Hello Qubes forum! I just released a brand new XFCE Win 10 look-alike theme and I'm pleased to announce that I've just added dedicated Qubes OS support for it! Example screenshot below (new forum users can only embed one picture, check the download link for more!): qubes|690x387, 100%

You can choose between 3 different window border options for Qubes: Standard (no coloring), Colored 1 (colors windows when focused), and Colored 2 (colors when unfocused too)

You can find the theme here. The instructions to set it up (which are mostly copy pasted from the guide txt file) are below. It's currently dark mode only, but I'll probably get started on a light version soon.

QUBES OS SETUP GUIDE (4.3) ---Dom0--- Populate and run the following command in Dom0 to copy the theme to Dom0 [DISCOURAGED BY QUBES DEVS FOR OBVIOUS REASONS]

qvm-run --pass-io <source-vm-name> "cat ~/Downloads/Fake10-v2.tar.gz" > ~/Desktop/Fake10.tar.gz

Extract the theme by running "tar -xvsf ~/Desktop/Fake10.tar.gz" Modify the following CSS by running "nano ~/Desktop/Fake10/Theme/Fake10/gtk-3.0/gtk.css"

.xfce4-panel .tasklist button box image {
    background-color: red;
    margin-left: 5px; <----- [CHANGE TO 9PX]
}
.xfce4-panel .tasklist button:checked box image,
.xfce4-panel .tasklist button:hover box image {
    margin-left: 9px; <----- [CHANGE TO 13PX]
}

This fixes the taskbar program icon alignment for XFCE 4.18 (currently what Dom0 is using) since they render smaller than on 4.20 it seems like. Could also just be Qubes.

Delete the following lines of CSS

#whiskermenu-window > frame > stack > grid > box > stack.contents > grid > scrolledwindow > viewport.frame {
    margin-right: -3px; /* fix offset from scrollbar */
}
#whiskermenu-window .categories {
    margin-left: -3px; /* fix offset from scrollbar */
}

This fixes start menu category button alignment with the persistent scroll bars. Since Qubes has a ton of categories, not all are visible at once usually, which changes the behavior.

Install Fake10 like normal (guide below) Copy the window borders from ~/Desktop/Fake10/Qubes/Themes/ to ~/.themes/ and apply one in Window Manager Hide the Whonix sdwdate icon by going to the Status Tray Plugin settings Reboot system to fix icons, cursors, fonts, scrollbars, and alignment ---Other VMs--- Install the UNMODIFIED Fake10 theme in the rest of the VMs (setting accent colors is recommended) (again, guide below) In sys-net specifically, overwrite some icons in ~/.icons/Fake10/16/ with the ones from ./Qubes/Icons/
