beryl black windows bug

But do you still have the bug?? And also very important is XGL binding for performance!! With beryl's benchmark I got only 7fp/s less with this setup!
I think it can be a workaround for the bug until it is completely fixed.
Has anyone thought that it might be beryl's bug? The driver is the same and the
architecture too NVIDIA, when we choose force AIGLX we just fooling beryl that
works with AIGLX which it doesn't actually!
Any ideas?

When you force AIGLX in beryl, you're telling beryl to use indirect rendering, which is a different path in the driver than direct rendering.

Heey.. thank U djdoo!! I was not able to use Beryl with "force AIGLX" because of the bad performance. But with "binding XGL" (whatever this means) its working really smoothly. Still some animations and especially scrolling are not as fast as with nvidia, but its bearable until the fix is there.

After battling this issue for some time, my solution was to simply add the following to ~/.beryl-managerrc (rendering, rendering path and binding options are "Automatic"):

[beryl-settings]
...
no_gl_yield=true

Not sure if this is a solution that will work for others but it did for me. I would get the "black window" bug consistently after opening 2-3 instances of either Firefox, Thunderbird or KDevelop. The only way it I could actually view the content inside the buggy black windows would be to "resize" them to minimally small dimensions.

That said, with the above setting I've had 10 instances of Firefox (yes I know about tabs), Thunderbird with 2 compose message windows, audacious and several other GTK+/Qt-based applications open without any black windows coming up while maximized.

Some of my environment information:

• Gentoo
• beryl 0.2.1
• 128MB 6600GT
• nvidia-drivers 1.0.9755-r1

I'd be interested to receive feedback from others regarding this solution or whether it worked for them.

I'm really glad to help my friend!!
Now I tested what johnjay said about just disabling GL yield and automatic settings overall but the black bug came once again for me...

lol, i've got almost the same performance! BUT DON'T, NVidia, stop fixing this issue :P.

Disabling gl_yield doesn't help my 6600gt.

Does not help my GeForce4 either. Both of my other two cards, a 5200 and a 6200 are working fine with nVidia driver version 9755 (all settings auto) on FC7 and beryl 0.21.

Hello everybody. The new beta is there and I have the bad feeling, that it wont solve our problem. One of the "Known Problems" of this version is "Kernel virtual address space exhaustion on the X86 platform". This sounds like bad news. Actually I didn't try it, but I will this weekend. Please write your experiences here.

I have the same black window issue on my EVGA 8800GTS w/640MB after about a day's use. I tried to install the new 100.14.03 beta driver today, but it will not install correctly. I commented on that in another thread. In fact, the 8800 cards aren't listed as supported in the README file! Could be an oversight I guess, but it doesn't work on my system: Core 2 Duo E6600, 2GB DDR2 SDRAM, Kubuntu 7.04 x86_64 (kernel 2.6.20-15-generic).

The beta driver is not expected to address the 'black window bug'.

Thank you for taking time to pass on the word.

BTW, any ideas on why the new beta script won't load correctly on Kubuntu 7.04? I posted more details at http://www.nvnews.net/vbulletin/show...4&goto=newpost. Thanks!
