I have 3 HDDs and on /dev/sda1, I have Ubuntu 12.04 installed and also the bootloader is on the same disk. After GRUB when I select Ubuntu 12.04 to boot up it freezes just after the GRUB screen and before the login screen. Here is an image attached
This is how this problem started.
I have Ubuntu 12.04 and I installed cinnamon, it was working fine, until I updated the Cinnamon. Cinnamon's new update had some problems and it used to freeze a lot while I was working on my computer.
So I read some solutions online, and they dictated me to downgrade the
xserver-common package. I did that, and after downgrading the
xserver-common, I restarted, and this is what turns up.
It just won't proceed forward from this screen. I need to restore it to fully functioning condition, since I have made a lot of changes on my Ubuntu 12.04 which take about 9 - 10 hours of work and I do not want to redo them. So, re-installation is not an option.
Is there anyway I can get my OS working again. Also would the recovery mode help.I edited my GRUB default files in
/etc/defaults/grub for not to display the recovery mode. So, if you can tell me how to boot up the recovery mode using GRUB CLI, that would be great.
Also note, I cannot access tty1 on that screen and there wasn't any response, doesn't matter which button I press.
After pressing shift, I tried the GRUB menu, it still looks like this
That worked perfectly. I upgraded, the xserver-common. And then booted up ubuntu, it booted up to the login screen. But then it freezes. On the login screen. I cannon move the cursor nor the keyboard works. I can see the Ubuntu login screen, but I cannot do any thing. I tried going back to recovery but it bring me back to the same screen. I also tried failsafe graphics mode and still it brings me back to the login screen where it gets stuck.
