I am using Fedora 35 under X11 on a typical 4K monitor / NVIDIA card and since there seems to be no support for fractional scaling in GNOME under X11, I have specified a screen scaling of 2 and then I modify the scaling upon a graphical login using the following script:
if [ $? -eq 0 ]
echo “X server is Wayland”
echo “X server is not Wayland”
xrandr --output DP-2 --scale 1.5x1.5
This works fine in the sense that it resizes the screen properly. However, I suspect that this scaling is software based because when the graphical environment becomes heavy, particularly when doing a Zoom with screen sharing, the performance goes down and any interaction with screen elements becomes laggy.
Under Wayland there is no such problem and fractional scaling is supported but I have other problems with Electron-based applications, including Zoom, which display empty windows without any content and I don’t think that these problems will be fixed any time soon. So, I was wondering if there is a way to achieve a 1.5 scaling on GNOME under X11 but of higher performance compared to the method I currently use.
