ubuntu installation troubles and video help

you say you are new to Ubuntu so while you are waiting for a good answer
please take a look at this useful Ubuntu manual http://ubuntu-manual.org/

Can you give the output of:

lsb_release -a; uname -a; dpkg -l | egrep 'flash|gnash|swf|spark'

Thanks

i dont know what that is

These are commands in terminal .

You can open a terminal with Ctrl+alt+t combination keys .

Then copy from here and paste to terminal the command that @actionparsnip gave you.

++++++++++++++++++++++++++++++++++++++++++++++++++
lsb_release -a; uname -a; dpkg -l | egrep 'flash|gnash|swf|spark'
++++++++++++++++++++++++++++++++++++++++++++++++++

when you press Enter it will produce a result(s) . Copy and paste here all the results.

Thank you

Hi ,
try to install (or reinstall) ubuntu-restricted-extras.

give in terminal this command

++++++++++++++++++++++++++++++++++++++++++++
sudo apt-get install --reinstall ubuntu-restricted-extras
++++++++++++++++++++++++++++++++++++++++++++

it will ask for your password, write it carefully cuz it will no show anything(like you not write ,it is a matter of safety).
When you press Enter a bunch of stuff will appears for installation , it will ask you for confirmation , write y(es) and press Enter to begin the installation process. When installation completes reboot your PC and see if video and sound works.

Thank you.

here it is

Hi ,
I cannot see anything weird in your results. I see that you use the radeon open source driver for your graphics card.
Did you try to install fglrx (closed source AMD's driver) ? If you want to try it , open a terminal and
++++++++++++++++++++++++++++++++
sudo apt-get install fglrx fglrx-amdcccle
++++++++++++++++++++++++++++++++

reboot to see if things work better. (or worst)

Second suggestion : Try to use unity-2d. From the login screen at the login box , you will see up right a symbol like gear, click it and from drop-down menu choose ubuntu-2d and then login with your username and password. (ubuntu-2d is much much lighter)

Third suggestion : Check you HDD for fail messages.(hopefully not fails)
++++++++++++++++++++++++++++++++++++++++++++++++
sudo apt-get install smartmontools --no-install-recommends
sudo smartctl -a /dev/sda
++++++++++++++++++++++++++++++++++++++++++++++++
give the results of 2nd command here.

Thank you

well i checked it a gain and it finally worked thank you so mu ch for helping me!!!

Thanks NikTh, that solved my question.

Ok ,
and your HDD is in perfectly form . Good for you.

Glad we sovled.

Thank you.

hey umm i tried my computer again today and the problem is back

No problem , I don't know if you can Un-Mark the problem from being solved , if not , then open a new question.

We can try again to solve your problem. It will be a good point to link the question here (on your new question I mean) so others can see what methods or workarounds you used.

As a last effort to this question , try to update your system..
++++++++++++++++++++++++
sudo apt-get update
sudo apt-get dist-upgrade
++++++++++++++++++++++++

And try to re-install the AMD graphics driver
++++++++++++++++++++++++++++++++++++++++++++
sudo apt-get install --reinstall fglrx fglrx-amdcccle
++++++++++++++++++++++++++++++++++++++++++++

Thanks

nope it still does not work

Hi ,
are you going to open a new question , or you want to try to solve it here ?
If you open a new question I think it might be better , cuz more people would involved.

Your call

Thanks
