Problem in Qt and Intell GPU

RezaHoss · 2025-07-11 14:39:54

My laptop has an integrated intell gpu. I use GNOME. When I run FreeCAD, which is a Qt app, I get the message below in terminal:

Fontconfig warning: using without calling FcInit()
QObject::disconnect: wildcard call disconnects from destroyed signal of QObject::139841721750336

And when I click on some buttons, the application crashes and exits, even when I use Xorg or check using OpenGL in FreeCAD's setings. I have mesa and xf86-video-intel installed. I know here is not FreeCAD forum, but my problem is about Qt and video card on archlinux.
After crashing the message below appears in terminal:

Also I installed these packages:

python-pyqt5-webengine
python-pyqt6-webengine
pyside6

What could be the problem?

Unless your intel gpu is 13 years old get rid of xf86-video-intel

So, what should I install instead?

seth · 2025-07-16 11:34:38

Nothing, you'll be running the modesetting driver on top of the i915 kernel module and likely be fine.
The current setup is broken for sure.

It is almost for 10 years old. Now should I remove xf86-video-intel?

Now I should run this?

sudo pacman -Rns xf86-video-intel

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

Says there is no such file, even when I use Xorg:

grep -e Log -e tty Xorg.0.log
grep: Xorg.0.log: No such file or directory

seth · 2025-07-18 12:33:47

Certainly not in your $HOME or random $PWD
Please read the linked paragraph, it explains where to find that file. Then post the entire file.

Generally do not blindly copypaste blue boxes into your terminal without thinking about what you're actually doing there - you'll get into trouble this way.

Most definitely remove every single xf86-video-* package you've installed.

I ran the command below, but the problem still exists!

sudo pacman -Rns xf86-video-intel xf86-video-vesa

It crashes in

#1  0x7f2c4b9f30ba in PartGui::DlgFilletEdges::onFilletStartRadiusValueChanged(Base::Quantity const&) from /app/freecad/lib/PartGui.so+0x13a

what doesn't sound overly GPU related anyway.
https://forum.freecad.org/viewtopic.php?t=97860 talks about some flatschpak and an äppimatsch - why is this not https://archlinux.org/packages/extra/x86_64/freecad/ ?
And do you get the same w/ https://aur.archlinux.org/packages/freecad-git ?

Edit:
https://github.com/FreeCAD/FreeCAD/blob … s.cpp#L928 silently asserts ui->treeview->model()

this comes from the constructor where
https://github.com/FreeCAD/FreeCAD/blob … C5-L289C35
a model is set relatively late and likely after https://github.com/FreeCAD/FreeCAD/blob … C5-L289C35 this here triggers

#5  0x7f2c9dcfd5a0 in Gui::QuantitySpinBox::updateText(Base::Quantity const&) from /app/freecad/lib/libFreeCADGui.so+0x70

Report upstream, this looks like it's merely a race condition.
