Nvidia / Ati issues
This happens when a driver has a problem installing correctly (Most cases). For this do the following:
- Boot PC leaving SHIFT pressed to make the GRUB Menu show.
- Select Recovery Mode which will continue booting correctly until the Recovery Menu appeares.
- Select from the recovery menu failsafeX.
- In some cases failsafeX will load fine (You lucky dog), for others (Me) it will give an error along the lines of “The system is running in low-graphics mode” and will stay there forever. When this happens, press CTRL+ALT+F1 to go to the terminal. Type in your Username and Password.
- Reinstall the drivers depending on your case:NVIDIA
sudo apt-get install nvidia-current– More stable/tested version
sudo apt-get install nvidia-current-updates– More up-to-date version
For other cases see this answer for details and follow the links there to help you along the way.
The simple way is to
sudo apt-get install fglrx. If this does not work keep reading.
Go to http://support.amd.com/us/gpudownload/Pages/index.aspx, download the one you need, put it in some folder (rename it to “ati.run” to simplify name). Go to the folder where you downloaded the file and type
chmod +x ati.runto give it Executable Permission. Now just simply
./sh ati.runand follow the onscreen steps.
After rebooting all problems should be solved. If you test ‘Additional Drivers’ with a problem like this it will finish downloading the package but then it will give an error. It also gives the same error if you use ‘Software Center’ and ‘Synaptic’. The only way was to go to the
failsafeXoption and do the workaround about changing to the
tty1terminal and doing it via command line.
I also need to add that I do not recommend downloading the Drivers from the Nvidia site since they:
- Might create additional problems with Ubuntu
- Are not updated automatically
- Are not tested thoroughly in Ubuntu
Always use the
nvidia-currentpackage or the
nvidia-current-updatesone. This are tested and approved already for the Ubuntu version you are using and will give less errors and incompatibility bugs.
For Intel it is recommended to do the following after doing all the steps mentioned above but before installing anything (When you are in the Terminal). You can choose from the Xorg-Edgers which is an Unstable PPA or the X-Swat which is more stable:
Warning: This PPA is very unstable for some things. So do it with that in mind.
sudo add-apt-repository ppa:xorg-edgers/ppa -y
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates -y
sudo apt-get updateand you should receive several updates. X-Swat currently does not have Intel drivers in the latest versions of Ubuntu.
- Only for ATI graphics cardsWhen the message that “your system is running in low-graphics mode” appears:
Press Ctrl+Alt+F1 to see the terminal one. Then login with your credentials, and then run the following commands:
sudo apt-get install fglrx sudo reboot
Goto Additional drivers and remove the dirver. You have to mark the Using X.Org X server — Nouveau.
- Follow these commands:
sudo apt-get update sudo apt-get -d install --reinstall gdm sudo apt-get remove --purge gdm
(I ran this command above, but was told by the system to use # sudo apt-get autoremove instead, after the #sudo apt-get remove –purge gdm command.)
sudo apt-get install gdm
select GDM when prompted
You have too many files on your computer, and have exhausted disk space
Try moving personal files off the computer onto a USB drive.
To check whether this is the issue:
- Press Ctrl + Alt + F1
- If you see that there is no space available on the root (
/) then you need to free some space.
To free space you can:
sudo apt-get autoclean
- Look for large directories with
sudo du -sc /*/* |sort -gand delete unwanted content,
- Clean your home directory using a combination of
cd ~ du -sc * |sort -g rm myLargeFile
When this is done, restart:
shutdown -r now
