I have a kvm guest instance of Ubuntu 14.04 running with a vga
type video device. I do not have a /etc/X11/xorg.conf
file, I am letting X autoconfigure the video and all devices. When X comes up, the screen resolution is only 800x600. The expected resolution is 1280x768.
I used to get the correct resolution before upgrading to 14.04. The 14.04 guest image was originally cloned from a 13.10 kvm guest instance. When I boot the 13.10 guest now, I still get the correct 1280x768 resolution.
It seems like something has changed for the worse between 13.10 and 14.04, any ideas if this is expected (do I now need xorg.conf
?) or should be reported as a bug?
