I have an older laptop that I use to watch movies on my TV. It is connected to the TV and I use the TV as a “projector”. The resolution of our HD-ready TV is 1152×864. I also set this resolution on the laptop and the screen was cloned on the TV. It can be set with nvidia-settings easily. Everything worked fine for years when suddenly…
…I clicked on the “Update” button. And it updated the Nvidia driver. And from then on I couldn’t change the resolution. Aaaarrrrrghhhhh!
The nvidia driver offered one resolution only: the highest one, which is 1900×1200. It would be fine for my laptop but I want to clone the screen on the TV which doesn’t support such high resolution. Damn!
I tried everything. For hours. And finally I found the solution: I managed to downgrade the nvidia driver from 304.88 to 295.33.
nvidia graphics drivers: here
Note that the version of nvidia-settings must match the version of nvidia graphics driver!
So I downloaded the following files:
nvidia-current_295.33-0ubuntu1_i386.deb nvidia-current-dev_295.33-0ubuntu1_i386.deb nvidia-settings_295.33-0ubuntu1_i386.deb
I removed the current nvidia packages and then installed the 3 packages above. Here I suppose that the 3 files above are saved in a folder and you entered that folder.
sudo apt-get purge nvidia-* sudo dpkg -i *
After restarting the machine it worked fine. On this laptop I will never ever update the nvidia driver, that’s sure as hell.
The downgrade tip is from here.
So far I’ve upgraded two machines. I like the new Ubuntu (though it looks and feels like 12.10 :)) but the upgrade was not as smooth as before.
First, on my workplace machine the upgrade process stopped at 30% and the machine simply froze down. I could move the mouse but nothing else worked. Even the clock in the top right corner stopped. I gave it a try, restarted the machine and to my greatest surprise it came back alive and I even had a graphical interface. Wow! With my good_shape_safe.sh script (it’s the second one) I could continue the upgrade process and it finished in order. After a reboot I had a fully functional Ubuntu 13.04.
Second, my home desktop was upgraded without any freeze :) I brought home the update packages and thus the upgrade process finished in an hour. However, after reboot the X started in low resolution. When I launched “
nvidia-settings“, it said that my Nvidia card was not enabled and I should re-generate the xorg.conf file. It told me how to do that so I copied/pasted that line to a terminal. After that I reinstalled the nvidia packages:
sudo apt-get --purge remove nvidia-* sudo apt-get install nvidia-current nvidia-settings
After restarting the X (“
sudo service lightdm restart“) the resolution was fine.
However, the torture was not over yet. The graphical interface (Unity) got messed up: the launcher didn’t appear; the Super key (Windows button) didn’t bring up the Dash; the top panel was covered by a Gnome2-ish panel, etc. Fortunately, I found a script that could reset my Unity: https://github.com/phanimahesh/unity-revamp. It worked perfectly and my Unity became usable again. With “ubuntu-tweak” I could fine-tune my new Ubuntu and now it looks like my 12.10 :)

This morning my Ubuntu got f* up completely. I was at the point that I reinstall the whole s* from scratch. Strangely, after some restarts it started to work OK. So, here is what happened.
First, after restart I got a blank screen. No X, nothing. I couldn’t even switch to console with Ctrl+Alt+F1. After a reset I got the graphical interface. But after a restart no X again. It was alternating… I edited the file “
/etc/default/grub” and changed this line:
Now at least I could follow the bootup sequence and noticed that the boot stopped after mounting the swap partition. Following this post I could fix the swap partition. I am not 100% sure that it was the problem since I also installed a newer version of the nvidia driver.
Fixing the swap partition:
# run "sudo gparted" and figure out the partition of the swap # for me it was /dev/sda2 sudo swapoff /dev/sda2 sudo mkswap /dev/sda2 sudo swapon /dev/sda2 sudo update-initramfs -u
Update the nvidia driver:
# previous version: 304.88 sudo apt-get --purge remove nvidia-* sudo apt-get install nvidia-313 nvidia-settings-313
Now the blank screen problem was solved. However, I couldn’t stop the machine. It displayed “
* Will now restart” but nothing happened. Again, I had to poke the “
More info here. Now it seems OK. Damn, if I had known that I’d have so many problems, I wouldn’t have upgraded to 13.04…

My upgraded Ubuntu 13.04 continued to behave strangely. I got fed up with that and today I reinstalled it from scratch. Now it works correctly. Something must have happened to it during the upgrade…
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-current nvidia-settings
It’s Friday (at last) and this week was quite good, so here is some fun:
