I started to report a bug about this, but I couldn't recreate. :p What happened: Two days ago I upgraded Pentium D (64 bit dual core) Tumbleweed host gx620 to 20191112, which failed to upgrade TDE from 14.0.4 to 14.0.6. I used the resulting configuration to QA http://bugs.pearsoncomputing.net/show_bug.cgi?id=3027 and related openSUSE and upstream bugs over recent days. Today I logged into a TDE session and ran zypper -v dup, which brought TW from 20191112 to 20191116 and TDE from 14.0.4 to 14.0.6. Since exiting that session it has been impossible to make TDM run, or startx a TDE session. A WINDOWMANAGER=/usr/bin/icewm startx session works normally, so Xorg is working as expected. zypper ve shows no TDE-related issues. Tail of xdm status: Nov 18 15:08:47 gx620 display-manager[958]: Starting service tdm..done Nov 18 15:08:47 gx620 systemd[1]: display-manager.service: Can't open PID file /run/displaymanager.pid (yet?) after start: No such file or directory Nov 18 15:08:48 gx620 systemd[1]: Started X Display Manager. Similar error shows up in journal. WINDOWMANAGER=/opt/trinity/bin/starttde startx from vtty login also fails. A window pops up saying: Could not start tdeinit. Check your installation. No .xsession-errors is generated. Two days ago I upgraded AMD Sempron 3000+ (single core 64 bit) Tumbleweed host k8mmv to 20191112, which succeeded to upgrade TDE from 14.0.4 to 14.0.6. Today I upgraded it from 20191112 to 20191116. It still works as expected. Two days ago I upgraded Core2Duo (64 bit dual core) Tumbleweed host gx78b to 20191112, which succeeded to upgrade TDE from 14.0.4 to 14.0.6. Today I upgraded it from 20191112 to 20191116. It still works as expected. http://fm.no-ip.com/Tmp/Linux/TDE/gx620/ has logs from gx620: dmesg journal tail /var/log/tdm.log systemctl status xdm /var/log/Xorg.0.log latest .xsession-errors (from TDE session in which upgrades were performed) http://fm.no-ip.com/Tmp/Linux/TDE/gx620/newbuglogs.tgz contains all of the above. Any suggestions how to fix this? -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks! Felix Miata *** http://fm.no-ip.com/
