So yes, can't imagine why anyone would actually want rounded corners everywhere myself (after all curves belong on women and cars, not in a desktop environment - lol) but each to their own of course.
I have looked at the various topics regarding removal of rounded corners, but in true geek fashion there seems to be plenty of command lines to try etc, that may or may not work. Tis one of those, spend endless hours trying to do something simple, to control the UI things.
Just seems to be a no-brainer to have a checkbox somewhere to turn them on or off.
Looking at all the "Extra Desktop Themes' touted by the Zorin OS Pro rant, it seems it is not something the devs thought about, or maybe don't care about.
So was wondering if there are any out-of-the-box solutions out there yet.
You can create a text file with that content, name it gtk.css and put it to
~/.config/gtk-3.0 and
~/.config/gtk
Press ctrl+h to show the hidden files in your file manager:
In the taskbar settings you can set the margin to 0 at tab appearance to get a normal taskbar without rounded corners.
Many windows as start menu, quick settings, popups...will still show round corners. You would have to adapt the gnome-shell.css file of your used Zorin gtk theme and search there for lines which show "border-radius" and change the values there.
Easier it is to look for another gtk theme e.g. at website gnome-look.org, which has no rounded windows.
But some gnome-apps don't respect the theme and use csd and it is really difficult to get a consistent look in all windows in the current gnome or xfce versions.
It worked for all preinstalled (apt) apps which I have tested: Nautilus, Gnome Terminal, Zorin Appearance, Settings, System monitor, Disks, Calculator, Gnome Text Editor, Brave browser, Gnome Software...
Okay, impression has round corners. Do you know a way to force a flatpak to use the custom .css files? There are only guides to force a flatpak to use a specific theme.
Edit: I managed to remove the round corners in impression:
Thanks for the feedback - I noticed those suggestions in the other threads, and in some case it works, but not in others. Other options were to replace the images for the corners, but even then it is not consistent with all windows apparently.
Would prefer not to jump through hoops to do simple things, but alas, 'that is the way of things'.
A note for the devs, why not move completely away from the lack of user control MS has unleashed over the years, where a unified UI and user options are simply not there.
I should add that this seems to have been a consistent issue with Linux Distros over the years as well, where every one of them does things slightly different, and the results in lack of uniformity - so why not change that with Zorin OS
Most people coming from other OS's, especially Windows don't want to be geeks tinkering with the UI, they want a modern UI they can control easily, and just use the PC to do actual work.
That's a problem of Gnome where many other distributions are based on. They want to remove the options to give the users freedom to customize their desktop. The gnome developers want to determine how the look is and it shall not be changed.
In gnome it doesn't help to replace pictures of the window frame - there are no pictures which define the lok of a window, just in XFCE desktop which is used in Zorin Lite.
Damn, that is a pity - this is the exact mentality users want to move away from when coming from Windows. MS has consistently been removing user control for ages.
Yes, unfortunately.
The only desktop I've seen so far where you can adjust the radius of the rounded corners (and set it to value 0) using a slider in the standard settings is the Deepin Desktop.
Otherwise, there are even more exotic desktop environments that don't have rounded windows, such as Moksha desktop or when you use no desktop environment but a window manager instead there you can setup it in the .config files of the window manager, but it is not as comfortable and difficult for Linux beginners.
Often the lightweight distributions have a desktop with no rounded window corners, you could take a look there if you like that more (LXQt ...).
