Ubuntu :: NTB Freezes Display Turns Off After Starting XFCE?
Nov 10, 2010
I have fresh installation of Ubuntu server upgraded with apt-get dist-upgrade and with XFCE4 installed on my notebook. The problem is whenever I type startxfc, startx or X, the NTB freezes, CRT display connected to docking station/port replicator turns off, LCD in NTB gets black. The system does not respong to any signal, even the alt+sysrq ones. If I even install Xubuntu-desktop, as the X gets loaded every start, system everytime hangs after few seconds and I cannot do anything. Now I reinstalled and tried autoconfiguration with Xorg -configure. If I start the X with this configuration file, the result is still the same. Log at /var/log/X11/ seems to be blank.
Any ideas? Should i try to get drivers for my video card? I thought this is not necessary, the X server should start without anything, even only with basic resolution settings. As I looked, the video card chipset (Intel 82852/82855) is detected in my /root/xorg.conf.new file.
suspend has always worked fine with 11.04 and now it stopped working a few days ago. How can I figure out what is going on? The display turns off but the computer never turns off and the only way to bring it back is to hold the power button down and then start it back up.
the above event usually happens to me when im logged in to xfce my screen suddenly goes black for like 1 sec then my background becomes my background in gnome.. what does this mean? should i remove the gnome or there's some other options i can do to prevent this?
On a fresh install of Debian 8 with XFCE (with a NVIDIA GeForce 210 according to lspci, and a P7P55D Asus mainboard), I just added a second monitor. This second monitor does not switches off even though the first one does due to the Screensaver Preferences → Advanced → Off After 3 minutes.
The new screen is a HP Pavilion 25xw plugged in using a HDMI cord.
The old screen is a Philips 190S plugged in using a VGA cord.
The new screen (HP on HDMI) only goes blank when the old one (Philips VGA) turns off.
Two tests:
- on the same machine, I also have Windows XP: both screens turns off at the same time with the power management. - I tried on Debian: Code: Select allsleep 5 && xrandr --output HDMI-1 –off
It turns off the second monitor, so I know that it is possible to turn it off from my Debian.
How to set up the system so that both monitors power off when the machine is not used?
i run opensuse 11.2 with kdebase4-4.3.5-0.1.1.x86_64 on a hp elitebook 8530w. when i start opensuse and the sound is initially turned off, it will be turned on while starting. if i turn it of manually (by pushing the appropriate button) it will be turned on again. I assume that there is a script like .bashrc for bash scripts which tells the system to turn on the sound. Does anyone knows whether there is such a script and if yes, where can i find it and edit it?
The screen of my years-old HP laptop (running Natty) freezes and eventually turns black. Ctrl-Alt-F# works to switch to the terminals. My fan is even louder than usual. I spend some time fooling around with ps and kill and shut down some of the most resource-consuming processes, which quiets the fan a bit, but tty7 still shows a black screen except for my mouse pointer.
I finally decide to shut it down altogether, but then I think to myself, "Self, you've used the power switch to shut down before in this situation, but shouldn't there be a more proper way to do it in the terminal?" So I try shutdown, I have trouble with it, it proceeds to get hopelessly tangled up, and it looks like it's frozen up in mid-restart when I throw up my hands and decide to go for the old power-switch-for-five-seconds method after all. Now when I start the computer and select Ubuntu from GRUB, I get this:
I've recently installed ubuntu 10.10 alongside windows vista as a dual-boot on both of my computers. This question pertains to my asus eeePC 900HD. I'm quite new to ubuntu, so I'm sure I'll be needing a lot of .
I was having the problem of the computer freezing up when I unplugged it, I seem to have that fixed (gconf settings).One similar problem remains. After a minute or so of the computer being idle, the screen will fade to black, then, once the mouse is touched or a key pressed, the computer comes out of its idle state and prompts for a password. I've opened 'gconf-editor'/apps/gnome-power-manager/ and in the /actions directors set the values of 'sleep_type_ac' and 'sleep_type_battery' to 'nothing'. In /backlight I've switched the values of 'dpms_method_ac' and 'dpms_method_battery' to 'off'. Also in /backlight I've switched the values of 'idle_dim_battery' and 'idle_dim_ac' to 'false', and just to be sure, set the 'idle_brightness' to 100% and the 'idle_dim_time' to 999.
I have just upgraded from OpenSUSE 11.3 to 11.4, and now regularly about every 15 minutes my monitor display goes blank for a split second. My video chip is NVIDIA GeForce 6100.
I am using gnome-shell (3.14.4-1) desktop environment and i have a problem that i can not find any config to solve it, Lock screen turn off and on again display every 15 seconds with out any reasonable reason !!!!
I have a Dell box that got a fresh install of Fedora 13, along with XFCE during the initial installation, and it works just fine from a local monitor/keyboard/mouse setup.Now, in wanting to setup VNC to allow a remote XFCE desktop, it's not quite starting up properly:
The result is that I'm able to connect to the VNC session from another computer, but all I see is my XFCE desktop pattern image, and the XFCE mouse cursor (not in a spinning 'wait' state; I know it's the XFCE mouse, since my VNC client has a simple dot cursor that gets overlaid over the XFCE cursor, and I can move the mouse around the screen and the cursor follows); no menu bar, no tool bar, no desktop icons.I've tried changing the last line of my xstartup file to "startxfce4 &", and "startx &" with the same result.Is there a log file I can look at that would tell why XFCE is not fully starting up?
New build of Slackware 13.1 x86_64 in Dell E4310 laptop. The stock install works fine barring a few bits of hardware but after recompiling the kernel X loads and immediately freezes, whence I need to soft power down (I cannot switch back to a console). On capturing stderr from the command line, when executing startx I get various warnings including:(polkit-gnome-authentication-agent-1:2368): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failedCan't really tell if the above is relevant... Sorry I can't dump the lot because the machine isn't on the net yet.
There is nothing errorwise in the Xorg log after a reboot. The very last line relates to a video mode with modeline info etc. I have compiled either into the kernel, or as modules everything I think I need though unfortunately I seem to have to load them all manually, so I hav no idea of I've missed something important. This includes all the Intel drivers i915, drm, intel_agp etc.Googling suggests bugs with polkit and I don't know why gnome has anything to do with my system in any case.Other thing that I find annoying is that xorg.conf no longer exists and I am relying on the HAL daemon, about which I know nothing. It took me ages to find how to change the X keyboard map - very frustrating. How do I confirm which video driver etc.?
I've trouble with booting up xubuntu koala: When switching to the x11-login, the computer freezes during the change of the screen-resolution. Even switching to a console (ctrl+alt+F1/F2/F3...), ctrl+alt+del or pushing the power-button is not possible. After switching off the PC manually, it won't boot at all and freezes directly after switching on again (at bios-time).
Turning the PC off and on again helps - everything is okay afterwards. This doesn't happen always but it is annoying. Sometimes I have to try this procedure 5 o6 times until I can use the computer. Which of the thousand of log-files is the right one to look in? I am using Xubuntu and a Ati Radeon Xpress Graphics card, along with an AMD64 and the 64-Bit-Version of Xubuntu.
I thought I'd try XFCE having used fluxbox for a while now, always keen to try something different. I've installed everything XFCE related from the package manager and it is mostly working well. The problem that I am having though is that I cannot see the display settings. When I try to access them through the menus I am presented with the following:Unable to start the XFCE display settings - The video driver does not support video outputs.My graphics card is GEForce 7050/nForce 610i. nVidia drivers are all up to date. So far I've been unable to find an answer on XFCE forums.
I did a fresh install of F11 and everything seemed OK until I started OpenOffice, the OpenOffice loading box shows up then Fedora freezes and I am forced to do a hard restart. I repeated this and it seems to be happening at random with the same default settings of a fresh install.
I recently installed Debian 8.2.0 on an older machine (circa 2008, AMD Athlon Dual Core 5000B Processor, Nvidia nforce MCP61P Chipset, Nvidia Geforce 6150SE nForce 430 onboard video).
The install went smoothly, but occasionally the screen scrambles (see example below)
I have to force restart every time this occurs, and I'm not entirely sure what causes it. It used to only happen if I launched iceweasel too soon after login, but now it happens at any random time (in the middle of doing an image search, or right at the end of a 6 hour work session without any hiccups. I have only found topics on "screen blanking", and similar issues when using brightness controls on laptops, but nothing specifically like this.
I'm having trouble starting Fedora 14 on my computer. The startup procedure freezes while starting system logger. Before this started happening, I had formatted one of my logical disk partitions which is supposed to be mounted under the /var directory. I think may be the cause of this problem. However, I don't know how to fix it, as I can't get into the Linux command line to do a umount. I don't have a CD with which to repair the system, so is there any way to fix this problem without one?
I am running hummingbird exceed on Workstation with an ip address of a.b.c.d, and connecting to a sun machine with IP address x.y.z.w running Solaris with XDMCP. From the sun machine, we commonly telnet to other sun and linux machines and run X applications.
We have just installed ubuntu 10.04, and I can telnet into that machine no problem.
However, running xterm on the ubuntu machine fails:
How can I know the display resolution (e.g. 1280x1024 px) without starting X?I mean: let us suppose that /etc/X11 was renamed to /etc/x11. After reboot Debian starts in text mode only.
I'm hoping someone can point me in the right direction. I've tried Google searching and searching this forum, but haven't found something similar to my issue. Yesterday, I installed 10.04 off of the live CD onto my Toshiba Satellite A45-S250 laptop (P4 2.8, 1GB RAM).
The main problem is: -if the computer sits idle for more than about 5 minutes, the display will freeze. Image stays on screen, but the computer appears to be non responsive to all input.
-I thought it was a screen saver at first, but it happens even with the screen saver disabled. -I can still SSH into the machine from my desktop computer. I get a normal prompt, and it seems to be working fine from the shell. This is how I have been restarting or shutting down the machine after a freeze.
Secondary issues (that may help diagnose the problem):Even when this laptop appears to be functioning normally (pre-freeze), I cannot switch to any virtual terminals. Well, I can, but when I get there, something is not right. The text does not display properly. It sort of strobes on and off near the top right hand of the screen. -On shutdown, I get a weird colorful displays of what I can best describe as "static". The closing splash screen may just blink on for a second. Other than that the screen stays black until the machine shuts down.
-I've run versions of Ubuntu going back to Breezy on this machine, mostly without issue, and it has been a full time Ubuntu machine since the release of 8.04. These symptoms all appear to be related to video / display.
java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02, mixed mode)
And when i am trying to run my gameserver scripts i get this error.

This is not my desktop computer but my remote server.
I had a computer running a NVIDA Quadro NVS 450 with 4 screens on Fedora 14 and it worked fine. I make a new install with Fedora 15 and I am now not able any more running more as one screen with Fedora 15. I am running now on run level 3 and when I configure the file /etc/X11/xorg.conf for one screen, Gnome starts correctly. When I change to two screens, and runs "startx", Gnome 3 starts and displays only the background picture without any manager. The file /var/log/Xorg.0.log shows no errors.
I am having a problem with Installing Ubuntu 9.10 on My desktop. I have burnt the disc at the slowest speeds possible, and tested it on my alternate PC's, and it works. Not only, I have extensively tested the disc to verify it's integrity. So it ISNT the disc. It is a component of my Main Desktop that is causing the issue, I am of the thought it is my IDE hard drive.
Firstly, My Specs; CPU: Intel Q9550 Quad Core (Running at an Overclocked 3.4ghz) Motherboard: ASUS P5QL PRO P45 Chipset , 1600 FSB , etc RAM: 3gb of DDR2 Team Elite RAM (running at 667 in Win 7) Hard Drives: 500gb Western Digital ECO Sata Drive (Win 7 System Drive) and an IDE 250gb Western Digital drive reserved for Linux (I have coded a boot manager to switch between the two)a DVD-ROM drive is on the other channel of the Single IDE port on the Board Video Card: ASUS/Nvidia GTS250 1GB
I think that covers all the vital hardware.
My problem is that when i boot into the live CD, and attempt an install, the installer freezes at the point of setting up the partitioner/scanning drives, at 47%. SO, the partitioner does not get a chance to start.
I have a gaming system, and it has all the latest gear, i7, 16gb ram, etc and it installs on that (i plugged in a resh drive to test)
This system I am trying to use ubuntu on is my MAIN system, I use it for study (PhD Science...science geeks rule!) and I am attracted by ubuntu's features, especially for scientists.
So I take a glance at the time, and realize the clock has been showing the same hour for ages.Basically, if I use the gnome-panel menu for launching empathy the panel freezes. The workaround that I use is switching off showing seconds and switching it on again on the date format menu of the panel. (I never used seconds on the date format, but that way you realize the panel is frozen)I've seen this behaviour in two diferent computers I use, any hint on what may cause this? Every applet keeps working as usual, but the menu display is frozen.I'm on 10.04, using version 2.30.2 of gnome. Steps to reproduce: click on the envelope icon of the menu and launch xat. It only happens the first time (when empathy is loaded) and it gets solved if you start empathy through sessions or whatever (The problem with the sessions workaround is that I can't manage to make it started without focus).
Like for instance, if I have Ubuntu Lucid Lynx installed with XFCE, and it has an applications made for XFCE. will the applications also work on say some other distro like, Wolvix, that is an XFCE-based distro~????
What I am trying to say is: Do applications that are made for XFCE, work on ANY distro that has XFCE installed?
my computer this morning, then it suddenly turns off. I press the power button and nothing happens. After a minute I press it again and it turns on, but it quickly shuts down when it hit the boot screen. After I tried turning it on again, but it turns on for about 2 seconds and quickly dies. Some times it turns on itself and then turns back off. This happened when I had WIN XP installed too (which was about 2 years ago). I run full Ubuntu 9.1, no double boot. Is this hardware problem or a virus that affects both Windows and Linux? :O
I've read many posts about other people having this issue and I can't seem to find one that is the same problem I am having. I'm totally new to ubuntu and linux as well for that matter, Basically I wanted to give linux a try and started doing some research and liked everything I read about ubuntu. I went to the website and used the wubi (I think that was what it was called) to install ubuntu. Now when I boot my computer it asks me which operating system I would like to use. I navigate to ubuntu and press enter and it starts up with no problems what so ever.
At first I was really surprised with how easy the installation was and how great everything was going, however. After looking around for about 10 minutes, the screen abruptly went black and then my monitor had a small blue box on it with "No input" on it before the light went from blue to orange. I tried hitting every combination of keys I could think of and in the end had to do a hard restart.
Long story short. every time I use ubuntu my monitor shuts off after about 10-20 minutes, regardless of what activity I am doing. I've tried going to /apps/gnome-power-manager/timeout/ to make sure that sleep_display_ac was set to 0 (it was), I've turned off power management using the power manger under preferences. No matter what I have tried, it continues to be a problem.
