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.



Simultaneous Update on Debian / Stretch Seems To Fix Wayland Bug, But An Effect Breaks.

This morning was one, on which most of my computers are receiving major system updates.

On the computer that acts as my Web-server, which I name ‘Phoenix’, this updated my Debian / Jessie version from 8.9 to 8.10.

On the computer which I most-recently installed, which I name ‘Plato’, this updated my Debian / Stretch version from 9.2 to 9.3 .

On both computers, this included a kernel-update. Additionally, it included an update, to the client-side X-server libraries. This posting has to do with the computer named ‘Plato’, which has kernel version ‘4.9.0-4-amd64′ now.

Previously I had blogged, that the computer named ‘Plato’ was suffering from a mysterious bug in its ‘Wayland’ compositor. If the compositing became suspended for any reason, after resuming, black rectangles would appear on the screen, as newly-opened windows faded in and out. This used to happen regardless of whether OpenGL 2 or OpenGL 3 compositing was being used.

Well since the update today, I tested the key-combination <Shift>+<Alt>+F12 again, which does the equivalent of sending the command to the compositor, to suspend. Apparently, the behavior of this key-combination has been changed since Debian / Jessie, so that instead of toggling, the compositing suspends for several seconds, and then automatically resumes. This would be useless as a user-feature, but can help with testing, because presumably, what an OpenGL application is supposed to do, is resend the signal every second or so, to make sure that compositing stays off.

To my pleasant surprise, I found that after compositing resumes, I no longer get black rectangles on the screen! :-)

System Update Today, Downtime

I take the unusual measure, of hosting my Web-site, and therefore also this blog, on a PC running at home. The PC I use is the Debian / Jessie (Linux) computer I name ‘Phoenix’.

This morning, I installed a major set of updates on this computer, which included 137 packages, and doing so, brought it from Debian version 8.9 to version 8.10 .

But, because this PC is also my Web-server, the required reboot also meant, that the site was offline from about 10h20 until about 10h30.

I apologize for any inconvenience.

BTW, ‘Phoenix’ had been Up, for 62 straight days.

It’s too early really to tell, whether this large an update has affected reliability adversely, but they usually do not. So for now, I’m counting this as a successful update.
