Getting closer. I went back to look at the udev rules file you package with the Redhat 5.6 RPMs. I saw that, if system is being used, you run brltty@[devname].service which, obviously, doesn't work if I don't have the fancier system unit files. So, I changed it to just run brltty.service but left the rest of your RPM-based udev rules in tact. When I plugged in the display, brltty started and stayed running!
Half way there. When I unplugged the display, no attempt was made to stop brltty. So, when I reconnected the display, nothing happened. Of course, if brltty 5.2 was re-detecting and reconnecting to a display, it would have worked, but if that was happening, I'd just ben running brltty as a service at boot and not bothering with this. :) Your brltty_systemd section of the udev rules sends processing to brltty_end if the action isn't add. So, am I correct that, when system is present, your udev rules start brltty for the connected display but don't stop it? And, in this case, the probing from inside brltty is used to reconnect? If so, I think I'm back to building 5.6 from source. I'm toying with this idea, since I have no experience with building ebuilds, of building rpms and using Gentoo's limited rpm support.

I didn't know udevadm, but that's a good one to know. I already knew how to get system to reload its components from disk; in this case, I hadn't changed any of those, but I did it, anyway, for good measure. Sadly, even after a udevadm control --reload after renaming the brltty rules to get them out of the way (I even moved them completely out of /lib/udev/rules.d to be certain it wasn't reading them with my .old extension, even though I know udev doesn't do that), brltty still fails to redetect the display after I reconnect it. I've got it running with a systemctl start brltty. And I know last night with the brltty-wrapper for udev in place, it was re-reading the rules file and calling the wrapper based on systemctl status system-udevd. But as I said, it was still killing it after 3 minutes. I'll tinker with the udev bit a little more, but running brltty as a service would definitely be simpler if I can get that working instead. Do you think the reconnect issues with brltty running as a service could be my older version of brltty? Since I'm still on 5.2, and as I recall you did some major work on reconnects around 5.5, might I benefit from being on the latest version? It might mean building from source, but I'll do that if needed. It's not that painful.

Okay, so what I said about RecHat maybe wanting to manage brltty their own way may well have been wrong. Thanks for the clarification. As for your probems(s), yes, you do need to tell udev when its rules have been chagned and systemd when its units have been changed. For udev: udevadm control --reload For systemd: systemctl daemon-reload The make files for the latest brltty in Autostart/Systemd/ and Autostart/Udev/ both support "make reload". Neither of these commands stops anything. For systemd, you should systemctl stop, then modify the units, then systemctl daemon-reload, then systemcl start. For udev, you'll need to exlicitly kill whatever you want to first stop. It isn't clear to me how you modified the udev rules file. Just take the one from the latest brltty. -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke | 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: [email protected] | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | _______________________________________________ This message was sent via the BRLTTY mailing list.
