Message: 'Input: MTDev is not supported by your version of linux'

[Pete Kovac]

This one really stumps me - I was working on my project and then lost power. I rebooted back up and started to work on my project again. I went to compile and poof I get an error I've never seen before, my project was working fine before the power went out. 

I get this error

Message: 'Input: MTDev is not supported by your version of linux'

Here is the full error that pyCharm is giving me:

System is a Linux Mint 64 box with Nvidia Drivers installed and working correctly. 

Thanks for any help as Google only has old information from way back in 2014. 

[Pete Kovac]

Interesting that it is something with the NVIDIA drivers - I fell back to the open source drivers and everything works as it was before. The only thing with these open source graphics drivers is that they lock up my system after a few mins of use. Guess I'll have fun purging NVIDIA and re-installing. This should be fun, don't we all love setbacks :)

nvidia proprietary drivers are not backward compatible.

someone recently on a freebsd groups posted bug that it is impossible to use kicad because of egl because of gtk because od dri because of nvidia kernel driver for older cards. long stort short old drivers 3xx had some calls but modern api changed so nothing works anymore and there os no really good open source alternative. 

after using nvidia for 20 years i switched to amd and will never come back.

also i stopped using linux around 2.4.10 when kernel api started changing every minor and i had to fix gfx drivers by hand.

unfortunately linux drives the current drm kms directions so i expect nothing good.

welcome to world of enforced changes because according to microsoft development is about enforcing changes ;-)

its insane - looks like my power going out wasnt the issue, looking more into your post sure enough there was an update and caused issues with my Nvidia card - I ended up going back to a very old snapshot and have been rebuilding and saving snapshots as I go forward. If anyone out there is running a "legacy" Nvidia card on drivers 470 take snapshots and make sure not to upgrade packages. NOT LEGAL ADVICE - DO WHAT YOU WANT 

Almost back to 100% on the system - insane I've lost all this time to get my application done by the end of the year. Thanks for the help bud!
