I recently updated my system with a quick emerge -uDN world because I was bored and needed some excitement on my desktop, everything went smooth but when I went to restart X I noticed that one of my monitors fonts where off, thinking it was the actual application I went to check it out and noticed on my second monitor everything was fine; It hit me, it was a DPI setting, so I checked the monitor’s in question X session and noticed that it was 75×75 and not m normal 90×88 DPI. The command to check ones DPI in Linux is:
xdpyinfo | grep -B1 dot
Xdpyinfo is apart of x11-apps/xdpyinfo package if you cannot find the utility.
I had to make a settings change inside /etc/X11/xorg.conf
Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "DPI" "90 x 88" Option "metamodes" "DFP-2: 1440x900_60 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection
Adding the Option DPI 90×88 forced the monitor in question to use that DPI and everything looks good.
