Public bug reported:
I have a new Intel DZ77BH-55K motherboard with an i5-2400 processor with
on-chip HD graphics. The motherboard has one HDMI and one DisplayPort
output. For testing reasons and on the search to solve the problem I
have connected both outputs to my EIZO EV2333W 23-inch 1920x1080 (16:9)
monitor (HDMI to DVI via adapter, DisplayPort to DisplayPort), but I
have the same problem when the DisplayPort cable is not connected.
The problem is that if the computer boots up and shows the login screen
the login screen appears with 1024x768 resolution and not with the
monitor's native 1920x1080. The driver is actually the intel driver (no
fallback to VESA). After login I can correct thedisplay to 1920x1080
with the "Displays" section of the System Settings and this persists
when I log out an log in again, only the login screen and the desktop of
every new user stays 1024x768.
The problem seems that there are more than the two (HDMI and
DisplayPort) displays reported by the driver, according to the xrandr
output. Especially there is a "VGA1" display always considered as
connected and with max resolution of 1024x768. This seems to somehow
determine the default resolution, probably because the standard multi-
monitor mode is mirroring and due to the VGA1 ghost display also a
system with one monitor and one monitor cable is already in multi-
monitor mode.
