General :: Ubuntu 10.04 Freezing And Ctrl + Alt + Backspace Does Nothing But Music Keeps Playing
May 26, 2010
I'm having intermittent problems where the screen will freeze in Ubuntu. I've tried using Ctrl + Alt + Backspace to restart the X-server, though this does nothing. When the freeze occurs, there's a small square of black dashes around the mouse pointer - maybe 1 inch in size. These dashes look a lot like a 2d barcode. The rest of the screen looks normal, but I can't move the mouse and none of the keyboard shortcuts work to do anything. However, music that I begin playing before the freeze continues to play, which seems to indicate it hasn't stalled up completely.
I've noticed a similar freezing problem when I'm using Windows 7. That is, I see the same barcode like dashes around the mouse pointer when it freezes up. So I'm guessing it's either a driver or hardware problem. I thought if it was a hardware problem though, the whole computer might stop working (i.e. music would stop playing)? The video card I am using is an Nvidia, and I believe it's in the 7600 range. In Ubuntu I have the drivers for the card set to the latest available (proprietary). Ideally I'd like to be able to continue using the proprietary drivers. Is there any known issues with the drivers for this model graphics card
I recently switched from Windows XP to stable Debian w/KDE on my work dell B120 laptop. I have been trying to diagnose freezes. In the evenings I have been leaving an SSH connection to my home computer. I leave a command running that writes the current time to a file every ten minutes. The past two nights it has stopped writing the time after a couple hours (not at the exact same time), and I am no longer able to ssh from my home computer to my work computer.
When I get back to work, the work laptop is frozen. CTRL+Alt+Backspace does not help, neither does CTRL+ALT+F1. Ctrl+Alt+SysRq works sometimes. It has not yet frozen while I have been present.
I tried disabling the screen saver and monitor power controls in KDE, thinking that those only come on when I am away, so they might be the cause. But it did not help.
I took the last time recorded by my ssh connection and looked through the logs trying to find something that happened at that time, but the only event occuring around the time the SSH connection dropped was a chron job that runs every hour. As far as I can tell, the chron job does not actually do anything but write to the log each hour.
So obviously I need to post more information. What would be helpful? Which log or configuration files might contain clues?
I see these lines in my logs: kernel: Kernel logging (proc) stopped. imklog 3.18.6, log source = /proc/kmsg started.
It appears at 6:25 AM each day between when the SSH connection drops and when I arrive in the morning. Do I need to restart logging?
I am an Ubuntu/Linux noob, I installed Ubuntu a few weeks ago, and it sometimes gets extremely slow and crashes. I can't get out of the crash with ctrl-alt-backspace and I have even tried the key combinations suggested here to no avail.
Ubuntu 9.10 Computer: IBM T42 mem 500 MiB Intel Pentium 1.70GHz
The crashes usually involve Firefox being open + another program ( could be pdf reader, calibre, or something similar). I try to keep the amount of open Firefox tabs below 5 as it gets very, very slow (that was one of the reasons why I decided to install Ubuntu, in the old windows XP installation Firefox was also excruciatingly slow).
On fedora 10 and backwards you could use Ctrl+ALT+Backspace to restart X, this was massively useful in resolving any issues with hanging x processes and so forth... without losing session data.... it seems to not work in fedora 11...
Since I wasn't able to figure out how to enable ctrl alt backspace in kde I thought I would explain how to do it from the command line. Open /etc/X11/xorg.conf as root. Then add this to the file.
I can make it work if I change it to some other sequence (Control-j: unix-word-rubout makes ^j erase the word), but I can't make it work with backspace.
I have problem with some applications in X. When I want to unlock Xscreensaver it just meses my X and I must Ctrl+Alt+Backspace. I installed slock and thought I solved the problem that way, but same happened with Xpdf.
After loading all the apps I use last night with a working FC14 x86_64, I powered up this morning and nothing happened after starting atd.1 try an alternat kernel same effectstart in init 1, OK go to init 3 OKran startx .. failedlook for xorg.conf.. no fileNow if Iwas still running mandriva , I would have typed mcc and bought up the control panel so I could have sorted out the Xorg problem, or tried. There really needs to be something like this.I found that gdm was not installed so installed it.It will now boot up to the login screnn, but wont accept my passwd.restart in init 3, login as root and add another user and set the password for that user.I also rest my passwd as welll.boot up again and get authentication failure on both users, and I cant login as root as someone removed that feature.
Also I can't use Ctrl-Alt -backspace to killl X so I have access to CLI so I can login there and run startx.I suspect several gnome packages have been removed/lost as I use lefthand mouse settings and the mostsetting are back to default.All I have is a live CD to gain access to the forum, and I only have one computer.There really needs to be a fallback to one of the smalll DMs on fedora so in situations like this you are nt forced to use CLI, thats if a new user would know how to access it. As there is no bootsplash, you have to already know to hit return and wait for the bootsplash.
IMO this a is a seriouss flaw, in what otherwise is a good OS.In the meantime I'll try and install XFCE to get X running, but I will need some help getting gnome back.I'll load gnome-panel and see if yum will pick up the rest as depemdencies.I hope this isn't a bug, as to lost the DM after the first machine power cycle is fairly drastic---------- Post added at 08:52 AM GMT ---------- Previous post was at 08:18 AM GMT ----------I resorted to yum install gnome-*which loaded 255 packages, including gnome-desktop, gnome-common, all the gnome applettsThis wasn't just one or two packages corupted, it was removal of the DM altogetherSimilar effect to running "rm -rf gnome-* "
I recently purchased a linux VPS from [URL] just to learn and play around with. I currently ssh into the machine via Putty from various Windows boxes. Is there anyway to throw some mp3s on the remote server and then have them play locally? Server is currently running Ubuntu Server 10.04.1.
I am doing a project on rdesktop. My aim is to setup a write/copy protected session. I have made rdesktop connection between two Linux machines using Xrdp.Next I want to disable the ctrl+x,ctrl+v keys and the cut and copy option in mouse right click at client side
I'm having a weird problem just when I try to play music/videos. The song/video stops playing after a couple minutes, but everything works fine on my computer. This happens with videos on websites and files being playing in media programs(which I've tried several different ones now). My speakers are pretty old and need to be replaced soon, but I didn't think that would really cause this sort of issue. I've tried various suggestions for other sound issues, but haven't really seen anyone with this exact problem
i'm using debian wheezy and whenever i'm playing a webm video, typically on videos, totem and mplayer can't play video. the video just freezes. (i assume because they both use gstreamer.) when i try to use vlc when those 2 aren't working, the video does play but there is no sound.
i installed xmms whit this command "yum install xmms"but i receiving an alert "MPEG Layer 1/2/3 not supported". How can I play my musics.I updated fedora 10 to 11.but it does not work
I am using C++ and Gtk to make a music player. I was looking for some library that will allow me to play a music file, preferably mp3, wav, aac, and more if possible. Also, how can I get info on the file like the artist, album, genre, etc. Hopefully the library will do that also.
I'm currently running ubuntu 9.04. I'm able to mount data and MP3 audio CDs but I'm unable to mount and play regular audio CDs. When I try to mount it I get the following message:
Unable to mount Audio Disc Drive /dev/sr0 does not contain audio files.
Windows does not have any problems playing either the regular audio CDs or audio MP3 CDs.
My PPC iMac G3, 600 MHz, 768 MB ram machine (blue box) machine has 16 MB video ram and 256 MB backside L2 cache. When I insert a music CD, it doesn't seem to recognize it. Nor does an icon appear on the screen indicating that I loaded a disk. When I insert a movie, Lucid waits a moment, spins the disk, then ejects it after about 60 sec. Data disks act similarly, but no ejection. Disk spins momentarily, no icon appears on desktop, disk does not eject, No further action.
I really like gnome-do..i installed the rhythembox plugin and Super + Space and typed some songs titles...and pressed enter, i suppose at this point rhythembox (which is already in system tray ) should play the song....but what actually happen...is nothing..literally. so what ? or how should i play a song from gnome-do !!
I have an Ubuntu 10.04 desktop PC (desktop) that I access remotely, i.e. with no monitor and keyboard attached. I do this by making an ssh connection to "desktop" from my laptop (also running Ubuntu 10.04).
I have all my music stored on "desktop" and I want to play this remotely through the soundcard on "desktop" which is attached to a hi-fi amplifier, from my laptop.
I tried running, say, rhythmbox, on "desktop" through ssh X11 forwarding to my laptop but cannot play music - it says that the right codes are not installed although they are because I can use rhythmbox on "desktop" directly (attaching a monitor and keyboard to it).
I have windows and ubuntu on same pc. I recently installed ubuntu on a partition other than windows.When I tried to play an mp3 file in ubuntu, it started downloading file and plugins. After the download, the program started playing the music but I could not hear any sound. I have no problem in playing music in windows and the speakers are working fine. Do I need to download some plugins or any software for ubuntu linux? If yes, how and from where? And how to install that? Or is there any other problem?
" Mark the start of the text with "v", "V" or CTRL-V. The character under the cursor will be used as the start.""With CTRL-V (blockwise Visual mode) the highlighted text will be a rectanglebetween start position and the cursor."I can mark the start with "v" or "V".But it doesn't work when I push ctrl+V.
I've been having problems with it for months, assuming some bug fix would just happen, but it hasn't, so here I am.The general symptom is that I can sit listening to music for around 20-60 minutes, using audacious/banshee/whatever, and the music will make a crackling noise and suddenly stop. Killing pulseaudio and the application remedies the problem, but obviously that's not a solution.I have a ca0106 sound card. [edit: originally had emu10k1 here -- that's a sound card I have that's unused in the same system.]
/var/log/messages usually indicates a message like this, or something similar: Mar 6 00:22:29 localhost pulseaudio[4872]: alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 18446744073709542688 bytes (384307168155 ms).
I have compiled Bluez 4.50 for arm and have installed it. The bluetoothd daemon is running fine. But when I enabled the blueoothd -nd & i get an error saying, Failed to access HAL. After a bit of digging, i tried installing hal on the board in vain. The hcitool scan runs fine and shows all the devices in the vicinity. I compiled agent.c from the test folder and am using it to pair in command line because i donot have python on the board. I see the packets getting txd and rxd in the hcidump when i try to pair with the headset. even the light in the headset changes after pairing. but i donot hear any sound when i play a *.wav file.
There is a piece of streaming music I want, when I open it, the song plays using totem browser plug in. Is there a way I can capture the song and keep it as a file (or put it on my mp3 player), preferably without downloading anything.
I recently bought a new laptop. compaq presario CQ41 109AU. It does not come with a pre-installed OS so i've decided to put an Ubuntu on it[karmic koala 9.10]. I successfully completed the installation procedures. however, it does not produce sound when loggin in and playing music files. I gone to look if the settings where put to mute, but they were not. I tried installing a MS Vista in the other partition and the sound worked.
I recently found that I can sync my music to my iPod without iTunes/Windows. I tried using Rhythmbox and it seemed to work. That was, until I tried playing the album I added. It just skips through the album.
When attempting to play an MP3 which is stored on my computers hard drive the song just stops playing part the way thru the song.I have had this happen on multiple computers that have Ubuntu/Lucid installed.Sometimes I get the error message that is attached,ut sometime I do not get this error message, the music just stops playing.What is causing this. I have another computer that also has Lucid installed and this does NOT happen
