You can get close enough with a ruler. For a 13.3" 16:9 display it should be about 294.4 X 165.6 for a 267.3 DPI result. http://fm.no-ip.com/PC/displays.html has a lookup table you can check against and make comparisons. 267 is clearly the highest density there listed, and the highest I've ever seen anyone discuss on a mailing list. The practical optimum can only be determined via experimentation. > I don't have such a file; attempting to produce it using > X :0 -configure > as root and with X shut down produces a segfault; it does produce a > skeleton xorg.conf.new file. evidently I'm doing this wrong That's the unfortunate typical result of upstream Xorg for compatibility reasons retaining a virtually useless and broken tool. In modern releases it's useless 99%+ of the time. Most of the time automagic just works and no xorg.conf is needed. The main problem is "most of the time" turns into hardly ever with very HiDPI displays. > perhaps this is enough for further trouble-shooting; what do I do > next? (I prefer to set up an xconfig file.) Save http://fm.no-ip.com/Share/Linux/xorg.conf-minimal-EDID-workaround to use as an /etc/X11/xorg.conf template. Create in it an uncommented DisplaySize line. Using half the values reported above that produce 96x96 /should/ produce 192x192 as a place to start your experiments: DisplaySize 423 213 # 192 DPI @ 3200x1800 If that turns out to be overkill, try half as much increase: DisplaySize 635 320 # 144 DPI @ 3200x1800 -- "The wise are known for their understanding, and pleasant words are persuasive."
