i am fairly new to LMDE, have installed every update that is available and so far everything runs fine, as long as i am not changing the graphics driver. In that case, only the internal Intel chip of my optimus card GT540M will be used. So i was trying to get the dedicated graphics to work, but could not accomplish that yet.
After searching for a solution with just nvidia proprietary drivers, i found Bumblebee to be the only solution for optimus cards. After following the official How To and trying some solutions given in google search results, i still do not get it to work properly. But most of the reasons for Bumblebee not working i have found, have been changed and optimized in the current Bumblebee package from the LMDE sources. And it seems that it works for almost everyone now, by just installing it, without any further configuration.
After installing Bumblebee with
Code: Select all
sudo apt-get install bumblebee-nvidia primus
glxgears works before installation, but after it:
Code: Select all
glxgears
Xlib: extension "GLX" missing on display ":0".
Error: couldn't get an RGB, Double-buffered visual
Code: Select all
optirun glxgears
Xlib: extension "GLX" missing on display ":0".
Xlib: extension "GLX" missing on display ":0".
Error: couldn't get an RGB, Double-buffered visual
Code: Select all
sudo apt-get install --reinstall libgl1-mesa-glx xserver-xorg-core
inxi -G
delivers the following output without Bumblebee:

optirun nvidia-settings -c :8
So far i understand, that the install process messes up the driver for the integrated chip, but from what i learned, this should not happen anymore. After just removing bumblebee and everything nvidia related, everything works fine again with only the Intel chip working.
This is the very first time i start a thread myself, because i was always able to get help from threads of other people for every single problem i encountered in my live. So please be patient, if i made a mistake somewhere. But i am really impressed by LMDE after many years of not caring about Linux and only using Windows. So i really hope, i can get help with getting my nvidia graphics to run properly and not having to abandon LMDE. I could post the whole terminal output of the Bumblebee installation, if necessary.
Thanks in advance
