Describe your issue

I'm running XLibre (25.1.0) on FreeBSD 15, on a pc with integrated AMD graphics. I don't use a desktop login manager, but I have Joe's Window Manager installed, and I launch it with startx. Some apps won't launch from the command line, like librewolf, but others, like XFE do. I start Librewolf as:
$ librewolf
It does not launch a window but returns a message: Segmentation fault (core dumped)
The same happens if I install and try to launch the latest firefox.
Other apps I have installed, like XFE, or Nedit will launch just fine.
If I install Xorg, and restart my system, I can launch Librewolf or Firefox without a problem.

Steps to reproduce

1. Performed a basic FreeBSD 15.0-RELEASE-p4. install on an AMD Athlon system. Added my username to the wheel group. Verified I am part of the video group. Logged in as my username.
2. $ doas pkg install xlibre xlibre-xf86-video-amdgpu xlibre-xf86-video-ati
3. Edited rc.conf to include the line kld_list="amdgpu"
4. Installed Joe's WM, then edited .xinitrc to launch it.
5. startx
6. Able to launch JWM fine.
7. Launched the default XTerm and ran the following install command:
8. $ doas pkg install librewolf
9. $ librewolf
10. It does not launch, but returns a message: Segmentation fault (core dumped)
11. Installed a couple of other apps to verify, Nedit, Dillo, XFE. They all launch just fine.
12. I then install Xorg, which uninstalls XLibre. Rebooted my system, ran startx, and from XTerm I can launch Librewolf or Firefox.

What did you expect?

I expected Librewolf or Firefox to launch.

Starts fine from xterm, but I am using nvidia.

FYI.
CPU: AMD Athlon 3000G (4)
GPU: Picasso/Raven 2 [Radeon Vega Series / Radeon Vega Mobile Series]
WM: JWM 2.4.6
All my app installs were via the pkg install command. No port make installs.
Failed to launch:

• librewolf-147.0.4
• lite-xl-2.1.4
• firefox 148.0,2
  Launched:
• Nedit 5.7_1
• Dillo 3.2.0_1
• xfe 2.1.2

Cannot reproduce on FreeBSD 15 with AMDGPU and MATE:

librewolf-147.0.4

Launches fine for me. WebGL and WebGPU work as well.

lite-xl-2.1.4

Also works well. Here are both running simultaneously:

Can you post your logs and check if there's anything suspicious in /var/log/messages?

Tseli0s,

I performed a new FreeBSD 15 p4 install today.
Thisa time, no jwm, just using the default twm.
Install type: Packages (tech preview), AutoZFS, 4g swap, Stripe type, base component install only.
After first boot:
# pkg update, pkg upgrade
# pkg install xlibre
# pkg install xlibre-xf86-video-amdgpu
# pkg install drm-kmod
Added kld_list="amdgpu" to /etc/rc.conf
Rebooted system. Logged in as my username.
$ startx (confirmed twm starts).
Note: After I exit twm, I get multiple messages:
WARNING: Device driver ttydev has set "memattr" inconsistently (drv 1 pmap 6).
# pkg install opendoas then login as my user
$ doas pkg install librewolf
$ startx
$ librewolf
After entering the command it does not launch. I get: Segmentation fault (core dumped)
I install another browser: dillo
It launches.

Update:
I installed sudo, and then finally did launch librewolf successfully with xlibre.
From my observation so far I can only put it down to sudo.

The Sudo package is not installed by default when performing a FreeBSD install.
I don't know if xlibre requires the presence of sudo or calls it at some point.
I usually use doas as my preferred superuser tool.
I then uninstalled sudo, tried to launch librewolf and it launched.
I installed firefox, and it launched as well, so it may not be related to sudo.

Anyway, I attached the messages and librewolf.core dump.

[tseli0s]

Are you running sudo startx to start your desktop?

[free-4-good]

No sudo, just:
$ startx
... to get twm running, then launch librewolf etc.

[tseli0s]

So simply installing sudo fixes the issue?

In any case, I also use doas without having sudo installed and I can't reproduce this.

[free-4-good]

It seems weird and I don't know why it behaved that way, but anyway, that was what I observed.
I appreciate you for taking the time to look into this with me @tseli0s.
I'm happy to continue using XLibre as usual.
Unless there's other questions, I'm ok if this ticket is closed.

I am not running a BSD variant, but I do run XLibre as a non-root user, and do not have sudo installed.

I do have su installed from the shadow package, not the util-linux package, but can verify that there is no method (other than unknown exploits) for X to escalate privilege without my personal involvement on each occasion.
