I installed kde4 before 4 days, I installed and the drivers of my nvidia card and I had no problems with that. Unfortunately, yesterday, when I tried to install flash player for firefox and java, I had a crash and when I restarted x server (ctrl+alt+backspace), I tried to log in again and then a black screen for a second and back again to login screen. Every time I try to enter my login information, I have this problem, black screen for a second and then again back to login screen. Failsafe boot, also the same result. I also have boot the recovery mode but when I restared the same problem... Please help, I don't want to re-install the os. It must be a simplier way.

Re: log in problem
There is a log file at /var/log/Xorg.0.log. Open that and see what it says, toward the end of it -- there should be error messages.Comment

Re: log in problem
yes indeed, I opened the Xorg.0.log, and at the end I read this:
"Fatal server error:
Unrecognized option: Protocol
Xorg.0.log: 13: Syntax error: "(" unexpected"
Any idea about this

Re: log in problem
The phenomenon that you described (looping login never starts X) is sometimes referred to as "login loop". It has about 4 known causes. Since your problem started after a crash of some sort, let's try the easiest fix first. This one involves renaming the hidden folder ".kde" that is in your /home/vkot folder.
But wait -- you said KDE 4 -- is that a 8.04 system? In that case, you may need to rename the .kde4 folder instead.
So, here are the steps:
1. Open Konqueror or Dolphin and in View>Show Hidden Files, you put in an X so it shows all the hidden files/folders. (at the login splash, can you choose a KDE 3.5 session? -- if not, at the "$" prompt, use the mv command below).
2. Either with a right-click and "rename", or else in a Konsole window with the commandyou need to rename the file.Code:mv .kde4 .kde4_bak
3. Close all open windows, and restart the X server with Ctrl-Alt-Backspace. Upon restarting, you will be presented with your login splash. If the login works, you will see a clean desktop -- all customizations are in the backed up .kde4 folder. So, you can either reset your settings from scratch, or attempt to reconstruct them from the backed up folder. I haven't done that particular maneuver so you're on your own if you attempt reconstruction.
If this fix doesn't help, we'll look at some of the other possible causes of "login loop". If you search this forum on that term, you'll see some other posts on the topic.
