The session dies when the session manager dies. Traditionally, the window manager DID take that role but full-blown DEs (and IceWM too) work around that by having a separate session manager which launches the WM and can restart it if it dies. For LXDE, it's lxsession, as you can see from the output of the pstree command. (Or by experimenting. Kill openbox and the session stays open. Kill lxsession and you find yourself back at the display manager login prompt.) > Well, anyway, I still believe any autorestart is a workaround, which > is dirty and very bad thing to do, we have to fix core components instead > of workarounding bugs. :) And having a backup parachute when you go skydiving is an ugly hack. I like my desktop to have defense in depth rather than assuming that fallible humans can write infallible code. (Even then, I still set all my applications to auto-save as frequently as they allow... or every 60 seconds if they impose no lower bound.) I'll take practicality over elegance in my desktop's core components any day. In fact, that's one of the reasons I never run a composited desktop, even with something relatively light and effect-free. Far too often, when the compositor crashes, the system console is stuck displaying the now-frozen redirected surface until you boot another PC, SSH in, and restart the compositor. > > Well, how Xfce, GNOME, KDE, etc. handle similar issues?

Given how often Plasma and Kwin crashed last time I tried them (around KDE 4.5), KDE would be unusable without auto-restart in the session manager. I hear Kwin has stabilized but, according to one commenter on Phoronix, Plasma got horribly unstable when they rewrote it using QML and there are still enough bugs in it that the auto-restart is getting a workout. (The commenter was complaining about how they're working on KDE 5 without bothering to release a stable KDE 4 first.) It's been ages since I tried GNOME but I remember GNOME 2.x auto-restarting something (either `nautilus --desktop` or gnome-panel) when it crashed. As for Xfce, I only use it on my OpenPandora handheld (it's the default desktop in the official firmware) but something about how the Alt+LeftClick dragging interacts with the touchscreen causes xfwm4 to crash often enough that I can assure you, it does auto-restart core components. > About PCManFM I treat any crash as issue that should be fixed ASAP, > and that issue should never ever happen and I highly suggest never do > autorestart on it.

It would be unusable for people like my mother if the auto-restart didn't restore the desktop icons after a crash. Every other desktop auto-restarts core components and LXSession currently does too. It's the only sane option: Strive for the best, plan for the worst. (Work hard to ensure there are no crashers in each component but design the rest of the system around the assumption that crashes will happen frequently.) ------------------------------------------------------------------------------ November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
