Fonts size issues

[sabotage3d]

Hi,

I am having some problems with the font size in Kubuntu 17.04. After the installation all the fonts were really small especially in the terminal and I had to increase the DPI to 115 using the force DPI option in the Fonts settings. At work we have CentOS and Mate both using 101 DPI and the fonts are substantially larger. It seems that after setting the DPI Chrome and Firefox don't obey the new DPI or at least not on all pages. I tried using the scale display option but using fractional values makes some things to look fuzzy. This is how it currently looks: https://i.imgur.com/np6MTP4.png.

Some additional info:

You might try changing the system DPI rather than just the font setting. AFAIK, xorg fonts are either 75 or 100 DPI (Windows fonts are 96) and I personally find the look clearer when the DPI is square. Often, xorg will calculate a rectangular DPI. For example, mine defaults to 110x109.

Try resetting the font DPI to normal, and changing the system-wide font to whatever you want. The best way to do that would depend on your video card/driver, but easy enough to add an xrandr command to rc.local:

xrandr --DPI 115x115

Alternately, in /etc/X11/xorg.conf.d/ add a file named 40-monitor.conf and put this in it:

Section "Monitor"
    Identifier  "Monitor0"
    Option      "UseEdidDpi" "false"
    Option      "DPI" "115 x 115"
EndSection

Finally, browsers may have their own settings that over-ride xorg. You'd have to search their documentation for that.
