4k Scaling

Hello,

I've just installed Q4os on VM to test it out and on first glance I really like it, the problem is that its unusable for me at the moment.

I got Dell XPS 15, with 4k resolution (3840x1845), and while I found the Screen Scaling option under
Control Panel -> System Administration - Screen scaling,
after changing the scaling, only the task bar looks good, but the rest of the O.S looks like this:

Is there a way to do system wide scaling  so all windows, fonts and icons will look good?

Thanks

Re: 4k Scaling

You might be able to do something with this -
Control panel > System administration > Screen scaling

Re: 4k Scaling

I have heard that 4K monitors can be a challenge with scaling.

It may be worth starting off going old school - set the scaling back to normal and then edit .xsettingsd

# Xft/DPI 98304 #set 96 dpi: 1024*96dpi=98304 here its 1024*102 my monitor is native 102 dpi
Xft/DPI 104448 

Adjust the final value according to your monitor's native dpi and put this in .xsettingsd

Then adjust .Xresources to show the correct dpi for your monitor eg Xft.dpi: 102

This is exactly what I use, the screen scales OK but the rest of the windows, the start menu and the text are not

Re: 4k Scaling

Tried it with different options, It wont work.

I really want to use this distro, but with 4k screen is impossible without proper scaling and that's a shame :-(

Re: 4k Scaling

You can enlarge the start menu manually, seize the top-right menu corner using right mouse click and drag it to whatever size you need.

Re: 4k Scaling

EDIT: Apparently, this laptop has a sh#tty monitor and is only capable to render 1366x768 correctly. The max resolution that the apu supports is for external monitors only. Don't waste your time reading below...

OK, so instead of posting a new topic I decided to pitch in with my problem here:

So, basically I want to use higher resolution for my laptop screen, which is not listed in the default config. So I went about and add it through xrandr:

viktor@q4os-desktop:~/Плот$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 16384 x 16384
eDP connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm panning 1366x768+0+0

Here we can see that the gpu supports resolutions up to 16384x16384. The one I wanted to use is 1600x900. As per the online guides, I added it using cvt, then appended it to ~/.profile:

xrandr --newmode "1600x900" 118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync
xrandr --addmode eDP "1600x900"

So far, so good. The resolution is added in Control Panel->Peripherals->Monitor...

Problem is, that whenever I switch to that resolution, the screen goes off-monitor... Let's see how to explain this... The right and bottom edge of the desktop is "hidden" outside the matrix, the desktop is streched, but it doesn't "pan" to the monitor, so half the desktop is outside the monitor and the taskbar and start button are somewhere "down below", like the screen has been only zoomed and rest of it cannot be seen. I tried with Screen Scaling and with commands to xrandr, but the problem persists. It only scales the fonts they get smaller or bigger like the windows, but the screen is still not "panned" and is outside the montior. How do I fix this?

Re: 4k Scaling

FWIW, I used a similar solution on an old Samsung Q1 UMPC that was only capable of doing 800x480 on the native monitor... there was some utility whose name I don't remember anymore that would enlarge the screen to higher resolutions, allowing one to either zoom it or scroll around (believe it or not, this was quite handy).
