vboxadd-install.log was uploaded in my second post, but it was renamed to "vboxadd-install.2.log".

I have been doing some research and it appears that the solution is very simple. Just add the following line to the /etc/X11/xorg.conf:

Driver "vboxvideo"

And some say they also needed to add this line:

Option "UseFBDev" "false"

NOTE: I have not tried this myself yet, but I will when I get a chance. Here is the relevant link to the thread where I found this possible solution: ​UbuntuForums

my issue was fixed, how do i unsubscribe?

As you are the original reporter, I will close this ticket. deejross, if you still have problems with VBox 2.2.4 or VBox 3.0.4, please open another ticket. Thank you!
