I tried to install Ubuntu 14.04.01, but I ran into serious problems (details here)
I have installed 12.04.05 instead, but I still have serious problems. After installing I reboot, the system starts ok, a window opens up about upgrade to 14.04, I decline and the window closes. I can see the bar at the top of the screen, but launcher is missing and now the ui is frozen: I can't click anything, right-click won't open the menu.
When I press ctrl-alt-f1 there is a error message at the tty:
could not write bytes: Broken pipe - [ 929.157700] nouveau E[ DRM] GPU lockup - swithing to software fbcon
If I idle on the tty these messages appear:
[ 1070.992016] nouveau E[Xorg failed to idle channel 0xcccc0000 [Xorg]
There are several of them, the numbers change, but the text and the channel stays the same. If I idle long enough the desktop is swithced on and I have to log in and the top bar is missing.
My computer: Intel D865PERL, Pentium 4 CPU (3 Ghz), 3 Gb RAM, and NVIDIA Quadro FX 500/600 graphics card. I have a harddrive with two partitions: one for the XP and one for Ubuntu and it's partitions.
I think the problem is with the drivers, so I press ctrl-alt-F1 and install the drivers using these instructions via tty :
sudo add-apt-repository ppa:xorg-edgers/ppa -y sudo apt-get update sudo apt-get install nvidia-173
Then I type
lspci -vnn | grep -i VGA -A 12 and everything seems ok except that
Kernel driver in use: nouveau
The next line is
Kernel modules: nvidia_173, nouveau, nvidiafb
After reboot I get this After this "OK" -> "Reconfigure graphics" -> "Use default (generic) configuration" OR "Use your backed-up configuration" -> nothing happens
If I choose "use low-graphics mode just for this session" the system freezes.
How could I solve this? I seems clear that the problem lies with the Nvidia driver. Would it help if I changed the kernel driver from nouveau to nvidia_173 ? How can I do that? I can find advice on how to do it in unity with dash, but how can I do it in tty?
SOLUTION: Using the latest drivers helped. I should have installed the 304 version in the first place instead of the 173 version I used (that was the version I used in my XP)
