Hi,
i'm trying to get suspend2 works on my system. I have problems with 855resolution with vesafb-tng.
This is /etc/init.d/855resolution
| Code: |
#!/sbin/runscript
# Copyright 1999-2005 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: /var/cvsroot/gentoo-x86/sys-apps/855resolution/files/0.4/init,v 1.1 2005/06/19 22:07:03 fafhrd Exp $
depend() {
before xdm
}
checkconfig() {
if [ -z "${replace[0]}" ] || [ -z "${with[0]}" ]
then
eerror "You need to set at least one replace/with pair in /etc/conf.d/855resolution"
return 1
fi
}
start() {
checkconfig || return 1
ebegin "Running 855resolution to replace ${#replace[@]} mode(s)"
i=0; return=0; retval=0
for target in "${replace[@]}"
do
/usr/sbin/855resolution $target ${with[$i]} > /dev/null
retval=$?
if [ "$retval"!=0 ]; then return=$retval; fi
i=$(($i+1))
done
modprobe vesafb-tng # <-------------- LOOK HERE!
eend $return
}

Please look at the last lines. The script patches the video bios and then (as soon as possible) modprobe vesafb-tng in order to get console working at 1280x800 pixels.
The problem is, when i try to resume from suspend, the computer freezes.
If i delete the line "modprobe vesafb-tng" from the script all goes ok
that is, the problem is with vesafb-tng module. I think suspend2 (on resume) restart 855resolution, and modprobe (twice) vesafb-tng.
I want to:
1) on suspend, remove vesafb-tng module
2) on resume, restart 855resolution
this must works. This is my /etc/hibernate/suspend2.conf
| Code: |
UseSuspend2 yes
Reboot no
EnableEscape yes
DefaultConsoleLevel 1
Encryptor none
Runi855resolution 1 # <---- THIS SHOULD RESTART THE SERVICE
UnloadModules vesafb-tng <---- THIS SHOULD UNLOAD VESAFB-TNG
Include common.conf
|
I think the module isn't unloaded and the system freezes. In fact, if i try:
| Code: |
localhost gremo # rmmod vesafb-tng
ERROR: Module vesafb_tng is in use
|
Probably so also "UnloadModules vesafb-tng" will fails.
How to force unload this module? |

if the module is in use, you can force it to kill the programs that are using it by adding the following to your /etc/hibernate/suspend2.conf (or even to common.conf):
| Code: | | IncompatibleDevices /dev/fb0 |
and then run hibernate with the -k option. |
