[SOLVED] natty install: no video output

[popol]

Hi

I've got a Packard Bell Easynote TH36 laptop on which I initially installed kubuntu 10.10 without problem: installation went out of the box, my only problems concerned graphics, such as difficulties seeing a video fullscreen.

I recently decided to upgrade to natty.

First using the update manager: everything went fine until I was asked to reboot: then nothing, the screen turned black and nothing else happened.
I then tried a fresh install from a CD. Again very difficult, the screen turned black immediately after the first menu when I select "start kubuntu".
After some search on forum and kubuntu official support, I was adviced a workaround:

http://ubuntu-tutorials.com/2010/05/...up-workaround/

Here is exactly what I did:

-boot from CD
-hit F6 and ESC to disable the popup menu, then manually edit the boot options: remove "quiet splash" and insert "i915.modeset=0"
-The computer boots and I can try natty and then install it.
-At reboot on disk however, again the black screen. The computer yet starts as I ear the startup music.
-I supposed I had to insert the i915.modeset=0 boot option within grub.
-So I start from disk, hit shift to display the grub menu, then e to edit, add the options to the boot line, then F10 to start
The problem is yet unsolved: still black screen and no possible console login, although the computer starts (music again)

Strange enough, a lucid install went without this problem, but with no wifi however...

Please help, this lasts for 2 weeks now and I have to used a very old spare awfully slow spare PC!

In case this helps I attach the log of lshw (I could run it after the lucid install)

thanks in advance

Re: natty install: no video output

I have a similar problem. I cant get the OS to play music or video files. when I double click on any such files, the OS prompts me to download some plugins. however the OS is unable to download them.
I am using Kubuntu 11.04 with win XP.

Sorry for disturbing and letting you read my poor English

After a night of intensive search, I've found on the 8th page of this forum a related topic and could save the problem.
Solution is:

-Install natty from CD. Prior to install, at the first menu, hit F6 to allow for more options, and select nomodeset, then start install
-On reboot after succesfull install, hit SHIFT to have GRUB menu, e to edit the commands, insert "nomodeset" right after "quiet splash" options.
-Once you are logged on, edit (with sudo) /etc/default/grub and add the same option.
-Run sudo update-grub

that's it

Well just a couple of comments

-to shihan3: I don't think we were talking about the same problem: I had nothing on the terminal (neither X nor console) on reboot, although the startup music told me the computer had correctly started. So I was not able to double click on any file!
-I imagine a newcomer to Linux having this problem at install: he would immediately give up and that's a pity. I don't know what is the reason for the problem but it really shoumd be fixed. I still don't understand why we have this with natty, all was working properly with lucid and maverick.

Thanks again for those who tried to understand me!

Popol,

Did that fix your issue? I am guessing it has something to do with the video card on that Packard bell. I had no idea they still make computers. I sometimes have issues with some laptop chipsets and video cards, especially odd ones. But I hope that fixed it for you.
