View 5 RepliesI am trying to install ubuntu 10.04 on notebook, after choosing install, ubuntu starts after about 10 minutes with log screen, but I don't know logging parameters. Also the same with ubuntu 9.10. Hardware problem?
View 3 Replies View RelatedI recently installed Ubuntu on my Powerbook G4 1.6ghz 13". The install went fine along with the first boot off the harddrive. The problem came when I started the computer for the second time. X starts but the display comes up blank. To be sure I didn't mess up the install I reinstalled Ubuntu and installed all the updates and proprietary drivers as well as setup remote desktop options. I can now start the computer and get a remote desktop but nothing on the computer's display. I've tried to edit the xorg.conf but X has not created one. I'm at a loss of what to try next.
View 9 Replies View RelatedI'm running a Latitude E4300 with the Intel 4500HD integrated graphics. Lately, the display has started to flash on and off several times an hour. Usually all I have to do is move the mouse or hit a key, and the display comes back (the back light is on when this happens).
Once and awhile, my monitor goes into standby when this happens, but if I turn the LCD (a Dell 2007FP) off and back on, the display is back. This happens when using the internal LCD at 1280x800 or my external monitor hooked up via E-Dock.
I've tried a couple different monitors, and they all work fine. I have another hard drive for this machine that I have Windows 7 loaded on, and it works for hours and hours without exhibiting any video related errors.
I'm having an issue with my display. Every few minutes or so it dims and a 4 note chord is played.
I have isolated it to: "new-host-5org.kde.powerdevil.backlighthelperQDBusConnection: system D-Bus connection created before QCoreApplication. Application may misbehave".
And it most certainly is misbehaving. I'm running Jessie 8.2 with the KDE desktop on a HP Elitebook 8730w with NVIDIA Quadro G94GLM graphics.
I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.
Here's the sequence of events in how it's loaded:
1) The computer is turned on, and boots into F11 (x86_64)
2) A non-privileged user is automatically logged on
3) The gnome startup applications list contains an entry for a loading script
4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program
This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.
I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.
I'm running Ubuntu 11.04, using an nVidia graphics card. I have my TV hooked up to my computer and acting as a second monitor, using the Twinview option with the gpu. My monitor is set as the primary display, with the TV as secondary.
The problem I'm having is that when I turn my computer on, the main display is black, and all the load up information is output to the second display. Then, when I get to the log in screen, it is also on the second display.
I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?
Sometime after I upgraded to ubuntu 9.10 I've been having trouble with my wireless network connection.It will usually log on to the network, then disconnect a shortly after. Then try to connect again, usually successfully, then it cuts off again. Then connects again, then disconnects. FWIW, ubuntu 9.10 works on a different machine pretty consistently, so I don't think its a problem with the router.
View 2 Replies View RelatedHi I am new to ubuntu and am having major problems setting my displays up. my setup is a hd TV to the Left of my pc monitor, i have managed to configure catalyst to let me have a main display with the second display being an extension of the first, the problem is i cannot seem to swap my primary display, at the minute my HDTV has all the taskbars and everything on it while my pc monitor is just a blank background, i would like it so i could start a film playing for my children, then drag it across to the HDTV while i can still use my pc in the background.

View 3 Replies View RelatedI have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.
When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock
[code]....
I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?
View 14 Replies View RelatedI have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.
I have installed Fedora 14 Security Spin, and want to display all disks & partitions available in a GUI display. How can I achieve that?
View 1 Replies View RelatedI have just installed ubuntu on my second laptop. However, this one is giving me some grief. After several minutes, it completely locks up. No mouse, keyboard, anything. Just frozen solid. I had some issues installing it, and got around them by checking something like "nolacpi" and "noacpi" with the live cd, but now I don't know how to re enable those options. I'm quite computer savvy, but am still learning how linux works. For refrence, this is the system specs:
HP Pavilion Zx5000
Pentium 4 3.06GHz
ATI Mobility Radeon 9200 GPU
1GB RAM
60GB IDE Hard drive
I have to type this quick because Ubuntu will lock up on me.The screen goes black, the cursor does NOT move, and the only way to recover is to do a hard reboot. This happened when I had windows XP installed as well, only it would reboot the machine after 5 minutes.I barely have time to open one program and it locks up.Could this be a hardware issue?I tried taking out the video card I had bought, thinking it would solve the problem, but it does not.
View 6 Replies View RelatedI feel sure there must be an easy solution, but Im damned if I can find it. Im sure I've looked everywhere. Even when Im watching ....., the screen goes dark and when I touch the mouse, Im asked for my password again. It really is very very annoying. I go and make a drink, come back, and there it is again - I have to type my password again.
View 5 Replies View RelatedI have this problem since upgrade to lucid.
Every time I start my computer, from the power button, it crash after 6 minutes. It only could be recovered from the reset button, not CTRL + ALT + DEL nor REISUB.
I think it only happens if I don't touch anything in that 6 minutes.
syslog show this during crash:
Code:
Jun 10 07:46:21 antonio-desktop kernel: imklog 4.2.0, log source = /proc/kmsg started.
Jun 10 07:46:21 antonio-desktop rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="725" x-info="http://www.rsyslog.com"] (re)start

why it's hanging up.It hangs up 5 mins after startup whether or not any application is running.

My problem is, on Ubuntu, the laptop overheats and crshes very fast, 5-15 minutes. I have the AMD GPU driver activated, and it is all normal, I havent done any tweaks apart from a GRUB tweak, that only lists 1 Linux Kernal at a time.
View 9 Replies View RelatedI'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.
I am using ubuntu 10.4 on a Sony vaio and I never had troubles with the previous versions.just in those days something strange is happening. With no apparent reason, few applications running, the system will just freeze...sometimes I would be able to open a further application, some other things not. I have tried everything (in my knowledge)after which I simply use Alt F2, call the terminal and reboot (the only operation that the system will allow me to do.I have found no pattern of behaviour but his has happened with the following application running
Firefox, Openoffice and Rhythmbox
Firefox and Torrent
now Firefox alone (yes it might be firefox...but still, if I am not wrong it happened also when firefox was shut and I was working on openoffice)now I have logged on into xfce environment to write this message (and I am using Midori as browser)..
For some reason my computer screen keeps getting completely dim after around 10 minutes of inactivity. It's been happening when I use Oracle VM Virtualbox to watch movies on Netflix.I have all the setting on my computer so it doesn't dim the screen at all, so I don't know what to do now. You can see my settings on the attached images.

The screensaver is set to 1 hour and the power management settings are set to 'never'. I never had this problem with the previous Ubuntu version. I'm on a desktop rather than a laptop.
My bluetooth manager is dying every few minutes or even every few couple of seconds. This happens when i'm using bluetooth mouse. Mouse works correctly cause i've tested it in windows. In the attachment there is dmesg output. In dmesg i keep geting lines like:

followed by reconnecting both, USB dongle and mouse. Then it works for a while and dies again, over and over. It also happens when mouse it idle (no matter if 5 seconds or 5 minutes).[URL]..

The second i need (the same problem) to run program little more than every 12 hours, it might be in steps of 12 hours and 4 minutes (but 13 hours is much too much).
