Xorg.0.log
I have 1920x1200 60 Hz monitor connected via DP-HDMI cable to Lenovo T520
laptop.
Actual results:
I have configured 1920x1200 resolution (see xrandr).
Monitor's menu shows 1920x1080 input resolution.
Screen covers 1920x1080 physical area on monitor.
Fonts are blurry, seems like virtual screen image 1920x1200 reduced to
1920x1080 (When I configure 1920x1080 mode, fonts are OK).
nVidia binary blob can set 1920x1200 resolution properly on same HW
configuration.
Informations from EDID are correct, see Xorg.0.log.
Expected results:
Physical screen resolution on monitor should be 1920x1200.
I think there is some hardcoded limitation in DRM or nouveau driver. Because
hardware is perfectly capable of running 1920x1200 via HDMI.
