NVIDIA – Another New Driver – 4.11 Fix Still Needed – May be ‘Fixed’ in Kernel, Soon..

Adventures With Linux ™ Posted on by

New NVIDIA driver 381.22 has been released, and details are here:  http://www.nvidia.com/Download/driverResults.aspx/118524/en-us The 4.11 ‘workaround’ still applies (see https://rglinuxtech.com/?p=1970 ). It seems now that the reason the fix was – still – not made by NVIDIA, is that the problem may well be ‘fixed’ in a future Kernel release.. Changes to ‘revert’ the licensing have been proposed, … Continue reading →

Hardware – Inexpensive Small Linux Laptop..

Adventures With Linux ™ Posted on by

After some research, I decided to use an Intel-powered ex-Chromebook for my portable Linux project..    I settled on an Acer Chromebook c720p, as this could be ‘converted’ to run Linux natively, rather than in emulation via Crouton..    There are several articles on this, but I found useful info (and a chassis/mobo diagram) here:  https://ankitrasto.wordpress.com/2015/02/06/clean-installing-linux-on-the-acer-c720pc720-chromebook-a-complete-guide/ If you are … Continue reading →

NVIDIA – Still no 4.11 Solution, but a ‘Good’ Patch for Old Version..

Adventures With Linux ™ Posted on by

Kernel 4.11 ‘final’ has been delayed for a week, and -rc8 has been released..     4.11-patched VMware 12.5.5 is OK, but there is still only a ‘Bad’ (illegal licence modification) patch for the latest NVIDIA driver..   (see https://devtalk.nvidia.com/default/topic/1002820/linux/-patch-381-09-kernel-4-11-rc5/ ) But, if you have an older card, there is a valid patch for driver 340.102 – which does not … Continue reading →

Adventures With Linux ™ Posted on by

I encountered a catastrophic problem with btrfs formatted system disk partition corruption, shortly after updating a test system to Kernel 4.11-rc1. To put this in context, this may be an isolated incident, and I have not seen problems – so far – mentioned elsewhere..    But.. there a quite a lot of BTRFS changes on 4.11, and – … Continue reading →
