Yes, this is important. One problem I had recently with the Via EPIA
board was that unless 2D acceleration was disabled by setting 'Option
"NoAccel"' in /etc/X11/XF86Config-4, overloading the X server would
cause interrupts from the soundcard to be completely disabled for tens
of milliseconds. Users should keep in mind that by using 2D or 3D
hardware acceleration in X, you are allowing the X server to directly
access hardware, which can have very bad results if the driver is
buggy. I am not sure the kernel can do anything about this.
Hi,
interesting that you mention the Xserver. I use a dual graphics card setup atm [Nvidia GF3
TI and some matrox pci card]. The nvidia card seems to work flawlessly even with HW
accelleration [i use nvidias evil binary only drivers]. The matrox card OTH disturbs the
soundcard severely. Whenever i have activity on my second monitor i get sound artefacts in
jack's output [no cracklling, it's rather as if the volume is set to 0 for short
moments and then back to normal]. There's a certain chance that this artefact produces
an xrun. I suppose it's because the card is on the pci bus.
I figured it's maybe an irq issue problem, but whatever slot i put the gfx card in -
it made no difference [btw: how do i find out which resources this card uses? it is not
shown by /proc/interrupts]. I also tried putting the soundcard in many different slots to
maybe get it on higher prio irq, but it always gets irq 5 [according to
/proc/interrupts]..
Should i try a different 2nd gfx card? Should i avoid pci gfx cards at all costs? Will i
just have to live w/o second monitor? How do i find out which hw resources X is really
using?
