General :: Re-enter Interactive Mode After Ctrl-z?

Jun 14, 2011

In interactive mode (in Octave, gnuplot, R, etc.) I occasionally press Control + z by mistake. This pauses the program and kicks me back to the terminal.Is it possible to re-enter the original interactive mode (with all the stored variables)?

To reproduce:

~> octave
octave:1> a = [1:10];
octave:2> ^Z


How can I recover my session with the variable a defined?

Fedora :: Boot Sequence Of 11 Using Lvm - Message - Press '1' To Enter Interactive Startup ?

Jun 15, 2010

I've been fiddling about with vortexbox (the one before 1.4 I think), for a while. This is a music ripping and server rpm setup using Fedora 11 as the base.

As it was on a test machine, decided to try changing the logical volume sizes of LogVol00 and LogVol02 to fit a few more cd's on 02 before getting a new pc (just to see how it works).

Logged on and opened up the graphic version of lvm (using gnome). Then selected the LogVol02 logical volume, select edit, changed name to LogVol02-Storage, saved and logged out. Rebooted vortexbox since then its been unable to start properly (is this a kernel panic?).

Read up a lot on lvm on the net, have access to Fedora 11 disk 1, so logged on. Eventually managed (I thought to) to change LogVol02-Storage to LogVol02 using lvrename.

However, still refuses to boot completely.

The message it gives is as follows (sort of): Welcome to Fedora Press '1' to enter interactive startup

Setting up Logical Volume Management: 3 logical volume(s) in volume group 'VolGroup00' now active

*** An error occurred during file system check.
*** Droping you to a shell; the system will reboot when you leave the shell.

Give root password for maintenance (or type Control-D to continue):

Loving vortexbox appart from this. Will it be easier just to reinstall everything? If so, is there a way of listing all the changes I've done so I can reproduce (I'm thinking of just looking at all the commands I ran on the CLI).

Otherwise, is there a way of listing all of the commands I ran in terminal and piping them into a file so I can see what I need to do to rebuild after reinstalling?

General :: Sudo Broken. Unable To Enter Recovery Mode To Fix It?

May 5, 2011

I broke sudo when I wrongly edited a file in /etc/sudoers.d in vi(did not use visudo :-().I read that I could fix the same by rebooting into the 'Recovery Mode' by selecting the same from the grub menu.

However I'd earlier disabled the showing of the grub menu by editing /etc/default/grub. As a result I can't seem to go into recovery mode to fix my broken sudo.

General :: No Prompt For Root Password After Attempting To Enter Single User Mode?

Jul 13, 2011

I followed instructions to enter single user mode by adding single at the end of kernel line but after that it doesn't ask for root password but brings up the sh# prompt. Isn't that supposed to be insecure? I understand for this the grub password can be applied but even after adding "single" it should ask for root password..or it should not..??

OpenSUSE :: Using Ctrl + Alt + Fx (switching To Text Mode)?

Aug 7, 2010

I have been using SuSE Linux in text mode for the longest time (since 8.0) and I'm often more comfortable working in that mode. I have just installed 11.3 with GNOME as a fresh install on my dual-boot laptop and I am pretty happy with the way things work. But I still languish for my text mode from time to time.

So: I know about right clicking on the desktop and selecting "Open in Terminal" and that should really solve my needs, but I read here in an older thread about using Ctrl + Alt + F2 (as it happens, it can be F1, F2, F3, etc.) so I decided to try it out. Well, when I do that, I get exactly what I expected --- a black text screen with a login: prompt and I can do all my little texty things just as sweet as can be. Except for one thing: I can't get back! The only way I've been able to get back to a GUI is to use "shutdown -r now" as user: root. Also, Ctrl + Alt + F1 removes the GUI completely for all four terminals. Can someone tell me more about this function where I might read an "info" or "man" about it? I don't even know what it is called, so it is hard to know how to search. (Admittedly, I haven't tried Google yet.) uname -a ==> Linux 2.6.34-12-default #1 SMP 2010-06-29 02:39:08 +0200 i686 i686 i386 GNU/Linux

Ubuntu :: Cannot Enter Recovery Mode

Mar 31, 2011

I messed up my video drivers and now can't get into recovery mode. Pressing the shift key isn't working. All that happens is the splash screen appears in faded looking colors and then fades to white.

I've got an ASUS N61 laptop with an ATI Radeon 5730 graphics card. I just upgraded to 10.10 from 10.4 and was trying to install the open source video drivers. I must have messed something up and can't get to the terminal now.

Ubuntu :: Login Authentication Failed And Cannot Enter Recovery Mode?

Aug 31, 2010

Earlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.

I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD?

Ubuntu :: Map Ctrl+W In Hebrew Layout(which Is Actually A Ctrl+') To Be A Ctrl+w?

Jan 5, 2010

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.

Fedora :: No Monitor Input During Boot, Unable To Enter Text Mode From X Window

Nov 24, 2009

I installed Fedora 11 on my system (see below) using the i686 DVD. The graphical install worked just fine, and after the system booted back up, the X server was working very well.

There is no boot text. On the other system with Fedora 11, I can see the boot text scroll by in the window and/or a progress bar at the bottom of the monitor during the boot sequence. On this system, the monitor says "No Input", and nothing appears until the login prompt for the X window. I am able to enter the BIOS configuration page and navigate through it without any issues. I can also edit the grub commands before Fedora loads without a problem.

If I boot in text mode, no login prompt appears. If I wait long enough, the monitor enters the power save mode since it is not receiving a signal. I am able to log in to the system with my user name and password, and then start the X server. Once the server starts, the monitor turns back ON and all is well.

From the X window, I use the CTL+ALT+F2 key to enter text mode. The monitor stops responding. If I press the ENTER key a couple of times, then press ALT+F7, I can briefly see the text window with a couple of login prompts before the X window starts responding again.

How can I get the text mode to work? Why is there no input to the monitor when booting?
