Full resolution clips bottom of guest display, taskbar

[dsmithhfx]

Hi,

I installed the VirtualBox 1.6.2 amd64 binary for Debian 4 on Debian Sid (Sidux) , and when I run a Linux guest (SliTaz) in maximum resolution for my display (1280x1024), the bottom portion of the guest display is clipped.

When I switch to full screen mode, the physical monitor display area shrinks noticeably at the top and bottom, altering the aspect ratio slightly wider. I can still blindly click the guest taskbar at the bottom to access the menu and launch apps.

When I run the guest in windowed mode, the VirtualBox window scroll bars don't work (both horizontal and vertical), and I can't access the taskbar by 'blind clicking' . The bottom of the VB window is displaced beyond the bottom edge of the host display, so I can't reach it to resize the window (for that matter, I can't resize it horizontally even though I can see the side borders, and the cursor changes over them). Ctrl-a doesn't materially affect things (except hide all window borders except the title bar).

When I run the guest at 1024x768, it displays the guest taskbar normally.

This is running from the live CD (ISO), a fresh VDI installation, and a VDI migrated from an xp host (where it functioned normally at 1280x1024 in both fullscreen and windowed modes).

I edited the host VirtualBox.xml file to allow maximum guest resolution to match my host display.

Not really sure what is going on, so I'm hoping someone else has come up with a fix for this. I haven't tried any other guests yet, or a Slitaz guest on a different Linux, VB 1.6.2 host system.

Thanks.

SliTaz uses xvesa by default (to save space on the ~25 MB distro!), but there is the option to install xorg-server. Doing this solved the problem, mostly. In full-screen mode, the bottom of the screen isn't clipped, and I have full access to and use of the taskbar. Scrolling in windowed mode is still broken, though, but that's not a biggie.
