Ubuntu :: Couldn't Use Grub2 Console Prompt To Log Back - Can't Get Anything To Work Correctly
Feb 1, 2011
Is this a beta version or something? I installed this version because it came as a live cd coupled with emc2 for cnc machining. I cannot get anything to work correctly. I tried to install Mozilla thunderbird using the application manager and it is very slow. It takes forever for the menus to open. or emails and is virtually unusable. I tried to use the startup manager and it killed my grub bootloader so I needed to reinstall. I couldnt successfully use the grub2 console prompt to log back into linux even though I ollwed several tutorials for this. I tried to install the flash player plugin and it kept telling me still to install it before I could watch flash videos even though I had installed it 3 or 4 times. I just tried to install evolution mail and it cannot log into my gmail account. I tried to install swift dove which is a faster version of thunderbird and it says it is starting but then never does. I am reasonably sure I should hang in there as I have heard Ubuntu is very good as an os.

After upgrading to Ubuntu 9.10 I no longer get a login prompt when switching to console mode e.g. (CTRL+ALT)-F1. Instead i just get blinking cursor in the top left corner. Key strokes are printed the screen but otherwise nothing happens. I can switch back and forth between X and the console normally.
Where are the consoles configured, and is there a corresponding log somewhere i can check? Has anyone had similars problem?
My system is an old Amilo Pro laptop with a VIA 800 compatible chip-set.

I installed Ubuntu 10.10 on my 32gb flash drive. Just one large partition for the OS and about a gig for swap. Worked fine. Booted to USB on two computers and a laptop at home. Fine. Figured I'd try it on a work pc for the sake of testing a random computer. Well I stick the drive in, boot up, select usb from the boot menu and bam Ubuntu starts loading. I look away, it's cool ubuntu's loading. Well I turn back and it's a black screen. It's "<username>@whatever login:" or something close.
I use the username and password I created during installation and what I used to login to the computer like fifty million times while booted into Ubuntu. Well, invalid login. The first time I installed this OS on this drive I updated it through the update manager and rebooted. Next thing I know I type in my username and password, hit enter, and bam black screen, some stuff, then im asked to login again. Now after this next iteration I am faced with yet another faulty login screen. What is up with this OS?

I have a question about the prompt. it is very easy to tune it for it to be colored and display path where you are etc. But my problem is that when the path is too long I would prefer the code line to be on the folowing line...
Ex
11:00 me@host a/short/path > ls -ltr ./stuff
11:00 me@host a/very/very/very/long/path
> ls -ltr ./stuff
and to be honnest as I am very new in LINUX I don't know how to do this...

Ubuntu has stopped booting correctly. Now it shows the Ubuntu logo and then, instead of GDM, it shows a console login prompt. How do I go about troubleshooting this?'m in Windows XP (which I like a lot better than Ubuntu, because it actually works) but all my files and work are on my Linux partition.

How to change the console login prompt settings in slackware 13.1 x64? I tried googling but couldnt find anything, maybe I dont know what it's called.. I mean when the system boot and boots into console asking login info, how to reset the console to new page/clear screen(clearing all the boot up info lines) before it prompts to login. Like for example if after logged into a tty I type exit, I want the screen to refresh(reset?) such that all screen info is cleared and only login prompt is shown on the top left of the screen, like in fedora shell prompt.

I finally got my system to boot to a console prompt. This is a fresh installation of fc10 that I have struggled to get working with my old Adaptec 2940 scsi hardware. I am a little fuzzy on the whole gtk, gdm, gnome thing. So how do I go from this console prompt to configuring the new installation with desktop?So let's say I am logged on as root on the console.

I run a number of Ubuntu 9.10 boxes attached to multiple daisy-chained KVMs. None of the PCs are using any GUIs - they all run in console mode. I often reboot them remotely via an SSH session, etc. If a monitor isn't actually active on the PC when it reboots, Grub2 uses a low-res video mode, despite having a higher-res video mode set correctly in Grub2's configuration. If I reboot WHILE THE MONITOR is attached to the Ubuntu PC via the KVM, the video mode is set correctly as configured in Grub2's config files. If I reboot WITH NO MONITOR attached, the video mode is ignored and I'm stuck in a low-res mode next time I attach to the PC via the KVM. How can I force Grub2 to honor the configured graphics setting, despite not having a monitor present at the time it boots?

I installed 2.6.38 from backports. It boots OK, and among the start-up messages it says it has started kdm, but then it offers only a console login prompt, no GUI. I assumed (perhaps optimistically?) that newer kernels would be backward-compatible, and that any dependencies on other software would be enforced by the package mechanisms. Running amd64, Squeeze, KDE.

what the following means and what I can do, if possible, to fix it:
Code:
Couldn't reference dri2 back buffer handle 0x00000002: No such file or directory
Segmentation fault I know what segmentation fault is, but the rest is a mystery to me. This is on OpenSuse 11.3, 64bit.
I get it from some games I installed for the kids to play, but obviously they can't until I've managed to fix that. It happens in Ppracer and Super Maryo Chronicles, and the games worked fine in 11.2. Same graphics card too, and the same xorg.conf file. DRI is enabled in that config-file.
The gfx-card works fine otherwise, and it's an Intel G33 GPU. I do get some lock-ups now and then, but I'm not sure if it's the gfx-card/driver or something else.

I am using the latest UBUNTU 9.10. It was working great. I logged in as Tom, put in my password and could do what I needed to do. Now when I go to the CLI through the terminal I get "Tom@new-host-2:~$ " which has no privileges. I obviously messed up something. I can't find a way to get back to my original prompt when I access the terminal.

I have a Asus EEE PC 1005P which I installed a Command-line system on using the Alternate Installer CD of Ubuntu Lucid Lynx. I do not have (or want) the X Window System installed.
I want to change my console screen resolution (not inside X) to 1024x600. But it isn't reported when I use vbeinfo inside grub2:
Code:
grub> vbeinfo

After an update on squeeze about a week or two ago, my console font turned green. I'm not exactly sure of the timing, because I switch between lenny and squeeze, and some time passed between the update and the reboot in squeeze.
During the update, I was asked if I wanted to keep my altered /etc/grub.d/00_header or take the package maintainer's version. I took the PM's version, knowing I'd lose my edit (set gfxpayload=1024x768x16). When I add that line to the new 00_header, run update-grub and reboot, the console font is the size I want, but it's a dull green. Reminds me of my first computer. How do I get it back to white and keep the 1024x768 resolution?
Currently booting with grub-legacy and chainloading grub2. If I boot entirely with grub-legacy, and pass vga=791, the console font will be white. It doesn't matter which kernel I use. Currently, I'm running 2.6.32-3-686. Same behavior exists if I use 2.6.30-2-686. If I use 1024x768x8 I get a dull gray instead of dull green.

Does it mean I have the driver? how to set it to 1024 x 600 in grub2?

i have noticed that if vista is not the active partition, hybernate does not work. it just goes black and then back to the user icon screen to log back in. another "slight" problem was that i was not able to apply a service pack. after restoring vistas dominance i was able to install the pack. is there any other work arounds for hybernate? even though you might not be interested in cleaning up after microsoft.

I'm trying to run 'grub-install /dev/sda', it stays stuck on 'Searching for GRUB installation directory ... found: /boot/grub' after leaving it for an hour, nothing happens. I have tried removing all Grub related packages and installing grub-legacy several times, to no avail.
The machine is quite an old one and is an offline sandbox for a friends kid who likes to tinker with older OSes. The hard disk has failed in it so I have donated an old drive to get the machine back up and running for him, as the menu.lst is a lot easier to modify than the newer grub.cfg, he would like the older grub back.
I've done a few searches particular for Debian 8, but the closest I can find is for Ubuntu here, [URL] ....
I have tried to use both the grub rescue disk and the command line listed in the link above.

I was yesterday evening experimenting inserting a script into /boot/grub/grub.cfg. Well I broke grub.cfg and had to try to boot from a grub2 prompt.I have separate /boot and / partitions on /dev/sda1 and /dev/sda2 respectively.Working out the correct syntax for the boot to work was a little complicated, so I thought it would be useful to post the correct procedure here, in case anyone else has the same set up that I do (separate /boot and / partitions)At the grub prompt code:
grub> set prefix=(hd0,1)/grub
grub> insmod linux
grub> set root=(hd0,2)

I have about a half dozen different names/passwords for Ubuntu but none will work to log in. How to get out of this text console and back to Ubuntu GUI? And, how to read my lost LogIn name and password for this "Text Console"?

I have a problem with my acer aspire laptop and The screen is like completely black i mean if you hold a flashlight to a certain spot you can see a tiny bit. i was on another thread earlier and the posted this "This fixed a black screen issue and a brightness adjustment issue after installation of ubuntu. Also on 11.04 I couldn't get Unity to work until I edited grub I didn't come up with the fix but it took me forever to find a solution so I figured I would post it. If I have did something wrong just get a mod to delete or move this. I don't use forums often.

I finally understand why I couldn't get Clonezilla to work on my system. But, I am more baffled than ever.
You see, my system has been in great working order for months. I am running 9.10 32-bit and I keep everything maintained on a daily basis. I just updated to kernel 2.6.32-19 and, like I say, everything is working pretty much perfectly. But, yesterday, I volunteered to help with some official Canonical Ubuntu testing. This morning, I got an email from them that they want me to do the work and giving me instructions on how to proceed. The first thing to do is free up some disk space in order to have a special partition on which to install their testing kernels.
So, I downloaded their suggested tool for doing this, gparted. And, when I ran gparted, the first thing I discovered is that my disk drive has absolutely nothing on it! No partitions, at all. It only sees an empty device, /dev/sda. This is exactly what Clonezilla told me a couple of months ago - no partitions could be located to be backed up.
However, I and Ubuntu think I do have partitions:
Code:
$ df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda5 ext3 19G 1.5G 16G 9% /
udev tmpfs 502M 360K 501M 1% /dev
none tmpfs 502M 204K 501M 1% /dev/shm
none tmpfs 502M 328K 501M 1% /var/run

I installed Mangler and one of its requirements was pulse-audio. I installed pulse-audio everything worked great except i couldn't get sound out of wow if i started mangler first and vice-versa. I then found a version of Mangler that worked with alsa. So i uninstalled mangler and pulse-audio, installed mangler-alsa. Everything works great now. The problem is when i uninstalled Pulse-audio i lost all my sliders in Yast > Hardware > Sound > other > volume. The only thing that shows up is master volume > Test. My sound works great just can't adjust anything. How do i get my sliders back. I would like some advice before i screw something up. (lol) My Sound card is according to sound configuration SBx00 Azalia(Intel HDA) - Driver snd-hda-intel.Opensuse 11.2 KDE 4.3.5

I switched over from Ubuntu because I realized Ubuntu sucks now (lol), but anyways... Now I'm trying to get Grub2 to boot up properly, but this "xputs" error pops up and drops me to the recovery prompt. I tried the grub-install dev/sda and all it did was recognize my Windows 7 OS (as Vista) and added it to the bootloader list and didn't fix the "xputs" issue.
I heard that doing a chroot is the most effective solution. Forgive me, but I don't know what "chroot" means or how effective it is. I can specify more information about where the OS is if needed. I have the boot flag set to the Debian OS at the hd(0,5) or sda5 I think, and Windows is at sda1 (I think). I just want to make sure I can fix this without damaging Windows, and I'll try to get more information.
Right now, I can only get into Windows or Debian with UBCD and Grub2 Super Disk and I know that sometimes Parted Magic could orderly mount the disks differently, so I don't know if it was sdaX or sdbX, but probably sdaX. I'll check again.

I've made a Debian installer CD using a netinst image some time ago and tried to install it my self, but I couldn't get the X system to work, and I wasn't sure If i made the correct actions at partitioning the drives etc
My primary OS is Vista, but I want to dual boot with Debian. I have two large drives, C: and D:. D: now is not visible from Vista as Debian is installed in it and it's the drive that I want to install debian in it. I was using grub to select OS, but when I decided to ask for your help, I wanted to format the D: drive. While trying to find a way to format it (it wasn't accessible by windows), I deleted the partition so grub was giving a 22 error and I couldn't boot my system. Finally, I've fixed that and now I want help to format D: (if necessary) and then install Debian with a Graphical User Interface in D:, but keep Vista in C: also. I have the Debian Installer CD, but I don't want to proceed alone, as I don't understand everything at the partitioning state, and I don't want to do something wrong and mess C: (or the entire machine).
