Ubuntu :: The Wifi Won't Work And That Can't Use Hibernate?
May 14, 2010
my Eee PC has various troubles with the current Lucid kernel (2.6.32). These include, that the wifi won't work and that I can't use hibernate. A netbook without wifi is a little bit useless I even tried the usual bugfixes, that you can find in the web (installing the original RAlink drivers, updating to 2.6.33), but nothing really worked.As a consequence, I downgraded to Karmic again, were everything just worked fine.My question is now, is it possible to run Lucid with the older kernel available in Karmic?

After I resume from hibernate with my cpu frequency manually set to the highest settings (2ghz) the network manager shows not wifi APs. "wlan0" shows under both ifconfig and iwconfig but "iwlist wlan0 scan" says no results. "sudo iwlist wlan0 scan" also says no results. I've tried rmmod then modprobe with no luck. Rebooting is the only way I can get WiFi working.
I can get wifi working again by:
- rebooting
- changing the cpu scaling to a lower setting then hibernate/resume
- changing the cpu scaling to a lower setting then 'sudo rmmod ath9k; sudo modprobe ath9k;'
I am using Ubuntu 10.04 with Atheros ar5008 (AR5BXB72) using ath9k drives
Code:
$ lspci |grep Atheros
0e:00.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)
Code:
$ uname -r
2.6.32-24-generic

I am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address. And if I try to change networks without hibernating I get the same problem. Also, I notice that the network name is stagnant. I connect to multiple wifi networks a day because of school. When I leave my "home" network and connect to my "school" network WICD still says "Homebtaining IP address" even thought it should say "schoolbtaining IP address." My thoughts are that it isn't releasing the network properly and when its trying to connect it can't because it still thinks it's connected. The only solution I have found is to restart my laptop every time I want to connect to a new network, or shut down every time I am done using my laptop, which is a major inconvenience.
Here is what I am using:
HP tx2000
Broadcom BCM4322
Ubuntu 10.04
WICD 1.7.0

I own an Acer Aspire 5552g. I have installed 2 systems on it: Windows 7 and ubuntu 10.10. Everything works fine except wifi. There is a lot of threads connected to this topic, but none has solved my problem yet. The problem occurs when I hibernate Windows and then load ubuntu - I get unable to turn wifi on. As rfkill says - it is hard blocked. It wouldn't be a problem if i had a hard switch for wifi. but I only have fn+F3 for that, which somehow fails to work in my situation.
Code:
igor@igor-Aspire-5552G:~$ rfkill list
1: phy1: Wireless LAN
Soft blocked: no
Hard blocked: yes
If I reboot Windows and then start ubuntu - everything's fine and working. fn+F3 turns wifi on and off as expected. I will provide some more info: when wifi's working:
Code:
igor@igor-Aspire-5552G:/sys/class/rfkill/rfkill1$ cat state
1 when it doesn't:
Code:
igor@igor-Aspire-5552G:/sys/class/rfkill/rfkill1$ cat state
2 some additional info:
Code:
igor@igor-Aspire-5552G:/$ lspci -nn

When I try to hibernate, the computer just goes to a blank, black screen and doesn't turn off. I have to hold the power button to get it to shut down, and when I turn it back on none of the programs running before hibernation have been saved.

I Installed Ubuntu 10.04 with Logical Volume Management last month and then upgraded to Ubuntu 10.10 and noticed that I have been loosing power faster than I have been used to. I have realized that I didn't have a hibernate option. I should be able to hibernate because I have over 5 GB LVM swap partition and only 2 GB of ram on my Laptop. How do I get the hibernate feature back?
EDIT the original installation was with encrypted home but I moved off of the encrypted home.

I am using Xubuntu 9.10, 2.6.31-17-generic kernel. Video driver: "ati".I have only been using Linux for less than a year now but I have never been able to get hibernate mode working. Had the same problem on previous kernels and with Nvidia drivers. Tonight I tried removing all traces of any nvidia drivers hiding in my system (I recently changed to an ATI card), and also upgrading to grub 2. Still no luck.If I use the "hibernate" option from the shutdown menu, I just get a black screen with a blinking cursor. If I use s2disk, I get a little bit more of a hint, but still not very helpful. Then it just locks up after that. Power is still on and it never shuts down. I have a 6 gig swap partition set up that is enabled, so it is definitely not a swap issue.

I've recently installed Ubuntu 10.04 (amd64) on my MacBook 3,1 (1GB memory). Most things work perfectly on install, and I've got the iSight working now too!
However, although suspend works fine, hibernate does not. When I try to hibernate, the screen goes blank with the back light on for a few seconds, then the screen goes off completely for about 0.1 of a scond and I hear the optical drive whirr (like it does when booting), and then about 4 or 5 seconds after that it finally powers off.
Then, when I restart, I see the rEFIt menu, then the GRUB menu and it appears to boot like normal and *not* resume from hibernate!
I'm not sure what log I should look in? When I look in /var/log/pm-suspend.log the last line says "performing hibernate", but there's nothing about even attempting to resume.
UPDATE: Forgot to mention, I have a swap partition that is larger than 1GB.
UPDATE 2: Also, after attempting to hibernate, when the system restarts, WiFi has been disabled -- I have to double-tap (right-click) on the WiFi icon and re-enable it. I *think* this is because the hibernate process disables networking, but it then fails to re-enable it because is fails to resume.

The OS is Lucid 64-bit . Before I begin I must say suspend/hibernate works fine with 3 other machines, so I'm trying to find out what's wrong with this one. I tried [URL].. and also I tried changing acpi-support. It currently is as this:

Why doesn't Hibernate work in Ubuntu 10.10?
I have tried to research the problem and suspect that the hibernation function is not a default function of the system. But how do I install it.

I've re-partitioned my existing windows xp disk to do a dual boot with Ubuntu 10.04 Lucid. The installation went fine and I am able to use both the operating systems just fine.
But when I boot into windows xp I donot have the hibernte/sleep options available anymore.
debug the issue and get back those options ?
Note: I have made the windows as default boot option in grub.

I have recently switched to Ubuntu from Windows Vista. But I am having a few problems, any pointers will be grand.First sleep and hibernate do not work. My laptop sleeps or hibernates fine, but on awake I just get a blank screen and the hard drive doesn't spin at all. This also disables the network manager, which is a real pain.Also for some reason I can't enable special effects. I have the ATI Radeon 200M series integrated graphics chipset.eres some spec details:

I've been running 6.0.2 amd64 stable since release day and recently have noticed my suspend and hibernate do not work. Normally I have transmission running and have set it to not enter sleep mode while torrents are active. However today I have not had transmission and was wanting to see if the sleep mode options would kick in. So I have set my display to "sleep when inactive for" 5 mins (this works perfect)
I have set "put computer to sleep when inactive for" 10 mins (this does not work at all)
When I try to manually test suspend my display flashes black for a few seconds but remains backlit, then asks me to log back in
When I manually go into hibernate mode my display turns off, pops back on for a second and in a terminal says something about a usb device (something failed but it happens so fast I cannot read it)

My desktop is a Compaq CQ5110F. It's a dual boot system and Fedora 11 resides on sda3 of hard disk (WD 3200AAJS-6).Both suspend and hibernate don't work, but the symptoms are different. For hibernate, after resume, there are some messages (??) about register errors quickly flashed on the screen, then the logon window shows but the system hangs. For suspend, I cannot wake up the system by hitting some keys on the keyboard. After I press the power button, LCD doesn't get any signal. I remember hibernate worked when I was using Fedora10, but wireless card did not automatically reconnect at that time. Also hibernate works fine for vista.

I have installed Ubuntu as wubi (next to windows 7). When I expect the computer to shut down (either to hibernate or as part of, you know, shutdown), it doesn't. All the programs end, I am logged out, but I still have a picture on the screen (ubuntu default picture).

So here is my problem what i am currently having. I am going through a serious issue right now. My laptop crashes when SUSPEND/HIBERNATE or unplugging the laptop's charger.

Wubi doesn't let me set the swap file size, so on installation it only creates a swap file of a few hundred megabytes. Because of this, i cannot hibernate my netbook (eeePC 1005HA), which has 2 GB of RAM.
Creating a 2 GB swap file alongside of the original one using the tutorial here did work, but hibernate doesn't seem to work with it. For this reason i thought increasing the original swap's size instead of creating more would be a way to solve my problem.

I recieve the following error:
Cannot find swap device, try swapon -a
/bin/echo: write error: No such device
If I type swapon -a, I get something like this:
swapon: cannot find the device for UUID=4d79c009-9464-41d5-9f78-90644bca9ba3
It worked great before I did the upgrade... I've upgraded to 2.6.37-rc5.

I'm using pm-hibernate, and would like to reboot the machine after it's done hibernating, rather than having the machine turn off.Is there a way to do this with pm-hibernate, or any other Linux hibernate thing?

What is the deal with Ubuntu and power states? "Suspend" and "Hibernate" don't do anything. Whether I invoke one manually, the most that happens is that my screen goes blank. The monitor does not go to standby, my hard drives don't spin down, and the machine doesn't go into standby. Whenever I try to start the "Power Management" applet (System->Preferences->Power Management), it seems to hang. Takes a long time - up to a couple of minutes - for a window to appear. I also just noticed that one of my HDD's seems to be running constantly, even though I'm not moving any files around. Not sure where to start straightening things out.

Two days ago the Update Manager installed kernel 2.6.32-25.After a re-boot Suspend is broken, it takes about 30 seconds to suspend and will not recover.Also the wi-fi won't work at all.Booting with the previous kernel I have no problems.Has this happened to anyone else ?I was thinking of installing 10.10 64bit, I wonder if it will work!

Just got Ubuntu 9.10 and I'm liking it a lot, but my computer refuses to go into hibernate or suspend. I have a Dell M1530 but I don't really think it's a dell hardware issue because it's not just when I close the screen, it's also when I click suspend or hibernate from the menu.

I have an Asrock A330GC, with onboard ethernet, and an Engenius PCI card for wifi.I installed ubuntu server 9.10 no problems, and it picked up my ethernet in the installation with no difficulties.I couldn't get 9.10 to do what i wanted, so I tried installing 8.4 instead. This however didn't pick up any of the drivers, so i couldn't get online.So i reinstalled 9.10, only to find that no couldn't find network in the installation.Absolutely NOTHING has changed, the ethernet cable still plugged in, and if i plug same cable into my laptop, it works fine.Any ideas people?ifconfig doesn't mention any eth0, just lo, with an ip of 127.0.0.1 and amask of 255.0.0.0 which i'm fairly certain means its dead
