Screen totals are correctly reported. Available and Viewport show exactly the values expected for a somewhat common screen size of 2560x1440. I have to wonder how you managed to get a Konq window to open at that size on a 3200x1800 screen. Odds must be astronomical that it happened by accident. > I've commented out HorizSync and VertRefresh though I did run >> hwinfo --monitor | grep -A6 'river Inf' > > and it says "Size: 293x165 mm" That's about as close as Xorg ever gets to accurate. My calculator says a 13.3" screen should measure 294.44 by 165.62. Is that the result of using DisplaySize in xorg.conf set to manufacturer's screen size specifications? > so there's some data (or there're some data) and a couple of > incongruities. > I'll stop here and talk about the progress I alluded to earlier. > I think I have kde apps in ok shape by fooling with fonts and > setting fonts to > System Settings > 120 dpi > what doesn't work is management of LibreOffice, Firefox, the intro > display for Trinity Control Center and various apps which I think are > GTK (and then there's that grotesquely large login page). I don't see exegnu on DistroWatch, so without it installed, or more information on its web site than I've seen, I don't know if GTK3 is installed or what toolkit your LO or FF packages are built using. It looks like GTK apps are just not capable of reasonably responding to a display of such high DPI on exegnu, or maybe without being run in Gnome or Mate or other GTK DE or absent some unusual manual gtk configuration or additional package support. Your inability to find any gtk*3* packages installed is somewhat puzzling. A distro released only late last year ought to be providing at least basic GTK3 support. > I'll be installing Apache Office which I prefer but suspect it will > have the same problem as LO. > it seems to me I have to fuss with GTK. Maybe searching in OO or LO forums for HiDPI discussions would prove fruitful. Maybe we need to have a look at your xorg.conf if you're still using it. At least let's see Xorg.0.log generated by the best configuration you've come up with so far, with or without an xorg.conf. > or I may follow your advice below and alter the display mode. that's > for tomorrow or the next day. ... > I may return the laptop. Assuming running at lower than native resolution won't be acceptable to you, that sounds like a good idea, unless you have really really good young eyes and better tolerance for things tiny than the existence of this thread suggests. It seems something in some software component, or maybe more than one, is just too broken for working on a 276 physical DPI screen. Is Windows still on it?
