qtfm - xcb error

[nevils1]

New install of OpenBSD 7.2 (added nano)

qtfm worked a couple of times after it was added (via pkg_add).

Now, when opened, in both root and user ...

"Warning: Could not find the Qt platform plugin "xcb" in "" ((null):0, (null))
Fatal: This application failed to start because no Qt platform plugin could be initialized."

The error output recommended re-installation. Tried that. No change.

qtfm version is 6.2.1

pkg_info | less

shows qt5-5.15.8p0, qt6-6.4.2, py3-qt5-5.15.7p1 installed.

find /usr/ Path/ -type l -ls |grep -i 'xcb' shows ... 
/usr/local/bin/python3-config.YgBcLLwTNy -> python3.10-config
/usr/local/bin/platforms -> /usr/local/lib/qt5/plugins/platforms/libqxcb.so

.Xresources file changes:
xrdb -merge $HOME/.Xresources

# set your background color
xsetroot -solid dimgray

# sadly, xclock has a bug where the font selection is ignored when UTF-8
# is enabled, so we unset LANG here.
LANG= xclock -strftime "%a %e %b %Y %H:%M" &

# disable system beep
xset b off

# start cwm!
exec cwm

Any ideas, please?

Hello, and welcome!

You state you are running 7.2, but it appears to me that you are running a -current snapshot rather than -release, as you have noted some -current packages installed. As I'm running -current on an amd64 laptop (last updated via snapshot yesterday, Feb 2), I installed qtfm to try to replicate your problem. I could not. It ran without error.

qtfm worked a couple of times after it was added (via pkg_add).

Now, when opened, in both root and user ...

Something changed between when the package was added, and when it began to fail. I cannot tell you what that is.

The maintainer for the qtfm port and the resulting package is Dr. Brian Callahan, who may be able to assist you with problem source identification if you cannot determine what has changed. His email address can be obtained from $ pkg_info qtfm.

More information can be gathered by applying the debug parameter when launching the application:

QT_DEBUG_PLUGINS=1 qtfm

I don't use Qt myself so I won't be much help directly though, sorry.

I forgot that I had run

sysupdate - s and pkg_add -uU snap

to try to fix the problem.

I'll reinstall so I know exactly what is what.

OK re. the maintainer - I'll save that info in case I need it even after a reinstall.

The problem is that you did a sysupdate to snap. So you don't have 7.2 anymore. You are now running a snapshot release of what in the future will become OpenBSD 7.3 release.

You also did a upgrade of your packages, but because package building takes some time, it is possible that your upgraded snapshot packages have been built on an slightly older snapshot version. Sometimes this works, sometimes it does not.

I would recommend to reinstall 7.2 so you can start with a clean slate

Clean install & same failure.

(Emailed the maintainer, no reply.)

Edit:
New clean install.
Allowed xenodm to handle x-windows.
pkg_add -v nano
pkd_add -v qtfm

qtfm from root worked fine.


Created new user via adduser
Added new user to staff and wheel groups in /etc/group
wheel:*:0:root,user
staff:*:20:staff,user

Edited /etc/doas.conf
permit nopass keepenv :user
permit nopass keepenv :wheel
permit nopass keepenv root as root

su user
"Error: "ksh: Cannot determine current working directory" (???)
whoami = user

qtfm
"Warning: Could not connect to the display ((null):0, (null))
Info: Could not load the Qt platform plugin "xcb" in "" even though it was found. ((null):0, (null))
Fatal: This application failed to start because no Qt platform plugin could be initialized."

su back to root
qtfm still worked fine.

su - i user
qtfm
"Warning: Could not connect to the display ((null):0, (null))
Info: Could not load the Qt platform plugin "xcb" in "" even though it was found. ((null):0, (null))
Fatal: This application failed to start because no Qt platform plugin could be initialized."

su back to root
"Warning: Could not connect to the display ((null):0, (null))
Info: Could not load the Qt platform plugin "xcb" in "" even though it was found. ((null):0, (null))
Fatal: This application failed to start because no Qt platform plugin could be initialized."

su -i for user broke qtfm for root, why?

Edit 2 This looks similar ... https://github.com/ksh93/ksh/issues/141

Edit 3: Rebuilt /etc/doas.conf using vim rather than nano. Opened then saved /etc/group via vim as well. (Based on guidance that nano can cause a rare problem.)
Logged in as user, rather than root, and qtfm worked fine. su to root and the error occurred with root. Exit back to user and qtfm works OK. Very weird ...

Edit 4: Mucked around a bit more and have things as stable as I can get them. Moving on to server setup.
