12.04 clean install now only get "input not supported" msg


Had dual boot XP & Ubuntu 10.11. Now finally getting rid of XP.

Did clean install of Ubuntu 12.04 using entire disk.

AMD Athlon 64X2 5200+
1.9 GiB RAM
500 GiB free HD space

After initial install, password entries were not accepted, they were defined as "invalid password".

Now when booting up I see the MSI Motherboard V-Class screen flash up, (I can get into the bios setup there) but after that, all I get is a box slowly bouncing across the screen saying "Input not Supported"

I have a NVidia GeForce graphics card. I suspect that this may be causing the problem. I have seen some have problems with the nvidia drivers.


I tried F6 during boot splash screen so I could use nomodeset, but F6 gets no response.

I don't know how to address the issue since I cannot get to terminal.

I tried the Demo feature of the 12.04 CD and opened terminal there.
Then I did this in Terminal:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current

But, as far as I can see, that did not change anything.

What can I do from here?

If you have an usb keyboard you could try a PS/2 one if it's a driver issue

I had this same problem when I installed Ubuntu 11.10. Googling for a solution I found a site which indicated I would need to remove the hash mark (#) from the front of this line in /etc/default/grub file. This worked for me.

Quote:
#GRUB_GFXMODE=640x480
Boot from the installation CD, mount the partition and navigate to the grub file above and open a text editor: sudo gedit /etc/default/grub and make the above change and Save. Reboot. You will probably still see the Input Not Supported and need to update Grub so, when you see the "Input Not Supported" window, hit the down arrow key on your keyboard ONCE then hit the Enter key. Some info will scroll up the screen and you should then get a window with several options:

Quote:
resume Resume Normal Boot
fsck Check all filesystems
remount Remount as /read/write and mount all filesystems
root Drop to a root shell
Use your keyboard down arrow key to move down to remount and hit Enter. You should get a new window with several options including update-grub which is the one you want to select. When you have highlighted it, hit Enter again and you should see some text scrolling by with whatever systems it finds. You should then get a message saying Grub is finished, hit Enter again. You should then be back at the first screen and select Resume Normal boot and hit Enter.

I'm not sure of then reason for this but I also have an Nvidia graphics card so...? The above was on Ubuntu 11.10 so I'm not sure you will see the same options on 12.04. I also had this problem with Mint 12, same solution, and the options were a little different.

STUCK AGAIN:


Edited /etc/default/grub saved file and chose "update grub" then computer locked up and nothing else happened even after more than 30 mins.

Then I did some things that seemed to solve the problem:

"Try Ubuntu" option from a 12.04 LTS i386 32 bit live CD and then chose "Install Ubuntu 12.04 LTS" from the Desktop.

did not install any updates or 3rd party software while installing.

After entering user and password

Chose "log in automatically".

Did not "encrypt my home folder"

Restarted when directed

When Desktop appeared (Ignored 3rd party drivers available notice, I did this once and ended up with black screen after restart) wait until "Update Manager" shows in the HUD with 100+ available updates.

Start and apply updates

Reboot and everything seems to work normal.


After using Mozilla, Terminal, and File Manager for about 20 minute, I the image on the screen would lock up at times.

So I checked if there were any proprietary drivers needed. The Nvidia ones were missing, so I activated the recommended one.

Restarting results in just a black screen, after the MSI Motherboard splash screen.

So now I am STUCK AGAIN.

Temporarily loaded Windows Vista to see if it had problems.

After 20-30 minutes of use it starts crashing, usually when starting a new program.

Device Manager shows some hardware is not installed.

Network adapters
Teredo Tunneling Pseudo-Interface

Sound, video and game controllers
Multimedia Video Controller

I have no sound - Vista says speakers are not plugged in.

Graphics Card seems to be having a problem so I am replacing it.

Will update after that

I had this "Input Not Supported" problem today after a Xubuntu update (12.04).

To start off, if you can see the Grub menu (with choice of kernel/OS, etc), then your Grub graphic mode is working okay. Otherwise, adjust:

GRUB_GFXMODE=1280x1024

in /etc/default/grub to suit your video hardware, run grub install, then reboot.

After Linux boot starts (we're done with Grub now), this line in /etc/default/grub is what sets the video res.:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ... nomodeset video blah 1280x760x=-blah blah blah"

After wasting an hour of my life I'll never get back, trying different settings of this one line, I said screw this and erased the whole thing:

GRUB_CMDLINE_LINUX_DEFAULT=""

When I booted with that, voila!, it all booted very nicely as if nothing had ever gone wrong.

You see, I had a bunch of crap in there from previous attempts last year to get Plymouth splash screen to work. Never did work, prob. due to my pesky Nvidia adapter.

So now I just have "quiet splash" back in there -- but nothing else. The "quiet" suppresses the boot messages and "splash" enables the default splash screen -- in my case that's not much bec. Nvidia and Plymouth don't seem to like each other. Works nice on shutdown however!

So this week's Xubuntu update broke the boot for me. But I think it means that the nice Xubuntu/Ubuntu folks fixed things -- it was my complex boot parameters that screwed things up.

BTW, if you're ever in this situation again, once you can see the Grub menu, you can actually try things without using the shell/editor/grub-install. Just go into Grub's edit mode -- see the bottom of the Grub menu screen -- letter e. Modify settings in the "linux" line there and your new settings will be used to boot (but not saved anywhere for next time).

Here's some good info about Grub settings:
