[SOLVED] Module not loading on boot

squinky4 · 2011-08-19 16:12:11

So I have a port replicator plugged into my laptop with an external monitor. I have everything working fine using the udlfb module. I would really like to get this module to start whenever I boot into linux.

Here is my rc.conf

#
# /etc/rc.conf - Main Configuration for Arch Linux

# -----------------------------------------------------------------------
# LOCALIZATION
# -----------------------------------------------------------------------
#
# LOCALE: available languages can be listed with the 'locale -a' command
# DAEMON_LOCALE: If set to 'yes', use $LOCALE as the locale during daemon
# startup and during the boot process. If set to 'no', the C locale is used.
# HARDWARECLOCK: set to "UTC" or "localtime", any other value will result
#   in the hardware clock being left untouched (useful for virtualization)
#   Note: Using "localtime" is discouraged.
# TIMEZONE: timezones are found in /usr/share/zoneinfo
# KEYMAP: keymaps are found in /usr/share/kbd/keymaps
# CONSOLEFONT: found in /usr/share/kbd/consolefonts (only needed for non-US)
# CONSOLEMAP: found in /usr/share/kbd/consoletrans
# USECOLOR: use ANSI color sequences in startup messages
# VERBOSE: Verbose level (from 1 to 8). man 3 syslog for level info

I can use modprobe to load the module after I log in

sudo modprobe udlfb

dmesg does not mention anything about it until I do the modprobe:

Any thoughts on how to get it to load automatically? The only thing I have in modprobe.conf is

blacklist bcma

Thanks!

You're sure the module isn't blacklisted by some file in /etc/modprobe.d/?

Yeah, checked and rechecked...

squinky-mobile modprobe.d $ cat /etc/modprobe.d/modprobe.conf
#
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)
#
blacklist bcma
squinky-mobile modprobe.d $

squinky-mobile modprobe.d $ cat usb-load-ehci-first.conf
install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install ohci_hcd $CMDLINE_OPTS
install uhci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install uhci_hcd $CMDLINE_OPTS
squinky-mobile modprobe.d $

Not sure what the usb-load-ehci-first.conf does, maybe this is my problem?

Edit: NVM, you clearly don't have any other blacklist files there.

When I was searching for files that go in /etc/modprobe.d/, I found there's a /lib/modprobe.d/ folder that's part of udev. It contains a framebuffer_blacklist.conf file that blacklists udlfb. It's a shot in the dark, but maybe try removing that line?

That seems to have done the trick, thank you!

framebuffer_blacklist.conf is not listed as a backup file in the udev package! You will lose your changes if you do not do one of the following:

1) Copy the file higher in the modprobe.d hierarchy so that it overrides the rule provided by udev: `/etc/modprobe.d/framebuffer_blacklist.conf'. It's important that it have the same filename.
2) Add the file to NoUpgrade in /etc/pacman.conf as lib/modprobe.d/framebuffer_blacklist.conf (note the lack of the leading slash). If this file ever changes in the udev package, you'll have a .pacnew created on upgrade.
