Currently I only only resume from suspension by pressing the power button. I learned that by editing /proc/acpi/wakeup one can enable resuming from other devices. But how to figure out which is for which device? Here is my /proc/acpi/wakeup file:
Code:

How do you actually remove and install kernel when the system is not booting.
View 4 Replies View RelatedI'm trying to move an existing FC10 install (created by someone else) from a 160GB WD1600AAJS SATA disk to a 160GB WD1600AAJB PATA disk (cursed trend of horizontally mounting SATA connectors at the end of the motherboard means the latest rev mobo doesn't fit in our enclosure!). I've used DD to copy the disk image from one to the other, but when attempting to boot, I get the following error:
Code:
Unable to access resume device (UUID=946f216f-0c24-4b02-a996-f42059970de7)
mount: error mounting /dev/root on /sysroot as ext3: no such file or directory
That particular UUID maps to sda2, which is the swap partition. Interestingly, both the SATA and PATA disk come up as /dev/sda on the motherboard. I kind of grok that the UUIDs are substitutes for directly naming the disks, and that they're referred to in fstab, initrd-2.6.27.12-170.2.5.fc10.i686.img, and in /dev/disk/by-* I'm guessing the problem is that the GUIDs (at least the one for swap) are no longer the same. How are they assigned to the partitions during boot?
I tried doing
Code:
swapoff -a
mkswap /dev/sda2
swapon -a
and put that new GUID in fstab and into initrd-* (using some steps I found elsewhere on how to gunzip/rezip it).At that point, I get a kernel panic on boot
Code:
Kernel panic - not syncing: CFS: Unable to mount root fs on unknown-block(0,0)
So I'm guessing that the other UUUDs have changed as well and I need to update them. How would I figure out what they are? I suppose I could change the references to /dev/sda*, but I didn't build this original image and I'm thinking whoever did had a good reason to go with UUIDs.
I have FC6 system with kernel 2.6.22.14-72.fc6 When I rebooted my system, I got error message "unable to access resume device (LABEL=SWAP-sda8) then it went to fsck automatically to all the partition and then stop (failed)

When I suspend my computer and then resume later in the day my USB keyboard locks up. The only way I have found to reset the keyboard is to disconnect the USB cable from the USB port and then reconnect it.
View 9 Replies View RelatedWhen I resume my system after choosing the "Suspend to RAM" option, the login prompt appears but the keyboard doesn't work at all. (Caps/Num/Scroll don't light up either) The mouse, however, works fine and I'm able to click on the on-screen elements. Since I'm not able to login, I'm forced to reboot and abort the session. Note that this does NOT happen with the "Suspend to Disk" feature. (ie, it works fine).

I was trying to get this feature: wake up my htpc from s3 with my remote control and the solution is to modify /proc/acpi/wakeup and a descriptor in /sys. Here are the details: I'm using a Microsoft IR receiver for MCE remote that appears as dev 2 of bus 2 in lsusb

That's USB0 I have to enabled, why not usb 1 or 2 (bus 2 in lsusb)? Moreover why are all the disabled/enabled preceded with a star and S4 and not S3 mentioned? Nevertheless that wasn't enough to get it work. I looked in gconf-editor in apps/gnome-power-manager/general but I have no can-suspend or something similar... (I'm running on 10.10, with 10.04 I could suspend only once, afterwards the computer didn't go to suspend, just black screen then login screen). So I looked in /sys/ and found that 'cat /sys/bus/usb/devices/2-1/power/wakeup' (notice the 2.1 as bus 2 device 2 (0,1,...) gave 'disabled' so a echo enabled > /sys/bus/usb/devices/2-1/power/wakeup and now I can wake-up with the remote when I want.
What I don't understand:
Why USB0 in /proc/acpi/wakeup ?
Why have to change in /proc and /sys ?
Is it possible to automate this to get it work even if I change the usb port the receiver is plugged in ?
I'm running Debian 8.1 KDE on a 2007 dv6 laptop. Model number is worn off. lol but the specs:

First off, closing the lid to my laptop doesn't trigger suspend, or anything no matter what I set it to in power options.
I can suspend using "systemctl" or suspend from the "Leave" menu, but upon turning my computer back on, my touchpad and keyboard don't work.
Sometimes, my touchpad will start working after about 15 seconds, but the keyboard doesn't come back. I have to hard reset.

I am having trouble with a rather peculiar timeout during resume from suspension and I was wondering if any of you have encountered the error or might have some leads as to what causes the problem.I am using Gentoo Linux with TuxOnIce patched kernel. While both hibernation and suspension works as advertised, there is a rather irritating timeout while trying to resume from suspension. Each and every time it takes about 60s for notebook to resume back to X session again, no matter what the conditions are (i.e. USB deviced plugged in, etc.)

I've bought this remote control that sais it works in Vista, XP etc. without any driver. Basically it has a bunch of buttons that replace the mouse and a bunch of others that replace basic keyboard functions (arrows, enter, escape). It has a USB IR receiver so I thought I could simply use it as a lirc remote in Ubuntu.
However, it sais absolutely nothing on it except for "PCremote" so during lirc installation I have no idea what to choose. And, interestingly, I accidentally discovered that it works in Ubuntu, too, out of the box. Controlling the mouse and acting like a keyboard. Is there a way I can forfeit current functionality and just get it to work as a customizable lirc remote? Or even better, keep current functionality but change it only for certain apps (xbmc, vlc etc)?

If I suspend my notebook it starts the usual slow orange blinking indicating the suspend mode got reached. There is also evidence in the various log files that this works. If I try to resume it hangs a for 3 seconds and then I get the hdd-password screen from my bios and the notebook boots from zero. I couldn't find anything in /var/log/messages nor dmesg. If I first boot to windows (grub 2nd partition) and then restart and boot to linux, all the suspend works fine
how do i disable the screen lock after i wake my computer from suspend? i would prefer to be able to just wake the computer up and have it go right to the desktop, without having to enter a password. i used to use ubuntu until today, and i remember having to run "gconf-editor" and then switching off on "lock_on_suspend" under apps/gnome-power-management from the menu that popped up. i tried to run "gconf-editor" in fedora 15, but that doesn't appear to exist. i've searched around and haven't been able to find an answer, so i'm wondering if anybody knows what to do?
View 3 Replies View RelatedI am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).
