I'm running the Stockmind 17.10 Ubuntu distribution. In that my desktop of choice is TDE (https://www.trinitydesktop.org/) and from time to time I get it running well on the GPD Pocket. But then after a logout or reboot, the fonts, window furniture, etc., goes all to hell, all weird sizes, etc. I've run

xdpyinfo | -B2 resolution

and gotten

dimensions: 1920x1200 pixels (96x60 millimeters)
resolution: 508x508 dots per inch

which is of course wrong, and indeed one of the X configuration files has the correct information.

Is there something peculiar being dome by the GPD machine that causes it to behave thusly? I've gotten KDE/TDE to run just fine on a world of other computers. This is a first and I'm having a terrible time trying to sort it. What config files does X actually read?

Where is scaling for things not GTK set?
