Verzeichnis /sys aktualisieren?

[michel8]

Hallo Zusammen,

beim Oneric-ISO habe ich derzeit folgendes Problem:
Nach dem Einspielen vom nvidia-paket sind die i2c-devices nicht alle im /sys-Tree eingetragen.
Wenn ich ein startx ausführe sind die folgenden Einträge dann aber vorhanden:

Code:

    /sys/devices/pci0000:00/0000:00:10.0/0000:02:00.0/i2c-4
    /sys/devices/pci0000:00/0000:00:10.0/0000:02:00.0/i2c-4/uevent

Gibt es einen Linux-Befehl, mit dem ich den Tree in /sys neu einlesen kann,
oder was könnte noch ein Grund dafür sein, dass die i2c-devices nicht gleich unter /sys aufgelistet werden dann aber nach einem startx dort auftauchen?

Möglicherweise sind die fehlenden i2c-Einträge oder/und die fehlenden

Code:

    /dev/nvidia0
    /dev/nvidiactl

daran Schuld, dass der soundcheck nicht ootb tut

Ach ja, ein Power-on-reset kann ich an der stelle leider nicht brauchen...

Danke im Voraus
Michel

Nachtrag:
[pre]i2cdetect hilft auch nicht weiter, i2cdetect -l gibt gar keinen output...[/pre]

Mit dem /sys Tree hast du als User normalerweise nix zu tun. Der /sys tree bildet die hardware aus Kernel Sicht ab.

Nach dem Einspielen vom nvidia-paket sind die i2c-devices nicht alle im /sys-Tree eingetragen.

?

Was hat die Installation eines Pakets mit /sys zu tun? Die Informationen dort ändern sich höchstens, wenn neue hardware hinzukommt oder ein Treiber geladen wurde.

Genau, Wirbel.

Der nvidia-treiber kommt damit, und ich denke ohne den werden nicht alle Features der GT210 beim vorangehenden booten erkannt und unter /sys eingetagen...

Gibt es eine Möglichkeit, an einem Reboot vorbeizukommen?

Irgentwie müsste es gehen, denn ein startx (was auch immer dann in folge passiert) reicht schon um die 12c-devices unter /sys anzulegen...

Danke im Voraus
Michel

Versuchs mal eher mit

modprobe -r nvidia && modprobe nvidia

[michel8]

Komisch,

modprobe -r nvidia bringt "kein Modul nvidia" und ein lsmod nennt das nvidia-modul mit einer Verwendung von 0 ?
ein modprobe nvidia ändert daran nichts und auch die i2c-devices werden nicht angelegt...

Als wenn das nvidia-paket den nvidia-treiber nicht ganz fertig einbaut - nur was fehlt?
in reboot ist ja definitiv nicht zwingend, wenn ein startx auch hilft

Hast Du noch eine Idee?

Danke
Michel
