Hm? Never saw that error message... ([drm.intel_enable_lvds] *ERROR* time out waiting for panel to power on)

Are there any messages _above_ that?
Have you tried "Recovery Mode" yet? ("Advanced Options" in the boot menu)
Or an older kernel? Since you say it did work until recently.
No it doesn't.
when i give password it goes to root terminal,
It goes to "emergency mode".
No, it doesn't run perfectly.
hear i type startx command which runs perfectly and gets me into root account where i can use my system.
Most system services are not started at that point.
Right, because X didn't even start.
But i want to use my user account to login so exited from root account(shutdown the system and restarted to get above error) . when i press ctrl+f7 it gives me blank screen, nothing works in this screen except a cursor blinks.
You are in emergency mode, i.e. runlevel1.
As I already indicated, running "startx" doesn't work as a normal user, and you shouldn't use it anyway.
So i get back to above error by pressing ctrl+f1 and re login by giving password. so what i did next was gave following command su "user account name"
and used startx command and i got following error
Search the forums if you want to find out how to use it, I don't want to write it over and over again, and I already did once more a few days ago.
And it won't really help you anyway.
But: you should rather start X by switching to runlevel 5, i.e. leaving recovery mode.
You probably have to fix the actual reason why the system drops to emergency mode first, to make that work.
systemctl isolate graphics.target
But then the system should boot to graphics mode anyway.
Ok. But at that point /home is not used at all anyway.
1) In Home partition i got more 40gb space
Although if it fails to be mounted, the system will drop to emergency mode, too.
Do you have free space on your / partition? And what about /boot if you have a separate one?
If that intel error about the panel is the reason for your problem, it might be caused by stuff missing from your initrd, probably because /boot ran full when installing a kernel update.
Again, you are _not_ logging in at all.
2) Apart form root im not able to log in into any other account. Firstly i am not able to see login screen at all, after starting system, it directly leads a terminal with above stated in first quote
You have to type in the root password to enter emergency mode. Something important fails during boot so the system switches to emergency mode.
Of course. This is all moot if you are in emergency mode.
3) I did Ctrl+Alt+Backspace twice in blank screen( sreen which appeared when i press Ctrl+Alt+F7) nothing happened.
4) No one else touched by system except me, and i havn't changed my screen resolution.
5) No iam not getting and terminal screen when i press Alt+f2
No X is started, so all of the above doesn't make sense.
