Ubuntu Installation :: Display Doesn't Wake Up After Suspension
May 14, 2011
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!

Running Fedora 12 with all the latest updates installed.
Using Radeon card with the experimental Mesa 3D driver. (The opensource stuff rather than ATi's closesource driver.)
Most of the time when it goes into screensaver, and turns off the monitor, it can't be wake up again.
The OS is still running, I can access it's web server, ssh, everything, just can't use the desktop!!
I have tried nomodeset and pcie_asm=off in grub but neither of them fixes the problem.
What else should I try?

I came back to debian after trying many others because it installed flawlessly and worked. I'm on the testing channel and upgrade nearly everyday and after a recent upgrade my xsession (Xfce4) display won't wake up any more after I close and re-open the lid. I know the box is awake because I can go to a ctr-alt-fn console login and use it normally. How can I track this down? And is there some way I can restart the gui display from the console without losing what was running before I shut the lid? Right now the only way I can recover is to restart the computer.

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.

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.

i have a large data file for gnucash of several years in age. when i did the upgrade, gnucash starts and loads, and the main account appears to load, but there is nothing displayed. just an empty gray space where the alternating colors of the ledger should be.the account listing loads, and i can view other smaller accounts just fine. but the main ledger does not display. however, if i click on some areas of the screen, it will display what i assume is the underlying text in the bottom status bar.
and when a window or some other graphic element 'over writes' any area, some remnants of the former image remain.

I'd like to know if there's a way to disable system suspension during mplayer playback, I'm using kde 4.4.2 by AlienBob on my slackware64-current, and powerdevil as the power manager. In powerdevil I've setup the performance profile to suspend the system after 30 minutes with no user interaction, and the presentation profile is setup not to use suspension at all, but I always forget to switch the profile before playing some long video on mplayer and the system goes down after 30 minutes of playback.
Does someone knows a way, a hidden mplayer setting (powerdevil setting would be ok too) that lets me disable suspension only when mplayer is working and nobody is using the system for more than 30 minutes??

I am running Debian 8 with the Xfce Desktop Environment.
I was unhappy with the lock screen on Xfce so I removed xscreensaver and wrote a short custom locking script, which basically involves using i3lock along with some additional commands to make things pretty. I was able to change the default locking behaviour by modifying /usr/bin/xflock4 to run my_lock.sh.
Unfortunately, no lock screen appears whenever I suspend ie after waking the computer from suspension I don't need to type a password in. I would like to force Xfce to lock the screen with my_lock.sh before actually suspending, but I don't know how to do this.
I know that Xfce runs Code: Select allxfce4-session-logout -s when suspending, but xfce4-session-logout is a binary file which I cannot edit.

Anyone noticing intermittent problems with the screensaver not kicking in or the display not sleeping? This is in gnome under F11.I have the Power Management Preferences set to put the display to sleep after 30 minutes of inactivity and gnome screensaver is configured for 5 minutes idle time.On a regular basis, I'll leave my computer come back anda) the screensaver hasn't kicked inorb) the screensaver kicked in, but the power management features didn't kick in to put the display to sleep.It seems to be an intermittent problem and usually it goes away after I restart X, but then at some point it comes back. In the past, I've gotten in the habit of being logged in for weeks/months at a time but I find that I can't go more than a few hours without logging out and back in or else the screen won't go to sleep.

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

Not sure how to explain it.. if I line up my screen perfectly with the light it absorbs just about enough light to make out the outline of the login screen.. seems like the pixels are setting the right colors but the light in the screen isn't turning on if that is possible. If I enter the GRUB menu and load 2.6.35-28-generic it works fine.. the latest doesn't though... so the question.
1) How do I fix this for the latest version?
- or -
2) How do I auto-load the 2.6.35-28-generic version permanently?

I have a huge problem I can't move with. I bought an Asus N61JV laptop and put Ubuntu on it. There was a proprietry software (graphic card booster from nvidia) that asked me to restart the laptop afterwards. I did so, however, the laptop won't boot at all not. It doesn't respond to anyhing, I only hear it working. All I can do is turn it on and off. I'm getting desperate, I've had it for like 2 hours! Please help me, I'm almost crying. I'm not an experienced UNIX user and I totally don't know what to do. It boots until the point where I see Ubuntu writen and then the display like turns off. I can't even put windows there, it dosn't react to f9 or anyhing.

When I booted my computer this morning (lucid lynx 10.04, 2.6.32-21) I found that it showed me a login box, much like normal, but that the text field where I type my username was about a pixel high and disabled. So I couldn't type my username, or password, and had to resort to a tty and links to get here and ask someone for help. I can't find anything on google that looks like people having the same issue and frankly I'm not even sure what is wrong.

I've imported my pictures into Shotwell, but not all of them are showing up. For instance, I have an event (White Water Rafting) where 25 of the 48 pictures got imported correctly. The rest of them were placed in this 2008/12/28 folder and this folder is not visible in Shotwell so I cannot move them into the album.
I can manually move the pictures to their proper dates, but how do I add them to the database? One caveat, the pictures are stored in an accessible /home/SHARE/Pictures/Photo directory so my wife and I can both import into the same place and have access (while the kids have read-only access). I placed the .shotwell directory with all of the database information in /home/SHARE/Pictures/.Shotwell and linked our local .shotwell directory in our home folders to this shared location version.
I am wondering if there is a way to:Force the inclusion of these pictures that are not showing up? Force the database to re-create the thumbnails/scan for particular dates or should I remove (rename) the database, move the files to where they should be and re-import the entire structure (minus the "copy to ... " option)

I have an Apple iBook (ancient I know) and whenever I boot from the Live CD (Kubuntu 10.10) it boots up in 800x600 (as far as I can tell that's what it is). This would be a problem however it simplely leaves a huge black column on the right side and has a partially duplicated desktop below it.
When I go to display settings it won't let me change to a higher resolution (1024x768 is what the iBook natively runs at).
This is an iBook G3.

I've been considering erasing Windows off my hard disk to gain some space, but until then, I want to know that I can do everything I'll want to do.
I've followed many tutorials and threads on the internet, but they never work for me. I added several files to a floppy in Windows, and the floppy works fine in all the Windows computers I've tried. However, when I boot into Ubuntu 10.04, I click on the Floppy Drive in nautilus, but it says "Unable to mount location. No media in drive." From the terminal, it seems that I can mount the floppy (no error message, and the floppy drive clicks), but when I navigate to a folder in /mnt or /media, the folder is empty.

I am running Ubuntu 9.10. When I open my system monitor I get a fuzzy box full of jumbled patterns and colors. Also internet and music notifications in the upper right hand portion of the screen appear in the same way. I am attaching a screenshot of the problem.

I have an Nvidia card and I am using ubuntu 10.04. Before installing the ubuntu nvidia restricted drivers, the boot screen with the ubuntu logo would cover the entire display area of the monitor. But now, after installing the Nvidia driver and fixing the display resolution of the boot screen with the Plymouth fix, the boot screen doesn't expand to fit the entirety of the monitor display area. How can I fix this? There is a good 2 inch off from either side of the display while booting.

I'm using Firefox 3.6.10 for Ubuntu 10.10 with the smooth-scaling ppa (only addons I'm using are Firebug and the Ubuntu modifications pack).Several sites with navigation menus the menu is spread over two lines when it obviously shouldn't be (eg. The Telegraph online, BBC News...) this happens no matter what the zoom level is set to. Chromium renders all these pages normally.

Recently I install ubuntu 10.10 on my Sony Vaio laptop. After the CD boot I always got a black screen, after a week i figured that there's nothing wrong, it's just the screen doesnt show up on my laptop's screen. So I use an external monitor and It showed up as normal.
But I need to have it show up on my laptop's screen. I tried to use "additional driver" to activate latest Nvidia driver but after that even my external monitor doesnt work too. Latest driver doesnt work properly i guess. I did try to install older driver version manually but after I turned of gdm, install driver and reboot, my ubuntu always starts with tty1 command terminal. tried ctrl+alt+7 but it stucked at (checking battery state), startx doesnt help me return to graphical screen too.
I got help from a moderator here but the best result so far is to edit my /etc/default/grub. Change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
Sudo update-grub
after the reboot I have it shows up on my laptop's screen. But it seems low-bit color,a bit grand to me(compared to external monitor, both w/o driver). Anw i checked system/preference>monitor . It showed up that my monitor:unknown. I can't choose other resolutions, refresh rate = 0.
I always know its my widescreen is the problem. I have had a lot of problems dealing wgames/application (on windows) can't work on 16:9 mode. install a stable Nvidia driver
Everything I tried in the past weeks is in here [URL] My laptop is SONY VAIO VPCCW19FX, Nvidia GeForce GT 230M, widescreen monitor

I am posting this under "Desktop Environments" because this does not occur under Unity, nor under KDE (tested with Kubuntu live-CD).
I run Firefox 4.0.1 on Ubuntu 11.04, having installed GNOME 3 via PPA. The following HTML file is not displayed correctly in Firefox:
Code:
<html>

<p>This is <em>italic text</em>.</p>
