Black Window Bug (Solutions and the way Nvidia is handling it)

[devrandom]

the bug will be fixed soon. so everyone can shut up until the new driver is released

Improving our GLX_EXT_texture_from_pixmap implementation's handling of out-of-videomemory scenarios (this is the cause of the "black window bug" when running Compiz or Beryl composite managers)

hi devrandom, kann U tell me how old that interview was?

..nevermind, found it.. one day

[asdfasdfa]

I've always used XGL - seems to work for me for most driver versions. I wonder, what am I missing out on or what do I stand to gain without XGL?

XGL is faster but lower graphics quality and less bwb problems

[LostinSpacetime]

My experience with XGL was that it was faster but had problems with some 3D applications and video playback in fullscreen mode. Maybe I didn't try hard enough because after an update I did get a white cube and couldn't get rid of it, so I stopped trying.

I came to realize that not only beryl itself, but starting some programs such as GoogleEarth seem to accelerate the apparition of black windows.
Would there be any extra little piece of hope/precision to chew on, I mean transforming the "next few months" into "{actual number} month(s)".
Please :'(

Hi there, also I have posted another workaround, thought I haven't tested it at exhaust, it is simply as change the resolution of the monitor at runtime (the classic kb combination, ie no need to configure nothing) that seemed to work and get back the screen when that happens, but not being an exhaustive test I guess it work some times and others no.

That worked in my 8800 with 9775, now I use 100.14

Thanks for the tip, I'll give it a shot next time the bug appears and let you know about the results.
It actually sounds like a great way of avoiding logging out.

*another* possible way if you can live without beryl XD will be

* ALT+F2
* write beryl-manager -d
------ I dont know what mean "-d"
* hit 4 times the down key, 1 time right key and see your menu for memorize how to load metacity or kwin XD.

I know it is not fix beryl... but I suppose it should work instead of try to hit the correct menus in a black screen!!!!!


------------------

Actually will be interesting if some 1 know how to do the same that with the menu, but with a direct command...

Also what about: with ALT+F2??? (the following will work?? or it only blow it down!!!) (you should check it out... this are only ways that I suppose perhaps work, but havent tested the myself, they are only options that show when I try to call in a console metacity).

$ metacity --replace

ALT+F2 seems to open a "Run application" command line window.
Typing beryl-manager -d opens the menu of beryl manager and then using the arrows as indicated lead you to select an alternative window manager (for me third one down is metacity) which would disable beryl hence solve temporary the black window issue. I guess at that point you can try to change the resolution which would flush the videocard memory and then resume beryl the exact same way.
Which leaves us still praying real hard for an official fix as early as possible.

This actually are work around, or let us work around , when the problem is present, just we don't want to stop working .
