New subject: [arch-general] does using kms mean that you're stick to a framebuffer with specific resolution that you can't change?

the maximum resolution of my laptop is 1366x768, that's also the
framebuffer size with kms enabled. the problem is when i attach a
monitor with resolution 1920x1080 to it, the video output is at the
top-left corner of the monitor. and i found myself unable to change
the framebuffer size, appending video= option to the kernel command
line doesn't take any effect. so, i wonder is there anyway to get a
framebuffer with resolution 1920x1080 so i can benefit from the big
monitor while still with kms enabled?
kernel version : 3.10.0+
graphic card : intel hd4000
AFAIK this is not possible, as for VTs there is only one framebuffer
mirrored to all monitors. Enabling framebuffers per monitor
(fbpercrtc) would just result in the VTs using the boot monitor only.

Use X.
