Out of memory issue with Vivado Installer

It shouldn’t be a common issue that one wants to install a development suite such as Vivado in a system with not a lot of memory. But it so happens that I tried it on my laptop with 8 GB physical RAM and only 2 GB swap space. The error that the installer shows is not very helpful:

# ./Xilinx_Vivado_SDK_Web_2017.4_1216_1_Lin64.bin
Verifying archive integrity… All good.

INFO : Log file location – /root/.Xilinx/xinstall/xinstall_1543839793529.log./xsetup: line 71: 16291 Killed ${X_JAVA_HOME}/bin/java ${ARGS} -splash:${root}/data/images/splash.png -jar ${root}/lib/classes/xinstaller.jar

But ‘dmesg’ shows much more useful information:

[1459339.152707] Out of memory: Kill process 16291 (java) score 168 or sacrifice child
[1459339.152760] Killed process 16291 (java) total-vm:5680084kB, anon-rss:1753772kB, file-rss:0kB, shmem-rss:1024kB
[1459339.263118] oom_reaper: reaped process 16291 (java), now anon-rss:0kB, file-rss:0kB, shmem-rss:1024kB

Hence, the solution was to just close Firefox and Thunderbird, which had been running for a while (months?).

VidyoDesktop autostart on login under Linux

Your VidyoDesktop client on Linux always starts when you login no matter your settings? I mean, you unset “Start VidyoDesktop on login” and it’s ignoring you? Solution:

rm ~/.config/autostart/VidyoDesktop.desktop
sudo rm /etc/xdg/autostart/VidyoDesktop.desktop

Why the option doesn’t work is beyond me, but this does.

Reading spree: What If?

Wow, almost another year of hardly even looking at the blog. So what am I up to? Working quite a bit on the ATLAS Phase II Upgrade in Freiburg, with a new life in Germany and getting a little bit in better shape.

And also reading, quite a few books. Although work and the new life in Germany keeps me very busy, I still enjoy the occasional book, usually just devouring them. The last one was What If?, by Randall Munroe from the xkcd webcomic.

It’s a very interesting and enjoyable piece of work, suitable for people who know nothing about science or world class physicists 🙂
