Seems some time, I have, sometime, a really annoying behaviour with Enlightenent (E19). It happens on Archlinux (e0.19.5.1 at the time of writting), but I think it is not related with the distribution.At the same time, it happens that new screen ... [More] detection goes wrong, so it may be due to some bad driver. I'm using Intel driver (i915).So, when it happens, the symptoms are: from the login page (I'm using lightdm, but again, not sure it plays any role), I try to log the E19 loading screen seems to want to appear, but nothing happen if I switch on tty 1, ps aux | grep enligh gives  /usr/bin/enlightenment_start and /usr/bin/enlightenment I can kill /usr/bin/enlightenment_start but the other need a kill -9 if I try  env DISPLAY=:0 enlightenment_remote -restart , the command hangs env DISPLAY=:0 xrandr gives strange "current value" for screen 0: my screen is 1600x900, and when the bug happens, I get things like "3520x994"  I get the same value on .xsession-errors, first line: zone 0x31cdfc0: 0 0   3520x994  And until now, the only solution I had to make it start again was to remove my E19 profile (~/.e) - quite frustrating.So, it happens that the problem is with "e_randr" module, the Enlightenment module in charge to manage xrandr for E. Somehow it's configuration get corrupted, and completely block any new sessions.The solution is to simply remove e_randr cache files in .e/e/config when no enlightenment process runs (so kill them before if needed): rm .e/e/config/standard/e_randr.* rm .e/e/config/default/e_randr.* The name "default" or "standard" may vary (for example, I remember that when I used to use BodhiLinux, it was bodhi or something alike). And that's all ! Hope it helps other and my future me when I'll forget how to get out of that situation. [Less]

This last weed-end, I tried to upgrade my old Bodhi Linux 2.4 based on Ubuntu 12.04 LTS to Bodhi 3.0 based on Ubuntu 14.04 LTS.At some point something goes wrong with the update of the 1500 or so packages. I'm not sure about what happenned, but I ... [More] started to see stranges errors, especially when trying to install/remove/correct package, but also in other part, for example when running some Python3 scripts.Finally, everything was looking like working, but just almost working. Google fails on me on that, and I spend quite some time this week-end trying to go to the bottom of that problem, so I let a testimonial here, if it can help other people.SymptomsSegmentation fault (core dumped) with apt-get and python3 related scriptsThis appears especially when trying to install/install -f "update-notifier-common" software, for example (sorry for the French):% sudo apt-get install -fLecture des listes de paquets... FaitConstruction de l'arbre des dépendances       Lecture des informations d'état... Fait0 mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à jour.1 partiellement installés ou enlevés.Après cette opération, 0 o d'espace disque supplémentaires seront utilisés.Paramétrage de update-notifier-common (0.154.1) ...Segmentation fault (core dumped)dpkg: error processing package update-notifier-common (--configure): le sous-processus script post-installation installé a retourné une erreur de sortie d'état 139Des erreurs ont été rencontrées pendant l'exécution : update-notifier-commonError: Timeout was reachedE: Sub-process /usr/bin/dpkg returned an error code (1)The other aspect of that problem was that any Python3 related errors lead to a stack trace like that:% python3Python 3.4.0 (default, Apr 11 2014, 13:05:11) [GCC 4.8.2] on linuxType "help", "copyright", "credits" or "license" for more information.>>> foo                                                                                                                                                                                                      Traceback (most recent call last):  File "Error: Timeout was reachedThe second main symptom was that when using apt-* tools, I was getting an error message "Error: Timeout was reached" just at the end of the process. Nonetheless, everything seemed to be correctly installed/removed/etc. Bug tracking, short versionThat led me to some bug about a timeout to short for packagekit:/usr/bin/test -e
