I am running a gentoo guest OS on qemu-kvm. I can only get resolution of 800x600 in it. I want to be able to get a higher screen resolution.
xrandr gives the following output :
xrandr: Failed too get size of gamma for output default
Screen 0: mimimum 640x480, current 800x600, maximum 800x600
Xorg -configure fails with segmentation fault :
open /dev/fb0: No such file or directory
Segmentation fault at address (nil)
I am using default vga settings for qemu and lspci shows :
VGA compatible controller: Cirrus Logic GD 5446
So my question is:
what is this frame buffer ? Is it required to do Xorg -configure?
Is there any other way to increase screen resolution ?
