Input Devices keeps disconnecting and reconnecting #149

Closed medanimohamedakram closed 3 months ago

medanimohamedakram commented 4 months ago

when I upgraded to 4.2.0 Mouse and keyboard kept lagging and I noticed the numlock and Caps kept flashing as if connecting and disconnecting continously I downgraded to 4.1.3 and every turned back to normal

I tried building from source to the latest commit but the issue still persist

Thanks for reporting! Was it possibly caused by a still running, not updated keymapperd instance being incompatible with the updated keymapper instance? Or the other way round. Could you stop both before installing the new version? (sudo systemctl stop keymapperd, killall keymapper) I will add a version check, which should detect this problem and exit with an error message. If that was not the cause, could you please start them manually with the verbose flag and post the output. (sudo keymapperd -v, keymapper -v). Thanks!

I had a similar issue after upgrade which got fixed by restarting keymapperd. This check sounds like a good idea. I don't know if this would be feasible, but I think even better would be if keymapperd would be forced to restart after an upgrade. I realise this is not how upgrades are normally handled on Linux, but I could see this as an exception due to the tight coupling between the processes.

...after a bit of thinking, that would be a very bad idea as the upgrades could have breaking changes 😅. A warning is much better.

I tried this and it seems that was the issue So keymapper works fine now, Thanks
