>> So your X11 applications will be find.[sic]
I don't think you are getting it. I'm not worried about not being able to run my X11 applications. Well.. at least not the versions of them I am running today. I am worried about future applications and future versions of today's applications not supporting X11 and Wayland not supporting remote access.*(see next response for what I mean about remote desktop).
When I say "so what I do now" I don't mean with the exact same versions of the exact same software. I'm surely not about to go write papers in DOS Wordperfect while researching them in Spry Mosaic today!
>> That's super easy. You like VNC, RealVNC already supports Wayland. A VNC is merged into the Wayland. That full desktop experience is getting better with the RDP.
Ok, that's a good thing. Personally I use VNC today when I connect from away from home. I use an Android VNC client. I ALSO use a remote X terminal in a different room of my house from where my Desktop resides. That is not the same thing as what VNC provides!
VNC is accessed through a client program running on some other device which probably has it's own full operating system and set of installed applications. I guess you could do a barebones install of an OS and only install VNC client but it's still just going to "feel" like an application running on a multi-purpose computer. You still have to open it, log in, full screen it, etc...
An X-terminal can be a truly cut down device with little more than a kernel and X. It can be configured to connect to the server's display manager and provide a login screen. It looks and feels like you are really there. Boot time is super fast because all you are loading is a kernel plus X.
I don't see that kind of ability in VNC. With VNC you usually have to connect first via SSH, log in as the user you want to access the machine as, start the vnc server, then connect through the vnc client. Or.. you can leave a VNC session running all the time. That session is still logged in as that one user. I have tried to get a VNC server to start XDM but it didn't work. I don' t think there is any way to get to a login screen via VNC.
Check out the Linux Terminal Server Project ltsp.org. Can something like that be implemented in Wayland?
It isn't an issue of which method should Wayland implement. If it is to replace X then it needs to implement all of them!
>>>> On my X terminal there is no noticeable performance hit at all!
>>I doubt that if you are on a WAN.
Nope. I never specified that I was. I use VNC over the WAN. I use X over my LAN. I have a dedicated X terminal in my garage workshop. I very much apreciate the fact that it appears to be all the same as my main desktop but is actually completely barebones Debian plus X and very very little maintenance. Boot time is fast too, and I don't even need recent hardware.
If you still don't get how that is different from VNC then go check out the Linux Terminal Server Project at ltsp.org.
From time to time I do play with X forwarding over the internet. When I had openvpn on my router it actually wasn't too bad. I did think about giving up VNC! That router died and I haven't been able to get openvpn to work on any of my routers since. Tunneling X through ssh is pretty bad most of the time though not entirely useless in a pinch.
>> Open up some graphics remotely and start rapidly shifting the location of your terminal and over the graphics forcing redraws.
There IS more to computers than just watching videos. It would be nice I suppose to be able to do that remotely. I don't want to trade the capabilites I already have to get that though. I could also just put my video files behind a streaming server! Hell, if it was just about running today's X11 applications I could do that by just not upgrading anything at least until the last piece of compatible hardware disappears off the face of the planet.
>>>> Unless Wayland is somehow going to get us remote audio too
>>X11 already has that. Wayland has enhanced video so that gets better.
By X11 having that do you mean PulseAudio? I could never get that working. Sadly, my X terminal is currently silent. I would very much welcome a Wayland that gets me a remote login terminal that works as I described and includes audio! Making everything like VNC or Windows Remote Desktop doesn't cut it though. I want a terminal that is basically a dedicated second head to the main machine.
