Ubuntu :: PC Resumes Inmediately To Blank Screen After 'suspend'?
Jun 17, 2011
It seems 'suspend' (to RAM) does not work in my PC. After pressing the button this is what happens:1- PC switches off monitor and hard drive2- PC resumes hard drive activity inmediately after3- PC switches on monitor to a blank screenI can't bring any image in the monitor, I don't know if the keyboard works at allThe typical commands to bring a prompt or kill the X-server are not working.Pressing & releasing the power button doesn't change things, either.My only 'solution' is to press the power button for a while to completely switch off the computer and then reboot it.

Title says it all. I close my laptop lid. It goes into suspend mode. I open it up again, the computer powers up... and I see a black blank screen. No key combinations seems to bring anything back.

Up until a couple days ago, my computer had no problems suspending to ram. However, now when I suspend, and later hit a key on the keyboard (usually space) to resume, all I see is an illuminated black screen. I can't even open a tty via Ctrl+Alt+F1. I can however ssh into the machine.he only possibility I can think of is that I am no longer running kdm. I just use "startx" to star an openbox-session.

I'm using a dell latitude d630 with an nvidia quadro 135M card. I'm able to suspend without any problems while running the X server. If I try to suspend on console without the X server running, the laptop wakes up to a blank screen. The screen remains blank and my only resort is to type sudo halt (with the screen off).I'm using the proprietary nvidia driver with the nvidia-kernel package on testing.

I am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.

When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.

Ubuntu Karmic Koala
2.39 GB of RAM

Is there a known problem with the Lubuntu 10.10 image here? I have downloaded it to two different computers, then burned the images to two different blank CD's (different brands) and neither loads. Both only get as far as the Lubuntu menu, once ENTER is pressed at that point to load the LiveCD, a blank screen eventually appears with a flashing cursor at the upper left of the screen, that's it. They were both burned using the slowest burn speeds available.

The day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.

FYI -The CD works fine as I have tested it on other machines.The version I am trying is xubuntu x86 (although I have tried ubuntu 10.04 x86 with similar results).I can Alt+Ctrl+F1 fine and get to the cmd prompt

I fixed this issue on 10.04, but just recently (1 hour ago) upgraded to 10.10 and am having the same issue. Machine boots fine, but the screen is blank for most of the boot, and plymouth is up for about a half second before I get to the login screen.I've tried searching the threads, but for the life of me I can't find the solution and can't remember what I did to fix it on Lucid.

like any other Linux newb, I came to Ubuntu because my Windows crashed one time too many. And I chose Ubuntu because "it just works". But these past few days that hasn't been true. I'm posting this from a netbook with Ubuntu, and am having no problems whatsoever, but normally I use an Acer Aspire 5920G laptop. I'll include the specs as written on the sticker:
* Intel Core 2 Duo processor T5250 (1.5GHz etc)
* Up to 1024 MB Nvidia Geforce 8600M GS Turbocache
* 2 GB DDR2
Let me know if you need more details, and I'll add them later. Now, what happened was I clicked "hibernate" while leaving Firefox open. (I've done this hundreds of times, no problem) And when I went to turn it back on the next day there were weird graphical glitches in the loading screen, and it booted to the "tty1" prompt screen. I did a lot of googling and found quite a few posts about it, but the solutions either didn't work, or I didn't understand them. After trying several different suggestions from this forum and others, I managed to delete the graphics drivers. That enabled me to boot in low graphics mode, and naturally, I tried a whole bunch of things to make it work properly again. That only made it worse. Now it went straight from the loading screen to just blanking out and turning the display off. So, I tried new things. Over and over. The weird thing is even when I disconnected my harddrive and ran from a Live USB, the problem persisted. Could there be an issue with the graphics card itself? Anyway, after reconnecting the harddrive I tried to boot again. And it suddenly worked. Even HDMI to my bigger screen worked.

I have been running 10.04 quite successfully, when I upgraded to 10.10, I have a problem with the newer kernels. If I let it boot into the latest one 2.6.35-23, I get the Ubuntu 10.10 splash screen for a second then a blank screen, same with 2.6.35-22. I have to run with 32-25 to get it to load the gui.
I have an AMD Sempron 2800, 1.6GHz pc, but I'm not sure if it's running 64bit.

I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?

Recently when emailing my resume in openoffice .doc format some recipients are complaining that it is unreadable. This is bad for obvious reasons. I have no idea what is going on in the ms windows/office world. I run linux exclusively.
If I can't use openoffice formatted resumes, does anyone have suggestions for sending a resume that most recipients can read?

I have the most bizarre problem that started with 10.04. Up until 10.04 I had zero problems with my setup. I am convinced this has something to do with NVIDIA 7100GS and 10.04.
Here is the problem in a nutshell. I have my home desktop, which I upgraded to 10.04 from 9.10. Everything went just fine except when it booted up and I logged in, the video "shut off", the computer "hung" for about 10 seconds, then came back. I'm able to use it for about 10 seconds then the same thing happens. Video blanks, system hangs, comes back.
I've tried turning off compiz, no effect. I've tried nvidia-current along with other versions (including the one from the website) and they ALL have the same problem. I know it's not a hardware issue as I can boot the live CD just fine. I also upgraded to 10.04.1 and that worked fine until I installed the nvidia drivers. Here is what I dont understand either. I did a apt-get remove --purge nvidia* and the problem still existed after that.
Something is seriously wonky. I REALLY don't want to re-install the entire box. Now, here is something else that doesnt make sense. I have 10.04 installed on my work box with a Nvidia 9800 graphics card and I have no issues at all.

I recently upgraded my debian system from jessie to stretch. Before then, I was mostly using hibernation instead of shutting off the laptop, to allow myself to get back faster to work the next day. Since my upgrade, though, it is impossible for me to resume from hibernation: after the normal boot sequence and the passphrase to decrypt my lvm partition, when it has loaded the information from RAM the screen just stays with a blinking "_" (underscore) in the top left corner.
I have hibernate and uswsusp packages installed. I also installed tuxonice-userui package to do some tests with the hibernate-ram and hibernate-disk commands. While using hibernate-disk (hibernate-ram didn't work, because "s2ram: unknown machine"), my system hibernates correctly, and I saw that during resume it was correctly loading everything from swap and then going back to the "underscore screen", confirming that the resume problem was happening after loading data from swap.
I tried booting using the recovery kernel in grub. For a time it worked, but today I didn't get the chance to make it work. The only solution was for me to boot my kernel by adding the "noresume" option to it, thus forcing it to restart.

I upgraded to latest 10.04 live x64 desktop today. Clean, fresh install.Before I was using 9.04 and had the same issue at first.I don't want the password lock screen when resuming from suspend.I disabled everything, lock in screensaver settings, all lock entries in gconf-editor. I also tried setting LOCK_SCREEN in /etc/default/acpi-support to false.Nothing helps Is this maybe a bug, since it's still beta? I don't know what else to do

When I close my laptop lid (it goes into suspend mode). When I open it again, I can't see anything but a black screen. I have to reset the computer manually to accessUbuntu again.On a related note probably.. for 'some' screensavers, when I click to re-access my desktop, the screensaver freezes, but I can't see the unlock dialogue. I can however still type my password and it will unlock, I just can't see what I'm doing

When ever I choose suspend to shutdown the hard drive slows and the picture on the screen freezes. The mouse and kb are disabled and the cpu fan keeps running. My hardware in in my sig below I have turned off automaitic updates straight after installing from disc as the last time I had it switched on after a few updates I got repeated ata drive read errors and the pc would freeze for a while being unable to read from the hdd. I have run wd diagnostics on the drive and it works fine. To fix this problem I did a clean install after messing round for 3 days and achieving nothing. I have an arch partition that works fine as well although I have not attempted to get suspend working with it. ( hal error) I have read a few thread on the net and tried entering the swap disks uuid into grub.

I've got Karmic installed on an HP 6930p, and with relatively little intervention, all hardware has been supported beautifully. I'm using the ATI driver for graphics. Battery life increased dramatically after an update a couple of months ago. However, occasionally (1 in 8 times maybe), the screen is black when waking from suspend. Disk wakes, etc, but the screen is off. Trying to re-suspend with fn key doesn't work. Ctrl-alt-f key combos don't work. I have to hold the pwr button down.

All is in the thread title. When I log back in after suspend or hibernate I get a lot of flickering on the screen. I noticed (I think) that it calms down a bit when streaming video from the net, if that gives any clue...
I'm using a dual boot with Vista basic/lucid lynx on an Acer Aspire 5100 laptop.

Ok so I'm still a bit of a Ubuntu n00b and I just installed 10.04 on my new laptop (Asus U35F) and it's working pretty well except for one problem.. Every time the laptop goes to sleep/suspends/hibernates, when I try to resume it again it hangs. So I end up seeing the screen to re-log in and I can usually move my mouse around and start typing my password in and all of that for maybe a second, but after that it just freezes!
Especially since right now Ubuntu is the only operating system I have running, and since I use this in school and need to conserve battery as much as possible so it stays running through 6 hours of class, I really need to get this fixed up soon..

I have installed Ubuntu 11.04 along side windows 7 ultimate. But the problem is as soon as I switch on my computer. There is only a blank screen with my TFT screen displaying a msg "Out of Range"
Then suddenly Ubuntu loads without showing any option to load windows 7.

I recently upgraded from Lucid to Maverick I can't seem to disable screen lock after resume from suspend. It's a minor annoyance, but still a considerable annoyance to have to enter my password every time the computer wakes up.
I've thusfar
1 - changed screensaver preferences to not lock
2 - set the gnome_keyring_hibernate, gnome_keyring_suspend, hibernate, and suspend, values all to false in gconf-editor
3 - commented out the line LOCK_SCREEN=true in /etc/default/acpi-support
BUT am still being prompted for a password every time the computer wakes up from suspend. I'm stumped, what could I be forgetting?

I'm using Ubuntu 11.04 64bit. Mainboard Gigabyte GA-H55M-S2V. My LCD is a HDTV monitor which is plugged to onboard graphic card.
I don't know what happen with my Ubuntu. It sometimes goes black when I try to wake my PC when it's suspended previously. The screen is black, but I still can move mouse cursor. I also can do blindly click on stuff on screen (I could play a song last time by clicking randomly). This problem also happens sometimes when I switch back to PC from TV (My LCD is a HDTV monitor).
The only action I can do when it happened is reset my PC.

I would like to disable the login screen when the computer returns from suspension and hibernation, so that it will automatically log me back in. I am using Ubuntu 9.10.When I come back from suspension, for some reason, my key board does not work in the login screen and I cannot type my password.

I've been away from Kubuntu for a while but came back when Kubuntu 11.04 was released because it's awesome. I have a newer laptop since then, a Latitude E6410 with Intel graphics and 8GB of RAM. Everything works great, except......Sometimes when I resume from suspend to RAM, the screen flickers with thin white lines across the screen. I can switch to a tty and reboot it from there, but I'm unable to use KDE until I reboot. A lot of times resuming from suspend works without issue, but sometimes this problem occurs. I haven't figured out exactly what triggers it. In fact, the most recent time it happened, I didn't even have an application open.
I would like to figure this out because I use suspend a lot. I rarely turn off my laptop unless an update requires me to. I prefer to be able to close my lid and resume whatever I was working on later, but with this glitch I cannot trust it to do that.

I am having some pain with my new Squeeze installation, I am not sure if I am asking to much of it or it is an easy fix.
Firstly my system is laptop which I regularly plug a second monitor into. The video adaptor is an ATI HD4550 mobile.
My problem is that when ever suspend or hibernate my system, and even sometime when I boot up the screen(s) are just blank, although sometime they don't, it always happens if I suspend by closing the lid of my laptop, and only sometime happend with through Gnome is go ->System->Shutdown->Suspend. This is really annoying.
Another issue which I think is connected is that as I said I have a second monitor (most of the time) and when I boot up then it works until I log in, then a message pops up say the configuration can not be applied and it revert to Mirror mode or it does this thing where it places the second screen inside (virtually) the built in Laptop panel, it will not let me fix this through the monitors dialog just displaying the same message. I can fix this by doing
invoke-rc.d gmd3 restart
This gets as far as killing Gnome them it prints an error the to console, at which point Imopen a new terminal by ctrl+alt+f2 and
invoke-rc.d gmd3 stop
invoke-rc.d gmd3 start
then it works fine and even remember that I set the secondary screen to be the primary monitor through xrandr.
I tried install fgrlx drivers instead but it didn't really fix the issue, so I removed them.
