Ubuntu :: Screen Gets Garbled At Login Prompt?
Feb 26, 2010
I had received ununtu HH CD, which I loaded few times in few machine without problem (CD is ok). But in a perticular machine ubuntu HH, makes the screen garbled during installation and after installation at login prompt, but screen is just OK before the login prompt. This is happening in one machine and when i tried to load ubuntu 9 and fedora core in this machine, all goes fine (installation and use) means machine is reasonably ok. As I load edubuntu on HH, hence this ubuntu loading is important for me.

The mingetty --noclear parameter is failing with my current Fedora 13 installation. In the past this parameter would inhibit the clearing of the screen before prompting for the login name on the console. At present even with the parameter it clears the screen.
My /etc/inittab (which always worked past versions) contains:
Code:
Can someone tell me if I might be doing something wrong, or was this parameter dropped in the current version? Does anyone know of a workaround?
I understand the security purpose of the clear screen. But the particular computer is in a secured location. I prefer to look at the content of the previous screen for debugging and other chores.

Whenever I log in, the upper right hand corner is garbled, and there are small white rectangles. If I log out and log back in, the problem is fixed. Could someone please help me fix this?

I also have had the garbled screen problem when I exit X. I have fresh Slackware 13.1 64 bit install. I have no xorg.config file. The install process installed an xorg.config.vesa instead. Within X, everything is fine. I have the correct screen resolution and all software works great. Within the xorg.config.vesa file my monitor and graphics card have been identified correctly. When the problem first occurred, I experimented by renaming xorg.config.vesa to bad.xorg.config.vesa and using my backed up xorg.config from my previous installation of 13.1, 32 bit version.
When X started, it complained the xorg.config was not found. So, I deleted the xorg.conf, renamed bad.xorg.config.vesa back to it original name and rebooted. Then, everything worked fine except when I exit X I now am put into a huge font - I'd guess somewhere abouts 768x640, or less. It is no longer garbled. If I reboot, text mode comes up as it should with 1048 resolution and the penguin graphic sits on top. Then, X is still fine to work with, and kconsole works fine within X, but when I exit x I am always put back into this graphics free humongous font.

I just switched from xp on a HP s7613w (gforce 6150 le) to ubuntu 9-10. I can not see anything over 800x600 to select unless i enable the nvida drivers. There are three choices and i have tried them all, After i activate them it will let me select the 1024x768 that i need but the screen is garbled. There will be garbled text till i run the curser over the text then it will stratin up. The buttons on a page will move down and to the right a little bit when i put the cursor over them. When i uninstall the nvida drivers everything goes back to 800x600 and the screen is fine. My monitor is a Sceptre X20 is that helps. I am new to linux so please use easy to follow instructions if you can help me. I tried pc linux and it did the same thing. I like this version better so i am going to try to get it to work.

I upgraded my wife's old Acer Aspire 1350 laptop to Lucid Lynx, which works fine, except for the fact that the splash screen both when the OS boots and is shut down is completely garbled and unreadable. The screen is also unreadable when accessing a tty via CTRL+ALT+F2 etc. The GNOME desktop resolution is completely unaffected and is perfectly usable. The splash screen works on MY desktop PC, but it does seem to be using some strange video timings, as my monitor recognises it as 640x480 but doesn't seem able to centre the screen properly. I strongly suspect that this is the cause of problem and my wife's laptop display just does not like the video mode. If I plug my wife's laptop into my monitor, it displays OK.

After applying the latest round of updates last night, I turned on my laptop this AM (ATI X1300 Mobility graphics running the default drivers), selected the latest kernel in GRUB, and waited to log in....only problem is that instead of seeing a normal loading screen (Blue with Fedora icon filling in), I instead get a black screen mostly covered in multicolored rectangles. I don't believe there was a graphics driver update, so I'm rather confused as to what went wrong/how to procede. I can still boot using a previous kernel.

So this also happened to me when trying to install an old version of Ubuntu (hardy I believe). I have a Sun Netra X1 that I am trying to install the latest stable Debian Sparc64 port on. I'm doing a TFTP boot, and am able to get the kernel to load. However, once the kernel loads the installer, the screen gets garbled (attached is a screenshot from my console session) This server has no graphics card, so I have to install using the serial console. I don't recall having this issue when I installed the last stable version. Any ideas what's going on or how to fix it? I even passed the option "DEBIAN_FRONTEND=text" to the kernel, but it didn't seem to do anything.

I am completely failing to boot the Fedora 13 i686 live CD (MD5 check OK), in every case after the progress bar at the bottom completes I am presented with a garbled screen. My system has:
Motherboard: Asus MX-M2V
Graphics card: Gigabyte nVidia GeForce 7600 GS
2GB RAM, AMD64 dual core, etc.
Some websurfing this might be a graphics option and I have tried adding different commands to the boot option before the "quiet" namely:
nomodeset nolapic / nomodeset noapic / nomodeset noapci / nomodeset acpi=off / nomodeset xforcevesa
None of which worked. Both Asus and nVidia offer linux drivers for download:

I installed Ubuntu with a partition that was too small for any practical use, so I installed it again, thinking it would simply overwrite the other one as Windows would do. Obviously not. Now I have two Ubunto installations, neither of which work. I get a White Screen after the Ubuntu thing that shows its progress. If I try to boot from the CD, the Ubuntu thing works again, then I get a completely garbled screen which is totally unreadable and unuseable. I should also mention that I originally installed with a 19" square flatscreen from HP, but have upgraded to an Acer H233H. Since I have no clue what to do whatsover Ubuntu is just taking up space. I'd like to be able to use it, and I'd like to be able to get rid of one or other of the installations.

I just installed Fedora 12 on a laptop. I changed the default shell on the root account to /bin/tcsh and changed the runlevel to 3 and then rebooted. Now I can't login into the root account: it returns me immediately to the login prompt and I can't see any error message (the screen is cleared).Why is this happening?Can I boot into some sort of safe mode so I can undo my changes to the /etc/inittab and /etc/passwd file?I tried booting with a Live CD with the intention of mounting the filesystem and making the changes, but the new filesystem is a LVM and it won't let me mount it (or I don't know how to mount a Logical Volume).

My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.

I just went out and bought a 19" flat screen LCD monitor. Plugged it in and it is not working correctly. When I start the computer the bios info will show up on the screen, then it goes to the screen that let's you choose an O/S if you were to dual boot. After clicking "enter" it will show the first line of the boot then it goes off into horizontal colors then goes black. I have search many different posts and googled but nothing is giving me a hint at this.I changed the xorg.conf to match the refresh rates to match the monitor but that did not work, and did not really think it would considering the point this monitor goes out on me. running: 2.6.27.7-smp 01:00.0 VGA compatible controller:

I have installed VirtualBox and setup a Windows Vista host, initially with a .vdi of 10gb. That filled up quickly, so I added another 20gb secondary partition, after first trying to allocate a .vdi to a SCSI controller. Configured the drive in Windows (Computer Management), and all seemed ok. I shutdown VB, and rebooted my Linux host (openSuse 11.3). Now I keep bouncing back to the login screen, and can't login to Linux KDE, but can login to a console.I do have the following info:
/etc/fstab:
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part5 swap swap defaults 0 0
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part6 / ext4 acl,user_xattr 1 1
[code]....
I did see a message before, that I don't see anymore, that said it could not start NFS services due to missing entry in fstab. Another I'm seeing now is it couldn't start the avahi-daemon, no space left on device. This is odd, since I have a 200GB drive, with half of it left, only max 30GB set to VB. Here's my df -k output:
/dev/sda6 Use% is 100%
devtmpfs Use% is 1%
tmpfs Use% is 1%
/dev/sda7 Use% is 46%
So root "/" is mounted on /dev/sda6, which looks like it could be a problem, but why would this suddenly be a problem after working with VirtualBox? Could this be a matter of just freeing up space on /dev/sda6? Like the /tmp folder that's under "/"?

I don't get a UI login prompt at startup and it makes a sound. I'm using 10.04, though this did happen to me in 9.0x as well. When I press ctrl-alt-F1, I login and sudo gdm stop and do sudo startx this seems to put me at root and there is an error with the applets and the panel does not load. "Killall gnome-panel" does not fix it.
If I simply do startx (w/o going to root), it goes to a black screen and if I press ctrl-alt-F1 it repeats "No protocol specified" until I get the error message xinit: Resource file temporary unavailable (errno 11): unable to connect to Xserver.

I managed to change the background by copying over a new image file to some directory. However, there is still the big boring login window. Is there any way to change that? I'd like something darker, and smaller. I copied over the image file to /usr/share/backgrounds/warty-final-ubuntu.png My image file was actually a jpeg file, but copying it over to /usr/share/backgrounds/warty-final-ubuntu.png posed no problems.

This might be simple but i am unable to find an answer anyplace online. How do you change the terminal login prompt on a Ubuntu server?Right now when you go to log into the server it displays:<old_servername> login:
I would like it to just display login without the server name or the new server name. I am not sure how that info go in the login prompt to begin.

I have a desktop running Hardy and till friday it was running good. Today is monday and I guess it has got monday blues like I get every monday at work.Today I tried to start it as usual but it just refused to go further than login screen. I just can not login. It just hangs it there. I do not know what has gone wrong. I did not change anything since friday and no one else uses it. Theres nothing in logs that could give any idea. It just hangs without any reason and is still on the login screen for ever. It does ask my username and password but then it does not go further.But to my surprise I tried logging in with root and it gave me expected error that system administrator is not allowed to login from gnome.

Whenever I boot up my computer, Ubuntu (10.4) brings me to my desktop, then immediately displays a prompt to enter my login keyring. After some searching on the forums, it appears that this is because I set my laptop to auto-login. Am I missing something here, but what does auto-login have to do the the keyring? Why do I even need to enter that password? I understand that many Ubuntu users are picky about security, but why isn't their any option to disable this? It's almost as bad as UAC from Vista, which is one of the reasons I'm dual-booting Ubuntu in the first place. This is an annoying "problem" that has been bugging me since I first installed Ubuntu - how can I change it?

I installed 64 bit Lucid Lynx last week. There were some issues with the grub boot manager and my windows boot manager. However, about half the time i would boot to reach only a login prompt. If i used CTRL ALT DEL i would then reboot usually into the GUI.So now i only reach a login prompt all the time. How do i get the the GUI to run automatically?

I'm getting some weird behavior when I log in via ssh to a ubuntu server. When I log in, there is only a $ at the command prompt, no user name. The arrows don't work, they just put the arrow characters in the prompt. Everything else seems to be ok. Also, when I say logged in as User, I meant a new user I just created.

I click on the corresponding checkbox in users and groups but but it doesn't do anything. I also want to disable password prompts in general. Also when I try using Computer Janitor it says it could not complete and to check if other package managers are open, but none are.

How do I disable showing Usernames? I want to be prompted for BOTH un and pw. If it is necessary I could just change it so that it boots into a fullscreen terminal so that you would have to input "startx" and then username and password. Or I could just change it through gui or 3rd party software.
