I have a NVIDIA GeForce 940MX graphics card, and I've installed Linux Mint 18 on this laptop. If I switch to this card in the driver manager, Mint crashes. How am I to go about using this card?

Diver Manager Screenshot:

I also keep getting this "No hardware acceleration notification: Cinnamon is currently running without video hardware acceleration and, as a result, you may observe much higher than normal CPU usage.

it looks like you have installed latest driver can you please share crashlog or dmesg just after you use change use the graphics card. As per this it should work directly after you install driver.

so I don't see a problem. and both errors are pretty normal when you don't select graphics card.

So waiting for message log

  • How do I view to crashlog/dmesg?

  • The NVIDIA page keeps asking me to install Java. But I already have it installed. java -version yeilds this: openjdk version "9-internal" OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src) OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode) Also, the dmesg log outputs this error: [ 0.991258] checking generic (b0000000 7f0000) vs hw (d0000000 2000000) [ 0.991268] nouveau 0000:01:00.0: enabling device (0006 -> 0007) [ 0.991301] nouveau 0000:01:00.0: unknown chipset (1180d0a2)

  • @Mihir, according to the dmesg log you have provided. It points out that drivers are not installed properly or card is not inserted properly. Please check hardware connection and if possible check it with other OS if this card is working properly. Also check with this command lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' and send the output this checks which are pci devices connected. and also check this command lsmod to check which of the drivers currently loaded

  • According to this image you sent It is clear that Graphics card is not installed (software / hardware) properly. and second command is for to check which drivers are used currently to check whether driver is invoked or not ?
