Ubuntu :: Can't Get Out Of The Crash With Ctrl-alt-backspace?
Feb 8, 2010
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...
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
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.
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?
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 have 3 layouts: USA, Russian and Hebrew. In Hebrew the W key is mapped to apostrophe, so Ctrl+W in Hebrew layout doesn't close tabs in Firefox. There is no workaround for it as I see by now, so I am trying to get it work this way:I want to map Ctrl+W in Hebrew layout(which is actually a Ctrl+') to be a Ctrl+w. Here is what I got from xmodmap:Code:$ xmodmap -pke | grep 25keycode 25 = w W Cyrillic_tse Cyrillic_TSE apostrophe WAs you can see, there are pairs for each layout, each pair tells what happens without and with the Shift key pressed.
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 just installed Ubuntu 10.10 x64 and already am really annoyed by Firefox, which freezes my mouse after changing a tab (with ctrl+tab, alt+#) or closing it (ctrl+w). After about one second, i can continue working as usual. Changing Tabs by just clicking on one does not freeze anything...Maybe some of you would think now if I am crazy because of complaining about such a little thing, but it is really annoying if you are used to work fluently with ff.Edit:I today noticed, that not only shortcuts in firefox, but all Hotkeys freeze my mouse for a second. For examle ctrl+c, ctrl+v, super+e or anything else.Do you have any Idea what causes this behaviour? Reinstalling ubuntu didn't change anything
" 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.
anyone has a clue why 'ctrl+a, k' nor 'ctrl+a, :kill' doesn't work for killing one of screen windows? Other screen's commands invoked with 'ctrl+a'seem to work.
I just spent a few days ripping out all the broken/buggy apps that are in the opensuse 11.2 official repos so I can finally get working software(openoffice, thunderbird, wine, eclipse, rubygems, rails, and a few others required getting the "official" versions from their respective websites to avoid strange behavior and outright broken functionality).
All of which makes updating more annoying and time-consuming. Why are opensuse packages so different anyway? Anyway, the last thing that I have noticed to fix is Konsole. For some really bizarre reason ctrl+z and ctrl+c do not work without a third keystroke: enter.Maybe this is something new with the KDE team, since they seem bent on making simple things that already work more complex, but given my experience with crappy packages in the suse repos, I am thinking this is the problem. I have looked over all the config settings that I can find and nothing fixes this affront to productivity.
I've been using Kaggregator in KDE-PIM, which uses Konqueror as the browserto go to links from Kaggregator.Unfortunately, Konqueror no longer seems tobe able to Copy highlighted material with Ctrl C, the way we've done it forever.Is this a setting I've missed? Or is this a new "feature" in Konqueror?
I'm trying to write a init.d script to daemonise a sagemath notebook server. Here's what I've done so far, I've copied /etc/init.d/single for the structure, and tried to use dtach to provide a handle to access the process. However, my main problem is issuing the signals to kill the process (Ctrl-C) from a bash script and exit dtach (Ctrl-`)
I use Ubuntu terminal/putty to 'ssh 1' my routers, but backspace does not work like normal. with telnet and ssh 2 its perfect. Can any one help me how to fix this issue?
the " backspace " button on my toshiba A 200 laptop works when i use it to navigate the ubuntu system folders such as documents, movies, music, computer etc ..however, it doesn't work at all within firefox !is this normal ? how can i get it to work within firefox so as to be able to make liberal use of the keyboard ?
I installed Debian Squeeze yesterday and I got almost everything working except for the backspace key in any browser I've tried..I'm running it on HP Mini 210 if that can help w/ something and one more i tried upgrading it to testing but a verry long and boring text file appears and to close it and continue, i have to press the end button the problem is that i do not have one .. i've tried every single other key on the keyboard - still nothing.
One of the very few things I miss from Windows is that when you press LeftShift+Del the delete key acts like the backspace key, in other words you can use Del to delete forwards and LeftShift+Del to delete backwards.
I've been reading man pages such as xmodmap and used xev to get keycodes but I can't work out how to map LeftShift+Del to Backspace.
I have an old computer on which the backspace key is broken (i.e. it makes no physical connection) and I would like to reassign it to another key. How would I do that?
I am using vi(m) on a remote computer and the backspace key is not working as it should be (or as it does work on other machines). The desired behaviour is: delete the character left from the cursor.But when hitting the key always the right character is being deleted.how to set this up in the vimrc? I tried the following settings without success:
fixdel set backspace=indent,eol,start set nocompatible set smartindent
[code]...
I even tried different combinations with h/H. And also a google search did not give a solution.
I use screen to manage multiple ssh session and it is quite neat. But the problem is that if I type something wrong and want to use backspace to delete it, it just stays there and does nothing. I don't have that in another computer but it just happens in my current box.
