Og busy. Og invent fire yesterday, wheel the day before. What Og invent today?

Og know! Og show future folk how a lag-free display scalable to any resolution within limits work.


/me still has several CRTs around.

CRTs were horrible. I'm glad we got rid of those monstrosities. Spend a night staring at one and they'll kill your eyes. The scalability is pointless as well because of their crappy resolutions and bad refresh rates.

Personally I wish plasma monitors would make a comeback.

Maybe. Could it be that a caveman invented time travel?

Why would you want to change a resolution anyway? You should rather be able to configure what is the native resolution of each screen and never change that. All fullscreen programs that want a resolution change should just be rescaled to the native resolution automatically. Maybe you should be able to set whether the aspect ratio should be kept (i.e. letterboxing) or whether to stretch. But that's about it.

I believe sdl2 does this on X and I believe I have it already seen with some valve games and it just feels so nice. Finally sane fullscreen and resolution handling.

That sounds sane to me. Fullscreen apps should never ask for a larger resolution than your display is currently set to anyway, because it's likely already at the native resolution of the display. If they ask for a lower resolution, then scaling/stretching or (letter)boxing are perfectly reasonable. The user should be the only one who ever requests (and is granted) a different resolution, and ideally he shouldn't even have to do that (but we all know the ideal isn't always reality).

So you guys seem to be talking about very different things here. I was actually hoping that apps would simply ask what the resolution is, and use that.
If unable to comply with that, then letterbox it, or render to a framebuffer and stretch to fullscreen. There simply shouldn't be a way to set or request resolution (without root)

I want to be able to alt+tab out and see the normal desktop. I don't want my second monitor turned black. I don't want to have all my opened applications moved to the first monitor.. oh, and I didn't want to view the game fullscreen on monitor 1.
I always set games to run windowed, and maximize that window in my windowmanager., which always gives a much better experience.

"ASKING" for change of resolution will NOT WORK MIRACLES.

Unless display manager can not be notified that app quited, and can not restore previous settings, app that ASKED for change of resolution will F*ck Up your screen resolution same as that who did not asked for permission...

....


It's lack of reliable RESTORATION, that is problem. Its normal that app misbehave. Display manager/server/compositior/ Whole D*** OS can not assume otherwise.

Well, like i said in my post above, I think "asking" (the display server) for a resolution change (and ultimately letting the DS decide if the request is granted) is fundamentally different than clients being able to directly force the screen resolution, in that the DS request can buffer settings about the resolution before it changes for a specific app, and automatically return to those settings when that app exits. Giving the app full direct control over the resolution means there's no guarantee that things get put back if the application dies unexpectedly.

That would be bad way to handle this. Users without root password wouldn't be able to change their desktops display settings, usability would be annoying and using root privileges is bad for security.

No, you're right, that is a bad idea. I think the best solution (and something I believe has been talked about with "asking" vs "setting") is that a "request" for fullscreen means the compositor can remember the previous settings used (before the request), and automatically set things back when that process exits.
