- have you actually run updates and upgrades since you installed the Fedora 36 KDE?
If not, you should do so in one of two ways -
- Click on the orange button (bottom right of your desktop in the System Tray) for Dnfdragora and choose update, or
- From the Terminal (Konsole in KDE) run
As a part of that exercise, it will update your KDE Plasma desktop environment from the installed v5.24.3 to v5.26.4-1.
Presuming that you are running on the default Wayland Display Server, that will then bring you into the range described by @digitaltrails
above, where he says
It looks like KDE Plasma 5.26+ may have addressed the issue of blurry xwayland-apps:
and then you could try some of the other suggestions, such as he and my friend Maarten @f33dm3bits
EXT4 - the default for most Linux Distros
BTRFS - aka "Butter FS" or "Better FS" - newer, but not yet widely adopted
X11- provided by our friends at X.org Foundation
Wayland - newer, but not yet widely adopted, although Ubuntu defaults to it now.
If you simply followed the defaults for Fedora 36 installation, you will likely be on BTRFS and Wayland. Which scheme you are on can determine what methods will enhance your viewing improvement, with choices made, and also with means to put in place a Recovery Plan.
If you want to check which Display Server you are using, go to Konsole and enter the following command
It will output either
If you want to check which File System you are using, go to Konsole and enter the following command, first letter is an l for "Larry"
It will include output showing either
That being said, I believe you may be able to get the effect you are looking for by simply logging into an x11 session, as Maarten has described at #6 but the other way around - go for x11 over Wayland if you are on Wayland.
The DPI (dot per inch) figures correspond as follows, defaulting to 96 and then increments of 24.
96 dpi (usual default most Distros) is 100 % scaling or 1.0 view
Use multiples or fractions for different percentages eg
120 dpi for 125%
144 dpi for 150%
168 dpi for 175%
192 dpi for 200%
I use 144 for my personal use, and what I was able to achieve on a Fedora 36 KDE USB stick session shows in the following screenshots (click the pictures to enlarge).
SCREENSHOT 1 - Default (96 dpi) settings, in Firefox session
SCREENSHOT 2 - 150% (144 dpi) settings, back in Firefox session
SCREENSHOT 3 - 150% (144 dpi) settings, back in Firefox session, with larger White cursor
This was all done with no need to modify my Display (monitor/screen) settings which are set on this laptop to 1920x1080 (16:9).
And no need for an xrandr script at this point.
See what you think and let us know, and I achieved the larger cursor from the same area of System Settings as that for the fonts and object/icons.
