Hello TDE Developers,
I am not a TDE developer, but if you are willing to hear from random people on this olist...
I recently purchased a Dell XPS15 laptop for my daughter and before I turn it over to her, I am experimenting to see what must be done to make it usable under Linux/TDE for those with no better than normal eyesight. Per EDID, the laptop's native screen resolution is 3840 x 2160 and its physical screen dimensions are 346 x 194mm (~15.6" diagonal). My objective is to run the laptop at native resolution both inside and outside of X (no re-scaling).
I am using a macbook pro (2880x1800 on a 15" screen) and a 4K 27" monitor, and I went through this a while back.
Having said that, while I use various TDE programs, I don't use TDE's window manager, so this advice may not work for you.

Of course, if HiDPI issues have already been addressed by others in the post R14.0.4 source code, that would be great.
I solved a lot of problems by putting
export GDK_SCALE=2in my ~/.xprofile, which gets read by /etc/X11/xdm/Xsession, /etc/tde/tdm/Xsession and /etc/kde/kdm/Xsession (at least on my system) and helps a lot of GTK3 programs look reasonable.
It shouldn't hurt (too much) to give this a try. I'd be interested in knowing how it works out.
It is too bad that so many software designers assume that screen resolutions would be 90 - 100 DPI for all time.
Cheers.
Jim

Hi Jim,
I think the Firefox I am using was built to utilize GTK+-3.x. If that is correct, I did not see any issues with it despite the fact that the GDK_SCALE environment variable is not set.
I am curious about one thing you mentioned: are actually using TDE (the desktop environment per se) with a window manager other than twin? If so, I would be interested to know how that worked out for you as I had noted that alternative window managers can be configured. That might solve at least the "microscopic window resizing arrows" part of the problem.
Thanks, Vince
