bumblebee fails to disable discrete graphics card after upgrade nvidia driver to 430.40-2
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
Does not Debian support mobile broadband anymore?
Hi, everyone, Since my Debian testing was upgraded on Oct 29, the mobile broadband in my laptop could not be used. The mobile broadband is missing in the network-manager UI, and wvdialconf can not configure the broadband either. The message of wvdialconf is as below, ** Editing `/etc/wvdial.conf'. Scanning your serial ports for a modem. ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.

Sorry, no modem was detected! Is it in use by another program? Did you configure it properly with setserial? Please read the FAQ at http://alumnit.ca/wiki/?WvDial *** My laptop is Thinkpad X1 Carbon 5th, and its mobile broadband device is Sierra Wireless EM7455. This function works fine before the upgrading. Does not Debian support mobile broadband anymore? Or who known how to resolve this problem? Thank you very much! Best regards, Gulfstream
Bluetooth mouse disconnect while laptop runs with cell
Hi, everyone! I use my laptop (Thinkpad X1 Carbon 5th) with a bluetooth mouse. The mouse work fine while the laptop runs with AC power supply. But The bluetooth mouse is a trouble while the laptop runs with the embed cell. The mouse will disconnect if it is not be used after several seconds. So I want use the mouse, it must reconnect to the laptop and spend several seconds. it is very inconvenient! I think the reason is the function of bluetooth power save while the cell is used. So I want to turn off the function of bluetooth power save, but I can not find where to define it. Would you please tell me how to turn off the function of bluetooth power save? My Debian version is the buster, and it is upgraded everyday. Best regards, Gulfstream
