xorg log file
INFO:
3.19.2-1-ARCH #1 SMP PREEMPT Wed Mar 18 16:21:02 CET 2015 x86_64 GNU/Linux
xf86-video-intel 2.99.917-4
mesa 10.5.2-1
xorg-server 1.17.1-4
libdrm 2.4.60-2
Basically on a vanilla configuration (I just got the laptop so no xorg.conf or
anything in xinit) the driver fails to detect the resolution and (as a result I
guess) it fails also to calculate the DPI and set's it to 96.
1) [ 818.122] (II) intel(0): Setting screen physical size to 508 x 285
It's wrong, my screen is a full HD 15.6" 345x194mm
2) [ 818.089] (==) intel(0): DPI set to (96, 96)
Which is confirmed by xdpyinfo:
xdpyinfo | grep -B2 resolution
screen #0:
dimensions: 1920x1080 pixels (508x285 millimeters)
resolution: 96x96 dots per inch
However xrandr shows eDP1 connected primary 1920x1080+0+0 (normal left inverted
right x axis y axis) 345mm x 194mm
Maybe becuase was disabled and enabled during startx? I don't know.
This cause most of the DE's display everything in miniature and basically the
laptop is unusable (otherwise you go blind).</pre>
