Default Re: beryl black windows bug

One thing I would suggest to Nvidia, is that perhaps they should reconsider open sourcing their drivers.

I know the Intel graphics chips don't have the same horse power, but for pretty much the only thing that pushes my graphics card (using beryl with lots of windows open), Intel kicks Nvidia's ass all over the place. The advantage of open source drivers is that the more popular a piece of software, the quicker development goes on it (whatever people say about Beryl being beta, every casual Linux user I have come across uses it). I would be very surprised if this bug would have persisted for so long in an open source Nvidia driver, simply because so many developers would want it to be fixed. Eventually someone is bound to get lucky and sort it out. That said I have to admit that I know nothing about graphics driver development and for the additions to be meaningful maybe they would have to divulge too many trade secrets. I don't know.

However, I am sure that Canonical/Dell would rather have a more advance Nvidia graphics chip in their soon to be released consumer notebook/desktop models, but as things stand I would be surprised (and currently it would be a mistake) if they did.

While playing around with beryl, I often had to restart my system, because the screen was frozen, and keyboard was not working anymore. To avoid having to restart the system, I found a way to escape from the frozen X by using the acpi event of the power button to change to virtual terminal 2.

On my gentoo system I had to do following modifications:

1. edit /etc/acpi/events, so that it looks like:
...
event=.*
#action=/etc/acpi/default.sh %e
action=chvt 2
...

2. then restart the acpid daemon:
/etc/init.d/acpid restart


Now by pressing the power button, you will get to virtual terminal 2. killall X will save you some time now.

I have to ask again: does anyone know of a way to script beryl behavior?. I want to change the window manager remotely from script.
you may want to have a look into the dbus plugin. AFAIK you should be able to script it with dbus.

Or you could use dcop to send commands to KDE to do whatever you want

Open Sourcing is a very difficult decision for a big company in capitalism and even more for Nvidia cause ATI is waiting at the corner for a mistake!!
But on the other hand as you said and I totally agree with you Open drivers are the only reliable workaround for most of the problems.

Now to the subject: Today I had some free time to make a couple of tests with beryl...
After a lot of finetuning I ended up to this setup for an even better solution than the other I had previously provided:
"Texture from Pixmap" "Don't Use COW" "force AIGLX" "XGL binding" "XGL rendering"

Now a few more tips for smoother and more stable function:
In xorg.conf add these lines:
Option "TripleBuffer" "True"
Option "BackingStore" "True"
Option "DisableGLXRootClipping" "False"
Under "Screen" section
And this one:
Option "RENDER" "Enable"
Under "Extensions" section

I 'm waiting for your results!!! Tell me if the whole thing was successful for you!!

Jim

Something that I figured out just now...
With the 4 settings as I said above and if you set "Use COW" the black window comes.
But with the same 4 settings and "Don't Use COW" the black bug dissapears!!!
I managed to open 87 konsole windows really fast and smooth and none of them black!

IMPORTANT set "Don't Use COW"

Djdoo - I am running your suggested settings. Performance is about the same as before at about 16,200 FPS. I was having window problems with the previous settings using COW, not the black window but corrupted new windows--still unusable. I'm not running intense tests like you, just normal use. I'll let you know in a day or so how this works out, but it's fine for performance.

F..., just after posting this, the bug appeared again. I'm sorry:

Quote:
Could someone try this solution:
put this line into your xorg.conf device section
Option "NvAGP" "0"
I give you my full device section, so that you can compare:

Section "Device"
Identifier "Card0"
Screen 0
Driver "nvidia"
Option "NvAGP" "0"
VendorName "nVidia Corporation"
BoardName "Unknown Board"
BusID "PCI:1:0:0"
Option "Coolbits" "1"
Option "AddARGBGLXVisuals" "true"
EndSection

For me it seems like since I added this option, I do not have the black window bug any more. I can open about 90 console windows, and after that, they are getting black. But if I close them all again, i can open 90 windows again before the black bug. Now it seems not like a leak anymore to me.
PS: I'm running beryl without any performance restrictions like indirect-rendering, aiglx.... Just the pure beryl. When I disable Sync to VBlank I get about 2000 fps.

My fix was to select:

Advanced Beryl Options -> Rendering Path -> Copy

My black window problems went away after that.

Copy is a solution but performance is awful.
Use the settings I posted in page 9 and you will see the difference

Not only the xorg.conf settings but also:
"TfP" "Don't Use Cow" "force AIGLX" "XGL binding" "XGL rendering"

You need both of them!!

Whoops, my computer freezed for 15 sec after starting beryl (even amarok stopped playing).

Dmesg:
Code:
May  5 01:01:55 linux kernel: NVRM: Xid (0001:00): 13, 0000 01016100 0000008a 00000400 00000000 00000010
May  5 01:01:55 linux kernel: NVRM: Xid (0001:00): 30,  L1 -> L0
And it is doing this periodically. Do you have this problem too? What is this Xid?
