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 →

Kernel 4.11 Final is out, a week later than planned, and brief details of changes from -rc8 are here:  http://lkml.iu.edu/hypermail/linux/kernel/1704.3/04608.html As expected, VMware 12.5.5 with the 4.11 patches is still OK (see http://rglinuxtech.com/?p=1932 ), but there is still no ‘legal’ solution for the latest NVIDIA driver – 381.09 (see https://devtalk.nvidia.com/default/topic/1002820/linux/-patch-381-09-kernel-4-11-rc5/ ): ……………..

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 →

NVIDIA – New Driver, Finally OK with Kernel 4.10..

Adventures With Linux ™ Posted on by

NVIDIA have released a new ‘beta’ driver – 381.09 – and release notes etc. are here: http://www.nvidia.com/download/driverResults.aspx/117002/en-us The driver compiles OK with Kernel 4.10 (tested with 4.10.8) but still requires an ‘illegal’ patch for 4.11, due to ongoing code licensing issues..    There is a patch available, and details are here:   https://devtalk.nvidia.com/default/topic/1002820/linux/-patch-381-09-kernel-4-11-rc5/ Robert Gadsdon.   April 6, 2017. … Continue reading →

VMware – 12.5.4 Released – Security Fix Only..

Adventures With Linux ™ Posted on by

Hot on the heel of VMware 12.5.3 comes 12.5.4, and the release notes are here: http://pubs.vmware.com/Release_Notes/en/workstation/12pro/workstation-1254-release-notes.html As can be seen from these notes, this is an urgent-security-fix release only, and the compatibility with Linux kernel versions, and patch applicability, is the same as for 12.5.3 (see http://rglinuxtech.com/?p=1937 ) .      I can confirm that 12.5.4 runs OK on Kernel … Continue reading →

Kernel – 4.11-rc1 and BTRFS – a Warning..?

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 →

UPDATE:  The vmware runtime fix shown here has not worked since version 12.5.6, and the solution is in a later article:  http://rglinuxtech.com/?p=1992 I have recently updated one crash-and-burn system to Fedora 26 (alpha/testing) and have encountered two problems with VMware and the ‘bleeding edge’ version of GCC included.. The first problem sounded very familiar, and it is a … Continue reading →

Adventures With Linux ™ Posted on by

VMware 12.5.3 has been released, and release notes are here:  http://pubs.vmware.com/Release_Notes/en/workstation/12pro/workstation-1253-release-notes.html Although these notes only mention Kernel 4.9.0, I can confirm that it also supports 4.10.x Kernels (tested on 4.10.1). I applied the vmmon and vmnet patches for Kernel 4.11, mentioned in a previous article, and these still worked, and VMware compiled OK, and ran, on 4.11-rc1.. … Continue reading →
