Bug Description
Binary package hint: gdm
Ubuntu 10.04
GDM 2.30.0-0ubuntu5
On 07/05/2010, I upgraded from Ubuntu 9.10 to 10.04.
When I tried to boot, I had problems at the login screen:
I get either of the following:
. A locked screen with no mouse or keyboard capability. So I press & hold the start button for 6 seconds to stop the PC.
. The screen is not initially locked, but after I select my user & try to enter my password, It either locks up as above or it locks up & keeps looping through saying the user/PW combination is not valid (sometimes filling the PW line with dots).
Once, it worked perfectly!?
So, from then on, I booted using the fail-safe mode.
The install went reasonably well. I did not take the option to include updates at the same time.
I did accept to allow the upgrade tool to delete all suggested files (I don't know what most of them were for, but I was happy to get rid of a lot of old kernels, etc.). This deletion may have been the reason for my subsequent problems.
I thought that the missing updates would help, so allowed those to be installed, but the problems persisted.
From reading other posts, I gained the impression that this login problem may be caused by the graphics driver.
I am not a skilled Linux user, even though I have been using Ubuntu for 4 years. Some of the following comments may suggest that I know what I am doing, but I don't, & have been spending many hours searching for a solution over the past week.
I now know that I have a 5-year-old ATI graphics card. However, at one stage during the boot, it said to configure an NVidia graphics driver. This didn't help.
Hardware Driver didn't help, as it merely comments "No proprietary drivers are in use on this system".
I tried to work out what was wrong with the graphics driver, & soon realised that it was set up for the wrong card type.
After lots of searching files, I thought fglrx might be the solution, & downloaded that (even though ATI said that the legacy cards support stopped over 1 year ago). It didn't help.
I then noticed that there was no /etc/x11/xorg.conf, only backups & failsafe.
So I copied failsafe to xorg.conf, & changed the driver to "radeon". This didn't help.
I did try the "reconfigure graphics" option that comes up when using the fail-safe mode.
I changed the driver to “fbdev”, but this didn't help the login problem, so I changed it back to "radeon". I still have HD graphics (from using the failsafe boot), so I think that I will stay with "radeon", as it seems to be the right driver.
[The other problem that I had had is that there was no network connection for 2 days. I use a cable connection, but instead of the "wired" icon on the top right corner, I had the "wireless" icon!? from checking on my Mythbuntu (9.10) PC, I determined that there was nothing wrong with my router or modem or ISP...]

I forgot to mention above:
1. After signing-on, the following message appears: libconf2- 4/gconf- sanity- check-2 exited with status 256)".
"Message: There is a problem with the configuration server.

2. From the fail-safe options, I can get a good login screen from either selection:
. Run in low graphics mode for this session only, or
. Restart X.
