I can confirm the problem, using today's fully updated Jaunty + virtualbox-ose-guest-utilities 2.1.4-dfsg-1ubuntu3 in guest, so it is still a problem with the newer vboxvideo driver.
Additional info: when I run 'xrandr' in the guest, I get: m...@miki-virtualbox:~$ xrandr -q Screen 0: minimum 64 x 64, current 800 x 600, maximum 32000 x 32000 VBOX1 connected 800x600+0+0 0mm x 0mm 800x600 60.0*+ 640x480 59.9 so it seems that the supported resolution range is huge, but only those 2 modes are actually defined. -- Cannot set resolution higher than 800x600 when running Jaunty Jackalope through VirtualBox https://bugs.launchpad.net/bugs/301028 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
