[Bug 37072] Re: After installing (and enabling) of nvidia-glx, KDM makes wrong DRI guesses

[Luka Renko]

If your X server driver does not set DPI properly, this is due to the fact that it cannot autodetect your display size.
You can help him with setting DisplaySize in Monitor section as mentioned in https://wiki.ubuntu.com/AchimBohnet

You should also note that kde-guidance has currenly bug 40683, which prevents setting font DPI to proper size during login. See that bug report for how to workaround the bug until proper fix is released.
