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.
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.

How to enter into recovery mode in the latest version of Ubuntu?
I used to have a grub menu with options of
*Ubuntu
*Ubuntu Recovery Mode
*Memtest
and
*Windows
but later I installed Ubuntu alone on a machine , and i do not have GRUB menu. and i want to enter the Recovery mode.
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?
I have added to Debian Wheezy testing repositories. After a restart there is no desktop anymore just the wallpaper picture is visible but no desktop pop-ups.
When I want to install the desktop through recovery mode, I get an error message that it "can't fetch...repos". How I can repair /etc/apt/sources.list through recovery mode?
I am pasting sudo commands without problems as a user (ales in my case) and then immediately the ask the user password.
The keyboard seems to be dead, no keys work, not allowing me to enter the password.
I installed lucid last week, and this morning installed some updates that appeared in update manager and then started having issues with permissions so I rebooted. Now when I try and log in I get the message Authentication Error Normally this wouldn't be a problem I would reboot again hit ESC just before loading Grub appeared and go into recovery mode and change the password for my master user. But I never get the chance to press ESC, and even I hold the key down from the time my BIOS flash screen is up, I never get the GRUB menu.

I tried 'sudo wvdial' command. Then I am asked for my password. But I cannot type my password there. When I type, nothing appears on the terminal window. Ofcourse there's no problem with my keyboard.
View 5 Replies View RelatedI 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?

I installed ubuntu 10.04 by wubi. It works perfect until I installed and ran "startupmanager". I find that I can't enter ubuntu, even in recovery mode. The screen keeps showing "rstslog main process ended, respawning [fail]" and other text
View 4 Replies View RelatedI've got a, as it seems to me, strange problem.I've inadvertently deleted my user from the group admin so I'm in the same situation of a lot of other users (read a lot of messages about it).My problem is that when restarted in recovery mode there is no way I can choose the 'drop to the root shell' or similar in the menu.The menu appears for a second and then I've got an empty screen. If I press a key I've been requested for a username and password that of course is not what I need.

View 1 Replies View RelatedI logged in recovery mode via grub, it shows several options: like, resume normal boot
When I enter the resume normal boot it shows something like this:
xxx login:

And I entered my root password which I need for the command "sudo -i". But it shows incorrect password, why is it so?
Same thing happens with dpkg option also? Why is it so, I dont have any other passwords for my machine?
I am trying to run boot up in recovery mode in Lucid Lynx 10.04 on a Dell XPS M170. When it gets to [1107.134155][drm] nouveau 0000:01:00.0: GPU lockup-switching to software fbcom, it stops and freezes up and will go no further.
What does this mean and is there a fix?
I attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?

View 9 Replies View RelatedI 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..??

I wonder how to make su and sudo say what user's password to enter?
It's not a big problem for me because I have the same password for both my normal account and the root account, but still it would be nice.
I am a Mac/ Windows user, forced to use Linux for my college work. I do not know where to enter commands like $ sudo /usr/etc/eth0 mvntz -do4i or how to make them work
I had a problem - the Wi-fi card in my laptop was not working. All the forums were useless. They wanted me to READ about wireless networking !
Finally a good friend solved the problem in a simple way : it appears Ubuntu has not installed the drivers for my Broadcom wireless card since it was not open source. I had to download it myself. Here is how : Go to System menu on the top bar. Choose administration/ hardware devices. Tell it to activate the device. It will download the drivers through the cable attached to DSL modem and install.
Then clicked the network icon, selected edit connections, and entered my wireless network name and password. This solved all problems.
Why doesn't Linux give me a warning that the driver for something is not yet installed ? When I was struggling with the network setup wizard for the whole day, there was no clue about the missing driver.
I've RHEL and windows installed in a single system. First I've installed RHEL then windows xp. Now to install grub how do I enter into rescue mode without any CD/DVD? Do we have any option?

View 2 Replies View RelatedA while ago my harddrive kinda failed. I didnt notice untill I got "Grub error 17" one time when I was trying to boot my computer. The problem is not really that I couldnt log on to my computer, but rather that I have alot of important information on the computer I would hate to lose. At the time I used Ubuntu 8.04 and had reiserfs filesystem on the computer. I bought a new computer and decided to wait untill I could rescue the data before doing to much dmg to it. But I dont really remember if I tried something to fix it before I realised that it was the harddrive and bad sectors that made me get gruberror 17. Hopefully I didnt do anything.
Anyway. Now today I had some extra time, so I decided to dive in. I booted from a linux mint disk and used ddrescue to transfer all the rawdata over the network to an image file laying on an ext4 drive. Once there I used reiserfsck to try and repair the filesystem. After that i mounted the image file and tried to access the files. Thats where the probelms started. I could see the whole treestructure of the harddrive and everything seemed ok, but when i tried to open the files, none of the pictures, documents and so on could be opend, and when I tried to open stuff like MP3 files they played quite strange. Videofiles was really messy, kept changing resolution and was almost always just gray and green squares on the screen. I decided to use ddrescue and move the files from the image file and on to a clean disk. So when I was done I could mount the filesystem on the new disk, but with the same resault, so I did reiserfsck again, and when that didnt help I did a buildtree also. Still with the same resault. So I decided to investigate the data abit. Opening files at random trying to understand what had hapend. And I saw that some MP3 files (the easiest to open) was some kind of mixing between several difrent mp3 files. Some files wasnt even in the same folder, so it was probably just that the file pointer was pointing at the wrong data on the disk. I dont know how that works really, so I dont know how to go on.
So now to the question. How do I get the data back? Have I done something wrong, can I redo somethig? I still have the broken disk and can take data from it once again, but I want to wait to do that untill I really know what to do. I also still have the image file, and the disk with the copied data. I have a ubuntu 9.10 system at my disposal atm.
