Hardware :: RF Devices Disabled After Returning From Suspend To Disk?

Feb 19, 2010

After returning from suspend to disk, RF devices (wlan and bluetooth) are disabled. Running lspci indicates that no wireless network device is available, and no drivers are loaded. Furthermore, the LED on the front of the laptop remains off - this is always on when RF devices are available. There is an Fn-F1 function key to toggle wireless, but this does not function to either enable or disable.

Rebooting the system does not re-enable the RF devices, and there is no option in the BIOS. The only workaround I have at present is to boot into windows vista and use the Fn-F1 function key. This pops up a small hotkey utility with the option to disable/enable the wi-fi and bluetooth (independently). Upon confirming the dialog, the RF device light immediately illuminates. Rebooting into fedora and wireless devices are working once again.

I am running kernel 2.6.31.12-174.2.3.fc12.x86_64, with the latest compat-wireless drivers. I can provide much more debug information (dmidecode, acpidump, boot logs, lspci etc...), I am just unable to determine what is relevant

# rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

Debian Hardware :: Nvidia Fan Running At 100% When Returning From Suspend?

Sep 11, 2011

I installed the stable version of Debian last night (Debian GNU/Linux 6.0 l) and whenever I come out of suspend, the video card's fan stays at full speed. When I do a regular reboot, this doesn't happen.

Normal behavior is for the fans (cpu and gpu) to go to full speed for a few seconds and then settle on a slower (quieter) speed.

The hardware involved is:
Dell Vostro 400
01:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce 8800 GT] (rev a2)

The install is vanilla (as in "I haven't messed with drivers or configuration files - yet"). Also, keep in mind that I'm a newby - I've just switched to Debian after about two months of Ubuntu and am not too familiar with where everything is or what commands I need to do what, so instead of telling me to change the sync parameters in the nvidia configuration, I need to know exactly what parameter in exactly what file.

Ubuntu Multimedia :: Why Are Devices Detected Even When Disabled In BIOS

Dec 5, 2010

I am having problems understanding how sound capable devices are being used on my Ubuntu10.10 64 bit system. I have an ASUS A8V motherboard with on-board multimedia functions provided through the VIA V8237 chip. BIOS gives me the option to disable this functionality and I have set BIOS this way. I want to use an M-Audio 24/96 card for all sound processing.

However, in applications like Audacity the VIA chip functions are all available and can be set as recording and playback devices. The same is true in ALSA.

Why does 'linux' (I have no idea which part of the OS) ignore the BIOS settings?

Furthermore alsamixer always selects the 'default' devices. Where and how are these set?

<System><Preferences><Sound> hardware tab list 2 'Internal Audio' devices but no M-Audio device. What are these devices? Only 1 of them appears to create any output with the 'Test Speakers' tab. This confuses me completely because the speakers are connected only to the M-Audio card.

None of the profiles for 'Settings for the selected device' match the capabilities of the M-Audio card (1 set of stereo inputs and 1 set of stereo outputs). So where are these profiles coming from? Which do I select for the M-Audio card?

What do the Input and Output tabs in <System><Preferences><Sound> mean? Are these different to the hardware tab? The 'Output' tab lists2 devices for sound output: 'Internal Audio Analog Stereo, Stereo' twice. What devices are these ?

Ubuntu Networking :: WiFi Disabled After Fixing Suspend Mode

Jan 9, 2011

After fixing an issue with sleep mode, my WiFi is automatically disabled on my Ubuntu installation on boot while the switch is on. For some reason, it seems that Ubuntu has an issue communicating with my BIOS. As a fix to this problem: I disabled the C4 sleep state. My Ubuntu installation now boots up fine but the LED on the WiFi indicator glows orange, indicating that it's off; while in Windows it glows blue, indicating that it's on.

Ubuntu Multimedia :: Camera And Mic On Samsung NC10 - TokBox Gives Be A Devices Disabled Message

May 31, 2010

I have a Samsung NC10 and want to use my built in webcam on TokBox. However, when I try to use it, my camera and mic do not work. TokBox gives be a "Devices Disabled" message. It says set to "allow" and click ok, but there is nothing to click. I also can't get the camera to work with video chat in Gmail.

I know the the camera works because I can get it to work in Cheese. The mic, I can't get to work at all. I have gone to the Macromedia site and set the settings to "allow", but still no go.

Both work fine in XP (I have a dual boot), so it's not a hardware problem.

Info:
OS: EasyPeasy 1.6 (same as latest Ubuntu Netbook Edition)
Adobe Flash Player: 10.0.45.2
Browser: Firefox & Chromium (didn't work in either)

OpenSUSE Hardware :: Devices Involved In Wake From Sleep - Suspend To Memory

Apr 17, 2011

I have openSUSE 11.4 KDE (upgraded to Tumbleweed but that's not relevant here). The computer is a Dell Optiplex. My sleep (suspend to ram) and wake (restore from ram) work very well. The box can multiboot to windows 7 as well as to Linux.

In Linux, the restore process is triggered by pressing the power button on the front of the case. No other action will bring it awake.

In windows, the restore process is triggered by the power button but also by moving the mouse or touching the Escape key, spacebar etc.

Here's the question: how do I get the computer to wake in Linux by activating a key (or mouse, whatever) instead of just the power button (which is under the desk and hard to get to)?

Debian Configuration :: Wifi "disabled By State File" After Suspend

Mar 8, 2010

Using Squeeze, I wanted to get KMS + DRI2 and suspend/hibernate working with my radeon card using the Open source driver (my card: ATI Radeon Xpress 200M IGP (5955) PCIE (RC410) is no longer supported by the ATI/AMD proprietary driver). I know my card has problems with suspend/hibernate in User modesetting and from what I've read [URL] it has been solved for some only using KMS.

I followed this instructions by the Debian maintainer:[URL] Of course in reality the available version in experimental is now 6.12.191, and mesa 7.7 and libdrm-radeon1 are already in testing. Therefore I only had to get xserver-xorg-video-radeon from experimental and switch KMS on. It worked ok , except that when I tried to hibernate, it didn't even go into hibernate mode!...the screen went blank and the wireless led shut off, but the fan was running and the keyboard lights were on...

Aside from that I also got the following disquieting messages:

[drm:rs400_gart_adjust_size] *ERROR* Forcing to 32M GART size (because of ASIC bug ?)
radeon 0000:01:05.0: Wait MC idle timeout before updating MC
Failed to wait MC idle while programming pipes. Bad things might happen.

OpenSUSE Install :: No Hibernation (suspend To Disk) With 11.3?

Aug 5, 2010

I just installed openSUSE 11.3 but cannot get hibernation (or suspend to disk) working. It does not go to hibernation but instead it just locks the screen. The relevant error in /var/log/pm-suspend.log looks like below.

According to /usr/lib/pm-utils/sleep.d/30s2disk-check '/dev/dm-1' must be the swap partition. What i don't understand is that why the error says swap partition is not active. There is no error for swap partition during boot time. Boot message says that swap partition is activated.

/usr/lib/pm-utils/sleep.d/06autofs hibernate hibernate:Shutting down automount ..done
success.
/usr/lib/pm-utils/sleep.d/30s2disk-check hibernate hibernate:INFO: checking for suspend-to-disk prerequisites...
ERROR: resume partition '/dev/dm-1' not active, can not suspend

Ubuntu :: Encrypted Swap And Suspend-to-disk

Feb 15, 2010

I have installed ubuntu via the alternate installer, activating encrypted home directories, which in turn enabled to have encrypted swap partitions and disabled hibernation (suspend-to-disk). I understand the arguments for having an encrypted swapspace in these cases. However, I'd like to be nevertheless able to hibernate. Now that the system is already set up, I cannot change and completely encrypt my harddisk via LUKS+LVM as it is suggested in numerous places.Instead, I tried the following. I created two swap partitions (sda7 and sda: one being encrypted via cryptsetup, to be used as a 'real' swap (sda7). Another without encryption, which is not listed in /etc/fstab, so that it is not normally used by the system. I have then configured uswsusp in order to use sda8 as a resume partition:

[code]...

I have decided to encrypt the resume image - I don't care entering a password once every time I resume, it just shouldn't be at every boot. And this way, I can have hibernation without the uncomfortable solution of having my decrypted, open files on the disk as clear text. However, as sda8 is not 'mounted' when I want to suspend, I get the following error:

[code]...

When I try to suspend now, it works. The image seems to get correctly written to sda8. However, on reboot, the image does not seem to be detected and the system is not resuming. I end up with a fresh login screen. would be also to unmount sda8 upon resume, is this better done by entering a hook in /etc/pm/sleep.d or can I just continue in the wrapper script above by executing s2disk.unwrapped only by calling it (without 'exec'), and entering a swapoff line behind it?

OpenSUSE Install :: Suspend To Disk Works But Does Not Power Off (11.2)

Mar 3, 2010

My system does not power off completely after I trigger the "suspend to disk" function. The monitor gets blank and the usb-mouse does not light anymore, but the power led is still on and the pc fans can be heared. Interestingly, neither pressing the power button nor the reset button starts the pc in this state. I have to unplug the electrical power and then press the power button. After that, the system resumes nicely from the hibernation state as it should. I know that the hardware itself is capable of powering off because it worked perfectly before with opensuse 10.2, and I didn't change any bios settings either. I tried the option acpi=force, but to no avail.

Ubuntu :: 10.04 - Prevent Auto Mouting Of Disk Devices?

May 17, 2010

In 8.04 it was easy to adjust, but with 10.04 I've tried to set the policies for udisks with no luck. I want Ubuntu to always ask for my password when a new device/disk is added to the system. If I don't give my password it should not mount the device. What happens now is that all disks added is mounted without any question leading me to believe that the policies is ignored (by a bug) or that I've missed something. I've been through obvious setting in the graphical shell and disabled them. But if they'd been enabled the policies should have kicked in. I do think it worked in version 9.10 when I tested it earlier this year or late last year, but I was waiting for the next LTS. How may I set up Ubuntu 10.04 to make it work as intended?

OpenSUSE Install :: Suspend To Disk Fails After Working For Several Cycles?

Mar 22, 2010

I've been struggling with suspend to disk (hibernate if you prefer) for a while, it works after a fresh boot and for several days' worth of overnight hibernation as I go about my work, but eventually it stops working - it gets to the splash screen but the bar only makes it a little way to the left before stopping, and then after a timeout the system just returns to the "session locked" screen - no real error messages.

I've done my best to try to find out what's causing it to break but I'm really struggling, the suspend process doesn't appear to write anything helpful to the dmesg log or the /var/log/pm-suspend.log - the only thing that I've seen at about the right point in time is cifsd, but I can't be sure that it's a problem with cifs as hibernate continues to work immediately after mounting windows shares with cifs.

System:

Phenom-II X3
4Gb ram
OpenSUSE 11.1

Ubuntu :: Waking From Suspend, To Tell It Needs To Suspend Due To A Critical Low Battery?

Ubuntu :: Sleeps Again After Returning From Sleep

Feb 2, 2010

I configured Dell Latitude D620 to go to sleep mode (suspend to ram) when i close the lid. It suspends ok and then I open the lid. It wakes up ok, but few seconds after goes to sleep again! So I need to press the power button to force it to wake up.

Sleep button works just fine. /etc/acpi/sleep.sh from console too.

/etc/acpi/events/lidbtn

Code:
event=button[ /]lid
action=/etc/acpi/sleep.sh
update:

I noticed that it always goes to sleep again when I wake up laptop by opening the lid. For example if I run /etc/acpi/sleep.sh, pm-suspend or press the sleep button laptop goes to sleep, then i close the lid and when i open it back - the problem occurs.

Networking :: Box With 3 Dedicated IP's All Returning The Same Single IP Address?

Jan 20, 2010

I have a linux box, which was given to me by a company with 3 dedicated IP addresses. My goal was to setup ssh tunnels on all three dedicated IP Addresses.

Via Putty, i am successfully able to create a tunnel to the box's on IP1 IP2 and IP3 - that is i can make incoming connections on all three IP's.

However, my problem lies when i attempt to USE the tunnel. AIn all instances, regardless of the IP i actually tunneled into the box with, it returns IP1 as an outgoing connection, i.e if i setup IE to use the tunnel, it will return my IP as IP1, even though i have created the tunenl via IP2/IP3.

What id liek to accomplish is that when i create a tunnel via IP1, then outgoing connections go via IP1, and when i create a tunnel via IP2, then outgoping connectiosn go via Ip2 etc.

After discussing this with a colleague of mine, he infomed me he had the same problem at one point, and that some configuration on the box was required - however he was unable to recall.

Networking :: Why Is Udhcpc Is Returning Etho0 Instead Of Eth0

May 3, 2011

I'm building a very small netbootable client, using a stripped down custom kernel and busybox v.1.18.4 (stable) with the embedded ifconfig and udhcpc applets

after startup, the initrd is loaded, and the proc, sys, dev and pts folders are properly created and mounted.

/proc/net/dev properly contain eth0 as an ethernet device.

in the init script I execute a background call to udhcpc passing the dhcp.script properly to udhcpc, and dhcp.script is then executed when the bound event occurs.

what I cant get past is udhcpc is passing back the interface evironment variable as etho0 (thats, 'eth' lowercase 'o' and a zero '0', when it should be passing 'eth0', thats 'eth' and zero '0')

I know I could hardcode the eth0, but i was hoping for a somewhat smarter system.
