Package: libqtgui4
Version: 4:4.8.7+dfsg-5
Severity: normal
Dear Maintainer,
I'm currently having some issues with running Qt4 based applications:
I get a blank window when "su-ing" into another user and trying to
run various Qt based applications from there. This happens for
mumble, keepassx or electurm for me, for instance.
GTK based applications like eog, libreoffice, iceweasel or gedit run
fine from this alternative user.
Usually I grant display access rights to the alternative user via
"xhost +local:linus". However "sudo gksu -u linus mumble", too, just
gives me blank windows.
The X server runs within a VNC session, started by Xtightvnc. The
window manager within that X server is Xmonad.
Running Qt4 based applications via ssh X forwarding instead of VNC
works fine though. At least after granting the user "linus" read/write
access to ~/.Xauthority of the user that started
lightdm/Xtightvnc/Xmonad/... and setting a symlink from
/home/linus/.Xauthority to /home/$x-server-owner/.Xauthority.
Cheers, Linus

Version: 4:4.8.7+dfsg-20+rm
src:qt4-x11 was last released with Debian 10 (buster)
in July 2019 and has been removed from the Debian archive afterwards.
It has been superseded by newer versions.
See https://bugs.debian.org/953294 for details on the removal.
After regular security support for buster ended in August 2022 and LTS
support ended in June 2024, I'm closing the remaining bug reports now.
Andreas
