I only can use Jack2 from svn, if it shouldn't be available, than I'll
build it myself. This is regarding to hw MIDI jitter. Only Jack2 is hard
real-time capable regarding to this issue.

Ok.

Ok. Might be the same style as for Ubuntu, hence I'll build dummy
packages and install Jack2 from svn. No big deal.

*?* I don't need Jack from a repository, I just asked, because this
would be less work.

Why do you think so?

Regards,

Hi Andrei :)

I don't think so, it's a declarative statement.
I guess nobody wish to have a vertically frequency of 60Hz ;), it's not
very pleasant to look into a stroboscope. In addition I wish to be able
to select the screen resolution I like, 1152x864 @ 90Hz.

Then I have several needs and need several drivers. I'm used to switch
the drivers automatically at startup, by adding

rm /etc/X11/xorg.conf
case $(uname -r) in
*rt*)
cp /etc/X11/xorg.conf.nv /etc/X11/xorg.conf
;;
*)
cp /etc/X11/xorg.conf.nvidia /etc/X11/xorg.conf
;;
esac

to /etc/rcS.d.

At the moment I urgently need help regarding to xorg.conf or any other
solution that enables me to select the driver, and to get 1152x864 @
90Hz.

The graphics is a NVIDIA GeForce 7200 GS aka 7300 SE. The CRT monitor is
an Lifetec/Medion MD1998JB J91B.

I never had issues with old Debian/Ubuntu and Suse installs. I ordered
some new gear, a RME HDSPe AIO sound card + a 8 analog IO ADAT device
and some other stuff. It was delivered yesterday, but it's still
packaged, because I'm unable to set up a new Linux DAW. Old Linux DAWs
are still available by backup archives ;).

At the moment for my Debian install, the mouse wheel isn't working, as
soon as I add a xorg.conf. Without an xorg.conf the mouse wheel seems to
work all the times. I stopped trying to use old xorg.confs.

I run Xorg -configure in recovery mode.

The mouse is a wired Trekker Wheel Mouse 2.0A PS/2.

This is what Xorg -configure generated

Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/input/mice"
Option "ZAxisMapping" "4 5 6 7"
EndSection

While for Ubuntu at least the frequency and resolution can be set by an
old xorg.conf, for Debian frequency and resolution are still not set :(.

Any help is very much appreciated.

Best,

Ralf
