Do not let Wine to change resolution...

[etwineb]

I noticed a strange behavior when Wine changes the resolution of the screen to play some fullscreen application.

It usually works perfect, but when the application leaves the resolution is not restored. This is minor, but even xrandr -s 0 has no effects. Even the xrandr output list shows the expected resolution.

I usually start wine application via script selecting the resolution forehand, yet it is strange.
What can possibly be the problem?

[oiaohm]

etwineb there are two issues that cause the problem you are talking about.
1 is some windows applications don't restore resolution when they close. Those applications is a wrapper script around them to restore resolution is correct action. It is very hard for wine to work out when all of a particular application has end so it was decided a long time ago not to address this but to give the recommendation of wrapper script.

Think multi exe programs where the first program sets the resolution then hands off to other exes that now expect theresolution to be something.

The second you describe here.

This is minor, but even xrandr -s 0 has no effects. Even the xrandr output list shows the expected resolution.

This is not a wine error in most cases. This is video card driver failure in most cases. You will find xrandr has ceased operating completely. xrandr is never meant todo this so is a breach of spec operating this way. xrandr is always meant to show a tag on what ever is the current resolution. The common sign of xrandr failure is that you can keep on changing the resolution with xrandr and nothing happens other than xrandr changing what it is reporting.

etwineb using a script to select it in advance with a unstable xrandr it will happen to you from the script at some time as well. The fun of intermittent bugs. You think you have got away from them when all they are doing is hiding.

Not really... xrandr fails to reset the original resolution, but it still works with the other ones. I am missing something, how is possible that changing resolution works fine when I use xrandr, but not with Wine? Does Wine change resolution in another way? (Forget about setting it back at the end of the program)

The script thingy always worked, at least until now. As I mentioned in the topic title "Do not let wine change resolution"; in my system change resolution with xrandr; exec wine; change back with xrandr works well.

[oiaohm]

WINEDEBUG=+xrandr wine program.exe
shows what wine is setting.

This can be windows application stupidity combined with xrandr being slightly defective. Some Windows applications like setting resolution more than once when they see it does not match what they requested. On some video cards this results in reseting the xrandr default. Still a driver bug.

Will know more when I see a log from wine running your program with +xrandr on.

It usually works perfect, but when the application leaves the resolution is not restored.

This is a longstanding upstream bug that will probably never be fixed.

[etwineb]

My bad, re-reading my first message I noticed I expressed myself badly. I am aware that "not restoring resolution" is a known problem.

What really puzzle me was the second part, why after wine finishes I cannot just exec xrandr -s 0 to get my resolution back, but I have to restart X.
But as oiahom mentioned, it is probably not a Wine fault either. When I go home I will play around with the suggestions.

The log shows set current mode to 1920x1080, but actually it sets the resolution of 1280x720.

No idea oiaohm?

[oiaohm]

Thanks for the tap sorry I did not see you prior response.

1920x1080 60.0 + says that the default is still 1920x1080 and still should be callable by xrandr.

What we have here is some form of very strange driver failure. I cannot see exactly how wine can cause it and in fact should not cause it. You need to open up bug report with driver maker.

xrandr -s 0 should by what xrandr is reporting switch to 1920x1080

Yes the fact you cannot switch to that resultion directly is a driver side failure as well thinking its listed as available.

[etwineb]

To answer to dougmack question; I played around with a second X server and I got the confirmation something is wrong with my video drivers. The second X server works fine, but to switch between the first and the second (CTRL-ALT-F8 and CTRL-ALT-F9) has problems. Going from the second to the first works, but to switch back results in a blinking cursor as no X servers were running; this is definitely a X problem.
