Hi,
From the beginning of February 2016 I cannot start X with my Nvidia Optimus, so I can only use Intel graphics.
Gentoo ~amd64 Linux & Nvidia 630M 1GB.
I use (and tested):
kernel: 4.5.0-r1 (4.4.6 - 4.5.0)
nvidia proprietary drivers: 364.12-r1 (346.96 - 361.28)
xorg-server: 1.18.2 (1.16.4 - 1.18.1)
intel drivers: 2.99.917_p20160324
To have working X, I use startx form text console and Xorg.0.log shows only 1 error:
(EE) modeset(G0): failed to set mode: No space left on device
^^ When I was searching Google, looks like this error was only in Gentoo. No idea what’s wrong.
I have such error on the screen after typing ‘startx’ from the console:
xrandr: Configure crtc 2 failed
X Error of failed request: BadValue (integer parameter out of range for operation)
Major Opcode of failed request: 139 (RANDR)
Minor Opcode of failed request: 21 (RRSetCrtcConfig)
Value in failed request: 0x0
Serial number of failed request: 45
Current serial number in output stream: 45
xinit: connection to X server lost
Everything is as should be in Nvidia guide:
