i can`t log on to my Trusty 14.04 LTS

Does the system have a make and model?
Have you ran full updates?
What video chip does the system have?

Trusty is LTS but is currently prerelease so is officially unstable.

yes i have run full updates, one was partial, must say that...
 Motherboard is Gygabyte nVidia nForce 560 DDR2 800Mhz GA-M56S-S3, AMD Dual Core Athlon 64 X2.
Graphics card - GeForce 8500 GT 512mb GDDR2 Turboforce edition. NX85T series Graphics Accelerator.
Sound-Realtec HD Audio 7.1
Video - Leadtek WinFast TV 2000 XP Expert PCI 2.3 32bit.

all was fine untill last night when i got update for some video stuff, i dont know what they are for, Sorry...

system is x64 bit

If you run :

Do you only see an Nvidia GPU or do you see others?

Thank you...

Please Guys Help me, i can`t log on to my system due to the above mentioned problems, all help will be very Appreciated and Welcome.

                                                                                    Thank You guy`s in advance...

I assume that the output of the "dpkg -l | grep nvidia" command resulted in "...nvidia-cg-dev:amd64..." not in "...nvidia -cg -dev :amd64...". Please be careful not to add extra space characters when reporting the output of commands!

If the only output of "output of dpkg -l | grep nvidia" is "nvidia-cg-dev", then you just have a nvidia toolkit, but not the real nvidia display drivers installed.

Try the following:
Reboot your sytem in "root shell prompt" mode (see http://www.psychocats.net/ubuntu/resetpassword and follow the instructions up to issuing "mount -o rw,remount /").
Then issue the command

ubuntu-drivers list

You should see that there is a dedicated nvidia driver for your video card that can be installed.
Please provide the exact output of that command.

ok, Thank you very much sir.

Output is:

nvidia-304
nvidia-331-updates
nvidia-331
nvidia-304-updates
nvidia-173

                                                           Thank you sir.

Then try

ubuntu-drivers autoinstall

and reboot.

when i add the command: ubuntu-drivers autoinstall

output is:

W:Not using locking for read only lock file /var/lib/dpkg/lock
E:Unable to write to /var/cache/apt/
E:The package lists or status file could not be parsed or opened

                                                                                Thank you sir.

Run:

sudo mount -o rw,remount /

Then try again

when i add the command: sudo mount -o rw,remount /

and then: ubuntu-drivers autoinstall

output is the same as the previous time:

W:Not using locking for read only lock file /var/lib/dpkg/lock
E:Unable to write to /var/cache/apt/
E:The package lists or status file could not be parsed or opened

                                                                                                 Thank you sir.

It seems that your root file system is still mounted readonly.
Is there any output of the "sudo mount ..." command?

Dear sir, output is still same as previous time:

W:Not using locking for read only lock file /var/lib/dpkg/lock
E:Unable to write to /var/cache/apt/
E:The package lists or status file could not be parsed or opened

when i try to log on in regular way, it still displays the same white window giving me options to run system in low res mode
but when i press ok, nothing happens, neither option is not working.

                                                                                                Thank you sir.

That is not the output that I asked for, but never mind.

Try rebooting into recovery mode - command prompt. Log in with your name and password and issue the "sudo ubuntu-drivers autoinstall" command.

Please inform us about any warnings or error messages from that command.

unfortunately output is same as previous one:

W:Not using locking for read only lock file /var/lib/dpkg/lock
E:Unable to write to /var/cache/apt/
E:The package lists or status file could not be parsed or opened

                                                                                                     Thank you sir.

in recovery mode, when i press an up arrow and issue command:gk sudo gedit/etc/lightdm/lightdm.conf

output is:(gksudo:814):Gtk-WARNING**:cannot open display

                                                                                       Thank you...

Please can somebody provide some Help Please.

                                                                                      Thank you all...

Does anybody have a clue how to resolve this problem?.

                                                                                          Thank you.

ok Guy`s...this is a third time that i have installed again Trusty 14.04, it seems it`s not Trusty at all, must say, i`m literally afraid
to install updates because i never know will my system will go up on next boot, i was thinking that unstable means minor fixes, not reinstalling again, again and again, because of huge experiments with "LTS", and i thought that here are some hard core tuff coders that are willing to help a new guy to overide some troubles, but again i thought wrong...but i still want to see how you guy`s will do a workaround concerning this bug, i still hope there is an someone who is competent to solve this problem...

                                                             Bravo and Thank you guy`s for your care and dedication

If you are booting in recovery mode - root command prompt and then execute the command

mount -o rw,remount /

exactly as written here, and if you then still are having a readonly file system, then you are doing something so much different from what we expect that I do not know how to continue.

Can you please try this again, and then issue the command

ubuntu-drivers autoinstall

and tell us what happens.

Dear sir, i don`t have nerves to wait several day`s for help, i have work to run, i have installed a whole new Trusty 14.04 and all software that i need including ones that run over Wine app, i have installed over 300 programs and whole new system because my customers dont have patient and they dont have to know about my problems, they need output only and quality one Dear sir.

    Greetings for you and Mr.actionparnsnip for true dedication, Help, courtesy and real commitment to a thing called Ubuntu.

                           Thank you from my heart and soul, people like you two guy`s deserve all the best in this world.

And to answer to your question about issuing provided commands, before i have installed a whole new system i already did exactly as you told me now and before, and output is:

W:Not using locking for read only lock file /var/lib/dpkg/lock
E:Unable to write to /var/cache/apt/
E:The package lists or status file could not be parsed or opened
