Title:
  chromium on Jetson Orin fails to open file dialog

Status in chromium-browser package in Ubuntu:
  New
Status in xdg-desktop-portal-gnome package in Ubuntu:
  Unknown

Bug description:
  For chromium 138.0.7204.157 Rev 3205 latest/stable snap
  running on Jetson Orin (arm64) with 5.15.136-tegra kernel from Nvidia.

  with snapd 2.70, it seems I must downgrade snapd to 2.68.5 (Rev 24724), otherwise browser doesn't start.
  I found recent discussion on NVidia forum:

  https://jetsonhacks.com/2025/07/12/why-chromium-suddenly-broke-on-
  jetson-orin-and-how-to-bring-it-back/

  This seems to indicate snapd has issues if kernel doesn't enable
  CONFIG_SQUASHFS_XATTR=y and apparmor, which the NVidia provided kernel
  doesn't have.

  If I do use 2.68.5, I see additional problem that file open dialog doesn't open in React applications. It is implemented with label that uses htmlFor attribute and a button and input tag inside the label, where htmlFor attribute refers to a input tag that accepts file names for .txt files. This is the primary problem here. This was earlier working, so I'm surprised it broke.
  When I try to use it, I see following logging in syslog, which seems to indicate reason for the failure:

  ```
  Jul 24 10:39:34 ubuntu xdg-desktop-por[19354]: Backend call failed: Message recipient disconnected from message bus without replying
  Jul 24 10:39:34 ubuntu chromium_chromium.desktop[39413]: [39413:39413:0724/103934.435160:ERROR:components/dbus/xdg/request.cc:169] Request ended (non-user cancelled).
  Jul 24 10:39:34 ubuntu systemd[19053]: xdg-desktop-portal-gnome.service: Main process exited, code=killed, status=11/SEGV
  Jul 24 10:39:34 ubuntu systemd[19053]: xdg-desktop-portal-gnome.service: Failed with result 'signal'.
  Jul 24 10:39:34 ubuntu systemd[19053]: xdg-desktop-portal-gnome.service: Consumed 1.239s CPU time.
  ```

  I have also seen following messages in syslog (from earlier attempt):

  ```
  Jul 22 16:02:40 ubuntu systemd[651658]: Starting Portal service (GNOME implementation)...
  Jul 22 16:02:41 ubuntu xdg-desktop-portal-gnome[710339]: libEGL warning: DRI3: Screen seems not DRI3 capable
  Jul 22 16:02:41 ubuntu xdg-desktop-portal-gnome[710339]: libEGL warning: DRI2: failed to authenticate
  Jul 22 16:02:41 ubuntu dbus-daemon[651675]: [session uid=1000 pid=651675] Successfully activated service 'org.freedesktop.impl.portal.desktop.gnome'
  Jul 22 16:02:41 ubuntu systemd[651658]: Started Portal service (GNOME implementation).
  Jul 22 16:02:42 ubuntu xdg-desktop-por[651957]: Backend call failed: Message recipient disconnected from message bus without replying
  ```

  So it looks chromium is triggering request to xdg-desktop-portal-
  gnome.service, which crashes, and this is somehow related to DRI3 or
  DRI2 authentication. OTOH, xdpyinfo says the X server supports DRI2
  and DRI3.

  This does not look like a web application problem because when I
  connect to same application from a Windows machine's chromium browser,
  the functionality works.
