Ubuntu :: Monitor Display After Login Breaks Up Rendering The Computer Unusable
Mar 26, 2010
I have a rather odd problem with a machine. Up until the user logs in everything is fine, but as soon as they log in the display breaks up rendering the computer unusable. Booting from CD is ok, but the monitor is not detected.
I recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.
I run Ubuntu on a MacBook Pro with an external monitor connected. But currently the external monitor only works with one user account. The External gets no signal and the laptop display is used on the login page. Is there any way of having the login page and possibly startup displayed on the external at all times for all accounts.

I just downloaded Open SuSE Linux 11.4 and installing it on a Vaio 2.8ghz Computer. While loading everything went well, but when I loged backon my Monitor Flashes about every 20 seconds, just for about 3 seconds. I am using a GForce 2200 Video card.What I need to know is their anyone who can tell me why this is happeining and how to fix it. I have used Open SuSE 10.3 on another machine and have never had this problem.
When I start my system its getting booted through LAN and it showing login screen after I login it shows only black screen. Whether is may by Video adapter problem?
This problem came after I run a Perl portscan program, this script just scan all the ports from 0 to 65535 and reports which port is open and closed.
I've just installed BitDefender on my 10.04 netbook, updated and activated it, completed a scan, and found Backdoor.Generic.284566 The thing is, it won't let me delete/quarantine the nasty. BitDefender does give me a warning about my screen resolution being too low (800x600), i believe this may be the problem. The option buttons are not visible on the screen, therefore I cannot use the program properly.(i tried the max resolution 1024x600, but to no avail )
I have noticed they sell digital writing tablets that have the ability to show the pen strokes both on the tablet's display and on the computer's monitor at the same time, and I think they are called LCD digital tablets and they serve as both a second computer monitor AND a writing tablet combined in one, such as the Wacom Cintiq, and must be connected both by USB as well as with a VGA/DVI port, and you have the ability to open up a drawing application directly from the tablet such as Paint where you can draw or write on the tablet's display. And you can see what you are writing on the tablet's display. Then you save the results to a JPEG file, for example.
But I do not want a digtal tablet quite as elaborate as that. I am looking for something similar to the credit card terminals used in stores where you can sign your name directly on the display after swiping your credit card, and you can see what you are writing as you write. Then your signature shows up on a paper receipt later. Do they make digital tablets like that for the home user, and if they do, would they have to hook up to the VGA/DVI port on your video card? What are they called and where can I get one?
I've searched several online stores but they do not say if you can see what you are writing on the tablet's display. I already have a Wacom tablet in Linux but you can not see what you are writing on the tablet. I have to keep looking up at my computer's monitor to see what I am writing and proficiency is reduced as a result. And again, I do not want a tablet as elaborate as I described in my first paragraph. I want something simplier, such as the type used at a credit card terminal.
I would prefer to be able to use the rpmfusion nvidia driver instead of the closed driver but when I try it, KDE4 runs fine for a while but then the whole display starts blinking and the cpu % goes to 99% for XMy PC is Fedora 12 x86_64, the video card is a XFX 8800GT[URL]1) installed the kmod-nvidia-190.53-1.fc12.1.x86_64 and dependencies2) blocked nouveau with rdblacklist=nouveau in grub.conf, 3) Ran: setsebool -P allow_execstack on4) fixed the xorg.conf (I had to move my old xorg.conf out of the way and merged my DontZap option back in) 5) rebootedI did not yum remove the nouveau driver,.... didn't seem necessary.My desktop will run for a while but inevitably starts flashing uncontrollably. I can't even ssh to it to run init 3 to kill X (I can ssh to it but for some reason I can't su to root to kill X).
I have an iBook which I just installed karmic after several tries due to issue beyond this thread. The specs of the are listed here: [URL].. ,but basically it boils down to the following:
* introduced 2003.10.22 at $1,099; replaced by 1.07 GHz model 2004.04.19 * requires Mac OS X 10.3 through 10.4.x, 10.5 not officially supported * CPU: 800 MHz G4 * bus: 133 MHz * performance:
I'm new to Fedora/Linux trying it out because I'm becoming hacked off with Windows taking so much time to do anything. The problem I have is that every now and again the computer slows down so drastically that the mouse movements are jerky, response to clicks/key inputs take about 2-3 mins to get a response and the only solution is to press and hold the power button. I'm running a Packard Bell Dot M/U. It has mobile celeron 1.3GHz 64 bit, 3GB ram. Intel wi-fi, atheros LAN (i think), HDMI output. I believe that it is v similar to an Acer Aspire 1410 (but not 100% same).
I am currently running squeeze with the 2.6.32-trunk amd64 kernel.
If I close the laptop lid the screen will not turn back on and the laptop becomes unresponsive. The only way to get it functioning again is to hold the power button down until it dies.
I have Lenovo T410 with NVIDIA NVS 3100m running nouveau driver/F13. When I updated to the latest kernel, the display goes blank when booting and remains blank. I can ssh to the machine, so - it appears to be an X/display issue. All else seems to be working normally, and I didn't spot anything of interest in the logs - but perhaps I don't know what to look for.
Also, it appears to be an issue in the kernel package rather than in the nouveau driver package. I can still boot the former kernel successfully - even with the new driver files.
The previous kernel version was the version of the kernel that is provided with the initial F13 install.
I start, e.g. Lightsmark having set up Vsync, so that video would be smooth and not tear. It shows 60FPS - just as monitor refresh rate - 60Hz, but as i see, video is still jerky when there are many objects rendered. What could be the reason, i wonder? How could i investigate this?My video card is nvidia, Vsync etc. are set up via nvidia-settings.
When Karmic came along, I upgraded and it was possible for the first time to get a dual monitor display working using only the GUI apps supplied. (I think I used screen resolution) It worked out of the box and took no time whatsoever.
I had a dual monitor set up working with 2 1024 x 768 monitors, with a desktop spanning both, and a background picture doing the same.
The Lucid update has just spectacularly broken this, along with a large number of desktop type changes that were unwanted.
The version of Ubuntu was the usual vanilla, but with enough K stuff installed to make K3b work. The card is a Radeon 9250SE.
Give up and re-install Karmic? Wait for some sort of upgrade to allow either Monitors or Multiple Screens to work - the option to remove cloning is greyed out in one and unticking clone in the other does nothing? Try some other distro?
Does anyone know of a decision to remove any functionality from Lucid that existed in Karmic? Is there any useful background to this that is perhaps not obvious?
A few days ago, I did a clean install of Ubuntu 10.10 onto a Mac. I dual-installed with Mac OS, and everything appeared to be going very smoothly. until I connected to an external monitor (a video beamer I use in my classroom). This led to:
a) the external monitor apparently being considered the primary monitor, and
b) compiz effects being disabled.
I addressed (a) by modifying the file monitors.xml in [me]/.config. (Before that. I had created a startup entry xrandr --output LVDS1 --primary. That also seemed to work; after changing monitors.xml, however, I disabled that startup entry, as it now appeared redundant to me.) Generally and for all I can tell, my actual computer screen is now correctly identified as the primary monitor -- from the moment I log in, at least. The log-in screen itself, though, appears on the external monitor, or not at all when that monitor is turned off.
This is the content of my monitors.xml file: I have not found any solution for (b): when I physically unplug the external monitor and reboot, compiz will run again; but once I plug in the external monitor, it won't.
I installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.
Booted puppy 4.12 off usb many many times have i booted puppy and other distros this has never happened I get to part where you choose xorg or xvesa I chose xvesa, as usual my monitor makes a "click" noise as if its been turned off but it doesn't turn off default puppy xvesa is 800x600 so i changed it to 1024x768 as usual after messing around I reboot into my ubuntu-9.04 install and my desktop is 800x600! I reboot into my SalixOS install and my desktop is 800x600! every system I boot into is this way! even live cd's! the PC is a Emachines with everything Nvidia mx4000 geforce and old 15inch vga monitor how do I output graphics card and monitor info?
Here is the xorg.conf every distro changed too
Code:
If I install the nvidia drivers in ubuntu/debian, only then can I get 1024x768 resolution
I'm trying to install Atheros AR9485 wireless card driver on debian, and I had no luck.
I followed this [URL] .... to install backports kernel version. The wireless card worked, however, intel display driver displayed the color in the wrong way.
Red pixels are green, and green are yellow. It was displayed like when someone try to connect a PAL system to a TV that supports only NTSC.
I downloaded an FLV video and placed an extra MP3 file over it. Two files. Total: 30 MBI experimented with about seven rendering containers, and QuickTime renderer was the only rendering container that didn't result in sped-up/compressed video or correct rendering for just fifteen seconds.How in the name of all that is holy did this rendering end up with 570 extra MB?
How can i change that login window's font rendering, i mean that screen which you can select user and type password. Is anybody have the experience for tweaking gnome login font or background image?
if i run chromium with --enable-gpu-rendering flag chromium's display looks like it's shattered into thousands of pieces and I can't understand a thing. This doesn't happens if I have a previous instance of chromium opened in the usual way, without any flag. In this case if I open another chromium window with the --enable-gpu-rendering flag it's display looks ok, but I can't figure out what's the problem and how could this be fixed if there's solution for it of course.
I just installed a test Natty VirtualBox server from the "mini" iso. After doing that the normal boot always ends with a blank screen and cannot login. The recovery boot option does work normally. After much digging around and various tests I found that the "splash quiet" boot options cause this issue.
I removed them from the /etc/defaults/grub file and ran update-grub. Next boot the login screen came up after as normal. It seems when the splash flashes that purple screen with the Ubuntu 11.04 message it is breaking something and does not get back out of some graphics mode.
This is in a VirtualBox window and I noticed that vesa framebuffers seem to be used by default in grub now. I never had this issue in previous releases and I'm just wondering if others have seen this and if there is a better fix than disabling splash. I don't mind having it disabled as this is a server install anyway and I'm fine with seeing debug messages during boot. If other have seen this then perhaps it needs to be logged as a bug?
I recently downloaded Frets On Fire and the HRP Polymer pack for Duke3D...Duke3D runs fine with just EDuke32 and no mods, just Duke3D and EDuke32. But when I try the HRP Polymer pack, it says in Terminal "NVIDIA: Direct Rendering failed, attempting indirect rendering." This is fine...if I want the game to lag like hell, I'm sure my video card and the driver for it support DR, the video card is a NVIDIA Geforce FX 5200, the same message appears in terminal when I run Frets On Fire, I think it does with other games too, if someone could explain how to enable Direct Rendering.
for christmas my parents got both my younger sister and i acer mini computers, model d250-1958. my sister was trying to change her password that lets herself as a particular user log in. somehpw she messed up the password and its not what she thought it was and now she doesn't have any way of accessing anything. i thought that there might be an ovveride system or a reseting trick. i've looked in the manual but cant find anything of the sort for either of the two options.
yesterday i installed slim login manager on my computer (eee pc 1018p, ubuntu 11.04), and now it cannot get passed the ubuntu loading screen (with orange dots underneath) when booting. i tried booting into recovery mode and that didn't work either. i also left the computer trying to boot overnight and that didn't work. basically, during this loading screen that should eventually bring you to the login screen, i can alt+tab to see the progress of the load. the progress is stuck on
Is there anything I can do from grub to remove slim?or, is there any way I can access my ubuntu partition and save all my files?
My OpenSUSE 11.2 is working fine as samba server, no problems, but I have a problem with KDM.My default init runlevel is set to 5 and every time I try to login at KDM (KDE4), the monitor goes black and returns to the login screen.If I hit Ctrl+Alt+F1 to go to console and start /usr/sbin/console-kit-daemon manually, press Ctrl+Alt+F7 to return to KDM login, everything is fine.What do I have to do to fix this issue?
I successfully installed linux mint 9 and at the same time update the system. Now that everything is running, I returned the pc to the owner, but when I power it on, no display. You can see the post but no display after that. And 1 more, I press the shift while loading grub2, nope nothing happens. And also tried booting the CD installer, same results.
I installed the system using an old 15" CRT monitor and the owner had a AOC 1619sw LCD monitor. I found this thread from ubuntu which I think was the same problem as mine, [ubuntu] Help! No display/keyboard on boot with differnet monitor - Ubuntu Forums, but no solutions yet.
