Dave,
Some monitors and, more often, kvm switches do not provide working
EDID data. KMS based X configurations in recent server versions no
longer allow to override the screen resolution which makes it
impossible to correctly adapt the screen resolution to the monitor
in use. This patch allows to define the fallback screen resolution
to something else than the default 1024x768.
Does video=800x600 not work for you?
No, this only sets the tty resolution; the resolution of the X server
appears to be limited to the maximum as specified at line 123 in
drivers/gpu/drm/drm_crtc_helper.c:
drm_add_modes_noedid(connector, x, y);
kernel parameter TTY resolution Max. X resolution
- 640x480 1024x768
vga=0x31b 1280x1024 1024x768
