Ubuntu :: Screen Doesn't Wake Up After Standby / Sort It?
Jun 8, 2010
When I put my laptop to sleep (clamshell close) it goes to sleep and is a happy laptop.
When I open the laptop, I can hear the thing going and waking up. However the screen stays off. Brightness keys do nothing. (however they did nothing in the first place as I'm using the NVIDIA driver). I have to do a hard reset to fix things.
The strange thing about this is Sleeping / Waking up has never been an issue till about today.
Like subject says, everytime my computer put the monitor on standby when I wake up the monitor the computer keeps loggin me out of my account, have to log in everytime i wake up the **** monitor, anyone knows a way to fix this behavior?
I'm using Karmic since November and standby/sleep has always worked fine. Some weeks ago, it stopped working fine.
After a reboot, I can put the system in standby only once. If I try standby after that, the system seems to do a normal standby, but it resumes at the moment the fans would normally stop working.
I tried different things like the s2ram program, pmi action sleep, etc. I went to the BIOS and tried a number of things, one was succesfull: disable USB. When USB is disabled I can go into standby every time. When I enable USB again (even with no devices connected), standby only works once again.
So, how can I disable USB at the moment I go into standby?
This is probably really a quick fix but I cannot seem to find it. When I close my laptop lid it brings me to the standby screen which then asks me to put my password in, when i log in I managed to make it not ask me for a password but on the standby screen it still does.
It's just annoying me a little and wouldnt mind just being able to open my laptop and go. also same kinda problem with installing software, always asking for passwords but I guess i can live with that one.
Am currently using 8.10 (xubuntu). The machine's "issue" (I've searched for a reference, but the one I found was a forum thread with no answers) is that when the display is set to go to sleep after 8 minutes of idleness in the power manager, it projects a black screen instead.
I'm not sure what different 'power saving modes' a display/OS usually has, but in Windows, when set to 'go to sleep' the screen goes into standby, i.e something like 'no signal', and from what I've read a lot more power is saved in that mode than by simply showing a black screen.
It was the same when I was running 8.04 with a different graphics card, if that matters. Haven't been able to try a different display. Screensaver and timing and resume normal video out works ok.
Plenty of people seem to be having issues with the nvidia graphics drivers, so I thought I'd add my woes to the heap. My issue is that I run two screens under twinview, but the second one doesn't work for some reason. More specifically, the Nvidia-settings tool is able to detect my second monitor, and I'm able to assign it a resolution and position and the like, and my desktop seems to extend over to where the second monitor is, but the monitor just remains in standby mode.
This happened with the drivers proprietary drivers that Nvidia tried to install (version 173 I believe) so I removed them and tried to install the 195 drivers manually, which I eventually figured out how to do (by blacklisting the nouveau module amongst other things). This still didn't fix things, and gave me the same issue.
(As an aside, where can I find the nvidia-glx-195 and nvidia-modaliases-195 packages, as they seem to have disappeared from the LP-PPA-nvidia-vdpau repository where they apparently used to be?)
The strange part though, is that my second screen works fine if I don't install any nvidia drivers, and just use the System->Preferences->Monitors applet. The second screen comes out of standby and works nicely.
One other little thing I've noticed that may have something to do with it, is that if I switch the outputs that the monitors are connected to, the other monitor will work. The output whose monitor doesn't work is always the one that has the DVI->VGA converter. Could this have something to do with it?
I upgraded from 10.11 to 11.4 and as far as I can see most things work as they did before. However, I have my machine to "go to sleep" (is that suspension or hibernation?) after 2 hours and when I, now after the upgrade, press the "wake up button" the machine fires up but the screen remains down. Ie, the screen is actually not receiving any signals from the computer? Any setting I can change? It worked fine with 10.11!
As part of making a encrypted private folder i told encfs to encrypt swap space on my pc knowing that this would probably break sleep and hibernation. That said i just turned on ubuntu for 5 mins, had to go away for a bit, when i came back to unlock the screen my password was not being accepted, and another 5 mins later the screen said that my session had timed out-i had to do a cold reboot Does this mean i cant lock the screen anymore?
I am trying to remotely wake up my computer. I am using the wakeonlan tool as follows wakeonlan -i 146.x.x.x 00:0f:.I have used wireshark on the remote computer and verified it was getting the magic pack. wireshark sees the packet, and immediately the remote computer sends an ICMP dest. unreachable (port unreachable) packet back, although I assume that is normal.On the remote computer, I used ethtool so I am enable to verify that suports wake-on is set to "g" or magic packet.
I believe that wake-on-lan is enabled in the bios. I have a hp dc5000, so I turned on S5 wake on lan in the bios. However, the computer does not wake up.My assumption is that once the computer is off, the router doesn't know where to send to packet because that ip is not there anymore. Does that make any sense? What other troubleshooting steps can I take? I don't have control over the routers though.
I'm getting some trouble with Wake on Lan. The main question is: when I shutdown a PC through Windows, the WOL works well, but it doesn't happen when I shutdwon the same PC through Linux. It happens in all of my PCs here in the company.
When I wake up from hibernating I get a black screen, no keyboard. How to fix this, been a problem since jaunty? It's my only problem with ubuntu. I get (please wait waking up screen) then black screen and no keyboard control. I have to hard reboot.
I cannot install Ubuntu 10.04, or even boot into the live CD. I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.
When I close the lid on my laptop, it blanks the screen but does not sleep or hibernate. When I open the lid, the screen wakes and everything runs, but my mouse cursor has disappeared. I can restart the desktop ctrl-alt-backspace and get my mouse back.

I've got Ubuntu 9.10 with a user account for my wife, and one for myself. "Wake-from-screensaver" should result in "choose user" without having to enter any password. I know how to do that in Windows, but I'm not good with Linux (yet). get past the login screen without passwords (after booting, and after choosing "switch user"), but once the screensaver kicks in and I wake it up again, the system does not present the "choose user" screen. Instead, it either turns off the screensaver and presents the desktop of the most recent user, or (if the screensaver is set to lock the screen) prompt for the user's password (which can be handily surpassed by clicking the "switch user" button and choosing the same user again). So, the login ("choose user") screen has been dealt with. How do I make the (any) screensaver return to the login screen at wake, rather than to the current user's desktop? Windows can do this, I'm sure Linux can too - but how?
Upgraded online from 10.04 to 10.10 this morning....went OK I think! Was offered option to upgrade further to 11.04...and went for it!! Returned later to a blank screen.....unable to wake the machine....no disk activity Now have some function via a live CD......any thoughts on how I can proceed from here? I would like to persevere with the 'upgrade' route, as a fresh install will result in much loss of files
Is there a config file to toggle whether the screen is locked after hibernation? I looked all over preferences but if it's there, I missed it. In Ubuntu, the screen was always locked after waking up. In Squeeze, it's going directly to desktop. It's not a biggie but you never know when someone might try to access your account so I kind of liked that it would wake up locked. Maybe it's doing that because I'm the only user on the system?
I am very much new to Debian. To have a feel and check if my laptop (HP Elitebook 6930p) is supported I decided to use a live USB option. I know how to create a live USB disk using Ubuntu and using the same knowledge I created the USB disk and tried to boot using it. The system starts to boots off the USB drive and then is stuck at a point where it fails to identify my HDD. Here is what I did a) downloaded the debian-live-508-i386-gnome-desktop.iso/debian-live-508-i386-gnome-desktop.img/debian-live-507-i386.iso (I tried with all 3) b) created a live USB using unetbootin c) tried to boot from live environment
My laptop's hard drive is encrypted using SafeBoot. After all the 3 debian images failed to boot I tried with other Linux flavors such as Mint and Ubuntu. Interestingly Mint and Ubuntu boot. Is there some thing I need to take care of?
I downloaded banshee because i knew that could put movies on my ipod, but everytime i run banshee my ipod doesn't show up. i tried started it, then plugging it in and still didnt show up. Anyone knows what the problem is?
I am a newbie in Linux and have only been recently using it. I have faced a problem with my the firefox browser launch. Recently there was a update (to generic version 18.104.22.168) after which the browser fails to start. It gives the message starting Firefox web browser and then dies off. I tried searching for some already posted answers but couldn't find much.
I'm brand new to Ubuntu. I'm normally running w7, but since i had an unformatted partition spare i figured i should install Ubuntu to it (i've installed ubuntu once before, but i never really used it).
Problem is i can't even start the live OS or installation. As soon as i get past the boot-screen the whole screen turns violet, flickering.
So yesterday I had plugged my laptop into one of the tv's at work using HDMI, it worked great but no matter where I played in the setting's I could not figure a way to play the movie and be able to close my laptop lid with out it going into a sleep mode. I tried it in the power management but could not get it to work.
Every time I boot my machine, some of the playback values in alsamixer are set to 0 and are muted, so I have no sound.
The thing is, I have tried setting these to normal levels and then run sudo alsactl store. Then, if I run sudo alsactl restore after I reboot, the sound comes back up. However, if I have alsactl restore in /etc/rc.local, it doesn't work: I still get muted sound when I reboot. I have to run sudo alsactl restore manually each time.
I have already checked whether /etc/rc.local runs at startup, and it does. Also, I know that /var/lib/alsa/asound.state contains the correct values, because when I run sudo alsactl restore, the sound returns to normal levels. So what remains is either alsactl restore doesn't work in /etc/rc/local, or something runs after it and mutes the sound.
Everything went fine this morning on the Install. Then the box said there were 121 updates. I click YES to update. After an hr updates had finished, and reboot was necessary. Only a black screen came up. I have 2 lights on my keyboard blinking, no hard drive activity light. Waited several minutes, nothing. So I did a reboot back into my WinXP. Any suggestions?
