Ubuntu Installation :: Blank Screen: 10.04, ATI Radeon 9550 / X Tries To Load Screen Just Goes Blank?

May 9, 2010

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.

Ubuntu :: Screen Frozen On Resuming From Hibernation

Apr 15, 2011

I bought a laptop from ZaReason (zareason.com) with Ubuntu already installed. I am currently running 10.10. The machine has worked great but recently has had problems coming back from hibernation. This is a new problem and did not seem to coincide with an update or new software. When I try to "wake up" my laptop, it shows a bunch of text (I am not that computer-literate, so I don't understand the text) and becomes unresponsive. I will insert an image of my screen when it is frozen: DSCF7055.jpg

Ubuntu :: Laptop Standby: Wireless Tries To Connect While On Standby

Jun 27, 2010

Running Ubuntu 10.04 on a dual-boot Windows 7 laptop.

On "suspend," the wireless card appears to close connections correctly. Then, >15 minutes later, the laptop's wifi LED lights up and the laptop generates heat.

The computer should be on standby, but instead it's waking itself up and running down the battery.

Are there any programs that might be failing to suspend for sleep? Are there any settings to prevent the wifi card from waking the computer?

I only noticed this because the laptop was getting hot and the battery was wearing down.

Ubuntu :: Sometimes When Resuming From Suspend - Screen Flickers With White Lines

May 29, 2011

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.

Ubuntu :: Asking For Password On Standby Screen?

Apr 14, 2010

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.

Ubuntu :: Display - Black Screen Instead Of Standby

Mar 21, 2010

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.

Ubuntu :: 10.04 Lucid Nvidia Driver Second Screen In Standby?

May 1, 2010

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?

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.

Ubuntu Security :: Encrypting Swap Space Breaks Standby/lock Screen?

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?

Ubuntu :: Screen Keeps Going Blank/flashing Blank?

May 17, 2010

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 Installation :: Lucid (monitor Switches To Standby) - Screen Goes Black With A Flashing Cursor Then Changes Back To Purple

May 5, 2010

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.

Ubuntu Installation :: 10.10 Image Not Loading - Flash Screen On Blank Screen

Dec 26, 2010

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.

Ubuntu :: (Grub - Windows 7 - Unknown Filesystem) - Screen Goes Blank And Screen On-button Begins To Blink

Jan 26, 2011

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.

Ubuntu :: Screen Goes Blank Or Boots To Tty1 After Loading Screen?

Apr 15, 2011

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.

Ubuntu Installation :: Get The 10.10 Splash Screen For A Second Then A Blank Screen?

Dec 22, 2010

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.

Ubuntu Installation :: Freeze/Blank Screen After Screen Off 11.04?

May 4, 2011

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?

Ubuntu :: Can't Log In - Blank Screen

Jul 17, 2010

My problem is that I can't log in to Ubuntu, as you've already seen in the title. Here's what's happening:

I turn on the computer. I see the GRUB. I press Enter. I see a blinking underscore (_) as if i was in a terminal. The underscore disappears and I can see my cursor, but nothing else. I can move the cursor, but that's all I can do.

I've seen some similar problem here on the forums, but he could log in, he just couldn't see the screen.roblem!

Ubuntu :: Blank Screen On Ctl-alt-F1?

May 1, 2011

OS: Ubuntu 10.04 LTS, kernel 2.6.32-31-generic. All updates are current.
Configuration -CPU: Intel Core i5-2500K, quad core 3.30GHz
Memory: 16GB RAM (10% used), 20GB swap-space (0% used)
Video: Two ASUS EAH5450 Silent cards, each with ATI Radeon HD-5450 GPU and 512 MB
Monitors: Sceptre 22", 1680x1050; both connected to one video card. The second video card has no monitors connected at this time.
ATI/AMD proprietary FGLRX driverLSPCI output -

[Code].....

The PC boots up normally into Gnome desktop environment. When I hit ctl-alt-[F1-F6], -The screens blank out. One screen gets no video signal, as evidenced by a blinking power light The other screen is completely blank (not even a blinking cursor) If I hit ctl-alt-F7, I get the Gnome desktop back. I have been able to determine that even if the screen is blank, and appears completely dead, the system processes my keystrokes. For example, if I pretend that I am at the log-in screen and type <username> <enter>, then <password><enter>, then 'xinit -fg white -bg blue -- :1 vt8'<enter>, the PC switches to virtual terminal 8, and shows a shell window. From that point onwards, my keyboard entries show up in white-on-blue characters, and the behavior of this shell window is perfectly normal. I can log into another Linux box using ssh, start a Gnome / KDE / XFCE4 / LXDE session and work on the machine normally; or start another X-session and a desktop environment of my choice. My guess is, the console is invoked perfectly well; it is set to display black-on-black characters.

What I Am Looking For:Confirm if my guess about black-on-black console is valid.
Suggest how I could get a screen showing white characters on black (or indeed, any combination I could read)

I selected the option Ubuntu, Linux 2.6.31-19-generic as I figured this is what normally loads without being prompted in the grub menu, but after this I got the ubuntu logo for a few seconds then my screen goes blank. My laptop is a hp510.

Ubuntu :: Screen Is Blank / Add A Monitor?

Feb 23, 2010

I'm a newbie so apologies if there is a trivial answer to this.

I (maybe somewhat rashly) tried to connect my tv to my laptop (Dell Latitude D400) running Ubuntu 9.10.

I plugged in the cable, went to the System>Display menu, where it had detected the model and make of tv (Samsung 19" LCD) (I think the resolution was 1650 x 1050 or similar). I clicked the box to activate the second monitor with the "Virtual resolution" adjusted. It told me to log out then log back in.

I accordingly logged out but then couldn't log back in. It had evidently changed the resolution not only on the 2nd monitor but also on the laptop monitor. A box was visible on screen but completely illegible/unclear since the laptop monitor couldn't display that resolution.

After a few restarts and button pushes it is now restarting at a terminal (I enter my username/password at a command prompt on an otherwise blank screen rather than the graphical interface loading up).

Question: are there any commands that could change the resolution back to its original settings then restart the Ubuntu graphic interface? Some thing similar to the "load with last known good configuration settings" option in Windows maybe.

Ubuntu :: Not Starting - Blank Screen ?

Apr 23, 2010

My ubuntu isn't starting up today. I can't remember anything unusual happening last night, not even a standard system update.

It presents me with the Grub loader, screen goes blank, and that's as much as I get. I have gone into a recovery mode through the grub loader, and that gives me a bit more info, but I don't know what to do with the information it is giving me.

It says: Gave up waiting for root device. common problems (etc) ALERT! /dev/disk/by-uuid/<long name> does not exist. Dropping to a shell.

It is right - the /dev/disk/.... does not exist. A different file with an equally long filename does exist
