Major Update to Debian / Stretch Today

I have two computers running Debian / Stretch, which is the code-name for Debian 9. I name those computers ‘Phosphene’ and ‘Klexel’. Debian 9 has just received a major update, from Debian 9.9 to Debian 9.10. At the same time, this update installed a kernel update on both machines.

As far as I can tell, the upgrade went smoothly on both machines.

Update to Computer Phosphene Last Night

Yesterday evening, a major software update was received to the computer which I name ‘Phosphene’, putting its Debian version to 9.9 from 9.8. One of the main features of the update was, an update to the NVIDIA graphics drivers, as installed from the standard Debian repositories, to version 390.116.

This allows the maximum OpenGL version supported by the drivers to be 4.6.0, and for the first time, I’m noticing that my hardware now limits me to OpenGL 4.5 .

The new driver version does not come with an update to the CUDA version, the latter of which merits some comment. When users install CUDA to Debian / Stretch from the repositories, they obtain run-time version 8.0.44, even though the newly-updated drivers support CUDA all the way up to version 9. This is a shame because CUDA 8.0 cannot be linked to, when compiling code on the GCC / CPP / C++ 6 framework, that is also standard for Debian Stretch. When we want code to run on the GPGPU, we can just load the code onto the GPU using the CUDA run-time v8.0.44, and it runs fine. But if we want to compile major software against the headers, we are locked out. The current Compiler version is too high, for this older CUDA Run-Time version. (:1) (:4)

But on the other side of this irony, I just performed an extension of my own by installing ‘ArrayFire‘ v3.6.3 , coincidentally directly after this update. And my first attempt to do so involved the binary installer that ships with its own CUDA run-time libraries, those being of version 10. Guess what, Driver version 390 is still not high enough to accommodate Run-Time version 10. This resulted in a confusing error message at first, stating that the driver was not high enough, apparently to accommodate the run-time installed system-wide, which would have been bad news for me, as it would have meant a deeply misconfigured setup – and a newly-botched update. It was only after learning that the binary installer for ArrayFire ships with its own CUDA run-time, that I was relieved to know that the┬ásystem-installed run-time, was fine…

Major Update, On Computer ‘Plato’

(As of 20h30 : )

One fact which may confuse some of my readers, is that I have more than one computer. The server of my Web-site and blog, is a Debian / Jessie, Debian 8 system called ‘Phoenix’.

But a much-more interesting computer is a Debian / Stretch, Debian 9 system called ‘Plato’. That is an early, 8-core machine with 12GB of RAM, which does not act as much of a server, but that has an NVidia GeForce GTX460 graphics card, with proprietary drivers.

This evening, ‘Plato’ received a set of updates, that both upgraded its Linux version from Debian 9.4 to Debian 9.5, as well as upgrading its graphics drivers. Aside from some minor misbehavior before the required reboot, the updates seemed to take place smoothly. However, I must now test my graphics capabilities, and all things related to its GPU.

‘Plato’ also received an update to its CUDA drivers.

(Update 21h10 : )

On the computer I name ‘Plato’, I can still play the game ‘Quern – Undying Thoughts’ (through my Steam account), and The LuxCore Render still works, which verifies my OpenCL capabilities.

I never did a thorough test of the CUDA capabilities, but because my NVidia control panel still tells me I have 336 CUDA cores, I’m assuming its basic functionality is still intact.

Major System Update Today, Downtime

I go the unusual route, Of hosting my Web-site and therefore also this blog, on one of my own private computers at home, that is named ‘Phoenix’. Therefore, the availability of my blog is only as good, as that of my PC.

This evening the Debian / Jessie repositories pushed through a major update, which turned my Debian 8.10 system into a Debian 8.11 system. Additionally, this included an update to the proprietary, legacy nVidia graphics driver, version 304.x , which is pretty much the only device-driver left, which will work with an old on-board graphics chip, which was the:

GeForce 6150SE nForce 430/integrated/SSE2

Hence, if after the update, the X-server had not restarted, I would pretty much have been finished with this computer!

Luckily, the graphics-driver update seemed to take well, and the whole procedure seemed to go smoothly.

Due to the reboot which was required, my site and blog were off-line, from about 20h05 until about 20h10. Because this was only for 5 minutes, I’m sure this did not inconvenience my readers much.
