- NVIDIA Geforce 840m Driver Issue 1 answer
I have some issues with nvidia drivers on ubuntu 14.04, switchable graphics (intel HD + nvidia GT 740M).
Currently installed (from xorg-edgers repository):
nvidia-352 (was recommended by ubuntu-drivers devices) +
Issues (appears only when nvidia is selected in prime, with intel no problems):
Blackscreen on login screen (I can hear sound, if I run
startxfrom ctrl-alt-f1 and then stop it, or suspend/standby my pc and turn it on again - display appears).
when using touchpad it freezes every few minutes, and ctrl-alt-f1 then ctrl-alt-f7 unfreezes it. I saw bug report regarding this issue and it was marked as patched/fixed so not sure what the problem is.
Nvidia settings can show temp etc and seems like the driver has good communication with nvidia card.
I tried to
purge nvidia*. I tried using different drivers (nvidia-331). Both cause the same issues.
