This seems to be a general issue with the cirrus driver in the kernel. I found the following post in the qemu forum, which provides an xorg.conf for a 1200x900 resolution: http://qemu-forum.ipi.fi/viewtopic.php?f=10&t=4631
Regrettably I did not manage to get any higher. Using '-vga std' is no help either, because the ubuntu guest hangs on boot when trying this option. -- limited screen resolution https://bugs.launchpad.net/bugs/349331 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
