I found it very difficult to get Qubes installed and useable. These are some notes I made at the time and may need some adjustment for other scenarios.

Use 8GB USB stick (left OR right side works). Bigger sizes failed for me.
disable Secure Boot
enable ACHI

edit sda2 EFI/BOOT/BOOTX64.cfg
comment out under 'qubes-verbose' section
# noexitboot=1
# mapbs=1
text install with 'inst.text' placed before i915 in the following line:
kernel=vmlinuz inst.stage2=hd:LABEL=Qubes-R4.0-x86_64 i915.alpha_support=1
make sure networking is attached to bring up GUI

I had to combine sys-net and sys-usb in the install options because I was using a docking station for ethernet.
Disable power mgmt except blank screen in Screensaver
Touchpad settings: enable tap and adjust speed

sudo qubes-dom0-update kernel-latest-qubes-vm
sudo qubes-dom0-update kernel-latest
(remove old kernel in qubes EFI)
sudo qubes-dom0-update --action=[reinstall|remove|list] kernel-latest[-qubes-vm]
sudo dnf remove qubes-template-fedora-32

A lot of video issues causing crashes. Found the following fixed it enough so far to make it useable:

change: i915.alpha_support=1 -> i915.force_probe=*

The following are some miscellaneous notes to get the DPI and GTK working right. I never tuned this properly, so you will have to play around. Please post configurations if you ever get this correct.

DPI 288 & Font size adjust to 6 in Appearance settings
Window Manager - xhdpi

  • about:config in Firefox and search for layout.css.devPixelsPerPx set this value to 2 or 1.5 as you wish to adjust the size of the Firefox icons
  • https://askubuntu.com/questions/652021/adapt-font-and-icon-sizes-to-high-definition-screen-resolutions-in-ubuntu-studio
    • 1. Set a Custom DPI setting
    • Open a terminal with CTRL+ALT+t and enter
      • LANG=c xfce4-settings-manager
    • In "Appearence"->Fonts-> "Custom DPI Setting:" set this to 288  (instead of the default 96).
    • Log off and on again to accept the new settings in all windows.
    • 2. Adapt Theme and settings
      • Set your panel size to a height of 48
      • In xfce4-settings-manager->"Settings Editor" (xfce4-settings-editor)
        • in section xfce4-desktop (create an entry if it doesn't exist)

      • gtk-large-toolbar are main toolbars
      • gtk-small-toolbar are secondary toolbars
      • gtk-menu are menus
      • gtk-dialog are dialog icons
      • gtk-button are buttons (eg the xfce panel uses buttons)
      • gtk-dnd are the icons displayed if you drag and drop a file or a folder
    • you can change them to any size as long your icon theme supports it
      • In xfce4-settings-manager->"Window Manager"
      • Download the Widepanel Appearance ** in xfce4-settings-manager->"Appearance" select Widepanel
      • In the File Manager thunar adapt the preferences:
        • Set Iconsize in the sidepanel to "small" or "normal"

xfce4-display-settings command.

Hi turscar,

thank you for your HCL report, it is now part of this pull request:


... and will be visible on the website soon!

It sounds like most of your trouble is with the integrated graphics
(Iris Xe), which is not too surprising as your laptop is very new. The
support for Tiger Lake will likely get better over time as dom0 gets a
fresher Fedora version or additional updates.

I spend months struggling with HiDPI and the solution that works best
for me is surprisingly simple:

-> remove gnome-settings-daemon from your template(s) or use minimal
templates that don't have it from the start

-> in your template add to /etc/X11/Xresources (Fedora) or
/etc/X11/Xresources/x11-common (Debian) the following line:

Xft.dpi: 288

(In dom0 leave the /etc/X11/Xresources alone and just set the DPI in the
XFCE settings)

I just saw your reply. Finally, something that works. I settled on this configuration, in case it helps anyone else. Thank you very much.

-> remove `gnome-settings-daemon` from template(s)/some dependencies removed also
-> in templates add:
/etc/X11/Xresources (Fedora/Dom0) Xft.dpi: 192
/etc/X11/Xresources/x11-common (Debian/Whonix WS+GW) Xft.dpi: 192
XFCE-settings in Appearance to DPI 192 / font 11
All Terminals ->Prefs->enable Custom Font-->set 11
Window Manager - `xhdpi` + Title font = 11
Settings Editor->xsettings->create "IconSizes" and set 'gtk-menu=32,32'

Hi turscar,

thank you for sharing your journey of qubes installation. I stumbled upon this thread, because I also have problems installing qubes and saw a possible connection to Intel Iris XE. Your system in the Qubes HCL featured the same graphic chip.
Unfortunately your approach is not reproducible for me, because two of your hints seem to not work. I try to install qubes on a HP ProBook 650 G8 with Intel Iris XE and UEFI-only.

1. Install qubes in textmode is not possible, considering this rather old (outdated?) thread. TL;DR: Text installer does not support LUKS password prompt. How did you manage to install qubes in text mode? Did you use a kickstart file?
2. You mentioned to attach networking to bring up the GUI installer. I attached a network cable, but the installer does not show any interface besides 'lo'. Did your installer recognize the network interface and why is networking important for GUI?
3. I only have a 16 GB USB memory stick but it seems to be recognized. Where did your installer fail when using a bigger memory stick?
4. I assume most of graphic related issues does not break the installer, as you did the fixes after installation. Am I correct?

My installer is starting slowly until the point where a GUI should start. After a minute of black screen, a mouse pointer (unmovable) is shown. From that point, nothing will happen anymore. Could you elaborate a little to your experience, please?

I'd be very pleased for your answers.

Kind regards
