Displacement can only be replaced by even more displacement ( car driver/biker saying ... that's why my last bike had 1700cc on 2 cylinders ;-} )
Faster than expected I got a 4k UHD monitor as primary monitor, the wqhd as second, the old HD now as second monitor for the laptop.
After dealing with the usual luxury problems (fortunately I don't have any others) which wallpapers are still suitable for 4K (not all of them), then the reworking in detail.
(I'm a self-confessed typing lazy, so I copy&paste from my FB post :-})
I would not have thought that the change from wqhd+HD to 4kUHD+wqhd would require so much work in the small details.
If a 10pt font was still acceptable on wqhd, it's no longer possible on 4k, unless I want to unscrew my eyes after an hour and throw them away ...
Browser is the easiest, you can zoom in and out on the fly, but that's about it. That's the price of using different programmes for different purposes. Theme and style, rofi and tint2, wine (preset hardly readable even with a magnifying glass), the file managers (I use several) also cook their own soup, the funniest solution is XFE, where you can enter the DPI of the monitor...
What didn't work at all was the font adjustment at tint2 for the tooltips and yes, I used the example configuration with the #tooltips section, had zero effect on me.
I have already reduced the content of my Tint2 bar, there were taskbar, systray, calendar/clock and only 4 buttons and no other programme launchers. The tooltips were not absolutely necessary ... nor were the buttons with the corresponding programme calls, so I got rid of them ;-}
Out of pure habit I left the button (double assignment) with rofi and the xfce program launcher in (rofi is also on top in my fluxbox rootmenue) and after some moving back and forth I put the bar back on the "small" monitor, so there is nothing on the UHD anymore, or 100% for the application.
Looks like this, without applications and with wine/jpg-illuminator (drag&drop works!) on the uhd and file manager on the wqhd.
Since the "virtual monitor" is 6400x2160px, the screenshot also shows the part that is not displayed on the wqhd, since it is only 1440 high.
If you use a separate wallpaper for each monitor, this is also obvious, as the virtual part shows the image remnant from the previous wallpaper that uses both monitors.
But at least I have a monitor size on which I can display almost all menu items of the Fluxbox root menu.
Almost= only 1st and 2nd level, I have partly 3 levels (as you can see) and some are currently ONLY accessible via keyboard code.
I don't need icons, xx programm launchers in a dock or bar, I put everything in various menu items.
The more important ones can also be called up individually via keyboard codes and edited on the fly at any time.
So I don't need any free space (which I rarely have where I could use it) for the mouse on the desktop to call up the menu with a right click, I call up the corresponding menu via the keyboard.
