I have an older Graphics card in a computer that were hoping to keep with Edubuntu 12.04 for the kids. Its a Nvidia Quadro PCI-E.
I know that I need nvidia-173 driver (mainly used the one provided by Ubuntu from the software centre) but then I just boot to the low-graphics. I have then spent hours going through the posts here and on the ubuntu/support. From what I can tell by the Xorg.0.log, its not compiling the nvidia module.
In my dmesg.0 log there are the lines:
nvidia:module license 'NVIDIA taints kernel'
Disabling lock debugging due to kernel taint
nvidia: module verification failed: signature and/or required key missing - tainting kernel
nvidia: Unknown symbol acpi_os-wait_events-complete (err 0)
Yes this question may be a duplicate of the many out there but I swear I have tried pretty much all the suggested solutions except for the more complicated ones (newbie). I was hoping that the detail in my logs would provide a more precise answer. My monitor is a Princeton. Once in a while I get screen hardware error (not ubunutu but coming from the screen) "Out of Range". Could this also be the screen? Do I need to give up and shell out for a new old computer?
Thanks
