Ubuntu :: Screen Sometimes Suddenly Goes Black And Go Low Graphics Mode
Jun 3, 2010
Recently upgraded to 10.04 after countless problems w/ Karmic & already problems with Lucid! The screen sometimes suddenly goes black, then goes into low graphics mode, if I let it, thereby changing screen rez & unless I reboot, I am stuck in this mode. If I don't choose temporary low graphics mode, I must reboot. Many others seem to be experiencing the same problem yet have been offered no solution by the developers. So.
The last few days I have had to reboot my Ubuntu-workstation when the screen suddenly goes black. After some seconds I get a pop-up with the message: Ubuntu is running in low-graphics mode There is some buttons that tells me I can do different things (like reconfiguration ) but whatever I do I end up loosing all windows I worked in earlier. And having to reboot to get back full resolution. I have not found any way to reproduce this behavior. It has happened after being logged in for several days and sometimes just after boot and login when I'm starting an xterm and in all time intervals in between the output of:
What happened was, i used sticonfig to attempt to OC my graphics card, it all seemed to work well, then i put some stress on the card and got a 'black-ish' screen. No matter i though i will boot into text mode (How do you do it normally? The only reason i could was because i crashed my system and could choose recovery mode to then choose text based) and change it back to default and it will all be fine, woo... But apparently you need to be in X server for that command to take effect. ****...........
How do i get into text mode from booting up? How can i fix this?!
I have tried looking in BIOS but there is nothing there. Have i just fried my card? (It was close to max settings - although only on full load for like 1 second) Could booting up normally, and just 'going in blind' work, like opening up terminal with a hotkey and just entering the command from there....
Ubuntu 10.10 PowerColor Radeon HD 5870 Ati catalyst drivers installled
If I let my computer sit for about 10 minutes, I lose all the windows I had open (gnome) and i get a message saying I'm running in low graphics mode. I have to restart X in low graphics mode to get it to work. i can't tell the difference, but as an avid writer, I often feel the need to get up and think about whatever I have open in oowriter.
I just installed Ubuntu on my home desktop computer this morning, and I am having fun exploring this new alternative to Microsoft. I originally tried to install Kubuntu, but after multiple unsuccessful attempts I gave Ubuntu a try and it worked like a charm.
Here's what I did: First, I burned the installation CD. Then I booted from that CD and began the installation process. When the Kubuntu desktop came up, and the icons started to appear, the screen suddenly went black. After that it flashed back and forth between the partially loaded desktop and the black screen. That's as far as I got.
I'm trying to run 10.10 off a USB. On one computer with a nice discrete AMD graphics card, the thing boots fine. On a Dell Latitude e6510 with Intel HD Graphics (the one that comes with a Core i7) I get to the boot screen, the initial text crawl, and then the screen blanks.
Now, I can hear the standard Ubuntu start up noise about 20 seconds later so I know everything is running, just the video driver is not.
I can not do a CD install or anything off the hard drive, only the USB. I'm wondering if anyone knows some edit you can do at the boot menu (using tab) to revert to some graphics safe mode.
Ubuntu has been crashing on boot. I used a recovery mode kernal and went into failsafe mode, upon which point a msgbox told me to switch to low graphics. Then Ubuntu looked completely normal and functional with no problems. To me - an Ubuntu amateur, it seems like a driver problem and that running in failsafe mode will have its setbacks.
just installed 10.10 on my Sony Vaio F laptop. Here's my specs:Processor: Intel Core i7 720QM (1.6 GHz)Memory: 6 GB DDR3 (1333 MHZ)Graphics: NVIDIA GeForce 330M (1 GB VRAM)Hard Drive: 500 GB (7200 rpm)Native Resolution: 1920x1080I shrunk my Windows partition, installed Ubuntu on it's own partition with swap space, and mostly everything went fine. When I booted up, the resolution was set at something like 2048x1536, and it only displayed the top left corner of about 70% of the screen. When I changed to any other resolution, it looked really bad, and the whole screen still wasn't displayed.
Then something popped up telling me to install a driver for my graphics card, so I did, figuring it would fix the problem. When I booted and picked Ubuntu, I was stuck with a black screen. So I restarted and tried booting into safe mode. I got in, and it displayed the whole screen at 800x600. Still no luck in regular mode, however.
I'm running Ubuntu 10.10 on what used to be a windows vista. I bought me a new graphics card today so that I could run dual screen (GeForce210). I saw a guide at [URL] and I followed it.
I typed: sudo apt-get install nvidia-current then I restarted my computer, once again as instructed I typed: sudo nvidia-xconfig then logged out as instructed...
After I logged out the screen went black and I was not able to login. So I restarted my computer. Now when I turn on my computer I am getting this error and it's stopping at it.
fsck from util-linux-n/g 2.17.2 /dev/sda1: clean, 255658/294092280 files, 5031534/117616640 blocks *starting apparmor profiles Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox *setting sensors limits Starting GNUstep distributed object mapper: start-stop-daemon: unable to stat /usr/bin/gdomap/ (no such file or directory) speech-dispatcher disabled: edit /etc/default/speech-dispatcher *starting the winbind daemon winbind
It stops on this screen. I do not want to wipe it but I cannot get it started. I do have an external hard drive and at the moment I am using my Ubuntu disc to "try Ubuntu" I was going to try backing up everything I have but it will not let me access root because I am not logged on to that user, is there anything I can do to get pass this? I've called around and no one is willing to work on my computer since it is now running on Ubuntu 10.10
I have a new sony vaio VPCF11NFX/B with a fresh install of Lucid. I am using a VGA-out to a LCD monitor. It shows up and is recognized. I cannot get video to appear on my laptop monitor. Moreover, when I unplug my external monitor, I cannot boot into ubuntu. It brings me to low graphics mode and I can't do anything from there because half of the screen is missing.
While using Ubuntu I have had few problems and it has generally just worked. One problem I have had is that while using my computer on occasion everything will be stopped and there will a message against a black background telling me the graphics card and screen could not be detected I have several options which are something like.
Run Ubuntu in low graphics mode for one session (which brings me to a normal login) Run Ubuntu from a console (or something like that, it goes to a console) Troubleshoot the error (I'm new to Ubuntu and never tried it) Restart X (I never used it)
I think I missed one or two. "Run Ubuntu in low graphics mode for one session" works for me, but it is still a nuisance that I have to login again. It doesn't happen that often, not everyday at least and happens at random. I could have been using it for over an hour so I wonder why it suddenly can't detect the graphics card or monitor.
When I start ubuntu I get a black screen, I can't do anything, this started when I installed the new driver for my graphics card. I don't know what to do. I have a i7 core (64-bit) and nvidia GTX 260 (twice).
Ubuntu 10.04 installation takes me to a blank (monitor away) screen. I have followed Google searches and forums and have tried all the nomodreset & radeon.setmode=1 stuff on command line and have failed. If you press F6 on the menu and play with the options you would see that half the options do not work even if you select them. Why even have "nonodreset" as an option when it does not do anything? Did the developers not once wonder that having installation that is not based on grapic driver (that is text based or safe mode based) would be the way to go. Go ahead and Google "Ubuntu installation blank screen" and you will see that this is a pretty massive problem.
I also use an HDMI cord (since computer has HDMI support) so this may be contributing to the problem. The same does not occur with my laptop, which runs Nvidia graphics and Ubuntu. I really want this to not happen so I can play my games instantly without restarting a million times. Some games have yet to work (AssaultCube mostly).
I just stupidly changed my graphics resolution in System - Preferences - Startup Manager, now i dont get a login window or anything just a black screen. I also disabled the splash but i assume this just gets rid of the ubuntu loading line thingy?
the weird thing is that the resolution was set to 640x800 or something like that in the Startup Manager as default and the laptop im using (an old Toshiba Amilo P4) supports 1024x768. the System - Preferences - Display menu wouldnt let me change any display settings which is why i was messing about here. I havent got any backed up x org file and only a live usb of super os/ubuntu - no cd or floppy drive.
I have installed the latest debian on a dell optiplex gx260 which has a 82845G chipset and there are some strange problems.The system is configured with autologon as a standard user. Sometimes, after logging on, the screen goes black but if I connect to it with vnc, I get a working desktop. Yesterday I booted it without a display attached to it and now I cannot set it to the right screen resolution anymore (1440 x 900) which was working fine before.
I have googled and searh the forum but cannot find the right information. According to Intel, the latest driver should be in the distro but I cannot find any details about that (version/date). grep Driver /etc/X11/xorg.conf returns
I wanted to update my NVIDIA Drivers from the default to 256 (or whatever the latest is on their site). After the upgrade from their site and installing it through a command line, I've had trouble. For some reason, whenever I boot, I get the Kubuntu boot screen, even though I run plain Ubuntu. Also, after I boot it defaults to low graphics mode, and I have to hit "restart X" to make it run normal. Even then, visual effects won't enable, and games won't run, because apparently the "hardware device cannot be found". My attempts to revert back to old drivers have been unsuccessful; It says it's running the recommended right now, but I still have all these problems.
Just a little background I have a sony vaio VPCZ119X laptop and have been struggling to get all components working under linux especially the intel graphics. I saw that once I upgraded to the latest available kernel release which currently is 2.6.37 rc7. The intel graphics is working, but sometimes when I boot I get a blank/black screen but seems to be lit up. All other functions seem working so for example I am able to login etc just that I dont see anything on the screen.
I have tried the following so far to identify the issue or isolate it:
- Switching to the console screens has no effect, still the black / blank screen.
- Restarting the system does not always immediately get the screen working, sometimes it takes a couple of reboots before the screen is available
- I have a switchable graphics with nVidia I never get this problem when I use the nvidia driver
- I have tried closing the lid etc as suggested in the below post without any change in output, will try further as there are other options available as well The "Black Screen" on Boot I see one difference between both the Xorg log files but I am not able to reason out why this happens hence I will just supply the files here and try not to theorize.
Xorg.0.log - This was the log output when I got the X display working Xorg.o.log.old - This was the log output when the X display was black/blank Also to highlight that I am using the latest kernel release that is still being tested I guess so maybe it is also a bug in the kernel?
I'm using openSUSE 11.4 on a HP Pavilion laptop, and it was working fine until last week or so. A zypper update seems to have upgraded to a package with a nasty bug though: it now boots into a black screen, instead of showing kdm.And the only option after that is to forcefully shut down the machine;ither Ctrl+Alt+F1 nor Ctrl+Backspace nor Ctrl+Alt+Del does anything. Not sure if this means the kernel hangs,or just that X blocks all keyboard input as well.The issue with powering off with the hardware button is that I don't get full log files (especially kdm.log) so it's a bit hard to investigate...I have tried many things, here are the results:
* Default radeon driver + kdm = black screen * nomodeset + radeonhd driver + kdm = black screen [driver doesn't support HD4200 anyway] * nomodeset + radeon driver explicitely requested + kdm = black screen
I have an old machine running Ubuntu 9.10 and XP.t is a P4 and Nvidia FX5200 card.Yesterday all of a sudden the screen started flashing black, the same type as when you install new graphics drivers and the resolution is changing. Only here it keeps happening over and over, the mouse isn't usable fully, the icons and menus are distorted, and I basically can't do anything.
I ended up reinstalling 9.10 and everything was working fine until I installed EnvyNG to get my nVidia drivers. It required a restart, and once I logged in the same thing started happening. So I said screw this, and installed 8.04. Yet even in 8.04, once I used EnvyNG to install the drivers, the same thing happened.A few other detailsP works fine, although one time a similar thing happened on XP (not as bad), and was fixed with a reboot.- This PC runs through a KVM switch, but I connected it directly and the same thing happens.I've found no help via Google. Sounds like a possible hardware problem, but it seems to work fine in XP and only acts up in Ubuntu once I install drivers.
I'm having no end of problems trying to get 10.04 onto my older Toshiba Satellite A50 laptop that I use as a spare laptop round the house. The laptop previously dual booted with XP and Xubuntu fine. I wanted to give Lubuntu a go to see if it's performance was better on this older hardware. When installing I got the black screen of death, and also got the same problem with the Xubuntu CD. Research pointed me in the way of this article: [URL] I was able to boot the Lubuntu Live CD using the instructions outlined in method A.
Once installed however I rebooted and Grub seemed to be knackered. Just sent me to a recovery console of which I had no idea what to do. As I could no longer boot into Windows either I reinstalled Xubuntu 9.10 and all was fine. I decided yesterday to give it another bash this time connecting to my wireless from the live cd hoping it would download an update to fix this problem. Nadda, Grub this time did show and I was able to boot into XP, but upon picking my Linux distro I now get an unrecognised device error with a long string of charachters and then it dumps be back into the grub menu, choosing the recovery mode version does the same thing.
It has been a few days I'm struggling to install Kubuntu 10.10 on my computer. I started with the normal CD, burnt it and boot the computer. Halfway through the graphical installer, I got a black screen and system froze up. I tried several things (including running the installer with nomodest and single options) but didn't help.
Then I downloaded the alternate CD and started to install in the text mode. I could get passed installing the kernel and programs but right after adding a user/password, the text installer crashed with a black screen and system froze!
Now, I already have Windows 7 64 bits on this computer and have done all kinds of memory/hardware tests on it and it works fine. The CPU, GPU and the case is well ventilated so nothing is overheating. I also run heavy loads on Windows (MATLAB, Chess engine tournaments) for hours and hours and never had a crash. So I guess the hardware is fine.
Here are the specs of the system if it can help:
CPU: i7 950 GPU: ATI HD5870 (model Gigabyte GV-R587UD-1GD) RAM: 12 GB DDR-1666 Motherboard: Gigabyte GA-X58A-UD3R (rev. 2.0) Optical drive: Liteon ihbs112 USB Mouse and Keyboard
Windows is installed on a SSD and I have 2x 2.0TB hard disks for data. Kubunto, however was being installed on a separate and dedicated 200GB hard disk. During installation process I format and partition this drive. I didn't disconnect/disable the other drives. In BIOS, all SATA controllers are set to run in AHCI mode.
My primary suspect is the graphics card. However, why it would ever crash even in the text mode? Although it works fine in Windows even with heavy gaming so graphics card is itself stable.
I recently came to Debian. As I have an ati card, I tried the proprietary drivers first, but then came back to radeon (open-source). In the process, I think I may have broke my xorg.conf . Sometimes, when the monitor goes into sleep mode, when I came back, the screen remains black (sometimes I see just the cursor).
Here is my xorg.conf # NOXORGCONFEXISTED: No X.org configuration file existed when this backup was created.
Also, I have lots of backups in my X11 folder, like xorg.conf.fglrx-3, xorg.conf.original-1, or backup.xorg.conf. Is it safe to remove them? What should I do about the main xorg.conf?
F9 has been running great since it came out. I read that one should install F10 before F11 so I did install F10! Everything went great.
(1) Then I tried to install the F11 iso dvd. After the "anaconda started" message at the bottom of a blue screen, the screen went blank and occasionally the message would appear: "cannot display this mode 2:dvi-d". Thinking the monitor had gone into power save, I hit many keys and moved the mouse to no avail.
I gave up! BTW I had checked all media CDs for errors.
(2) then working under F10, a little message appeared from the lower right of the screen asking if I wanted to upgrade to F11.
I accepted and again "cannot display this mode 2:dvi-d" on a black screen after anaconda started on a blue screen. This time no ISO DVD F11. I've never seen such an error message in 11 years (off and on) of using Linux. HD Disk activity was showing on the disk activity light so I let it run all night and part of today. I hit a bunch of keys and moved the mouse and the blue screen returned saying all was done and restarting.
After restart, I seem to have F11 installed. I did a yum update and got some more F11 updates. On the grub screen, the only F11 kernel was the PAE kernel which I selected and got:
Does F11 have any F11 kernels? BTW running >setup (hd0,0) under F10 grub ruined my XP prof OS on scsi 0 so I reloaded XP Prof from scratch.
(1) what is this "cannot display this mode 2:dvi-d"?
(2) Now I cannot boot to Fedora 11 and all the advice on how to reinstall grub has failed failed. Did a rescue and chroot /mnt/sysimage and the fdisk -l
Now XP Prof seems to be on /dev/sdc and Fedora on /dev/sdd. What do I do? In the meantime I have retreated to Fedora 10.
I cannot install FC11 or FC10 on my Dell XPS One/A2420 machine. Every time I tried to install the Linux operating system, the screen goes black and the computer goes no response. It seems to have something to do with the video card--Intel GMA X4500HD Graphics.
I am running on ubuntu 10.04 and using the latest nvidia driver. What I experience is a random black screen, my monitor goes dead and won't turn back on till I hardboot. I had this issue on windows and solved it by downloading rivatuner and telling it to force my 9700m into staying in 3d performance mode at all times. I know it has nothing to do with temps or anything like that. All I need to know is how I can duplicate what I did with rivatuner on windows
Ever since the problem with Flash started up a few days ago, (Videos Lagging/jumpy/jerky horridly.) I decided to finally switch from 9.10 to 10.04...all was going well until a few minutes ago while I was browsing themes and running Konversation, the skin flickered black/green a few times then white vertical lines started appearing down from the top of the screen to about the middle, (Almost looked like the teeth on a haircomb). I had to then shutdown and restart. What id like to know is are the two connected (My earlier flash problem and this) or how I can fix it, so far it hasn't happened again but I'm starting to worry, I've never had problems with Ubuntu until a few weeks ago.
