Photon GUI alone to replace X windows would be amazing.
- Animats 8y agoI used it as my main desktop system for three years while working on a self-driving vehicle, in 2003-2005. There were versions of Firefox, Thunderbird, and Open Office, so you had all the essentials. It's OK, but would feel dated to most users. The really great feature is that there is no lag. The consistency of QNX is impressive. This is a real-time system, not a warmed-over time sharing system. No swapping or paging. Proper CPU scheduling. So little "why did it do that?"
- sgt 8y agoTesla is using Linux and Qt UI which seems to work pretty well.
- fouc 8y agoIt was amazing to be able to restart the GUI without even impacting the apps that were running.
- zozbot123 8y ago>... No swapping or paging. ... That's more of a function of your hardware resources and workload than the OS architecture you're running. E.g. a lightweight Linux desktop installed on present-day hardware will literally run with zero swap use - in fact, it will cache most disk access. (Unless you open something that hogs RAM, of course.) That may not be literally a soft-RT system, but from the user's POV it's just as snappy as one.
- spamizbad 8y agoYou must have been throwing a lot of CPU power at it, or perhaps I've just been extremely unlucky: I've used multiple QNX based user interfaces and the one thing they all had in common was their lagginess and unresponsiveness.
