Hi, I just installed Trinity R14.0.5 [1] in a recently installed Arch Linux based system and I'm not able to start the DM. I added 'exec starttde' line to .xinitrc and made the needed changes in my PATH variable, but, when I issue startx command, TDE won't open. Instead, the following message is shown: ----------- There was an error setting up inter-process communications for TDE. The message returned by the system was: Could not read network connection list. /home/username/.DCOPserver_hostname__0 Please check that the "dcopserver program is running! ---------- When I click 'OK', the TDE's splash screen appears, but the first icon keeps flash infinitely and the above mentioned message appears again underneath them. When I click on splash screen, it disappears and when I click in OK again, X exits to tty. The following video shows exactly what occurs: https://streamable.com/mlqy3 This is the output from starttde command: $ starttde [starttde] Starting starttde.

I have an old installation of Arch Linux in a virtual machine where Trinity works perfectly. So, I decided to play around with it and do some tests. That system was a little outdated. Thus I decided to do a pacman -Syu in order to update the system's packages. After updating, I no more could to start Trinity. It looks like that a new version from some package is breaking Trinity. Which one? I have no idea! But, I saved a list of the updated packages and also a list of packages' version before updating. Maybe some of you could try to find what package is causing the problem. Trinity works fine with the following packages' version: argon2-20171227-3 audit-2.8.5-2 btrfs-progs-5.1-1 bzip2-1.0.6-8 ca-certificates-mozilla-3.44-1 cmake-3.14.5-1 curl-7.65.1-2 dbus-1.12.14-1 dhcpcd-7.2.1-1 e2fsprogs-1.45.2-1 expat-2.2.6-1 ffmpeg-1:4.1.3-1 firefox-67.0.2-1 freetype2-2.10.0-2 gcc-8.3.0-1 gcc-libs-8.3.0-1 glib2-2.60.4-1 glibc-2.29-1 gnupg-2.2.16-1 gnutls-3.6.8-1 gpgme-1.13.0-1 grub-2:2.02-8 gtk-update-icon-cache-1:3.24.8+177+gae2ef1472c-1 gtk3-1:3.24.8+177+gae2ef1472c-1 guile-2.2.4-2 harfbuzz-2.5.1-1 iana-etc-20190531-1 iproute2-5.1.0-1 iptables-1:1.8.2-1 iso-codes-4.2-1 js60-60.7.0-1 kidletime-5.59.0-1 kwayland-5.59.0-1 kwindowsystem-5.59.0-1 lcms2-2.9-1 less-550-1 libarchive-3.3.3-1 libblockdev-2.21-1 libdrm-2.4.98-1 libice-1.0.9-2 libinput-1.13.2-1 libkscreen-5.16.0-1 libnftnl-1.1.1-1 libpciaccess-0.14-1 libqtxdg-3.3.1-3 libraw-0.19.2-1 libssh-0.8.7-1 libtool-2.4.6+42+gb88cebd5-3 libtorrent-rasterbar-1:1.1.12-1 libutil-linux-2.33.2-1 libuv-1.29.1-1 libva-2.4.1-1 libvpx-1.8.0-1 libwebp-1.0.2-1 libx11-1.6.7-1 libxi-1.7.9-2 libxt-1.1.5-2 libyaml-0.2.1-1 libzip-1.5.2-1 linux-5.1.9.arch1-1 linux-api-headers-5.0.7-1 linux-firmware-20190514.711d329-1 mesa-19.0.6-1 nano-4.2-1 nettle-3.4.1-1 nss-3.44-1 opera-60.0.3255.170-1 perl-5.30.0-2 polkit-0.116-1 proj-5.2.0-1 qt5-base-5.12.3-2 qt5-script-5.12.3-1 qt5-svg-5.12.3-1 qt5-x11extras-5.12.3-1 solid-5.59.0-1 sqlite-3.28.0-1 systemd-242.29-1 systemd-libs-242.29-1 systemd-sysvcompat-242.29-1 tzdata-2019a-1 udisks2-2.8.2-1 util-linux-2.33.2-1 wget-1.20.3-1 x265-3.0-1 xorg-fonts-encodings-1.0.4-5 xorg-server-1.20.5-1 xorg-server-common-1.20.5-1 xorg-server-devel-1.20.5-1 xorg-server-xdmx-1.20.5-1 xorg-server-xephyr-1.20.5-1 xorg-server-xnest-1.20.5-1 xorg-server-xvfb-1.20.5-1 xorg-server-xwayland-1.20.5-1 xorg-setxkbmap-1.3.1-2 xorg-xauth-1.0.10-2 xorg-xbacklight-1.2.2-1 xorg-xclock-1.0.8-1 xorg-xinput-1.6.2-2 xorg-xwininfo-1.1.4-1 xorgproto-2018.4-1 xscreensaver-5.42-1 xterm-346-1 But, if I upgrade that packages, Trinity won't start.

If at least I knew what package is causing this I could temporarily keep outdated until this problem is solved. Thanks for your attention.
