I upgrade my debian testing yesterday. The nvidia-driver and other nvidia packages were upgraded to 430.40-2. Then I found that bumblebee fails to disable discrete graphics card. We can not run opengl software with command "optirun", and when I run command "lspci -nn | grep VGA", I got:
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:3e94] 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107GLM [Quadro P2000 Mobile] [10de:1cba] (rev al) It seem that the nvidia video card can not be disabled. When I run opengl program with optirun or primusrun, the program can not run and I got a error message as below: $ optirun freecad [ 614.056579] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "mouse" (module does not exist, 0) [ 614.056596] [ERROR]Aborting because fallback start is disabled. $ primusrun freecad /usr/bin/primusrun: line 41: warning: command substitution: ignored null byte in input primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Failed to load module "mouse" (module does not exist, 0) My laptop is Thinkpad P1. How do I resolve this error? Thank you very much! Best regards, Gulfstream
