Pr/maximum size #475

uli42 · 2017-07-03T22:42:58Z

Set the limit for maximum screen size to 32767x32767

Please test if this works with your favourite window manager.

uli42: I don't think that the fix you propose here is the right solution to the underlying problem. I am not even sure, if what you saw as a problem really is a problem, or rather the problem.

We need to discuss this further, maybe we need some screen casts, that demonstrate the problem.

@uli42: I don't really like it that we have to mess around with code in Xserver/randr/. Can't this be addressed insider the nxagent code itself?

I wonder, if this could be approached differently by looking more deeply at nxagentRandRInitSizes() (in hw/nxagent/Extensions.c) so that we allow for more screen sizes initially. (Just a guess). Also, I wonder why RRGetInfo actually gets called as we have an override function named nxagentRandRGetInfo() (also in Extensions.c).

Good question, need to investigate.

Same here... The WM_NORMAL_HINTS property should always match the current situation of the screen layout, IMHO.

Have you actually testing the above code in nxagentShadowAdaptToRatio()?

honestly, no.

For clarification about what this patch addresses: I normally connect from different clients to my long-running session. Some clients have two monitors, some have one, and also the resolutions differ. As long as the initial session start happened on the client with the biggest resolution I have no problems. But if I happen to start (not reconnect!) the session from a "smaller" client that client's resolution is the value that shows up in xrandr. Reconnecting from a "bigger" client leaves me with a session that is not extendable to the full resolution. As I am using fullscreen sessions this leaves me with some black bars of unusable screen estate with no way to do something against it.

Have pushed a new version that is less intrusive and also works if DesktopResizeMode is off

uli42 · 2017-07-12T12:34:36Z

Please review once again

sunweaver

Two more comments...

Also, while at it, shouldn't we add typical resolutions up to 8k here to nxagentRandRInitSizes() right away?

Why not MAXSHORT here instead of 32767?

Same here...

MAXSHORT ist better, agreed. We can add some more resolutions but with the new maximum size you can add any resolution on your own.

However: As long as rrxinerama is active your won't ever see those resolutions.

Yep.

Ok, then leave it as is (except using MAXSHORT) and update your PR branch.

@uli42: please rebase against latest 3.6.x branch, so I can merge.

sunweaver · 2017-08-22T17:33:50Z

@uli42: What is the status of #475? I already approved the merge, but you added more commits without comment. Was that by accident? It feels that some of the newer commits should be part of a second PR.

Please give feedback on your intention for this PR. Thanks!

uli42 · 2017-08-30T19:42:01Z

To answer your question: no, those commits where not by accident, I simply noticed that we need them in the -rrxinerama case.

This patch is working but kind of worthless. It revealed a general problem: with rrxinerama activated (which is the default) modifying screens via xrandr is not really working well due to the fact the the xinerama code will throw away what the user specified on the next move or resize of the nx window. I have not yet come up with a proper idea how to handle that. You can, however, use this code together -rrxinerama.

fixes parts of ArcticaProject#472

Set maximum size to MAXSHORT (32767). This especially helps when reconnecting to a session that had initially been started from a client with a small(er) screen. Before it was impossible to increase the maximum size of a running session beyond the screen size of the client that had initiated the session. This change, together with the previous commit, fixes ArcticaProject#472

place the maximum value directly in the resolution list.

sunweaver · 2018-07-22T14:54:50Z

@Ionic: can you take a second look at that (with my look being the first). I've stumbled over this quite often when switching sessions between machines. Esp. when switching to machines with 4k displays, the size limitation of the previous host is nasty. I'd love to get this changeset in.

uli42 · 2018-07-23T17:23:33Z

sunweaver: so you saw this limitation even with active rrxinerama?

sunweaver · 2018-11-09T15:01:57Z

sunweaver · 2019-08-27T06:49:48Z

@uli42: @Ionic: this PR #475 has become quite stale but is still an issue in real life cases. I am inclined to rebase and merge it. Thoughts? Vetos?
