i ordered an original Ubuntu 12.04 LTS cd which arrived.
I followed the steps in: http://ubuntuforums.org/showthread.php?t=1743535
Since I also have a graphic port on the main board i removed the nvidia card when trying to install 12.04 LTS.
I set a cross on nomodset and i added in the boot line:
Then installation run smoothly and everything worked.
I then readded my nvidia graphic card into the PC.
NOW when i login into Ubuntu 12.04 LTS it always freezes after 2-5 mins, sometimes it also reboots. (It also did so without the graphic card in the PC.)
I am currently not using the Nvidia card.
I don't know what todo as I read tons of posts but couldn't find an answer to this issue.
I also did a memtest and no issue with memory. Also it did run stable and well when doing the installation.
What do you suggest I try ?
After an hour or so
result: 3.2.0-40-generic-pae #64 -Ubuntu SMP Mon Mar 25 21:44:41 UTC 2013 i686 i686 i386 GNU/Linux
Next Step that i tried
I tried to follow the steps shown here:
Once 12.04 LTS loaded i did Ctrl+Alt+F1 to get into the terminal and then i carried out:
This gave no result. I pursued with:
sudo service apport start force_start=1
and got 1037
then i tried this:
Here the computer froze, tried it at 2 intervals and it just freezes here.
sudo gdb /usr/bin/Xorg 2>&1 | tee gdb-Xorg.txt
Then on reboot i pressed SHIFT and went into GRUB
I tried to load recovery mode ubuntu but this didn't work.
I tried to get into the terminal there and couldn't do much either nor run the commands above.
Rebooted and went into GRUB again with SHIFT and there i pressed e for edit but i edited nothing and then I just booted the machine from the normal linux 12.04 version that i have.
THEN the boot splash screen looked neat.
I managed to login and then after one minute i got an error message from the system that says:
NOW it hasn't frozen, am doing some updates and wondering what else I can do to make the system stable - also wondering if it wont freeze anymore...
Sorry, Ubuntu 12.04 has experienced an internal error
Executable path: /usr/bin/jockey -gtk and a lot more details related to this.
BUT why is it working ? Might post again in 1 hour...
