So I run Ubuntu 14.10 on HP Pavilion g6, i5 and with Radeon HD6500. Yesterday Ubuntu crashed and since then I can't get anyfurther than the log in screen. Ubuntu simply stucks with only the background and cursor visible. It seems to be stuck in log in and there are a lot of fixes all over the internet for this. Non of them seems to help. I will explain step by step what I done so far.
Update 1 dec 2014: Followed recommendation from @ash and didn't fix the problem. Still think @ash fix will solve similar problems, but not for me. I reinstalled Ubuntu and that fixed the problem, so the problem was probably graphically. If anyone have any idea what may have happend, please answer.
- Changing dm
First I tried changing dm to gdm (also suggested in a comment here).
sudo dpkg-reconfigure gdm
That didn't work. I even tried
lxdm, but no result there either. After I tried that I read that I might check
50-ubuntu.conf and did so. Nothing strange over there. Also tried
lightdm, no result. Then I found this and tried
sudo dpkg-reconfigure gdm sudo apt-get remove lightdm* --purge sudo reboot sudo apt-get install lightdm* sudo dpkg-reconfigure lightdm
I'm was not a fan of the hole
lightdm* --purge but tried it anyway. It didn't fix my problem, but I guessed it would remove a lot of packages that wasn't really related to the problem. What I didn't guess was that it would change the graphics this much. I could of course realized that
install lightdm* would install a lot of unnecessary packages. When I rebooted the computer it said Ubuntu Studios instead of 14.10 and the log in screen looks messy. Also, the computer gets stuck in a black screen with only the cursor visible instead of as earlier. Well, stupid of me to take a bad advice (if anyone have any quick fix for this I would really appreciate it).
Anyway, nothing of this fixed my problem.
- Reinstalling Unity and ubuntu-dekstop
lightdm I tried to remove and install Unity and the same with ubuntu-desktop, but no change. This is also a pretty common recommendation all over internet.
- .Xauthority related solusions
Next step was to follow this advice entirely, but the output of both
ls -lah and
ls -ld /tmp checks out.
Next step was this advice and it didn't do anything either.
I don't really understand what both this commands are trying to fix, but would be nice to understand that. Does someone have any further suggestions related to this? And does anyone have any explanation what they are supposed to fix?
Next step was to keep on guessing and this point I thought that the problem was graphic card related. I tried to Google around as much as I could about Radeon graphic cards and similar problems and found a solution that suggested:
sudo apt-get update sudo apt-get upgrade sudo apt-get install fglrx sudo aticonfig --initial sudo reboot
Well didn't do anything other than installing fglrx.
- So I'm looking for other solutions
This seems to be the four most common solutions to problems like this. I think it's time to at least stop suggesting anything related to
lightdm because that doesn't seems to do the trick.
As stated in comments this problem can be almost anything, but at least I tried to explain what I done so far. Have I done anything wrong? Are there anything more to know about these four?
