[directfb-users] no text and artifacts sometimes but not always

[directfb@morganleahrecords.com]

Hi,

I am having the following oddities with directfb.

Sometimes when I scroll on some webpages I get artifacts upon scrolling 
down (not scrolling up).  This never happens on freshmeat.net, or a 
handful of other sites but it does happen on google as well as any site 
that uses frames.

Now, when I first installed DirectFB and XDirectFB I would get these 
artifacts.  Then, one day--without doing ANYTHING differently and 
having made no changes to my system whatsoever--the artifacts simply 
went away.  Since then the artifacts have come back, gone away 
entirely, and now they're back again.  (I should naver have looked out 
of XDirectFB, I suppose.)

Also, I am using Qingy instead of getty and it uses DirectFB.  It works 
beautifully except no text is displayed when logging in.  The cursor 
displays fine, but no text.  As a test I compiled the DirectFB examples 
and demos and the like and none of those produced any text either.

Also, just as something interesting... A benefit to Qingy is that if I 
use XDirectFB and it hardlocks and I use ALT+SYSRQ+K to kill 
everything, when Quingy restarts the framebuffer is fine.

Compare with XFree86...when it hardlocks and if I can't kill the 
process via ssh then I'll use ALT+SYSRQ+K and it will destroy the 
framebuffer making it entirely a mess until I reboot the machine.  On 
the other hand XDirectFB hard locks typically three to five times a day.

Versions used:

DirectFB-0.9.18
DirectFB-0.9.19
DirectFB-0.9.20
XDirectFB-1.0-rc5
gcc 3.2.3
glibc-2.3.2
kernel 2.4.20, 2.4.22, 2.6-pre3

If anyone has any thoughts or knows of anything I should check.  Let me 
know if I need to provide details about any other programs or system 
configurations.

cheers,

Corey


(ps the framebuffer itself in 2.4.22 seems to be messed up... if i 
scroll to far on the console it turns to crap until it is scrolled 
several more times...doesn't happen with 2.4.20 or 2.6)
