Actually, no. But it used to be necessary; without it, the UI was way
too small.

I didn't notice that since the scaling I have works well enough for me.

Got it!
My question was does
"export QT_AUTO_SCREEN_SCALE_FACTOR=true"
as opposed to
"export QT_AUTO_SCREEN_SCALE_FACTOR=1"
make any difference for you at all?
Because the "=true" does nothing for me.



Also, now that I got used to the scaling factor of 2, and after setting 
the icon size back to Normal, I'm wondering how much does LyX comply to 
the new way of setting dimensions, that is, how much of the interface is 
being painted in pixel/point units and not, e.g. by the recommendations 
at http://doc.qt.io/qt-5/highdpi.html?


For, I must say, even though the UI with the scaling of 1 is quite 
usable it feels crumpled and looks a bit ugly, while the scaling of two 
makes it somewhat oversized, but much nicer to look at:

(physical size of the screen is 295mm x 160mm)

My point is that Wayland did not read the local profile script last
time I checked. Manually exporting works, but settings in the local
profile scripts were simply ignored.

I'm on Wayland now, and see no difference from Xorg - (99% of the) user 
interface just works, no enviroment options set.
Out of curiosity, I tried "export QT_AUTO_SCREEN_SCALE_FACTOR=true", and 
it made no change. But following an example from 
http://doc.qt.io/qt-5/highdpi.html, "export 
QT_AUTO_SCREEN_SCALE_FACTOR=1" introduced a scaling factor of 2 (thus 
making everything too big). Wondering if that would be the case for you too.

I have a Lenovo X1 with HiDPI.


Me too.


LyX works fine, although I have to say
that I did not use LyX very often yet on that machine (GNOME here, but
this should not matter, and LyX compiled against Qt5). I have in my
local profile

export QT_AUTO_SCREEN_SCALE_FACTOR=true


This is in your .bash_profile or .profile?

Nikos



to get the proper scaling.

Hi Richard,
Fear not, LyX works fine. I'm using Gnome@Fedora on a DELL XPS 13 
HiDPI/touch. There are only a few places where widget rendering is awry, 
most notably in Document settings > Bullets. Still not sure whether this 
is because of something in LyX or adwaita-qt5 theme. In any case, things 
look much better than in 2015 
(http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg188814.html, 
http://wiki.lyx.org/uploads/Playground/)

KDE? have no idea, should be the same, or better.
And hey - whatever you find not working, we all will have someone with a 
HiDPI screen to fix it.

Go for it!


(that galago looks very much like my XPS 13 Sputnik... except for the 
thick bezel... HDD? you better go with solid state drive!)
