So, I recently got a notification that my Hardware Enablement Stack (HWE) was no longer going to be supported, so I had to perform an upgrade. I didn’t have time to move to 14.04, so I just did the HWE upgrade.
Unfortunately when I rebooted, I no longer had 3D support, and worse, my twin monitor setup was no longer supported (or rather, both monitors were active, but showed the same thing!).
I am rocking a NVIDIA GeForce GT 610, which, although it’s a basic card, doesn’t seem to be supported very well by Ubuntu’s native Nvidia drivers. When I ran
nvidia-detector, no cards were found.
Since my card was working before, I figured it was probably just a driver problem.
The solution I used for this was to update the Nvidia drivers to use the Nvidia proprietary drivers. Here’s how…
- First, visit the Nvidia website and use the wizard to download the correct driver bundle for your card.
- Hit Alt-F1 to enter a console
- Uninstall the existing Nvidia drivers:
sudo apt-get remove --purge nvidia-*
- Move the old Xorg config out of the way:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.orig1
- Stop X:
sudo stop lightdm
- Run the NVidia installer (Note, you may need to reboot and re-run steps 5 & 6, as the installer may have to disable some kernel modules). Save yourself a headache, and be sure to build the DKMS module, so that changes aren’t lost when ubuntu updates itself.
All going well, you should now have working Nvidia drivers with two screen support!
